1.0 Scope This manual describes Seagate Technology® LLC, Constellation.2TM SAS (Serial Attached SCSI) disk drives. Constellation.2 SAS drives support the SAS Protocol specifications to the extent described in this manual. The SAS Interface Manual (part number 100293071) describes the general SAS characteristics of this and other Seagate SAS drives.
2.0 Applicable standards and reference documentation The drives documented in this manual have been developed as system peripherals to the highest standards of design and construction. The drives depends on host equipment to provide adequate power and environment for optimum performance and compliance with applicable industry and governmental regulations. Special attention must be given in the areas of safety, power distribution, shielding, audible noise control, and temperature regulation.
2.1.2 Electromagnetic compliance Seagate uses an independent laboratory to confirm compliance with the directives/standards for CE Marking and CTick Marking. The drive was tested in a representative system for typical applications and comply with the Electromagnetic Interference/Electromagnetic Susceptibility (EMI/EMS) for Class B products. The selected system represents the most popular characteristics for test platforms.
2.1.3 European Union Restriction of Hazardous Substances (RoHS) The European Union Restriction of Hazardous Substances (RoHS) Directive, restricts the presence of chemical substances, including Lead, Cadmium, Mercury, Hexavalent Chromium, PBB and PBDE, in electronic products, effective July 2006.

2.2 Reference documents SAS Interface Manual Seagate part number: 100293071 SCSI Commands Reference Manual Seagate part number: 100293068 Self-Encrypting Drives Reference Manual Seagate part number: 100515636 ANSI SAS Documents SFF-8223 SFF-8460 SFF-8470 SFF-8482 ANSI INCITS.xxx ISO/IEC 14776-xxx ISO/IEC 14776-xxx ISO/IEC 14776-xxx 2.
3.0 General description Constellation®.2 drives provide high performance, high capacity data storage for a variety of systems including engineering workstations, network servers, mainframes, and supercomputers. The Serial Attached SCSI interface is designed to meet next-generation computing demands for performance, scalability, flexibility and high-density storage requirements. Constellation®.
3.1 Standard features Constellation®.2 drives have the following standard features: • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • Perpendicular recording technology 1.5 / 3 / 6 Gb Serial Attached SCSI (SAS) interface Integrated dual port SAS controller supporting the SCSI protocol Support for SAS expanders and fanout adapters Firmware downloadable using the SAS interface 128 - deep task set (queue) Supports up to 32 initiators Jumperless configuration.
3.2 Media description The media used on the drive has a glass substrate coated with a thin film magnetic material, overcoated with a proprietary protective layer for improved durability and environmental protection. 3.3 • • • • • • Performance Programmable multi-segmentable cache buffer 600 MB/s maximum instantaneous data transfers. 7200 RPM spindle. Average latency = 4.
3.6 Programmable drive capacity Using the Mode Select command, the drive can change its capacity to something 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 will not change the capacity it is currently formatted to have.
4.0 Performance characteristics This section provides detailed information concerning performance-related characteristics and features of Constellation®.2 drives. 4.1 Internal drive characteristics Drive capacity Read/write data heads Bytes per track Bytes per surface Tracks per surface (total) Tracks per inch Peak bits per inch Areal density Internal data rate Disk rotation speed Avg rotational latency 4.
4.2.2 Format command execution time for 512-byte sectors (minutes) 1TB models 500GB models Maximum (with verify) 384 188 Maximum (without verify) 192 94 Execution time measured from receipt of the last byte of the Command Descriptor Block (CDB) to the request for a Status Byte Transfer to the Initiator (excluding connect/disconnect). When changing sector sizes, the format times shown above may need to be increased by 30 minutes. 4.2.
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.
4.5.1 Caching write data Write caching is a write operation by the drive that makes use of a drive buffer storage area where the data 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.
5.0 Reliability specifications The following reliability specifications assume correct host and drive operational interface, including all interface timings, power supply voltages, environmental requirements and drive mounting constraints. Seek error rate: Read Error Rates1 Recovered Data Unrecovered Data Miscorrected Data Interface error rate: Mean Time Between Failure (MTBF): Annualized Failure Rate (AFR): Preventive maintenance: 1.
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 errors in 108 seeks.
Caution. 5.2.4 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. 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.
Error rate is the number of errors per operation. The algorithm 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.
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. 2. Extended test 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.
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. 5.2.6.2.3 Short and extended tests DST has two testing options: 1. 2. short extended These testing options are described in the following two subsections. Each test consists of three segments: an electrical test segment, a servo test segment, and a read/verify scan segment.
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). 5.2.
6.0 Physical/electrical specifications This section provides information relating to the physical and electrical characteristics of the drive. 6.1 PowerChoiceTM power management Drives using the load/unload architecture provide programmable power management to tailor systems for performance and greater energy efficiency. The table below lists the supported PowerChoice modes. The further you go down in the table, the more power savings you get.
6.1.1 PowerChoice reporting methods PowerChoiceTM provides these reporting methods for tracking purposes: Request Sense command reports • Current power condition • Method of entry Note. Processing the Request Sense command does not impact the drive’s power save state.

General DC power requirement notes. 1. Minimum current loading for each supply voltage is not less than 1.7% of the maximum operating 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.
6.3.3 Current profiles The +12V (top) and +5V (bottom) current profiles for the Constellation drives are shown below. Figure 1. 1TB model current profiles Constellation.2 SAS Product Manual, Rev.

7.0 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).
Figure 10. Example of FIPS tamper evidence labels. Note. Image is for reference only, may not represent actual drive. Constellation.2 SAS Product Manual, Rev.
8.0 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 2.2. The Trusted Computing Group (TCG) is an organization sponsored and operated by companies in the computer, storage and digital communications industry.
8.2.2 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). 8.2.3 Default password When the drive is shipped from the factory, all passwords are set to the value of MSID.
8.6 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.
9.0 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 management and SAS system error considerations (errors in communications between the initiator and the drive).
Table 4 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.
9.4 Background Media Scan Background Media Scan (BMS) is a self-initiated media scan. BMS is defined in the T10 document SPC-4 available from the T10 committee. BMS performs sequential reads across the entire pack of the media while the drive is idle. In RAID arrays, BMS allows hot spare drives to be scanned for defects prior to being put into service by the host system. On regular duty drives, if the host system makes use of the BMS Log Page, it can avoid placing data in suspect locations on the media.
9.6 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.
9.8.1 Levels of PI There are 4 types of Protection Information. Type 0 - Describes a drive that is not formatted with PI information bytes. This allows for legacy support in non-PI systems. Type 1 - Provides support of PI protection using 10 and 16 byte commands. The RDPROTECT and 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.
10.0 Installation Constellation®.2 disk drive installation is a plug-and-play process. There are no jumpers, switches, or terminators 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 you need to mount the drive. Mount the drive to the carrier or tray provided by the host system using four M3 x 0.5 metric screws.
10.2 Cooling Cabinet cooling must be designed by the customer so that the ambient temperature immediately surrounding the drive will not exceed temperature conditions specified in Section 6.5.1, "Temperature." The rack, cabinet, or drawer environment for the drive must provide heat removal from the electronics and head and disk assembly (HDA). You should confirm that adequate heat removal is provided using the temperature measurement guidelines described in Section 6.5.1.
10.3 Drive mounting Mount the drive using the bottom or side mounting holes. If you mount the drive using the bottom 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).
11.0 Interface requirements This section partially describes the interface requirements as implemented on Constellation®.2 drives. Additional information is provided in the SAS Interface Manual (part number 100293071). 11.1 SAS features This section lists the SAS-specific features supported by Constellation®.2 drives. 11.1.1 task management functions Table 5 lists the SAS task management functions supported.
11.2 Dual port support Constellation.2 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 6Gb/s or the first port can run at 6Gb/s while the second port runs at 3Gb/s. The supported link rates are 1.5, 3.0, or 6.0Gb/s. Subject to buffer availability, the Constellation®.

before the drive achieves operating speed and 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.
