4.6 Programmable drive capacity
Using the MODE SELECT command, the drive can change its capacity to less than maximum. See the MODE SELECT (6)
parameter list table in the SAS Interface Manual, part number 100293071. A value of zero in the Number of Blocks field
indicates that the drive does not change the capacity it is currently formatted to have. A number other than zero and
less than the maximum number of LBAs in the Number of Blocks field changes the total drive capacity to the value in
the Number of Blocks field. A value greater than the maximum number of LBAs is rounded down to the maximum
capacity.
Seagate also provides SeaChest, a CLI tool for Windows and Linux operating systems to adjust capacity and perform
other drive management operations. Go to this page to download the tool:
https://www.seagate.com/support/software/seachest/
Or go here: https://github.com/Seagate/ToolBin/tree/master/SeaChest
4.7 Factory-installed options
OEMs may order the following items which are incorporated at the manufacturing facility during production or
packaged before shipping. Some options are (not an exhaustive list of possible options):
Other capacities can be ordered depending on LBA size requested and other factors.
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 provided by the single 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

4.8 Logical Block Provisioning
The drive follows SAS logical block provisioning where each LBA is either mapped or unmapped to physical NAND
media blocks based on user writes and unmap operations.
Behavior of logical block provisioning is found but send a READ CAPACITY 16 (9Eh) command to the drive.
Table 10 - Logical block provisioning options
Product Configuration LBPME LBPRZ
Non-SED Supported Supported
SED Supported Supported
A logical block provisioning management enabled (LBPME) bit set to one indicates that the logical unit implements
logical block provisioning management. An LBPME bit set to zero indicates that the logical unit is fully provisioned
and does not implement logical block provisioning management.
A logical block provisioning read zeros (LBPRZ) bit set to one indicates that, for an unmapped LBA specified by a read
operation, the device server sends user data with all bits set to zero to the data-in buffer. An LBPRZ bit set to zero
indicates that, for an unmapped LBA specified by a read operation, the device server may send user data with all bits
set to any value to the data-in buffer.
4.8.1 UNMAP
The UNMAP command asks the device server to break the association of a specific Logical Block address from a
Physical Block. This frees up the Physical Block from use and no longer requires it to contain user data. An unmapped
block responds to a READ command with data that is determined by the setting of the LBPRZ bit in the READ
CAPACITY parameter data.
4.8.2 FORMAT UNIT command
A device which supports Thin Provisioning is capable of performing a SCSI FORMAT UNIT command which allocates
Logical Blocks Addresses that are not linked to Physical Block Locations. A FORMAT command causes all LBAs to
become unmapped.
4.8.3 Protection Information (PI) and Security (SED)
In SCSI devices, umapped LBAs are defined as part of the Logical Block Provisioning model. Support of this model is
indicated by the LBPME bit having a value of '1' in the READ CAPACITY (16) parameter data.
When a region of LBA's are erased through cryptographic erase, as part of the erase, the LBAs are not unmapped.
If the host attempts to access an unmapped or trimmed LBA, the drive returns 0 data for unmapped LBAs. The drive
shall report a value of '0' in the LBPRZ field returned in the READ CAPACITY (16) parameter data.
If the host attempts to access an unmapped LBA on a drive that has been formatted with Protection Information (PI),
the drive shall return scrambled PI data for that LBA. Depending on the value of the RDPROTECT field in the
data-access command CDB, this may result in the drive returning a standard PI error to the host.
If the host reduces the addressable capacity of the drive via a MODE SELECT command, the drive shall unmap or trim
any LBA within the inaccessible region of the device.

5.2 Performance characteristics
5.2.1 Response time
Response time measurements are taken with nominal power at 25°C ambient temperature. The typical values in the
table below are defined as follows:
Page-to-page response time is an average of all possible page-to-page accesses for a sequentially preconditioned
drive.
Average response time is a true statistical random average of at least 5000 measurements of accesses between
programmable pages on a randomly preconditioned drive.
Table 12 - Typical Response Time (μsec)
Page to Page 115 25
Read Write Notes
Execution time measured from receipt of the
Command to the Response. Assumes no errors.
Average Latency 115 25
Typical response times are measured under
nominal conditions of temperature and voltage
as measured on a representative sample of
drives.
These drives provide the highest possible performance under typical conditions. However, due to the nature of Flash
memory technologies there are many factors that can result in values different than those stated in this specification.
5.2.2 FORMAT UNIT command execution time for 512-byte LBA's (minutes)
The device may be formatted as either a Thin Provisioned device or a Fully Provisioned device.
The default format is Thin Provisioned and is recommended for most applications.
Thin Provisioning provides the most flexibility for the device to manage the flash medium to maximize endurance.
The duration of the FORMAT UNIT command is based on capacity. The format processing rate is typically 20GB per
second. For example the 3840GB XS3840SE70004 device completes formatting in 38 seconds.

Due to the nature of Flash memory technologies, many factors can result in values different from those specified here.
Bandwidth limitations in the host adapter, operating system, driver limitations, and other factors can cause
discrepancies.
When evaluating performance of SSD devices, it is recommended to measure performance of the device in a way that
resembles the targeted application using real world data and workloads. Test time should also be large enough to
make sure sustainable metrics and measures are obtained.

5.3 Start/stop time
The drive accepts the commands listed in the SAS Interface Manual less than four seconds after DC power is applied.
If the drive receives a NOTIFY (ENABLE SPINUP) primitive through either port and has not received a START STOP UNIT
command with the START bit equal to 0, the drive becomes ready for normal operations within 10 seconds (excluding
the error recovery procedure).
If the drive receives a START STOP UNIT command with the START bit equal to 0 before receiving a NOTIFY (ENABLE
SPINUP) primitive, the drive waits for a START STOP UNIT command with the START bit equal to 1. After receiving a
START STOP UNIT command with the START bit equal to 1, the drive waits for a NOTIFY (ENABLE SPINUP) primitive.
After receiving a NOTIFY (ENABLE SPINUP) primitive through either port, the drive becomes ready for normal
operations within 5 seconds.
If the drive receives a START STOP UNIT command with the START bit and IMMED bit equal to 1 and does not receive a
NOTIFY (ENABLE SPINUP) primitive within 5 seconds, the drive fails the START STOP UNIT command.
The START STOP UNIT command may be used to command the drive to stop. Stop time is three seconds (maximum)
from removal of DC power. SCSI stop time is three seconds.
The drive support pin 3 POWER DISABLE as defined by the T10 SAS-3 specification.
5.3.1 Caching write data
All write data is stored in non-volatile memory before acknowledging the SAS write operation. Non-volatile memory is
both NAND and DRAM that is written to NAND during any power interruption.
The drive never sends a deferred write error status.
The Write Cache Enable (WCE) bit in mode page 08h may be set to 0 or 1 but does not change the operation of the
drive.
The SYNCHRONIZE_CACHE command does not alter the state or location of written data. The response from the drive
for this command indicates that all prior write commands have been completed and acknowledged.
Section Section 12.3.2 MODE SENSE data, on page 76 shows the mode default settings for the drive.
Seagate Nytro 3732, 3532, and 3332 SAS SSD Product Manual, Rev B 21
www.seagate.com
5.3.2 Prefetch operation
If the Prefetch feature is enabled, data in contiguous logical blocks on the medium immediately beyond what 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 prefetch 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 medium 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.

As NAND Flash devices age with use, the capability
of the media to retain a programmed value begins
to deteriorate. This deterioration is affected by the
number of times a particular memory cell is
programmed and subsequently erased. When a
device is new, it has a powered off data retention
capability of up to several years. With use the
retention capability of the device is reduced.
Temperature also has an effect on how long a Flash
component can retain its programmed value with
power removed. At high temperature the retention
capabilities of the device are reduced. Data
retention is not an issue with power applied to the
SSD. The SSD drive contains firmware and hardware
features that can monitor and refresh memory cells
when power is applied.
Endurance rating is the expected amount of host
data that can be written by product when
subjected to a specified workload at a specified
operating and storage temperature over the
specified product life. For the specific workload to
achieve this level of endurance, please reference
JEDEC Specification JESD218. TBW is defined as
1x1012 Bytes.
Limited Warranty with Media Usage provides
coverage for the warranty period or until the SSD
Percentage Used Endurance Indicator, as defined in
Section 3.2.6, reaches 100 whichever comes first.

6.3 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 7.2 Power
consumption, on page 33.
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.
6.3.1 Unrecoverable Errors
An unrecoverable data error is a failure of the drive to recover data from the media. These errors occur due to read or
write problems. Unrecoverable data errors are only detected during read operations, but not caused by the read. If an
unrecoverable data error is detected, a MEDIUM ERROR (03h) in the Sense Key is reported. Multiple unrecoverable
data errors resulting from the same cause are treated as one error.
6.3.2 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.
6.4 Endurance management
Customer satisfaction with Solid State Drives can be directly related to the internal algorithms which an SSD uses to
manage the limited number of Program-Erase (PE) cycles that NAND Flash can withstand. These algorithms consist of
Wear Leveling, Garbage Collection, Write Amplification, Unmap, Data Retention, Lifetime Endurance Management.
6.4.1 Wear leveling
The drive uses Wear Leveling to make sure that all Flash cells are written to or exercised as evenly as possible to avoid
hot spots where some cells are used up faster than other locations. The drive automatically manages Wear Leveling
without user interaction. The Seagate algorithm operates only when needed to ensure reliable product operation.
6.4.2 Garbage collection
The drive uses Garbage Collection to consolidate valid user data into a common cell range freeing up unused or
obsolete locations to be erased and used for future storage needs. The drive automatically manages Garbage
Collection without user interaction. The Seagate algorithm operates only when needed to ensure reliable product
operation.
Seagate Nytro 3732, 3532, and 3332 SAS SSD Product Manual, Rev B 25
www.seagate.com
6.4.3 Write amplification
While Write Amplification is not an algorithm, it is a major characteristic of SSDs. Write Amplification must be
accounted for by all the algorithms that the SSD implements. The Write Amplification Factor of an SSD is the ratio of
Host/User data requested to be written to the actual amount of data written by the SSD internal to account for the
user data and the housekeeping activities such as Wear Leveling and Garbage Collection. The Write Amplification
Factor of an SSD can also be directly affected by the characteristics of the host data being sent to the SSD to write. The
best Write Amplification Factor is achieved for data that is written in sequential LBAs that are aligned on 4KB
boundaries. The worst case Write Amplification Factor occurs for randomly written LBA's of transfer sizes that are less
than 4KB and that originate on LBA's that are not on 4KB boundaries.
6.4.4 UNMAP
Use of the UNMAP command reduces the Write Amplification Factor of the drive during housekeeping tasks such as
Wear Leveling and Garbage Collection. This happens because the drive does not need to retain data which has been
classified by the host as obsolete.
6.4.5 Data retention
Data Retention is another major characteristic of SSDs that must be accounted for by all the algorithms that the SSD
implements. While powered up, the Data Retention of SSD cells are monitored and rewritten if the cell levels decay to
an unexpected level. Data Retention when the drive is powered off is affected by Program and Erase (PE) cycles and
the temperature of the drive when stored.
6.4.6 Write stream tagging
The Write Stream command is an optional SAS bus command for the host to pass a contextual data tag to SSD. The
SSD stores data context together to minimize write amplification when data is unmapped or over written. The Nytro
3032 Series supports creating 32 streams but optimal benefit is achieved when 8 or less streams are concurrently
active.
6.4.7 SSD percentage used endurance indicator
An application can interrogate the drive through the host to determine an estimate of the percentage of device life
that has been used. To accomplish this, issue a LOG SENSE command to log page 0x11. This allows applications to read
the contents of the Percentage Used Endurance Indicator parameter code. The Percentage Used Endurance Indicator
is defined in the T10 document SBC-4 available from the T10 committee.
6.5 Reliability and service
Integrators can enhance the reliability of Seagate Nytro 3032 Series SAS SSD drives by ensuring that the drive receives
adequate cooling. Section 12.4.2 Physical characteristics, on page 82 provides temperature measurements and other
information that may be used to enhance the service life of the drive. Section 11.2 Cooling, on page 65 provides
recommended air-flow information.
Seagate Nytro 3732, 3532, and 3332 SAS SSD Product Manual, Rev B 26
www.seagate.com
6.5.1 Annualized Failure Rate (AFR) and Mean Time Between Failure (MTBF)
The production drive shall achieve an AFR of 0.35% (MTBF of 2,500,000 hours) when operated in an environment that
ensures the case temperatures do not exceed the values specified in Section 7.3 Environmental limits, on page 51.
Operation at case temperatures outside the specifications in Section 7.3 Environmental limits, on page 51 may increase
the product AFR (decrease the MTBF). The AFR (MTBF) is a population statistic not relevant to individual units.
The AFR (MTBF) specification is based on the following assumptions for Enterprise Storage System environments:
8760 power-on hours per year.
250 average on/off cycles per year.
Operations at nominal voltages.
Systems will provide adequate cooling to ensure the case temperatures specified in Section 11.2 Cooling, on page 65
are not exceeded. Temperatures outside the specifications in Section 11.2 Cooling, on page 65 will increase the
product AFR and decrease the MTBF.
6.5.2 Preventive maintenance
No routine scheduled preventive maintenance is required.
6.5.3 Hot plugging the drive
When a drive is powered on by switching the power or hot plugged, the drive runs a self test before attempting to
communicate on its' interfaces. When the self test completes successfully, the drive initiates a Link Reset starting with
the Out Of Band sequence (OOB). An attached device should respond to the link reset. If the link reset attempt fails, or
any time the drive looses sync, the drive initiated link reset. The drive will initiate link reset once per second but
alternates between port A and B. Therefore each port will attempt a link reset once per 2 seconds assuming both ports
are out of sync.
If the self-test fails, the drive does not respond to link reset on the failing port.
NOTE It is the responsibility of the systems integrator to assure that no temperature,
6.5.4 SMART
SMART. 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 administrators to back up the data before an actual failure occurs.
NOTE The drive's firmware monitors specific attributes for degradation over time but
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.

carrier prior to inserting it into the system.
can't predict instantaneous drive failures.
Seagate Nytro 3732, 3532, and 3332 SAS SSD Product Manual, Rev B 27
www.seagate.com
6.5.4.1 Controlling SMART.
The operating mode of SMART. 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 SMART. feature. Setting the DEXCPT bit disables all
SMART. functions. When enabled, SMART. 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.
An application can measure off-line attributes and force the drive to save the data by using the REZERO UNIT
command. Forcing SMART. resets the timer so that the next scheduled interrupt is in one hour.
An application can interrogate the drive through the host to determine the time remaining before the next scheduled
measurement and data logging process occurs. To accomplish this, issue a LOG SENSE command to log page 0x3E.
This allows applications to control when SMART. interruptions occur. Forcing SMART. with the REZERO UNIT command
resets the timer.
6.5.4.2 Performance impact
SMART. attribute data is saved to the media so that the events that caused a predictive failure can be recreated. The
drive measures and saves parameters once every hour subject to an idle period on the drive interfaces. The process of
measuring off-line attribute data and saving data to the media is interruptible. The maximum on-line only processing
delay is summarized in the following table:
Table 16 - Maximum processing delay
Fully-enabled delay DEXCPT = 0
SMART. delay times 75 ms
6.5.4.3 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.
6.5.4.4 Determining rate
SMART. monitors the rate at which errors occur and signals a predictive failure if the rate of degraded errors increases
to an unacceptable level. To determine rate, error events are logged and compared to the number of total operations
for a given attribute. The interval defines the number of operations over which to measure the rate. The counter that
keeps track of the current number of operations is referred to as the Interval Counter.
SMART. 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 algorithm that SMART. uses to record rates of error is to set
thresholds for the number of errors and appropriate 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.
6.5.4.5 Predictive failures
SMART. 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 each time the error 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.

6.5.5 Thermal monitor
Seagate Nytro 3032 Series SAS SSD 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. (i.e., the reference temperature value)
3. Saves a SMART. 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 threshold. The temperature is measured at power-up and then at ten-minute intervals 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.
This feature is controlled by the Enable Warning (EWasc) bit, and the reporting mechanism is controlled by the
Method of Reporting Informational Exceptions field (MRIE) on the Informational Exceptions Control (IEC) mode page
(1Ch).
6.5.6 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 every logical block
address (LBA) of the drive. The short test is time-restricted and limited in length--it does not scan the entire media
contents, but does some fundamental tests and scans portions of the media. If DST encounters an error during either
of these tests, it reports a "diagnostic failed" condition. If the drive fails the test, remove it from service and return it to
Seagate for service.
6.5.6.1 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 drive parameters are not modified to test the drive more stringently,
and the recovery capabilities 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 recovery processes required to recover the data.
The following conditions are considered DST failure conditions:
Read error after recovery attempts are exhausted
Write error after recovery attempts are exhausted
6.5.6.2 Implementation
This section provides all of the information necessary to implement the DST function on this drive.
6.5.6.3 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 UNIT, or another DST. It is the responsibility of the host application to determine the "not ready"
cause.
Seagate Nytro 3732, 3532, and 3332 SAS SSD Product Manual, Rev B 29
www.seagate.com
6.5.6.4 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. Each test consists of two segments: an electrical test segment
and a read/verify scan segment.
DST has two testing options:
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 contents, 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 "diagnostic failed"
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 components. The read operation tests the
media contents. The integrity of the media is checked through a read/verify scan of the media. The anticipated length
of the Extended test is reported through the Control Mode page.
6.5.6.5 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 beginning of the self-test results log parameter 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 Self-Test
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. The self-test results 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.
6.5.6.6 Abort
There are several ways to abort a diagnostic. Applications can use a SCSI Bus Reset or a Bus Device Reset message to
abort the diagnostic.
Applications 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).

Contact the authorized Seagate distributor to purchase additional boxes. Seagate recommends shipping by an
air-ride carrier experienced in handling computer equipment.
6.5.8.1 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.
6.5.8.2 Storage
You can store the drive for a maximum of 180 days in the original unopened Seagate shipping package or 60 days,
unpackaged, in the defined non-operating limits (refer to environmental section in this manual). You can extend
storage to 1 year packaged or unpackaged under optimal environmental conditions (<40°C, <40% relative humidity
non-condensing, and non-corrosive environment). During any storage period you must follow the drive
non-operational temperature, humidity, wet bulb, atmospheric conditions, shock, vibration, magnetic and electrical
field specifications.

7. Physical and electrical specifications
This section provides information relating to the physical and electrical characteristics of the drive.
7.1 Power specifications
The 2.5" drive receives DC power (+5V and +12V) through the standard SAS interface. The minimum current loading
for each supply voltage is not less than 1.7% of the maximum operating current shown. Both +5V and +12V supplies
should employ separate ground returns.
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.

7.1.1 Conducted noise immunity
Noise is specified as a periodic and random distribution of frequencies covering a defined frequency. Maximum
allowed noise values given below are peak-to-peak measurements and apply at the drive power connector.
Table 19 - Maximum allowed peak-to-peak noise
+5 V 250 mV pp from 100 Hz to 20 MHz.
450 mV pp from 100 Hz to 100 KHz.
+12 V 250 mV pp from 100 KHz to 20 MHz.
150 mV pp from 20 MHz to 80 MHz.
7.1.2 Power sequencing
The drive does not require power sequencing. The drive protects against inadvertent writing during power-up and
down.
7.2 Power consumption
Power requirements for the drives are listed in the tables in this section. Typical power measurements are based on an
average of drives tested, under nominal conditions, using the listed input voltage at 60°C internal temperature.
Startup power
Startup power is measured from the time of power-on to the time that the drive reaches operating condition and
can process media access commands.
Peak operating mode
During peak operating mode, the drive is tested in various read and write access patterns to simulate the
worst-case power consumption.
Idle mode power
Idle mode power is measured with the drive powered up and ready for media access commands, with no media
access commands having been received from the host.
7.2.1 Direct Current consumption by voltage rail
The tables in Section 7.2.2 Power consumption by model and capacity, on page 34 list the single port active power
consumption measured under various workloads for each mode.
Points to be noted about the tables:
Measured with average reading DC ammeter. Instantaneous +12V current peaks will exceed these values. Power
supply at nominal voltage. N (number of drives tested) = 6, 60 Degrees C internal.
For +12 V, a -10% tolerance is allowed during initial start but must return to ±5% before reaching ready state. The
±5% must be maintained after the drive signifies that its power-up sequence has been completed and that the
drive is able to accept selection by the host initiator.
Delayed Motor Start condition occurs after OOB and Speed Negotiation completes but before the drive has
received the Notify Spinup primitive.
See Section 7.1.1 Conducted noise immunity, on page 33. Specified voltage tolerance includes ripple, noise, and
transient response.

7.3 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 84.2°F (29°C).
NOTE To maintain optimal performance drives should be run at nominal case
temperatures.
7.3.1 Temperature
7.3.1.1 Operating
The drive meets the operating specifications over a 32°F to 167°F (0°C to 70°C) drive internal temperature range with a
maximum temperature gradient of 36°F (20°C) per hour.
NOTE Internal temperature swings greater than 55°C during over a 3 day time period
may cause an elevated read error rate.
The maximum allowable drive internal temperature is 70°C. If the enclosure environment is unable to keep the
internal temperature below this value the drive will reduce write activity to avoid over temperature condition. When
the internal temperature is equal or greater than 65°C the drive will issue a SMART thermal warning.
The MTBF specification for the drive assumes the operating environment is designed to maintain nominal internal
temperature. The rated MTBF is based upon a sustained internal temperature of 122°F (50°C). Occasional excursions in
operating temperature between the rated MTBF temperature and the maximum drive operating internal temperature
may occur without impact to the rated MTBF temperature. However continual or sustained operation at internal
temperatures beyond the rated MTBF temperature will degrade the drive MTBF and reduce product reliability.
Air flow across the drive is expected under moderate to heavy write data workloads to stay under internal
temperature limits described in this section. To confirm that the required cooling is provided, place the drive in its final
mechanical configuration, and perform highest data throughput for the given application. If unknown writing large
transfers sequentially on both port will consume the most current. After the temperatures stabilize, read the internal
temperature of the drive using Seagate SeaChest or SeaTools utilities available at http://www.seagate.com.
7.3.1.2 Non-operating
-40° to 167°F (-40° to 75°C) package ambient with a maximum gradient of 36°F (20°C) per hour. This specification
assumes that the drive is packaged in the shipping container designed by Seagate for use with drive.
7.3.2 Relative humidity
The values below assume that no condensation on the drive occurs.
Operating
5% to 95% non-condensing relative humidity with a maximum gradient of 20% per hour.
Non-operating
5% to 95% non-condensing relative humidity.
Seagate Nytro 3732, 3532, and 3332 SAS SSD Product Manual, Rev B 51
www.seagate.com
7.3.3 Effective altitude (sea level)
Operating
-1000 to +10,000 feet (-304.8 to +3048 meters)
Non-operating
-1000 to +40,000 feet (-304.8 to +12,192 meters)
7.3.4 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, resonances 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 10, Recommended mounting, on page 67, and in accordance with the restrictions the
Section 11.3 Drive mounting, on page 67.
7.3.4.1 Shock
Operating - normal
The drive, as installed for normal operation, shall operate error free while subjected to intermittent shock not
exceeding:
1000 Gs at a maximum duration of 0.5ms (half sinewave)
Shock may be applied in the X, Y, or Z axis. Shock is not to be repeated more than once every 2 seconds.
NOTE This specification does not cover connection issues that may result from testing
at this level.
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 non-repetitive shock not exceeding:
1000 Gs at a maximum duration of 0.5ms (half sinewave), shall not exhibit device damage or performance
degradation.
Shock may be applied in the X, Y, or Z axis.
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 pack carton for minimum drive quantities and proper drive placement.
Seagate Nytro 3732, 3532, and 3332 SAS SSD Product Manual, Rev B 52

7.3.4.2 Vibration
Operating - normal
The drive s installed for normal operation, shall comply with the complete specified performance while subjected to
vibration applied in the X, Y, or Z axis.
Operating normal translational random shaped profile: 20 - 2000 Hz, 11.08 GRMS
Operating - abnormal
Equipment as installed for normal operation shall not incur physical damage while subjected to periodic vibration:
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 shaped profile: 20 - 2000 Hz, 11.08 GRMS
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 vibration.
Vibration may be applied in the X, Y, or Z axis.
Non-operating translational random shaped profile: 20 - 2000 Hz, 11.08 GRMS
NOTE This specification does not cover connection issues that may result from testing
at this level.
7.3.5 Air cleanliness
The drive is designed to operate in a typical office environment with minimal environmental control.
7.3.6 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 exposing any electronic components 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 the most damaging. 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.
Seagate recommends that data centers be kept clean by monitoring and controlling the dust and gaseous
contamination. Gaseous contamination should be within ANSI/ISA S71.04-2013 G2 classification levels (as measured
on copper and silver coupons), and dust contamination to ISO 14644-1 Class 8 standards, and MTBF rated conditions
as defined in the Annualized Failure Rate (AFR) and Mean Time Between Failure (MTBF) section.

8. About FIPS
The Federal Information Processing Standard (FIPS) Publication 140-2 is a U.S. Government Computer Security
Standard used to accredit cryptographic modules. It is titled 'Security Requirements for Cryptographic Modules (FIPS
PUB 140-2)' and is issued by the National Institute of Standards and Technology (NIST).
8.1 Purpose
This standard specifies the security requirements that will be satisfied by a cryptographic module utilized within a
security system protecting sensitive but unclassified information. The standard provides four increasing, qualitative
levels of security: Level 1, Level 2, Level 3 and Level 4. These levels are intended to cover the wide range of potential
applications and environments in which cryptographic modules may be employed.
8.2 Validation Program
Products that claim conformance to this standard are validated by the Cryptographic Module Validation Program
(CMVP) which is a joint effort between National Institute of Standards and Technology (NIST) and the
Communications Security Establishment (CSE) of the Government of Canada. Products validated as conforming to
FIPS 140-2 are accepted by the Federal agencies of both countries for the protection of sensitive information (United
States) or Designated Information (Canada).
In the CMVP, vendors of cryptographic modules use independent, accredited testing laboratories to have their
modules tested. National Voluntary Laboratory Accreditation Program (NVLAP) accredited laboratories perform
cryptographic module compliance/conformance testing.
8.3 Seagate Enterprise SED
The SEDs referenced in this Product Manual have been validated by CMVP and have been thoroughly tested by a
NVLAP accredited lab to satisfy FIPS 140-2 Level 2 requirements. In order to operate in FIPS Approved Mode of
Operation, these SEDs require security initialization. For more information, refer to Security Rules section in the Security
Policy document uploaded on the NIST website. For product certification status visit
https://csrc.nist.gov/projects/cryptographic-module-validation-program/validated-modules/search.

www.seagate.com
8.4 Security Level 2
Security Level 2 enhances the physical security mechanisms of a Security Level 1 cryptographic module by adding the
requirement for tamper-evidence, which includes the use of tamper-evident coatings or seals on removable covers of
the module.
Tamper evident coatings or seals are placed on a cryptographic module so that the coating or seal must be broken to
attain physical access to the critical security parameters (CSP) within the module.
Tamper-evident seals (example shown in Figure 7, Example of FIPS tamper evidence labels, on page 57) are placed on
covers to protect against unauthorized physical access.
In addition Security Level 2 requires, at a minimum, role-based authentication in which a cryptographic module
authenticates the authorization of an operator to assume a specific role and perform a corresponding set of services.

9. 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.
The Trusted Computing Group (TCG) is an organization sponsored and operated by companies in the computer,
storage and digital communications industry. The Seagate 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 the appropriate command payloads.
9.1 Data encryption
Encrypting drives use one in-line encryption engine for each port, employing AES-256 data encryption 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 and cannot be disabled.
The 32-byte Data Encryption Key (DEK) is a random number which is generated by the drive, never 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 possible 16 data bands (see Section 9.5 Data bands, on page 59).
9.2 Controlled access
The drive has two security providers (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.
9.2.1 Admin SP
The Admin SP allows the drive's owner to enable or disable firmware download operations (see Section 6.4). Access to
the Admin SP is available using the SID (Secure ID) password or the MSID (Manufacturers Secure ID) password.
9.2.2 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).
Seagate Nytro 3732, 3532, and 3332 SAS SSD Product Manual, Rev B 58
www.seagate.com
9.2.3 Default password
When the drive is shipped from the factory, all passwords are set to the value of MSID. This 32-byte random value can
only be read by the host electronically over the interface. 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.
9.3 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 numbers as Authentication Keys (passwords) for
the drive's Admin and Locking SPs.
9.4 Drive locking
In addition to changing the passwords, as described in Section 9.2.3 Default password, on page 59, 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. In
addition ReadLockEnabled and WriteLockEnabled must be set to true in the locking table in order for the bands
LockOnReset setting of PowerCycle to actually lock access to the band when a PowerCycle event occurs. 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 unlocked allowing the drive to accept any
attempt to download new firmware. The drive owner must use the SID credential to lock the firmware download port
before firmware updates will be rejected.
9.5 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 allocate Band1 by specifying a start LBA
and an LBA range. The real estate for this band is taken from the Global Band. An additional 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 band ending at LBA (x) and the next beginning at LBA
(x+1).
Each data band has its own drive-generated encryption key and its own user-supplied password. The host may
change the Encryption Key or the password when required. The bands shall be aligned to 4KB LBA boundaries.
Seagate Nytro 3732, 3532, and 3332 SAS SSD Product Manual, Rev B 59
www.seagate.com
9.6 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 particular band. Once changed, 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. Erased sectors will be unmapped and
return all zeros if read.
9.7 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 digitally 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.
9.8 Power requirements
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. See the tables in Section 7.2 Power consumption, on page 33 for power
requirements on the standard (non-SED) drive models.
Seagate Nytro 3732, 3532, and 3332 SAS SSD Product Manual, Rev B 60
www.seagate.com
9.9 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 Ta ble27, Supported commands, on page69.
SECURITY PROTOCOL OUT (B5h)
SECURITY PROTOCOL IN (A2h)
9.10 Sanitize - Cryptographic Erase
This command cryptographically erases all user data on the drive by destroying the current data encryption key and
replacing it with a new data encryption key randomly generated by the drive. Sanitize CRYPTOGRAPHIC ERASE is a
SCSI CDB Op code 48h and selecting the service action code 3 (CRYPTOGRAPHIC ERASE).
9.11 RevertSP
SED models will support the RevertSP feature which erases all data in all bands on the device and returns the contents
of all SPs (Security Providers) on the device to their original factory state. In order to execute the RevertSP method the
unique PSID (Physical Secure ID) printed on the drive label must be provided. PSID is not electronically accessible and
can only be manually read from the drive label or scanned in via the 2D barcode.

10. 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 management and SAS system error
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:
Auto-Reallocation (see Section 10.4 Auto-Reallocation, on page 63)
The read error rates and specified storage capacities are not dependent on host (initiator) defect management
routines.
10.1 Drive internal defects/errors
During the initial drive manufacturing test 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). At factory format
time, these known defects are also deallocated, that is, marked as retired and the location listed in the defects
reallocation table. The 'P' list is not 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 SAS Interface Manual. Also, more
information on the drive Error Recovery philosophy is presented in the SAS Interface Manual.
The drive uses a vendor unique format to report defects via the READ DEFECT DATA command pending T10
standardization of a format for Solid State Devices. This format defect type is defined as 110b in the SCSI FORMAT UNIT
command. The definition of the 110b format is defined in the following table.

10.2 Drive error recovery procedures
When an error occurs during drive operation, the drive performs error recovery procedures to attempt to recover the
data. The error recovery procedures used are not user changeable.
10.3 SAS system errors
Information on the reporting of operational errors across the interface is given in the SAS Interface Manual. The SSP
Response returns information to the host about numerous kinds of errors. 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 SAS 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.
10.4 Auto-Reallocation
Auto-Reallocation allows the drive to reallocate unreadable locations on a subsequent write command if the recovery
process deems the location to be defective. The drive performs auto-reallocation on every WRITE command. With
each write to a Logical LBA, the drive writes the data to a different physical media location. Physical locations that
return unrecoverable errors are retired during future WRITE attempts and associated recovery process.
This is in contrast to the system having to use the REASSIGN BLOCKS command to reassign a location that was
unreadable and then generate a WRITE command to rewrite the data. This operation requires that AWRE and ARRE are
enabled which is the default setting from the Seagate factory.
10.5 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 drive, transfers 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 LBAs 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, except 528.
512 LBA size is used here as common example.

10.5.1 Levels of PI
There are 4 types of Protection Information.
Typ e 0 - Describes a drive that is not formatted with PI information bytes. This allows for legacy support in non-PI
systems.
Typ e 1 - Provides support of PI protection using 10 and 16 byte commands. The RDPROTECT and WRTPROTECT 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.
Typ e 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 RDPROTECT and WRTPROTECT bits are nonzero
values. Type 2 does allow the use of 10 and 16 byte commands with zero values in the RDPROTECT and WRTPROTECT
fields. The drive will generate 8 bytes of Protection Information (e.g. 0xFFFFFFFF) to be stored on the media, but the 8
bytes will not be transferred to the host during a READ command.
Typ e 3 - Seagate products do not support Type 3.
10.5.2 Setting and determining the current Type Level
A drive is initialized to a type of PI by using the FORMAT UNIT command on a PI capable drive. 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. A drive can only be formatted to a single PI Type. It can be changed at anytime to a new Type but
requires a FORMAT UNIT command which destroys all existing data on the drive. No other vehicle for changing the PI
type is provided by the T10 SBC-4 specification.
Type 1 PI FORMAT UNIT CDB command: 04 90 00 00 00 00, parameter data: 00 A0 00 00
Type 2 PI FORMAT UNIT CDB command: 04 D0 00 00 00 00, parameter data: 00 A0 00 00
10.5.3 Identifying a Protection Information drive
The Standard INQUIRY data provides a bit to indicate if PI is support by the drive. Vital Product Descriptor (VPD) page
0x86 provides bits to indicate the PI Types supported and which PI fields the drive supports checking.
NOTE For further details with respect to PI, please refer to SCSI Block Commands - 4
(SBC-4) Standard documentation.

11. Installation
Seagate Nytro 3000 SAS SSD drive installation is a plug-and-play process. There are no jumpers on the drive.
SAS drives are designed to be used in a host system that provides a SAS-compatible backplane with bays designed to
accommodate the drive. In such systems, the host system typically provides a carrier or tray into which the drive must
be mounted. Mount the drive to the carrier or tray provided by the host system using four M3 x 0.5 metric screws.
When tightening the screws, use a maximum torque of 4.5 in-lb +/- 0.45 in-lb. Do not over-tighten or force the screws.
The drive can be mounted in any orientation.
NOTE SAS drives are designed to be attached to the host system without I/O or power
Slide the carrier or tray into the appropriate bay in the host system using the instructions provided by the host system.
This connects the drive directly to the system’s SAS connector. The SAS connector is normally located on a SAS
backpanel. See Section 12.4.1 SAS physical interface, on page 79 for additional information about these connectors.
Power is supplied through the SAS connector.
The drive is shipped from the factory low-level formatted in 512-byte logical blocks. Reformatting the drive is only
required if the application requires a different logical block size.
Figure 8 Physical interface
cables. If the intent is to use the drive in a non-backplane host system,
connecting the drive using high-quality cables is acceptable as long as the I/O
cable length does not exceed 10 meters (32.8 feet).
11.1 Drive orientation
The drive may be mounted in any orientation. All drive performance characterizations, however, have been done with
the drive in horizontal (level) and vertical (drive on its side) orientations, which are the two preferred mounting
orientations.
11.2 Cooling
Cabinet cooling must be designed by the customer so that the temperature of the drive will not exceed temperature
conditions specified in Section 7.3.1 Temperature, on page 51.
The rack, cabinet, or drawer environment for the drive must provide heat removal from the assembly. The system
designer should confirm that adequate heat removal is provided using the temperature measurement guidelines
described in Section 7.3.1 Temperature, on page 51.
Seagate Nytro 3732, 3532, and 3332 SAS SSD Product Manual, Rev B 65
www.seagate.com
Forced air flow may be required to keep temperatures at or below the temperatures specified in Section 7.3.1
Temperature, on page 51 in which case the drive should be oriented, or air flow directed, so that the least amount of air
flow resistance is created while providing air flow. Also, the shortest possible path between the air inlet and exit
should be chosen to minimize the travel length of air heated by the drive and other heat sources within the rack,
cabinet, or drawer environment.
If forced air is determined to be necessary, possible air-flow patterns are shown in Figure 9, Air Flow, on page 66. The
air-flow patterns are created by one or more 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 7.3.1 Temperature, on page 51 are met.

11.3 Drive mounting
Mount the drive using the bottom or side mounting holes. If mounting the drive using the bottom holes, ensure not
to 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 following 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.
Figure 10 Recommended mounting
NOTE Image may not represent actual product, for reference only.
11.4 Grounding
Signal ground (PCBA) and case 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 drive with no electrically isolating shock
mounts. If it is desired for the system chassis to not be connected to the drive 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 designers 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.

12.2 Dual port support
Seagate Nytro 3000 SAS SSD SAS drives have two independent ports. These ports may be connected in the same or
different SCSI domains. Each drive port has a unique SAS address. The two ports have the capability of independent
port clocking (e.g. both ports can run at 12Gb/s or the first port can run at 12Gb/s while the second port runs at
6Gb/s.) The supported link rates are 1.5, 3.0, 6.0 or 12.0 Gb/s. Subject to buffer availability, the Seagate Nytro 3000 SAS
SSD drives support:
Concurrent port transfers -- The drive supports receiving COMMAND, TASK management transfers on both ports
at the same time.

Bytes 16 through 26 (Product ID) reflect the model of drive in ASCII.
12.3.2 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 changeable.
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 is "ready." An attempt to do so results in a "Check Condition" status.
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.
Seagate Nytro 3732, 3532, and 3332 SAS SSD Product Manual, Rev B 76
www.seagate.com
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. 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 that
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.
NOTE Because there are often several different versions of drive control firmware in
the total population of drives in the field, the MODE SENSE values given in the
following tables may not exactly match those of some drives.

Pins P1 and P2: When behind a SAS Drive plug connector, these pins
connect only to each other.
12.4.6 Power--check redundancy with other Power section
The drive receives power (+5 volts and +12 volts) through the SAS device connector.
Three +12 volt pins provide power to the drive, 2 short and 1 long.
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.
Three +5 volt pins provide power to the drive, 2 short and 1 long. The current return for the +5 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.
Current to the drive through the long power pins may be limited by the system to reduce inrush current to the drive
during hot plugging.
There is no power on sequencing requirements between the +12 volts and +5 volts inputs.

12.6 SAS-3 Specification compliance
Seagate SAS-3 compatible drives are compliant with the latest SAS-3 Specification (T10/BSR INCITS 519 rev. 06).
The main difference from SAS-2 is the Tx and Rx training that allows the host and drive to adjust the amplitude and
emphasis values to the channel. The receiver still employs Decision Feedback Equalizer (DFE) and Feed Forward
Equalizer (FFE) circuitry to accomplish this training.
