2.0 Applicable standards and reference documentation

The drive has been developed as a system peripheral to the highest standards of design and construction. The drive depends upon its host equipment to provide adequate power and environment in order to achieve optimum performance and compliance with applicable industry and governmental regulations. Special attention must be given in the areas of safety, power distribution, shielding, audible noise control, and temperature regulation. In particular, the drive must be securely mounted in order to guarantee the specified performance characteristics. Mounting by bottom holes must meet the requirements of Section 9.4.

2.1 Standards

The Cheetah 15K.7 FC family complies with Seagate standards as noted in the appropriate sections of this manual and the Seagate Fibre Channel Interface Manual, part number 100293070.

The drives are recognized in accordance with UL 60950-1 and CSA 60950-1 as tested by UL and EN60950-1 as tested by TUV.

The security features of Cheetah 15K.7 FC SED models are based on the “TCG Storage Architecture Core Specification” and the “TCG Storage Workgroup Security Subsystem Classs: Enterprise_A” specification with additional vendor-unique features as noted in this product manual.

2.1.1 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. As such, 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 enc losure does no t provide adequate shielding. If the I/O cables are external to the enclosure, shielded cables should be used, with the shields grounded to the enclosure and to the host controller.

2.1.1.1 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 Table 2, DC power requirements.

3.0 General description

Cheetah 15K.7 FC drives provide high performance, high capacity data storage for a variety of systems including engineering workstations, network servers, mainframes, and supercomputers. Cheetah 15K.7 FC drives support 4-Gbit Fibre Channel.

Cheetah 15K.7 FC drives support the Fibr e 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. Cheetah 15K.7 FC drives are classified as intelligent peripherals and provide level 2 conformance (highest level) with the ANSI SCSI-1 standard.

Cheetah 15K.7 FC SED models have provisions for “Security of Data at Rest” based on the standards defined by the Trusted Computing Group (see www.trustedcomputinggroup.org).

Note. Never disassemble the HDA and do not attempt to service items in the sealed enclosure (heads,

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.

Cheetah 15K.7 FC drives use a dedicated landing zone at the innermost 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 landing zone when power is removed from the drive.

An automatic shipping lock prevents potential damage to the heads and discs 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.

3.5 Formatted capacities

Standard OEM models are formatted to 512 bytes per block. The block size is selectable at format time and must be one of the supported sizes listed in the table below.

Seagate designs specify capacity points at certain block sizes that Seagate guarantees current and future products will meet. We recommend customers use this capacity in their project planning, as it ensures a stable operating point with backward and forward compatibility from generation to generation. The current guaranteed operating points for this product are:

Decimal Hex Decimal Hex Decimal Hex

Seagate drives also may be used at the maximum available capacity at a given block size, but the excess capacity above the guaranteed level will vary between other drive families and from generation to generation, depending on how each block size actually formats out for zone frequencies and splits over servo bursts. This added capacity potential may range from 0.1 to 1.3 percent above the guaranteed capacities listed above. Using the drives in this manner gives the absolute maximum capacity potential, but the user must determine if

ST3450857FC ST3450757FC

ST3300657FC ST3300557FC

Cheetah 15K.7 FC Product Manual, Rev. B 7

the extra capacity potential is useful, or whether their assurance of backward and forward compatibility takes precedence.

3.5.1 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.

3.6 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.

3.7 User-installed accessories

The following accessories are available. All kits may be installed in the field.

• Evaluation kit, part number 73473641. This kit provides an adapter card (“T-card”) to allow cable connections for two FC ports and DC power.

4.3 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 pr ocedure an d 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.

4.4 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 4.5.1 and 4.5.2.

All default cache and prefetch mode parameter values (Mode Page 08h) for standard OEM versions of this drive family are given in Table 18.

10 Cheetah 15K.7 FC Product Manual, Rev. B

4.5 Cache operation

Note. Refer to the Fibre Channel Interface Manual for more detail concerning the cache bits. Of the 16 Mbytes physical buffer space in the drive, approximately 13,000 kbytes can be used as a cache. The

buffer is divided into logical segments from which data is read and to which data is written. 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 possible, before any disc access is initiated. If cache operation is not enabled, the buffer is still used, but only as circular buffer segments during disc 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 (disco nnect/reconn ect contro l) 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 disc and transfers them into a segment, 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 4.5.2 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 specification 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.

4.5.1 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.

Cheetah 15K.7 FC Product Manual, Rev. B 11

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

Table 18 shows the mode default settings for the drive.

4.5.2 Prefetch operation

If the Prefetch feature is enabled, data in contiguous logical blocks on the disc 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 disc 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.

5.1 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 paragraph 6.2, "DC

power requirements."

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

• Assume random data.

5.1.1 Recoverable Errors

Recovereable errors are those detected and corrected by the drive, and do not require user intervention. Recoverable Data errors use retries and correction. Application of ECC on-the-fly correction alone is not con-

sidered a Recovered Data error. 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 errors occurring during a write.

5.1.2 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.

Cheetah 15K.7 FC Product Manual, Rev. B 13

5.1.3 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 erro rs in 10

seeks. Unrecoverable seek errors

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

5.1.4 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.

5.2 Reliability and service

You can enhance the reliability of Cheetah 15K.6 disc drives by ensuring that the drive receives adequate cooling. Section 6.0 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.

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

These drives shall achieve an AFR of 0. 55% (MTBF of 1,600,000 hours) when operated in an environment that ensures the HDA case temperatures do not exceed the values specified in Section 6.4.1.

Operation at case temperatures outside the specifications in Section 6.4.1 may increase the AF R (decrease the MTBF). AFR and MTBF statistics are poplulation statistics that are not relevant to individual units.

AFR and MTBF 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 6.4.1 are not exceeded.

5.2.2 Preventive maintenance

No routine scheduled preventive maintenance is required.

5.2.3 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 disc drive defaults to the FC-AL Monitoring state, Pass-through state, when it is powered-on by switching the power or hot plugged. The control line to an optional 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.

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

14 Cheetah 15K.7 FC Product Manual, Rev. B

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 haz-

ard, or ESD potential 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.

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 degrad ation over time but can’t predict inst ant a-

neous drive failures.

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 optimized 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. feature. 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 command. Forcing S.M.A.R.T. resets the timer so that the next scheduled interrupt is in two hours.

You can interrogate the drive through the host to dete rmine the time rema ining before the next sch eduled 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 disc so that the events that caused a predict ive failure can be recreated. The drive measures and saves parameters once every two hours subject to an idle period on the FC-AL bus. The process of measuring off-line attribu te data and saving data to the disc is un interruptable. The m aximum on-line only processing delay is summarized below:

Maximum processing delay

On-line only delay DEXCPT = 0, PERF = 1

Fully-enabled delay DEXCPT = 0, PERF = 0

S.M.A.R.T. delay times

42 milliseconds

163 milliseconds

Reporting control

Reporting is controlled by the MRIE bits in the Informational Exceptions Control mode page (1Ch). Subject to the reporting method, the firmware will issue to the host an 01-5Dxx sense code. The error code is preserved through bus resets and power cycles.

Cheetah 15K.7 FC Product Manual, Rev. B 15

Determining rate

S.M.A.R.T. monitors the rate at which erro rs occur and sig nals a pred ictive fa ilure if the ra te of deg raded 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 operations o ver whic h to m easur e the rate. The counter that keeps track of the current number 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 algori thm 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.

5.2.5 Thermal monitor

Cheetah 15K.7 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 interv als 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 repor ting mecha nism is controlle d by the Method of Reporting Informational Exceptions field (MRIE) on the Informational Exceptions Control (IEC) mode page (1Ch).

The current algorithm implem ents 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 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.

5.2.6 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 drive and scans 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.

5.2.6.1 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.

5.2.6.2 Implementation

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

5.2.6.2.1 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.

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

5.2.6.2.2 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.

Cheetah 15K.7 FC Product Manual, Rev. B 17

5.2.6.2.3 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/ve rify s can

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.

5.2.6.2.4 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 self- test result s log parame ter 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.

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.

5.2.6.2.5 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).

6.0 Physical/electrical specifications

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

6.1 AC power requirements

None.

6.2 DC power requirements

The voltage and current requirements for a single drive are shown below. Values indicated apply at the drive connector. Notes are shown following the last power requirements table.

The standard drive models and the SED drive models have identical hardware, however the security and encryption portion of the drive controller ASIC is enabled and functional in the SED models. This represents a small additional drain on the 5V supply of about 30mA and a commensurate increase of about 150mW in power consumption. There is no additional drain on the 12V supply.

three-quarters to maximum track.

General DC power requirement notes.

1. Minimum current loading for each supply voltage is not less than 1. 2% of the maximum opera ting current 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 10-minute warm up.

5. No terminator power.

22 Cheetah 15K.7 FC Product Manual, Rev. B

6.2.1 Conducted noise immunity

Noise is specified as a periodic and random distribution of frequencies covering a band from DC to 10 MHz. Maximum allowed noise values given below are peak-to-peak measurements and apply at the drive power connector.

+5 V = 250 mV pp from 0 to 100 kHz to 20 MHz. +12 V = 800 mV pp from 100 Hz to 8 KHz.

450 mV pp from 8 KHz to 20 KHz. 250 mV pp from 20 KHz to 5 MHz.

6.2.2 Power sequencing

The drive does not require power sequencing. The drive protects against inadvertent writing during power-up and down.

6.2.3 Current profiles

The +12V and +5V current profiles are shown in the following figures.

Note: All times and currents are typical. See Section 6.2 for maximum current requirements.

6.4 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).

6.4.1 Temperature

a. Operating

The maximum allowable continuous or sustained HDA case temperature for the rated Annualized Failure Rate (AFR) is 122°F (50°C) The maximum allowable HDA case temperature is 60°C. Occasional excur sions of HDA case temperatures above 122°F (50°C) or below 41°F (5°C) may occur without impact to the specified AFR. Continual or sustained operation at HDA case temperatures outside these limits may degrade AFR.

Provided the HDA case temperatures limits are met, the drive meets all specifications over a 41°F to 131°F (5°C to 55°C) drive ambient temperature range with a maximum temperature gradient of 86°F (30°C) per hour. Air flow m ay be needed in the dr ive enclosure to keep within this range (see Section 8.3). Operation at HDA case temperatures outside this range may adversely affect the drives ability to meet specifications. To confirm that the required cooling for the electronics and HDA case is provided, place the drive in its final mechanical configuration, perform random write/read operations and measure the HDA case temperature after it has stabilized.

6.4.4 Shock and vibration

Shock and vibration limits specified in th

is document are measured direc tly 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 8, and in accordance with the restric tions of Section 9.4. Orientation of the side nearest the I/O connector may be up or down.

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

6.4.7 Corrosive environment

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 vulca-

32 Cheetah 15K.7 FC Product Manual, Rev. B

nized 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.

6.4.8 RoHS compliance statement

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 Seagat e products are procured from external suppliers. We rely on the representations of our suppliers regarding the presence of RoHS sub stances in these parts and materials. Our supplier contracts require compliance with our che mical 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 disc drives documented in this publication. Current supplier declarations include disclosure of the inclusion of any RoHS-regulated substance in such parts or materials.

7.0 About self-encrypting drives

Self-encrypting drives (SEDs) offer encryption and security services for the protection of stored data, commonly known as “protection of data at rest.” These drives are compliant with the Trusted Computing Group (TCG) Enterprise Storage Specifications as detailed in Section 2.3.

The Trusted Computing Group (TCG) is an organization sponsored and operated by companies in the computer, storage and digital communications industry. Seagate’s SED models comply with the standards published by the TCG.

To use the security features in the drive, the host must be capable of constructing and issuing the following two SCSI commands:

• Security Protocol Out

• Security Protocol In These commands are used to convey the TCG protocol to and from the drive in their command payloads.

7.1 Data encryption

Encrypting drives use one inline encryption engine fo r each port, employing AES- 128 dat a encr yption in Cipher Block Chaining (CBC) mode to encrypt all data prior to being written on the media and to decrypt all data as it is read from the media. The encryption engines are always in operation, ca nnot be disab led, and do not detract in any way from the performance of the drive.

The 32-byte Data Encryption Key (DEK) is a random number which is genera ted by th e drive, n ever leaves the drive, and is inaccessible to the host system. The DEK is itself encrypted when it is stored on the media and when it is in volatile temporary storage (DRAM) external to the encryption engine. A unique data encryption key is used for each of the drive's possible16 data bands (see Section 7.5).

7.2 Controlled access

The drive has two security partitions (SPs) called the "Admin SP" and the "Locking SP." These act as gatekeepers to the drive security services. Security-related commands will not be accepted unless they also supply the correct credentials to prove the requester is authorized to perform the command.

7.2.1 Admin SP

The Admin SP allows the drive's owner to enable or disable firmware download operations (see Section 7.4). Access to the Admin SP is available using the SID (Secure ID) password or the MSID (Makers Secure ID) password.

Cheetah 15K.7 FC Product Manual, Rev. B 35

7.2.2 Locking SP

The Locking SP controls read/write access to the media and the cryptographic erase feature. Access to the Locking SP is available using the BandMasterX or EraseMaster passwords. Since the drive owner can define up to 16 data bands on the drive, each data band has its own password called BandMasterX where X is the number of the data band (0 through 15).

7.2.3 Default password

When the drive is shipped from the factory, all passwords are set to the value of MSID. This 32-byte random value is printed on the drive label and it can be read by the host electronically over the I/O. After receipt of the drive, it is the responsibility of the owner to use the default MSID password as the authority to change all other passwords to unique owner-specified values.

7.3 Random number generator (RNG)

The drive has a 32-byte hardware RNG that it is uses to derive encryption keys or, if requested to do so, to provide random numbers to the host for system use, including using these nu mbers as Authentication Keys ( p asswords) for the drive’s Admin and Locking SPs.

7.4 Drive locking

In addition to changing the passwords, as described in Section 7.2.3, the owner should also set the data access controls for the individual bands.

The variable "LockOnReset" should be set to "PowerCycle" to ensure that the data bands will be locked if power is lost. This scenario occurs if the drive is removed from its cabinet. The drive will not honor any data read or write requests until the bands have been unlocked. This prevents the user data from being accessed without the appropriate credentials when the drive has been removed from its cabinet and installed in another system.

When the drive is shipped from the factory, the firmware download port is locked and the drive will reject any attempt to download new firmware. Th e dr ive own er m ust use th e SI D cr ed en tia l to un loc k th e fir m wa re do wn load port before firmware updates will be accepted.

7.5 Data bands

When shipped from the factory, the drive is configured with a single data band called Band 0 ( also known as the Global Data Band) which comprises LBA 0 through LBA max. The host may alloca te Band1 by specifying a start LBA and an LBA range. The r eal est a te for this band is t aken from the Global Band. An ad ditional 14 Data Bands may be defined in a similar way (Band2 through Band15) but before these bands can be allocated LBA space, they must first be individually enabled using the EraseMaster password.

Data bands cannot overlap but they can be sequential with one ba nd e ndi ng at LBA (x) and the ne xt b eginnin g at LBA (x+1).

Each data band has its own drive-generated en cryption key and its own user -supplied p assword. The host may change the Encryption Key (see Section 7.6) or the password when required. The bands should be aligned to 4K LBA boundaries.

36 Cheetah 15K.7 FC Product Manual, Rev. B

7.6 Cryptographic erase

A significant feature of SEDs is the ability to perform a cryptographic erase. This involves the host telling the drive to change the data encryption key for a p ar ticu lar ban d. On ce chang ed , the data is no longer recoverable since it was written with one key and will be read using a different key. Since the drive overwrites the old key with the new one, and keeps no history of key changes, the user data can never be recovered. This is tantamount to an instantaneous data erase and is very useful if the drive is to be scrapped or redispositioned.

7.7 Authenticated firmware download

In addition to providing a locking mechanism to prevent unwanted firmware download attempts, the drive also only accepts download files which have been cryptographically signed by the appropriate Seagate Design Center.

Three conditions must be met before the drive will allow the download operation:

1. The download must be an SED file. A standard (base) drive (non-SED) file will be rejected.

2. The download file must be signed and authenticated.

3. As with a non-SED drive, the download file must pass the acceptance criteria for the drive. For example it must be applicable to the correct drive model, and have compatible revision and customer status.

7.8 Power requirements

7.9 Supported commands

The SED models support the following two commands in addition to the commands supported by the standard (non-SED) models as listed in Table 16:

• Security Protocol Out (B5h)

• Security Protocol In (A2h)

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 using 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 Fibre Channel Interface Manual. The drive implements selectable error recovery 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.

The drive firmware error recovery algorithms consists of 13 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 re-

38 Cheetah 15K.7 FC Product Manual, Rev. B

read or re-write attempt. The maximum level used by the drive in LBA recovery is determined by the read and write retry counts.

Table 5 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.

[1] These values are subject to change.

Setting these retry counts to a value below the default setting could result in an increased unrecovered error rate which may exceed the value given in this product manual. A setting of zero (0) will result in the drive not performing error recovery.

For example, suppose the Read/Write Recovery page has the RC bit set to 0, read retry count set to 4, and the recovery time limit field (Mode Sense page 01, bytes 10 and 11) set to FF FF hex (maximum). A four LBA Read command is allowed to take up to 253.11 msec recovery time for each of the four LBAs in the command. If the recovery time limit is set to 00 C8 he x (200 mse c de cimal) a four LBA r ead comman d is allowed to take up to 200 msec for all error recovery within that command. The use of the Recovery Time Limit field allows finer granularity on control of the time spent in error recovery. The re covery time limit only starts counting when the drive is exec uting error recovery and it restarts on each command. Therefore, each command’s tot a l re co very time is sub j ect to the recovery time limit. Note: A recover y time limit of 0 will use the drive’s default value of FF FF. Minimum recovery time limit is achieved by setting the Recovery Time Limit field to 00 01.

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.

40 Cheetah 15K.7 FC Product Manual, Rev. B

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 scann ed for defects prior to being pu t 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-servicing activity from BMS only impacts the first command that interrupted BMS, this results in a typical delay of about 1 ms.

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 disc.

Note. During Pre-Scan write verify commands, write performance may decrease by 50% until Pre-Scan

completes. Write performance testing shou ld be performed after Pre-Scan is complete. Th is 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.

Cheetah 15K.7 FC Product Manual, Rev. B 41

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 sectors that fail the comp ariso n result in the invocation of a rewrite and auto-reallocation process. The 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.

9.0 Installation

Cheetah 15K.7 FC disc drive installation is a plug-and- play pro cess. T her e are no jump ers, sw itch es, or term inators on the drive. Simply plug the drive into the host’s 40-pin Fibre Channel backpanel connector (FCSCA)

—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 27). 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 24 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 (discs level) and vertical (drive on its side) orientations, which are the two preferred mounting orientations.

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 6.4.1. In some cases, forced airflow may be required to keep temperatures at or below the temperatures specified in Section 6.4.1.

If forced air is necessary, possible air-flow patterns are shown in Figure 10. The air-flow patterns are created by fans either forcing or drawing air as shown in the illustrations. Conduction, convection, or other forced airflow patterns are acceptable as long as the temperature measurement guidelines of Section 6.4.1 are met.

9.4 Drive mounting

K x X = F < 15lb = 67N

Mount the drive using the bottom or side mounting holes . If you mount the drive using the b ottom holes, ensure 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:

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.

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

Cheetah 15K.7 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.

Note. When a Cheetah 15K.7 FC drive is connected in loops with previous Seagate FC drive products:

Barracuda 4LP FC (ST32171FC, ST34371FC, and ST34571FC) Barracuda 9FC (ST19171FC) Cheetah 4LP FC (ST34501FC) Cheetah 9FC (ST19101FC)

the connection of Port A and B for these products must follow the requirements in their product manuals.

Subject to buffer availability, the Cheetah 15K.7 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.

Cheetah 15K.7 FC Product Manual, Rev. B 57

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 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 dif fere nt versions of dr ive control firmware in the total pop ulation of

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

18, refer to Mode page

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: SAV = Current saved value.

DEF = Default value. Standard OEM drives are shipped configured this way. CHG = Changeable bits; indicates if default value is changeable.

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 12 shows the relationship between the PBC and FC-AL device.

[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)

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 cu rr ent return for the +5 volt po wer su pply is through th e 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 LED. The an ode is a ttached to the proper

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

66 Cheetah 15K.7 FC Product Manual, Rev. B

10.5.8 Active LED Out

The Active LED Out signal is driven by the drive as indicated in Table 25.

Table 25: Active LED Out conditions

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, each cylinder change 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 the current limit ing r esisto r 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 disc 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 disc drive. A pull down resistor, 1K, located with the PBC should be used to insure the bypass is enabled if the disc drive is not installed.

The Enable Bypass signal is active under failing conditions within the drive, on detection of the Loop Port Bypass primitive sequence, or on removal of the drive. In the bypass st ate the drive continue s to receive o n the inbound fibre. Enable Bypass may be deactivated by detection of a Loop Port Enable primitive sequence if the drive has completed self-test and a hardware failure is not present.

Failure modes detected by the disc 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 26. The state of these signals can be wired into the backplane socket or driven by logic on the backplane.

Table 26: Motor start control signals

Case Start_2 Start_1 Motor spin function

1 Low Low Motor 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.

Cheetah 15K.7 FC Product Manual, Rev. B 67

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 anel mu st pro vide add ress info rmation on the SEL line. Refer to table 27 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 29 on page 70.

Note. Table 27 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 being 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 requir es addr ess infor mation on 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.
