3.0 Applicable standards and reference documentation

The drives documented in this manual have been developed as system peripherals to the highest standards of design and construction. The drives depend on host equipment to provide adequate power and environment for optimum performance and compliance with applicable industry and governmental regulations. Special attention must be given in the areas o f safety, power distribution, shielding, audible noise control, and temperature regulation. In particular, the drives must be securely mounted to guarantee the specified performance characteristics. Mounting by bottom holes must meet the requirements of Section 9.4.

3.1 Standards

The Savvio family complies with Seagate standards as noted in the a ppropriate sectio ns of this manual and the Seagate FC Interface Manual, part number 100293070.

The drives are recognized in accordance with UL 60950 and CSA 60950 as tested by UL(CSA) and EN60950 as tested by TUV.

3.1.1 Electromagnetic compatibility

The drive, as delivered, is designed for system integration and installation into a suitable enclosure prior to use. As such the drive is supplied as a subassembly and is not subject to Subpart B of Part 15 of the FCC Rules and Regulations nor the Radio Interference Regulations of the Canadian Department of Communications.

The design characteristics of the drive serve to minimize radiation when installed in an enclosure that provides reasonable shielding. The drive is capable of meeting the Class B limits of the FCC Rules and Regulations of the Canadian Department of Communications when properly packaged; however, it is the user’s responsibility to assure that the drive meets the appropriate EMI requirements in their system. Shielded I/O cables may be required if the enclosure does not provide adequate shielding. If the I/O cables ar e external to the enclosure, shielded cables should be used, with the shields grounded to the enclosure and to the host controller.

3.1.1.1 Electromagnetic susceptibility

As a component assembly, the drive is not required to meet any susceptibility performance requirements. It is the responsibility of those integrating the drive within their systems to perform those tests required and design their system to ensure that equipment operating in the same system as the drive or external to the system does not adversely affect the performance of the drive. See Tables 2 through 5, DC power requirements.

3.2 European Union Restriction of Hazardous Substances (RoHS)

The European Union Restriction of Hazardous Substances (RoHS) Directive restricts the presence of chemical substances, including Lead (Pb), in electronic products effective July 2006.

A number of parts and materials in Seagate products are procured from external suppliers. We rely on the representations of our suppliers regarding the presence of RoHS substances in these parts and materials. Our supplier contracts require compliance with our ch emical substance restrictions, and our suppliers document their compliance with our requirements by providing material conten t declarations for all p arts and materials for the disk drives documented in this publication. Current supplier declarations include disclosure of the inclusion of any RoHS-regulated substance in such parts or materials.

Seagate also has internal systems in place to ensure on going compliance with the RoHS Directive and all laws and regulations which restrict chemical content in electronic products. These systems include st andard ope rating procedures that ensure that restricted substances are not utilized in our manufacturing operations, laboratory analytical validation testing, and an internal auditing process to ensure that all standard operating procedures are complied with.

4.0 General description

Savvio 10K.5 FC drives provide high performance, high capacity dat a storage for a variety of systems including engineering workstations, network servers, mainframes, and supercomputer s. Savvio 10K.5 F C drive s suppo rt 4-Gb Fibre Channel which can transfer data at up to 800MBs per second and 1600MBs per second in dualloop configurations.

Savvio 10K.5 FC drives support the Fibre Channel Arbitrated Loop (FC-AL) and SCSI Fibre Channel Protocol as described in the ANSI specifications, this document, and the Fibre Channel Interface Manual which describes the general interface characteristics of this drive. Savvio 10K.5 FC drives are classified as intelligent peripherals and provide level 2 conformance (highest level) with the ANSI SCSI-1 standard.

Note. Never disassemble the HDA and do not attempt to service items in the sealed enclosure (h eads, media, actuator,

etc.) as this requires special facilities. The drive does not contain user-replaceable parts. Opening the HDA for any reason voids your warranty.

Savvio drives use a dedicated load/u nload zo ne at the o utermost radius of the media to eliminate the possibility of destroying or degrading data by landing in the data zone. The heads automatically go to the ramp load/ unload when power is removed from the drive.

An automatic shipping lock prevents potential damage to the heads and disks that results from movement during shipping and handling. The shipping lock disengages and the head load process begins when power is applied to the drive.

The drives also use a high-performance actuator assembly with a low-inertia, balanced, patented, straight arm design that provides excellent performance with minimal power dissipation.

4.5 Formatted capacities

Sta ndard OEM mode ls are for matted to 512 bytes pe r block. The sector size is select able at format time. Use rs having the necessary equipment may modify the data block size before issuing a format command and obtain different formatted capacities than those listed.

To provide a stable target capacity environment and at the same time provide users with flexibility if they choose, Seagate recommends product planning in one of two modes:

1. Seagate designs specify capacity points at certain sector sizes that Seagate guarantees current and future roducts will meet. We recommend customers use this capacity in their project planning, as it ensures a

p stable operating point with backward and forward compatibility from generation to generation. The current guaranteed operating points for this product are:

2. Seagate drives also ma y be used at the m aximum availa ble cap acity at a given sector size, but the excess

capacity above the guaranteed level will vary between 10K and 15K families and from generation to generation, depending on how each sector size actually formats out for zone frequencies and splits over servo

ursts. This added capacity potential may range from 0.1 to 1.3 percent above the guaranteed capacities

b listed above. Using the drives in this manner gives the absolute maximum capacity potential, but the user must determine if the extra capacity potential is useful, or whether their assurance of backward and forward compatibility t

akes precedence.

8 Savvio 10K.5 FC Product Manual, Rev. D

4.6 Programmable drive capacity

Using the Mode Select command, the drive can change its capacity to something less than maximum. See the Mode Select Parameter List table in the SCSI Co mmands Refe ren c e Manu al . Refer to the Parameter list block descriptor number of blocks field. A value of zero in the number of blocks field indicates that the drive shall not change the capacity it is currently formatted to have. A number in the number of blocks field that is less than the maximum number of LBAs changes the total drive capacity to the value in the block descriptor number of blocks field. A value greater than the maximum number of LBAs is rounded down to the maximum capacity.

4.7 Factory-installed options

You may order the following items which are incorporated at the manufacturing facility during production or packaged before shipping. Some of the options available are (not an exhaustive list of possible options):

• Other capacities can be ordered depending on sparing scheme and sector size requested.

• Single-unit shipping pack. The drive is normally shipped in bulk packaging to provide maximum protection against transit damage. Units shipped individually require additional protection as p rovided by the sin gle unit shipping pack. Users planning single unit distribution should specify this option.

•The Safety and Regulatory Agency Specifications, part number 75789512, is usually included with each standard OEM drive shipped, but extra copies may be ordered.

5.3 Start/stop time

If the Motor Start option is disabled, the drive becomes ready within 20 seconds after DC power is applied. If a recoverable error condition is detected during the st art sequence, the drive executes a recovery proced ure and the time to become ready may exceed 20 seconds. During spin up to ready time, the drive responds to some commands over the FC interface in less than 3 seconds after application of power. Stop time is 30 seconds (maximum) from removal of DC power.

If the Motor Start option is enabled, the internal controller accepts the commands listed in the Fibre Channel Interface Manual less than 3 seconds after DC power has been applied. After the Motor Start command has been received, the drive becomes ready for normal operations within 20 seconds (excluding the error recovery procedure). The Motor Start command can also be used to command the drive to stop the spindle.

There is no power control switch on the drive.

5.4 Prefetch/multi-segmented cache control

The drive provides a prefetch (read look-ahead) and multi-segmented cache control algorithms that in many cases can enhance system performance. Cache refers to the drive buffer storage space when it is used in cache operations. To select this feature, the host sends the Mode Select command with the proper values in the applicable bytes in page 08h. Prefetch and cache operations ar e independent features from the standpoint that each is enabled and disabled independently using the Mode Select command; however, in actual operation, the prefetch feature overlaps cache operation somewhat as described in sections 5.5.1 and 5.5.2.

All default cache and prefetch mode parameter values (Mode Page 08h) for standard OEM versions of this drive family are given in Section 10.3.2

Savvio 10K.5 FC Product Manual, Rev. D 11

5.5 Cache operation

Note. Refer to the Fibre Channel Interface Manual for more detail concerning the cache bits.

Of the 64 Mbytes physical buffer space in the drive, approximately 30,000 kbytes are available as a data cache. The remaining buffer space is reserved for internal drive use.

The drive keeps track of the logical block addresses of the data stored in each segment of the buffer. If the cache is enabled (see RCD bit in the FC Interface Manual ), data requested by the host with a read command is retrieved from the buffer , if po ssible, before any disk acce ss is initiated. If cache operation is not enabled, the buffer is still used, but only as circular buffer segments during disk medium read operations (disregarding Prefetch operation for the moment). That is, the drive does not check in the buffer segments for the requested read data, but goes directly to the medium to retrieve it. The retrieved data merely passes through some buffer segment on the way to the host. All data transfers to the host are in accordance with buffer-full ratio rules. See the explanation provided with the information about Mode Page 02h ( disconnect/reconn ect control) in the Fibre Channel Interface Manual.

The following is a simplified description of the prefetch/cache operation: Case A—read command is received and all of the requested logical blocks are already in the cache:

1. Drive transfers the requested logical blocks to the initiator.

Case B—A Read command requests data, and at least one requested logical block is not in any segment of the cache:

1. The drive fetches the requested logical blocks from the disk and transfers them into a segm ent, and then

from there to the host in accordance with the Mode Select Disconnect/Reconnect parameters, page 02h.

2. If the prefetch feature is enabled, refer to section 5.5.2 for operation from this point.

Each cache segment is actually a self-contained circular buffer whose length is an integer number of logical blocks. The drive dynamically creates and removes segments based on the workload. The wrap-around capability of the individual segments greatly enhances the cache’s overall performance.

Note. The size of each segment is not reported by Mode Sense command page 08h, bytes 14 and 15. The value 0XFFFF

is always reported regardless of the actual size of the segment. Sending a size specifi cation using the Mode Select command (bytes 14 and 15) does not set up a new segment size. If the STRICT bit in Mode page 00h (byte 2, bit 1) is set to one, the drive responds as it does for any attempt to change an unchangeable parameter.

12 Savvio 10K.5 FC Product Manual, Rev. D

5.5.1 Caching write data

Write caching is a write operation by the drive that make s use of a drive b uffer storage area wher e the da ta to be written to the medium is stored while the drive performs the Write command.

If read caching is enabled (RCD=0), then data written to the medium is retained in the cache to be made available for future read cache hits. The same buffer space and segmentation is used as set up for read functions. The buffer segmentation scheme is set up or changed independently, having nothing to do with the state of RCD. When a write command is issued, if RCD=0, the cache is first checked to see if any logical blocks that are to be written are already stored in th e cache from a previous read or write command. If there are, the respective cache segments are cleared. The new data is cached for subsequent Read commands.

If the number of write data logical blocks exceed the size of the segme nt being written into, when the end of the segment is reached, the data is written into the beginning of the same cache segment, overwriting the da ta that was written there at the beginning of the operation; however, the drive does not overwrite data that has not yet been written to the medium.

If write caching is enabled (WCE=1), then the drive may return Good status on a write command after the data has been transferred into the cache, but before the data has been written to the medium. If an error occurs while writing the data to the medium, and Good status has already been returned, a deferred error will be generated.

The Synchronize Cache command may be used to force the drive to write all cached write dat a to the med ium. Upon completion of a Synchronize Cache command, all data received from previous write commands will have been written to the medium.

Tables 19 through 22 show the mode default settings for these drives.

5.5.2 Prefetch op e r at io n

If the Prefetch feature is enabled, data in contiguous logical blocks on the disk immediately beyond that which was requested by a Read command are retrieved and stored in the buffer for immediate transfer from the buffer to the host on subsequent Read commands that request those logical blocks (this is true even if cache operation is disabled). Though the pr ef etch operation uses the buffer as a cache, finding the requested data in the buffer is a prefetch hit, not a cache operation hit.

To enable Prefetch, use Mode Select page 08h, byte 12, bit 5 (Disable Read Ahead - DRA bit). DRA bit = 0 enables prefetch.

The drive does not use the Max Prefetch field (bytes 8 and 9) or the Prefetch Ceiling field (bytes 10 and 11). When prefetch (read look-ahead) is enabled (enabled by DRA = 0), the drive enables prefetch of contiguous

blocks from the disk when it senses that a prefetch hit will likely occur. The drive disables prefetch when it decides that a prefetch hit is not likely to occur.

1. Error rate specified with automatic retries and data correction with ECC enabled and all flaws reallocated.

6.1 Error rates

The error rates stated in this manual assume the following:

• The drive is operated in accordance with this manual using DC power as defined in Section 7.3

• Errors caused by host system failures are excluded from error rate computations.

• Assume random data.

• Default OEM error recovery settings are applied. This includes AWRE, ARRE, full read retries, full write retries and full retry time.

6.1.1 Recoverable Errors

Recoverable errors are those detected and correcte d by the drive, and do not require user intervention. Recoverable Data errors will use Error Correction when needed. Recovered Data error rate is determined using read bits transferred for recoverab le errors occurring during a

read, and using write bits transferred for recoverable err ors occurring during a write.

6.1.2 Unrecoverable Errors

Unrecoverable Data Errors (Sense Key = 03h) are specified at less than 1 sector in error per 1016 bits transferred. Unrecoverable Data Errors resulting from the same cause are treated as 1 error for that block.

14 Savvio 10K.5 FC Product Manual, Rev. D

6.1.3 Seek errors

A seek error is defined as a failure of the drive to position the heads to the addressed track. After detecting an initial seek error, the drive automatically performs an error recovery process. If the error recovery process fails, a seek positioning error (Error code = 15h or 02h) will be reported with a Hardware error (04h) in the Sense Key. Recoverable seek errors are specified at Less than 10 errors in 10

seeks. Unrecoverable seek errors

(Sense Key = 04h) are classified as drive failures.

6.1.4 Interface errors

An interface error is defined as a failure of the receiver on a port to recover the data as transmitted by the device port connected to the receiver. The error may be detected as a running disparity error, illegal code, loss of word sync, or CRC error. The total error rate for a loop of devices is the sum of the individual device error rates.

6.2 Reliability and service

You can enhance the reliability of disk drives by ensuring that the drive receives adequate cooling. Section 7.0 provides temperature measurements and other information that may be used to enhance the service life of the drive. Section 9.2 provides recommended air-flow information.

6.2.1 Annualized Failure Rate (AFR) and Mean Time Between Failures (MTBF)

These drives shall achieve an AFR of 0.44% (MTBF o f 2,000,000 hours) when operat ed in an environment th at ensures the HDA case temperatures do not exceed the values specified in Section 7.5.1.

Operation at case temperatures outside the specifications in Section 7.5.1 may increase the AFR (dec rease the MTBF).

AFR and MTBF statistics are population statistics that are no t relevant to individual unit s. AFR and M TBF specifications are based on the following assumptions for Enterprise Storage System environments:

• 8,760 power-on hours per year

• 250 average on/off cycles per year

• Operating at nominal voltages

• System provides adequate cooling to ensure the case temperatures specified in Section 7.5.1 are not exceeded.

6.2.2 Preventive maintenance

No routine scheduled preventive maintenance is required.

6.2.3 Hot plugging the drive

Inserting and removing the drive on the FC-AL will interrupt loop operation. The interruption occurs when the receiver of the next device in the loop must synchronize to a different input signal. FC error detection mechanisms, character sync, running disparity, word sync, and CRC are able to detect any error. Recovery is initiated based on the type of error.

The disk drive defaults to the FC-AL Monitoring state, Pass-through state, when it is powered-on by switching the power or hot plugged. T he control line to an option al port bypass circuit (external to the drive), defaults to the Enable Bypass state. If the bypass circuit is present, the next device in the loop will continue to receive the output of the previous device to the newly inserted device. If the bypass circuit is not present, loop operation is temporarily disrupted until the next device starts receiving the output from the newly inserted device and regains synchronization to the new input.

Savvio 10K.5 FC Product Manual, Rev. D 15

The Pass-through state is disabled while the drive performs self test of the FC interface. The control line for an external port bypass circuit remains in the Enable Bypass state while self test is running. If the byp ass circuit is present, loop operation may continue. If the bypass circuit is not present, loop operation will be halted while the self test of the FC interface runs.

When the self test completes successfully, the control line to the bypass circuit is disabled and the drive enters the FC-AL Initializing state. The receiver on the next dev ice in the lo op must synchr onize to output of the newly inserted drive.

If the self-test fails, the control line to the bypass circuit remains in the Enable Bypass state.

Note. It is the responsibility of the systems integrator to assure that no temperature, energy , voltage hazard, or ESD poten-

tial hazard is presented during the hot connect/disconnect operation. Discharge the static electricity from the drive carrier prior to inserting it into the system.

Caution. The drive motor must come to a complete stop prior to changing the plane of operation. This time is

required to insure data integrity.

6.2.4 S.M.A.R.T.

S.M.A.R.T. is an acronym for Self-Monitoring Analysis and Reporting Technology. This technology is intended to recognize conditions that indicate imminent drive failure and is designed to provide sufficient warning of a failure to allow you to back up the data before an actual failure occurs.

Note. The drive’s firmware monitors specific attributes for degrada tion over time bu t can’t predict instantaneous drive fail-

ures.

Each monitored attribute has been selected to monitor a specific set of failure conditions in the operating performance of the drive and the thresholds are op tim ized to minimize “false” and “failed” predictions.

Controlling S.M.A.R.T.

The operating mode of S.M.A.R.T. is controlled by the DEXCPT and PERF bits on the Informational Exceptions Control mode page (1Ch). Use the DEXCPT bit to enable or disable the S.M.A.R.T. feat ure. Setting the DEXCPT bit disables all S.M.A.R.T. functions. When enabled, S.M.A.R.T. collects on-line data as the drive performs normal read and write operations. When the PERF bit is set, the drive is considered to be in “On-line Mode Only” and will not perform off-line functions.

You can measure off-line attributes and force the drive to save the data by using the Rezero Unit comma nd. Forcing S.M.A.R.T. resets the timer so that the next scheduled interrupt is in one hour.

You can interrogate the drive through the host to determine the time remaining before the ne xt scheduled measurement and data logging process occurs. To accomplish this, issue a Log Sense command to log page 0x3E. This allows you to control when S.M.A.R.T. interruptions occur. Forcing S.M.A.R.T. with the RTZ command resets the timer.

Performance impact

S.M.A.R.T. attribute data is saved to the disk so that the events that caused a pr edictive failure can be recreated. The drive measures and saves parameters once every hour subject to an idle period on the FC-AL bus. The process of measuring off-line attribute data and saving data to the disk is interruptable. The maximum online only processing delay is summarized below:

Reporting control

Reporting is controlled by the MRIE bits in the Informational Exceptions Control mode page (1Ch). Subject to the reporting method. For example, if the MRIE is set to one, the firmware will issue to the host an 01-5D00 sense code. The FRU field contains the type of predictive failure that occurred. The error code is preserved through bus resets and power cycles.

Determining rate

S.M.A.R.T. monitors the rate at which errors occur and signals a pr edictive fai lure if the rate of d egrad ed er rors increases to an unacceptable level. To determine rate, error events are logged and com pared to the number of total operations for a given attribute. The interval defines the number of opera tions o ver whic h to me asure the rate. The counter that keeps track of the current numbe r of operations is referred to as the Interval Counter.

S.M.A.R.T. measures error rates. All errors for each monitored attribute are recorded. A counter keeps track of the number of errors for the current interval. This counter is referred to as the Failure Counter.

Error rate is the number of errors per operation. The algor ithm that S.M .A.R.T. uses to record rates of error is to set thresholds for the number of errors and their interval. If the number of errors exceeds the threshold before the interval expires, the error rate is considered to be unacceptable. If the number of errors does not exceed the threshold before the interval expires, the error rate is considered to be acceptable. In either case, the interval and failure counters are reset and the process starts over.

Predictive failures

S.M.A.R.T. signals predictive failures when the drive is performing unacceptably for a period of time. The firmware keeps a running count of the number of times the error rate for each attribute is unacceptable. To accomplish this, a counter is incremented e ach time the erro r rate is unacceptable and decremented (not to exceed zero) whenever the error rate is acceptable. If the counter continually increments such that it reaches the predictive threshold, a predictive failure is signaled. This counter is referred to as the Failure History Counter. There is a separate Failure History Counter for each attribute.

6.2.5 Thermal monitor

Savvio 10K.5 FC drives implement a temperature warning system which:

1. Signals the host if the temperature exceeds a value which would threaten the drive.

2. Signals the host if the temperature exceeds a user-specified value.

3. Saves a S.M.A.R.T. data frame on the drive which exceeds the threatening temperature value.

A temperature sensor monitors the drive temperature and issues a warning over the interface when the temperature exceeds a set th reshold. The t emperature is measured a t power-up an d then at te n-minute inter vals after power-up.

The thermal monitor system generates a warning code of 01-0B01 when the temperature exceeds the specified limit in compliance with the SCSI standard. The drive temperature is reported in the FRU code field of mode sense data. You can use this information to determine if the warning is due to the temperature exceeding the drive threatening temperature or the user-specified temperature.

This feature is controlled by the Enable Warning (EWasc) bit, and the reporting mechanism is controlled b y the Method of Reporting Informational Exceptions field (MRIE) on the Informational Exceptions Control (IEC) mode page (1Ch).

The current algorithm implements two temperature trip points. The first trip point is set at 68°C which is the maximum temperature limit according to the drive specification. The second trip point is user-selectable using the Log Select command. The reference temperature parameter in the temperature log page (see Table 1) can

Savvio 10K.5 FC Product Manual, Rev. D 17

be used to set this trip point. The default value for this drive is 68°C, however, you can set it to any value in the range of 0 to 68°C. If you specify a temper ature greater than 68°C in this field, the temperature is rounded down to 68°C. A sense code is sent to the host to indicate the rounding of the parameter field.

6.2.6 Drive Self Test (DST)

Drive Self Test (DST) is a technology designed to recognize drive fault conditions that qualify the drive as a failed unit. DST validates the functionality of the drive at a system level.

There are two test coverage options implemented in DST:

1. Extended test

2. Short test The most thorough option is the extended test that performs various tests on the d riv e a nd sca ns ev er y lo gic al

block address (LBA) of the drive. The short test is time-restricted and limited in length—it does not scan the entire media surface, but does some fundamental tests and scans portions of the media.

If DST encounters an error during either of these tests, it reports a fault condition. If the drive fails the test, remove it from service and return it to Seagate for service.

6.2.6.1 DST failure definition

The drive will present a “diagnostic failed” condition through the self-tests results value of the diagnostic log page if a functional failure is encountered during DST. The channel and servo parameters are not modified to test the drive more stringently, and the number of retries are not reduced. All retries and recovery processes are enabled during the test. If data is recoverable, no failure condition will be reported regardless of the number of retries required to recover the data.

The following conditions are considered DST failure conditions:

• Seek error after retries are exhausted

• Track-follow error after retries are exhausted

• Read error after retries are exhausted

• Write error after retries are exhausted Recovered errors will not be reported as diagnostic failures.

6.2.6.2 Implementation

This section provides all of the information necessary to implement the DST function on this drive.

6.2.6.2.1 State of the drive prior to testing

The drive must be in a ready state before issuing the Send Diagnostic command. There are multiple reasons why a drive may not be ready, some of which are valid conditions, and not errors. For example, a drive may be in process of doing a format, or another DST. It is the responsibility of the host application to determine the “not ready” cause.

While not technically part of DST, a Not Ready condition also qualifies the drive to be returned to Seagate as a failed drive.

18 Savvio 10K.5 FC Product Manual, Rev. D

A Drive Not Ready condition is reported by the drive under the following conditions:

• Motor will not spin

• Motor will not lock to speed

• Servo will not lock on track

• Drive cannot read configuration tables from the disk

In these conditions, the drive responds to a Test Unit Ready command with an 02/04/00 or 02/04/03 code.

6.2.6.2.2 Invoking DST

To invoke DST, submit the Send Diagnostic command with the appropriate Function Code (001b for the short test or 010b for the extended test) in bytes 1, bits 5, 6, and 7.

6.2.6.2.3 Short and extended tests

DST has two testing options:

1. short

2. extended

These testing options are described in the following two subsections. Each test consists of three segments: an electrical test segment, a servo test segment, and a read/verify scan

segment.

Short test (Function Code: 001b)

The purpose of the short test is to provide a time-limited test that tests as much of the drive as possible within 120 seconds. The short test does not scan the entire media surface, but does some fundamental tests and scans portions of the media. A complete read/verify scan is not performed and only factual failures will report a fault condition. This option provides a quick confidence test of the drive.

Extended test (Function Code: 010b)

The objective of the extended test option is to empirically test critical drive componen ts. For example, the seek tests and on-track operations test the positioning mechanism. The read operation tests the read head element and the media surface. The write element is tested through read/write/read operations. The integrity of the media is checked through a read/verify scan of the media. Motor functionality is tested by default as a part of these tests.

The anticipated length of the Extended test is reported through the Control Mode page.

6.2.6.2.4 Log page entries

When the drive begins DST, it creates a new entry in the Self-test Results Log page. The new entry is created by inserting a new self-test parameter block at the b eginning of the se lf-test result s log par ameter section of the log page. Existing data will be moved to make room for the new parameter block. The drive reports 20 parameter blocks in the log page. If there are more than 20 parameter blocks, the least recent parameter block will be deleted. The new parameter block will be initialized as follows:

1. The Function Code field is set to the same value as sent in the DST command

2. The Self-Test Results Value field is set to Fh

3. The drive will store the log page to non-volatile memory

After a self-test is complete or has been aborted, the drive updates the Self-Test Results Value field in its SelfTest Results Log page in non-volatile memory. The host may use Log Sense to read the results from up to the last 20 self-tests performed by the drive. Th e se lf- te st r esults value is a 4-bit field that reports the results of the test. If the field is set to zero, the drive passed with no errors detected by the DST. If the field is not set to zero, the test failed for the reason reported in the field.

Savvio 10K.5 FC Product Manual, Rev. D 19

The drive will report the failure condition and LBA (if applicable) in the Self-test Results Log parameter. The Sense key, ASC, ASCQ, and FRU are used to report the failure condition.

6.2.6.2.5 Abort

There are several ways to abort a diagnostic. You can use a SCSI Bus Reset or a Bus Device Reset message to abort the diagnostic.

You can abort a DST executing in background mode by using the abort code in the DST Function Code field. This will cause a 01 (self-test aborted by the application client) code to appear in the self-test results values log. All other abort mechanisms will be reported as a 02 (self-test routine was interrupted by a reset condition).

6.2.7 Product warranty

Beginning on the date of shipment to the customer and continuing for the period specified in your purchase contract, Seagate warrants that each product (including components and subassemblies) that fails to function properly under normal use due to defect in materia ls or workman ship or due to n onconformance to the applicable specifications will be repaired or replaced, at Seagate’s option and at no charge to the customer , if returned by customer at customer’s expense to Seagate’s designated facility in accordance with Seagate’s warranty procedure. Seagate will pay for transporting the repair or replacement item to the customer. For more detailed warranty information, refer to the standard terms and conditions of purchase for Seagate products on your purchase documentation.

The remaining warranty for a particular drive can be determined by calling Seagate Customer Service at 1-800-468-3472. You can also determine remaining warranty using the Seagate web site (www.seagate.com). The drive serial number is required to determine remaining warranty information.

Shipping

When transporting or shipping a drive, use only a Seagate-approved container. Keep your original box. Seagate approved containers are easily identified by the Seagate Approved Package label. Shipping a drive in a non-approved container voids the drive warranty.

Seagate repair centers may refuse receipt of components improperly packaged or obviously damaged in transit. Contact your authorized Seagate distributor to purchase additional b oxes. Seagate recommends shipping by an air-ride carrier experienced in handling computer equipment.

Product repair and return information

Seagate customer service centers are the only facilities authorized to service Seagate drives. Seagate does not sanction any third-party repair facilities. Any unauthorized repair or tampering with the factory seal voids the warranty.

Storage

The maximum recommended storage period for the drive in a non-operational environment is 90 days. Drives should be stored in the original unopened Seagat e shipping packaging when ever possible. Once the drive is removed from the Seagate original packaging the recommended maximum period between drive operation cycles is 30 days. During any storage period the drive non-operational temperature, humidity, wet bulb, atmospheric conditions, shock, vibration, magnetic and electrical field specifications should be followed.

7.0 Physical/electrical specifications

This section provides information relating to the physical and electrical characteristics of the dr ive.

7.1 PowerChoiceTM power management

Drives using the load/unload architecture provide programmable power management to tailor systems for performance and greater energy efficiency.

The table below lists the supporte d PowerChoice mod es. The further you go down in the t abl e, the more power savings you get. For example, Idle_B mode results in greater power savings than Idle_A mode. Standby modes results in the greatest power savings.

PowerChoice modes

Mode Description

Idle_A Reduced electronics

Idle_B Heads unloaded. Disks spinning at full RPM

Idle_C Heads unloaded. Disks spinning at reduced RPM

Standby_Y Heads unloaded. Disks spinning at reduced RPM

Standby_Z Heads unloaded. Motor stopped (disks not spinning)

PowerChoice can be invoked using one of these two methods:

• Power Condition mode page method—Enable and initializ e the idle cond ition tim ers an d/or the standby con dition timers. The timer values are based on the values set in the Power Condition mode page.

• START STOP UNIT command method—Use the START ST

OP UNIT command (OPERATION CODE 1Bh).

This allows the host to directly transition the drive to any supported PowerChoice mode.

If both the Power Condition mode page and START ST

OP UNIT command methods are used, the START STOP UNIT command request takes precedence over the Power Conditio n mode p age power control and may disable the idle condition and standby condition timers. The REQUEST SENSE command reports the current PowerChoice state if active and also the method by which the drive entered the PowerChoice state.

When the drive receives a command, all power condition timers are suspended if they wer e enabled via the Power Condition mode page. Once all outstanding commands are processed, the power condition timers are reinitialized to the values defined in the Power Condition mode page.

Savvio 10K.5 FC Product Manual, Rev. D 21

7.1.1 PowerChoice reporting methods

PowerChoiceTM provides these reporting methods for tracking purposes:

Request Sense command reports

• Current power condition

General DC power requirement notes.

1. Minimum current loading for each supply voltage is not less than 1.2% of the ma ximum operating curren t shown.

2. The +5V and +12V supplies should employ separate ground returns.

3. Where power is provided to multiple drives from a common supply, careful consideration for individual drive power requirements should be noted. Where multiple units are powered on simultaneously, the peak starting current must be available to each device.

4. Parameters, other than spindle start, are measured after a 25-minute warm up.

5. No terminator power.

7.3.1 Conducted noise immunity

Noise is specified as a periodic and random distr ibution of fr equencies coverin g a defi ned freque ncy. Maximum allowed noise values given below are peak-to-peak measurements and apply at the drive po wer connector.

+5 V = 250 mV pp from 0 to 100 Hz to 20 MHz. +12 V = 450 mV pp from 100 Hz to 100 KHz.

250 mV pp from 100 KHz to 20 MHz. 150 mV pp from 20 MHz to 80 MHz.

7.5 Environmental limits

Temperature and humidity values experienced by the drive must be such that condensation does not occur on any drive part. Altitude and atmospheric pressure specifications are referenced to a standard day at 58.7°F (14.8°C). Maximum wet bulb temperature is 82°F (28°C).

To maintain optimal performance drives should be run at nominal case temperatures.

Note.

7.5.1 Temperature

a. Operating

The drive meets the operating specifications over a 41°F to 131°F (5°C to 55°C) drive case temperature r

ange with a maximum temperature gradient of 36°F (20°C) per hour.

The maximum allowable drive case temperature is 60°C.

The MTBF specification for the drive assumes the operat case temperature. The rated MTBF is based upon a sustained case temperature of 122°F (50°C). Occasional excursions in operating temperature between the rated MTBF temperature and the maximum drive

perating case temperature may occur without impact to the rated MTBF temperature. However continual or

o sustained operation at case temperatures beyond the rated MTBF temperature will degrade the drive MTBF and reduce product reliability.

Air flow may be required to achieve consistent nominal case temperature values (see Section 9.2). To confirm that the required cooling is provided for the electro configuration, and perform random write/read operations. After the temperatures stabilize, measure the case temperature of the drive.

b. Non-operating

–40° to 158°F (–40° to 70°C) package ambient with a maximum gradient of 36°F (20°C) per hour. This spe

cification assumes that the drive is packaged in th e shipping cont ainer designed b y Seagate for use with

7.5.4 Shock and vibration

Shock and vibration limits specified in this document are measured directly on the drive chassis. If the drive is installed in an enclosure to which the stated shock and/or vibration criteria is applied, resona nces may occur internally to the enclosure resulting in drive movement in excess of the stated limits. If this situation is apparent, it may be necessary to modify the enclosure to minimize drive movement.

The limits of shock and vibration defined within this document are specified with the drive mounted by any of the four methods shown in Figure 9, and in accordance with the restrictions of Section 9.4.

7.5.4.1 Shock

a. Operating—normal

The drive, as installed for normal operation, shall oper ate error free while subjected to intermittent shoc k not exceeding:

• 15 Gs at a duration of 11ms (half sinewave)

• 25 Gs at a duration of 2ms (half sinewave)

• 65 Gs at a duration of 2ms (half sinewave) when performing reads only

Shock may be applied in the X, Y, or Z axis. Shock is not to be repeated more than once every 2 seconds. b. Non-operating

The limits of non-operating shock shall apply to all conditions of handling and transportation. This includes both isolated drives and integrated drives.

The drive subjected to nonrepetitive shock not exceeding the three values below, shall not exhibit device

damage or performance degradation.

• 80 Gs at a duration of 11ms (half sinewave)

• 400 Gs at a duration of 2ms (half sinewave)

•300 Gs at a duration of 0.5ms (half sinewave)

Shock may be applied in the X, Y, or Z axis.

c. Packaged

Seagate finished drive bulk packs are designed and tested to meet or exceed applicable ISTA and ASTM standards. Volume finished drives will be shipped from Seagate factories on pallets to minimize freight costs and ease material handling. Seagate finished drive bulk packs may be shipped individually. For less than full shipments, instructions are printed on the bulk p ack carton for minimum drive quantities and proper drive placement.

7.5.4.2 Vibration

a. Operating—normal

The drive as installed for normal operation, shall comply with the complete specified performance while subjected to continuous vibration not exceeding

5-500 Hz @ 0.5 G (zero to peak) Vibration may be applied in the X, Y, or Z axis. Operating normal translational random flat profile 10 - 500 Hz (transactional random flat profile) 0.5 GRMS

b. Operating—abnormal

Equipment as installed for normal operation shall not incur physical damage while subjected to periodic vibration not exceeding:

15 minutes of duration at major resonant frequency 5-500 Hz @ 0.75 G (X, Y, or Z axis)

Vibration occurring at these levels may degrade operational performance during the abnormal vibration period. Specified operational performance will continue when normal operating vibration levels are resumed. This assumes system recovery routines are available.

Operating abnormal translational random flat profile 10 - 500 Hz (transactional random flat profile) 1.2 GRMS

c. Non-operating

The limits of non-operating vibration shall apply to all conditions of handling and transportation. This includes both isolated drives and integrated drives.

The drive shall not incur physical damage or degraded performance as a result of continuous vibration not exceeding

5-500 Hz @ 3.0 G (zero to peak) Vibration may be applied in the X, Y, or Z axis. Non-operating translational random flat profile 10 - 500 Hz (transactional random flat profile) 2.4 GRMS

7.5.5 Acoustics

Sound power during idle mode shall be 3.0 bels typical when measured to ISO 7779 specification. There will not be any discrete tones more than 10 dB above the masking noise on typical drives when mea-

sured according to Seagate specification 30553-001. There will not be any tones more than 24 dB above the masking noise on any drive.

7.5.6 Air cleanlines s

The drive is designed to operate in a typical office environment with minimal environmental control.

Savvio 10K.5 FC Product Manual, Rev. D 39

7.5.7 Corrosi v e en v iro nment

Seagate electronic drive components pass accelerated corrosion testing equivalent to 10 years exposure to light industrial environments containing sulfurous gases, chlorine and nitric oxide, classes G and H per ASTM B845. However, this accelerated testing cannot duplicate every potential application environment.

Users should use caution exposin g any electronic c omponents to uncontrolled chemical pollutants and corrosive chemicals as electronic drive component reliability can be affected by the installation environment. The silver, copper, nickel and gold films used in Seagate products are especially sensitive to the presence of sulfide, chloride, and nitrate contaminants. Sulfur is found to be th e most damaging . In addition, electro nic component s should never be exposed to condensing water on the surface of the printed circuit board assembly (PCBA) or exposed to an ambient relative humidity greater than 95%. Materials used in cabinet fabrication , such as vulcanized rubber, that can outgas corrosive compounds should be minimized or eliminated. The useful life of any electronic equipment may be extended by replacing materials near circuitry with sulfide-free alternatives.

8.0 Defect and error management

Seagate continues to use innovative technologies to manage defects and errors. These technologies are designed to increase data integrity, perform drive self-maintenance, and validate proper drive operation.

SCSI defect and error management involves drive internal defect/error manage ment and FC system er ror considerations (errors in communications between the initiator and the drive). In addition, Seagate provides the following technologies used to increase data integrity and drive reliability:

• Background Media Scan (see Section 8.4)

• Media Pre-Scan (see Section 8.5)

• Deferred Auto-Reallocation (see Section 8.6)

• Idle Read After Write (see Section 8.7) The read error rates and specified storage capacities are not dependent on host (initiator) defect management

routines.

8.1 Drive internal defects/errors

During the initial drive format operation at the factory, media defects are identified, tagged as being unusable, and their locations recorded on the drive primary defects list (referred to as the “P’ list and also as the ETF defect list). At factory format time, these known defects are also reallocated, that is, reassigned to a new place on the medium and the location liste d in the defects reallocation table. The “P” list is no t altered after factory formatting. Locations of defects found and reallocated during error recovery procedures after drive shipment are listed in the “G” list (defects growth list). The “P” and “G” lists may be referenced by the initiator us ing the Read Defect Data command.

Details of the SCSI commands supported by the drive are described in the Fibre Channel Interface Manual. Also, more information on the drive Error Recovery philosophy is presented in the Fibre Channel Interface Manual.

8.2 Drive error recovery procedures

When an error occurs during drive operation, the drive, if pr ogrammed to do so, performs e rror recover y procedures to attempt to recover the dat a . The error reco very procedur es used depend o n the options previously set in the Error Recovery Parameters mode page. Error recovery and defect management may involve using several SCSI commands described in the SCSI Interface Manual. The drive implemen ts selectable error r ecov ery time limits required in video applications.

The error recovery scheme supported by the drive provides a way to control the to tal error r ecovery time for the entire command in addition to controlling the recovery level for a single LBA. The total amount of time spent in error recovery for a command can be limited using the Recovery Time Limit bytes in the Error Recovery mode page. The total amount of time spent in error recovery for a single LBA can be limited using the Read Retry Count or Write Retry Count bytes in the Error Recovery mode page.

42 Savvio 10K.5 FC Product Manual, Rev. D

The drive firmware error recovery algorithms consist of 20 levels for read recoveries and five levels for write. Each level may consist of multiple steps, where a step is defined as a recovery function involving a single reread or re-write attempt. The maximum level used by the drive in LBA recovery is determined by the read and write retry counts.

Table 6 equates the read and write retry count with the maximum possible recovery time for read and write recovery of individual LBAs. The times given do not include time taken to perform reallocations. Reallocations are performed when the ARRE bit (for reads) or AWRE bit (for writes) is one, the RC bit is zero, and the recovery time limit for the command has not yet been met. Time needed to perform reallocation is not counted against the recovery time limit.

When the RC bit is one, reallocations are disabled even if the ARRE or AWRE bits are one. The drive will still perform data recovery actions within the limits defined by the Read Retry Count, Write Retry Count, and Recovery Time Limit parameters. However, the drive does not report any unrecovered errors.

Table 6: Read and write retry count maximum recovery times

* For read retry count, every tick ~ 5% of total error recovery. Valid range setting is 1-20. e.g. 1 ~ 5% 5 ~ 25% 20 ~ 100% Setting these retry counts to a value below the default setting could result in degradation of the unrecovered

error rate. For example, suppose the read/write recovery page has the RC bit = 0 and if the read retry count is set to 5, this means ~ 25% of error recovery will be executed which consumes 621.62 ms (please refer to the table above). If the limit is reached and a LBA has not yet been recovered (i.e. requires retries beyond 621.62 ms), the command will end with Check Condition status report and unrecoverable read error will be reported.

8.3 FC-AL system errors

Information on the reporting of operational errors or faults across the interface is given in the Fibre Channel Interface Manual. The FCP Response returns information to the host about numerous kinds of errors or faults.

The Receive Diagnostic Results reports the results of diagnostic operations performed by the drive. Status returned by the drive to the initiator is described in the Fibre Channel Interface Manual. Status reporting

plays a role in systems error management and its use in that respect is described in sections where the various commands are discussed.

Savvio 10K.5 FC Product Manual, Rev. D 43

8.4 Background Media Scan

Background Media Scan (BMS) is a self-initiated media scan. BMS is defined in the T10 document SPC-4 available from the T10 committee. BMS performs sequential reads across the entire pack of the media while the drive is idle. In RAID arrays, BMS allows hot spare drives to be scanned for defects prior to being put into service by the host system. On regular duty drives, if the host system makes use of the BMS Log Page, it can avoid placing data in suspect locations on the media. Unreadable and recovered error sites will be logged or reallocated per ARRE/AWRE settings.

With BMS, the host system can consume less power and system overhead by only checking BMS status and results rather than tying up the bus and consuming power in the process of host-i nitiated media scan ning activity.

Since the background scan functions are only done dur ing idle periods, BMS ca uses a negligible imp act to system performance. The first BMS scan for a newly manufactured drive is performed as quickly as possible to verify the media and protect data by setting the “Start time after idle” to 5ms, all subsequent scans begin after 500ms of idle time. Other features that normally use idle time to function will function normally because BMS functions for bursts of 800ms and then suspends activity for 100ms to allow other background functions to operate.

BMS interrupts immediately to service host commands from the interface bus while performing reads. BMS will complete any BMS-initiated error recovery prior to returning to service host-initiated commands. Overhead associated with a return to host-s ervicing activity from BMS only impacts the first command that interrupted BMS, this results in a typical delay of about 1ms.

8.5 Media Pre-Scan

Media Pre-Scan is a feature that allows the drive to repair media errors that would otherwise have been found by the host system during critical data accesses early in the drive’s life. The default setting for Media Pre-Scan is enabled on standard products. Media Pre-Scan checks each write command to determine if the destination LBAs have been scanned by BMS. If the LBAs have been verified, the drive proceeds with the normal write command. If the LBAs have not been verified by BMS, Pre-Scan will convert the write to a write verify to certify that the data was properly written to the disk.

Note. During Pre-Scan write verify commands, write performance may decrease by 50% u ntil Pre-Scan completes. Write

performance testing should be performed after Pre-Scan is complete. This may be checked by reading the BMS status.

To expedite the scan of the full pack and subsequently exit from the Pre-Scan period, BMS will begin scanning immediately when the drive goes to idle during the Pre-Scan period. In the event that the drive is in a high transaction traffic environment and is unable to complete a BMS scan within 24 power on hours BMS will disable Pre-Scan to restore full performance to the system.

8.6 Deferred Auto-Reallocation

Deferred Auto-Reallocation (DAR) simplifies reallocation algorithms at the system level by allowing the drive to reallocate unreadable locations on a subsequent write command. Sites are marked for DAR during read operations performed by the drive. When a write command is received for an LBA marked for DAR, the auto-reallocation process is invoked and attempts to rewrite the data to the original location. If a verification of this rewrite fails, the sector is re-mapped to a spare location.

This is in contrast to the system having to use the Reassign Command to reassign a location that was unreadable and then generate a write command to rewrite the data. DAR is most effective when AWRE and ARRE are enabled—this is the default setting from the Seagate factory. With AWRE and ARRE disabled DAR is unable to reallocate the failing location and will report an error sense code indicating that a write command is being attempted to a previously failing location.

44 Savvio 10K.5 FC Product Manual, Rev. D

8.7 Idle Read After Write

Idle Read After Write (IRAW) utilizes idle time to verify the integrity of recently written data. During idle periods, no active system requests, the drive reads recently written data from the media and compares it to valid write command data resident in the drives data buffer. Any se ctor s that fail th e comparison result in the invocation of a rewrite and auto-reallocation process. Th e process attempts to rewrite the data to the original location . If a verification of this rewrite fails, the sector is re-mapped to a spare location.

8.8 Protection Information (PI)

Protection Information is intended as a standardized approach to system level LRC traditionally provided by systems using 520 byte formatted LBAs. Drives formatted with PI information provide the same, common LBA count (i.e. same capacity point) as non-PI formatted drives. Sequential performance of a PI drive will be reduced by approximately 1.56% due to the extra overhead of PI being transferred from the media that is not calculated as part of the data transferred to the host. To determine the full transfer rate of a PI dr ive, transfer s should be calculated by adding the 8 extra bytes of PI to the transferred LBA length, i.e. 512 + 8 = 520. PI formatted drives are physically formatted to 520 byte sectors that store 512 bytes of customer data with 8 bytes of Protection Information appended to it. The advantage of PI is that the Protection Information bits can be managed at the HBA and HBA driver level. Allowing a system that typically does not support 520 LBA formats to integrate this level of protection.

Protection Information is valid with any supported LBA size. 512 LBA size is used here as common example.

8.8.1 Levels of PI

There are 4 types of Protection Information. Type 0 - Describes a drive that is not formatted with PI information bytes. This allows for legacy support in non-

PI systems. Type 1 - Provides support of PI protection using 10 and 16 byte commands. The RDPROTECT and WR TPRO-

TECT bits allow for checking control through the CDB. Eight bytes of Protection Information are transmitted at LBA boundaries across the interface if RDPROTECT and WRTPROTECT bits are nonzero values. Type 1 does not allow the use of 32 byte commands.

Type 2 - Provides checking control and additional expected fields within the 32 byte CDBs. Eight bytes of Protection Information are transmitted at LBA boundaries across the interface if R DPROTECT and WRTPROTECT bits are nonzero values. Type 2 does allow the use of 10 and 16 byte commands with zer o values in the RDPROTECT and WRTPROTECT fields. The drive will generate 8 bytes (e.g.0xFFFF) 8 bytes of Protection Information to be stored on the media, but the 8 bytes will not be transferred to the host during a read command.

Type 3 - Seagate products do not support Type 3.

8.8.2 Setting and determining the current Type Level

A drive is initialized to a type of PI by using the format command on a PI capable dri ve . Once a drive is formatted to a PI Type, it may be queried by a Read Capacity (16) command to report the PI type which it is currently formatted to. PI T ypes cannot coexist on a sing le drive. A drive can only be formatted to a single PI Type. It can be changed at anytime to a new Type but requires a low level format which destroys all existing data on the drive. No other vehicle for changing the PI type is provided by the T10 SBC3 specification.

Type 1 PI format CDB command: 04 90 00 00 00 00, Write Buffer: 00 A0 00 00 Type 2 PI format CDB command: 04 D0 00 00 00 00, Write Buffer: 00 A0 00 00

9.0 Installation

Savvio 10K.5 FC disk drive installation is a plug-and-play pr ocess. There ar e no jum pers, switches, or te rminators on the drive. Simply plug the drive into the host’s 40-pin Fibre Channel backpanel connector (FC-SCA) no cables are required. See Section 10.5 for additional information about this connector.

Use the FC-AL interface to select drive ID and all option configurations for devices on the loop. If multiple devices are on the same FC-AL and physical addresses are used, set the device selection IDs (SEL

IDs) on the backpanel so that no two devices have the same selection ID. This is called the har d assigned arbitrated loop physical address (AL_PA). There are 125 AL_PAs available (see Table 28). If you set the AL_PA on the backpanel to any value other than 0, the device plugged into the backpanel’s SCA connector inherits this AL_PA. In the event you don’t successfully assign unique hard addresses (and therefore have duplicate selection IDs assigned to two or more devices), the FC-AL generates a message indicating this condition. If you set the AL_PA on the backpanel to a value of 0, the system issues a unique soft-assigned physical address automatically.

Loop initialization is the process used to verify or obtain an address. The loop initialization process is performed when power is applied to the drive, when a device is added or removed from the Fibre Ch annel loop , or when a device times out attempting to win arbitration.

• Set all option selections in the connector prior to applying power to the drive. If you change options after applying power to the drive, recycle the drive power to activate the new settings.

• It is not necessary to low-level format this drive. The drive is shipped from the factory low-level formatted in 512-byte logical blocks. Y ou need to reformat the drive only if you want to select a different logical block size.

9.1 Drive ID/option selection

All drive options are made through the interface connector (J1). Table 25 provides the pin descriptions for the 40-pin Fibre Channel single connector (J1).

9.2 Drive orientation

The drive may be mounted in any orientation. All drive performance characterizations, however, have been done with the drive in horizontal (disks level) and vertical (drive on its side) orientations, which are the two preferred mounting orientations.

9.3 Cooling

The host enclosure must dissipate heat from the drive. You sh ou ld co nfirm that the host enclosure is designed to ensure that the drive operates within the temperatur e measurement guidelines described in Section 7.5.1. In some cases, forced airflow may be required to keep temperatures at or below the temperatures specified in Section 7.5.1.

Savvio 10K.5 FC Product Manual, Rev. D 47

If forced air is necessary , possib le air-flow patterns ar e shown in Figure 11. The air-flow patterns are created by fans either forcing or drawing air as shown in the illustrations. Conduction, convection, or other forced air-flow patterns are acceptable as long as the temperature measurement guidelines of Section 7.5.1 are met.

9.4 Drive mounting

Mount the drive using the bottom or side mounting holes . If you mount the drive using the bottom holes, e nsure that you do not physically distort the drive by attempting to mount it on a stiff, non-flat surface.

The allowable mounting surface stiffness is 80 lb/in (14.0 N/mm) . The followin g equation and paragraph define the allowable mounting surface stiffness:

K x X = F < 15lb = 67N

where K is the mounting surface stiffness (units in lb/in or N/mm) and X is the out-of-plane surface distortion (units in inches or millimeters). The out-of-plane distortion (X) is determined by defining a plane with three of the four mounting points fixed and evaluating the out-of-plane deflection of the fourth mounting point when a known force (F) is applied to the fourth point.

Note. Before mounting the drive in any kind of 3.5-inch to 5.25-inch adapter frame, verify with Seagate Technology that the

drive can meet the shock and vibration specifications given herein while mounted in such an adapter frame. Adapter frames that are available may not have a mechanical structure capable of mounting the drive so that it can meet the shock and vibration specifications listed in this manual.

48 Savvio 10K.5 FC Product Manual, Rev. D

9.5 Grounding

Signal ground (PCBA) and HDA ground are connected together in the drive and cannot be separated by the user. The equipment in which the drive is mounted is connected directly to the HDA and PCBA with no electrically isolating shock mounts. If it is desired for the system chassis to not be connected to the HDA/PCBA ground, the systems integrator or user must provide a nonconductive (electrically isolating) method of mounting the drive in the host equipment.

Increased radiated emissions may result if you do not provide the maximum surface area ground connection between system ground and drive ground. This is the system designer’s and integrator’s responsibility.

10.2 Dual port support

Savvio 10K.5 FC drives have two independent FC-AL ports. These ports may be connected on independent loops or on the same loop. Port A and Port B may be connected in any order or combination.

• If both ports are connected on independent lo op s and har d addressing is used, the d rive interface addre ss is selected through the interface connector, both ports will seek the same loop address. If no conflict, both ports will have the same loop address.

• If both ports are connected in the same loop and hard addressing is used, at least one port will attempt taking a soft address to prevent an address conflict.

Subject to buffer availability, the Savvio 10K.5 FC drives support:

• Concurrent port transfers—The drive supports receiving transfers on both ports at the same time when the ports are on independent loops.

• Full duplex—The drive supports sending FCP_Data, FCP_RSP, FCP_XFR_RDY and ELS transfers while receiving frames on both ports.

10.3.2 Mode Sense data

The Mode Sense command provides a way for the drive to report its operating parameters to the initiator. The drive maintains four sets of mode parameters:

1. Default values

Default values are hard-coded in the drive firmware stored in flash E-PROM (nonvolatile memory) on the drive’s PCB. These default values can be changed only by downloading a complete set of new firmware into the flash E-PROM. An initiator can request and receive from the drive a list of default values and use those in a Mode Select command to set up new current and saved values, where the values are change able.

2. Saved values

Saved values are stored on the drive’s media using a Mode Select command. Only parameter values that are allowed to be changed can be changed by this method. Parameters in the saved values list that are not changeable by the Mode Select command get their values from default values storage.

When power is applied to the drive, it takes saved values from the media and stores them as current values in volatile memory. It is not possible to change the current values (or the saved values) with a Mode Select command before the drive achieves operating speed and is “r ead y.” An attempt to do so results in a “Check Condition” status.

Savvio 10K.5 FC Product Manual, Rev. D 61

On drives requiring unique saved values, the required unique saved values are stored into the saved values storage location on the media prior to shipping the drive. Some drives may have unique firmware with unique default values also.

On standard OEM drives, the saved values are taken from the default values list and stored into the saved values storage location on the media prior to shipping.

3. Current values Current values are volatile values being used by the drive to control its operation. A Mode Select command

can be used to change the values identified as changeable values. Originally, current values are installed from saved or default values after a power on reset, hard reset, or Bus Device Reset message.

4. Changeable values Changeable values form a bit mask, stored in nonvolatile memory, that dictates which of the current values

and saved values can be changed by a Mode Select command. A one (1) indicates the value can be changed. A zero (0) indicates the value is not changeable. For example, in Table

20, refer to Mode page

81, in the row entitled “CHG.” These are hex numbers representing the changeable values for Mode page

81. Note in columns 5 and 6 (bytes 04 and 05), there is 00h which indicates that in bytes 04 and 05 none of the bits are changeable. Note also that bytes 06, 07, 09, 10, and 11 are not changeable, because those fields are all zeros. In byte 02, hex value FF equates to the binary pattern 11111111. If there is a zero in any bit position in the field, it means t hat bit is not changeable. Since all of the bits in byte 02 are ones, all of these bits are changeable.

The changeable values list can only be changed by downloading new firmware into the flash E-PROM.

Note. Because there are often several different versions of drive control firmware in the total population of dri ves in the

field, the Mode Sense values given in the following tables may not exactly match those of some drives.

The following tables list the values of the data bytes returned by the d rive in response to the Mode Sense command pages for SCSI implementation (see the Fibre Channel Interface Manual ).

Definitions: DEF = Default value. Standard OEM drives are shipped configured this way.

CHG = Changeable bits; indicates if default value is changeable.

10.5 FC-AL physical interface

Figure 12 shows the location of the J1 Fibre Channel single connection attachment (FC-SCA). Figure 14 provides the dimensions of the FC-SCA connector.

Details of the physical, electrical, and logical characteristics are provided within this section. The operational aspects of Seagate’s Fibre Channel drives are provided in the Fibre Channel Interface Manual.

Figure 12. Physical interface

Note. Image of the HDA may not represent actual product, for reference only.

10.5.1 Physical characteristics

This section defines physical interface connector.

10.5.1.1 Physical description

FIbre Channel drives may be connected in a loop together or with other compatible FC-AL devices. A maximum of 127 devices may have addresses; however, one of the addresses is reserved for a fabric port switch device. This means 126 addresses are available for FC-AL devices. More FC-AL compatible devices may physically reside on the loop, but they will not be functional because they would not be able to obtain valid addresses.

Port bypass circuits (PBCs) allow devices to be inserted into unpopulated locations or removed from the loop with loop operation recovery after a brief interruption. These PBCs are located external to the FC-AL device. Figure 13 shows the relationship between the PBC and FC-AL device.

Signal type

*Short pins in mating backpanel connector. [1] This pin may be connected to external logic to detect the

presence of the drive. The drive connects this

pin to the common ground.

[2] Pins 9, 10, 17, 18, and 39 are option select pins and are tie

d high by the drive circuitry. The preferred electrical connection at the backplane is either open or grounded (open for the ‘1’ setting, grounded for the ‘0’ setting)

. Alternatively, these pins may be driven by a 3.3V logic device, pulled up to 3.3V through a pull-u p

resistor (recommended size of 10K ohm), or grounded through some other means.

10.5.6 Power

Power is supplied through the FC-SCA with support for +5 volts and +12 volts. All of the voltage pins in the drive connector are the same length.

Four 12 volt pins provide +12 volt power to the drive. The current return for the +12 volt power supply is through the common ground pins. The supply current and return current must be distributed as evenly as possible among the pins. The maximum current typically occurs while the drive motor is starting.

Three 5 volt pins provide logic power to the drive. The current retur n for the +5 volt power su pply is through the common ground pins. Distribute supply and return current as evenly as possible among the voltage and ground pins.

The mating connector pins use shorter contacts to achieve power surge reductions and to aid in “hot plugging” the drives. There are longer voltage contacts in the connector to enable the drive filter capacitors to charge. Current to the drive through the long charge pins is limited by the system in which the drive operates. Three of the +12 volt pins are shorter to allow capacitive p re-char ging through the longer +12 vo lt charge pin. Two of the +5 volt pins are shorter to allow capacitive precharging through the longer +5 volt charge pin.

10.5.7 Fault LED Out

The Fault LED Out signal is driven by the drive when:

• the drive detects failure of both ports

• the drive detects an internal failure

• the drive receives the appropriate fault LED command from the host The Fault LED Out signal is designed to pull down the cathode of a n L ED. The anode is a t tached to the proper

+5 volt supply through an appropriate current-limiting resistor. The LED and the current-limiting resistor are external to the drive.

Savvio 10K.5 FC Product Manual, Rev. D 71

10.5.8 Active LED Out

The Active LED Out signal is driven by the drive as indicated in Table 26.

Table 26: Active LED Out condition s

Normal command activity LED status

Spun down and no activity Slow blink (20% on and 80% off a 2 sec cycle) Spun down and activity (command executing) On Spun up and no activity On Spun up and activity (command executing) Off Spinning up or down Blinks steadily (50% on and 50% off) Format in progress Toggles on/off Write Same command in progress Toggles on/off

The Active LED Out signal is designed to pull down the cathode of an LED. The anode is attached to the proper +5 volt supply through an appropriate current limiting resistor. The LED and th e curr ent limi ting resis tor are external to the drive.

10.5.9 Enable port bypass signals

The – Enable Bypass Port A (– EN BYP Port A) and – Enable Bypass Port B (– EN BYP Port B) signals control the port bypass circuits (PBC) located external to the disk drive. The PBC allows a loop to remain functional in the event of a drive failure or removal. When these signals are active, low, the PBC bypasses the drive on the associated port. When an Enable Bypass signal is active, the corresponding Port Bypass LED signal in connector J1 is driven low by the disk drive. A pull down resistor, 1K, located with the PBC should be used to insure the bypass is enabled if the disk drive is not installed.

Failure modes detected by the disk drive that will enable bypass include:

• Transmitter/receiver wrap test failure

• Loss of receive clock

• Loss of transmission clock

• Drive interface hardware error

10.5.10 Motor start controls

The drive’s motor is started according to the Start_1 and Start_2 signals described in Table 27. The state of these signals can be wired into the backplane socket or driven by logic on the backplane.

Table 27: Motor start control signals

Case Start_2 Start_1 Motor spin function

1 Low Low M otor spins up at DC power on. 2 High Low Motor spins up only when SCSI Start command is received. 3 Low High Motor spins up after a delay of 12 seconds times the modulo 8 value

of the numeric SEL ID of the drive from DC power on.

4 High High The drive will not spin up.

72 Savvio 10K.5 FC Product Manual, Rev. D

10.5.11 SEL_6 through SEL_0 ID lines

The SEL_6 through SEL_0 ID lines determine drive address, and, optionally, for an Enclosure Services Interface. When the Parallel ESI line is high, the enclosure backp ane l must pro vide add ress info rmation on the SEL line. Refer to table 28 for a mapping of SEL to FC-AL physical addresses (AL_PA). You can think of the SEL lines as the equivalent of a backpanel logic plug. The drives does not provide pull up resistors on these lines. The backpanel is required to provide high and low inputs to the SEL_ID lines per the specifications in table 30 on page 75.

Note. Table 28 gives AL_PA values for each SEL value. The first entry in the table is SEL_ID 00. The last entry is SEL_ID

7D. SEL_ID 7E is AL_PA 00 which is not valid for an NL_Port, so is not included in the table. Also, SEL_ID 7Fh does map to a valid AL_PA; however, this value signals the drive that physical addresses are not b eing assigned using the SEL lines and that a “soft” address will be determined by FC-AL loop initialization.

When the Parallel ESI line is low, the enclosure backpanel logic switches to ESI mode if supported. There are two modes of ESI, seven bits of enclosure status and a bidirectional mode. ESI support and the mode are determined by the drive using a discovery pr ocess. Re fer to the Fibre Ch annel Inter face Ma nual for a de scription of ESI operation.

10.5.11.1 Parallel Enclosure Services Interface (ESI)

The parallel ESI line is an output from the drive. This line provides the enclosure with an indication of the present function of the SEL lines. A high level, the default state, indicates the d rive re quires a ddress infor mation o n the SEL lines. A low level indicates the drive is attempting an ESI transfer. The enclosure may not support ESI on any or all drive locations. It may only support the address function. Support of ESI is discovered by the drive. Refer to the Fibre Channel Interface Manual for a description of ESI operations.
