2.0 Scope This manual describes Seagate Technology® LLC, Constellation® ES.2 SAS (Serial Attached SCSI) disk drives. Constellation ES.2 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.
3.0 Applicable standards and reference documentation The drives documented in this manual have been developed as system peripherals to the highest standards of design and construction. The drives 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.
3.1.2 Electromagnetic compliance Seagate uses an independent laboratory to confirm compliance with the directives/standards for CE Marking and C-Tick Marking. The drive was tested in a representative system for typical applications. The selected system represents the most popular characteristics for test platforms.
3.1.3 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.

4.0 General description Constellation ES.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 ES.
4.1 Standard features Constellation ES.2 drives have the following standard features: • Perpendicular recording technology • 1.5 / 3.0 / 6.0 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.
4.4 • • • • • Reliability Annualized Failure Rate (AFR) of 0.73% Mean time between failures (MTBF) of 1,200,000 hours Balanced low mass rotary voice coil actuator Incorporates industry-standard Self-Monitoring Analysis and Reporting Technology (S.M.A.R.T.) 5-year warranty 4.5 Formatted capacities Standard OEM models are formatted to 512 bytes per block. The block size is selectable at format time and must be a multiple of 4 bytes.
5.0 Performance characteristics This section provides detailed information concerning performance-related characteristics and features of Constellation ES.2 drives. 5.1 Internal drive characteristics ST33000650SS ST33000651SS ST33000652SS 3 10 1,419,776 300,000 284,399 270,000 1,638,000 444 68.7 - 155 7200 4.
5.2.2 Format command execution time for 512-byte sectors (minutes) ST33000650SS ST33000651SS ST33000652SS Maximum (with verify) 827 Maximum (without verify) 402 Note. 5.2.3 There is approximately a 1.5 increase in time to format a SED drive versus a non-SED drive of the same capacity. General performance characteristics Minimum sector interleave 1 to 1 Data buffer to/from disk media (one 512-byte logical block)* 113 to 239 MB/s Sustained transfer rate 68.
5.4 Prefetch/multi-segmented cache control The drive provides a prefetch (read look-ahead) and multi-segmented cache control algorithms that in many cases can enhance system performance. Cache refers to the drive buffer storage space when it is used in cache operations. To select this feature, the host sends the Mode Select command with the proper values in the applicable bytes in page 08h.
5.5.1 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.
6.0 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.
6.1.3 Seek errors A seek error is defined as a failure of the drive to position the heads to the addressed track. After detecting an initial seek error, the drive automatically performs an error recovery process. If the error recovery process fails, a seek positioning error (Error code = 15h or 02h) will be reported with a Hardware error (04h) in the Sense Key. Recoverable seek errors are specified at Less than 10 errors in 108 seeks.
Caution. 6.2.4 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.
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 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.
6.2.6 Drive Self Test (DST) Drive Self Test (DST) is a technology designed to recognize drive fault conditions that qualify the drive as a failed unit. DST validates the functionality of the drive at a system level. There are two test coverage options implemented in DST: 1. Extended test 2. Short test The most thorough option is the extended test that performs various tests on the drive and scans every logical block address (LBA) of the drive.
6.2.6.2.3 Short and extended tests DST has two testing options: 1. short 2. extended These testing options are described in the following two subsections. Each test consists of three segments: an electrical test segment, a servo test segment, and a read/verify scan segment. Short test (Function Code: 001b) The purpose of the short test is to provide a time-limited test that tests as much of the drive as possible within 120 seconds.
6.2.7 Product warranty See Section 1.0 for warranty contact information. Shipping When transporting or shipping a drive, use only a Seagate-approved container. Keep your original box. Seagate approved containers are easily identified by the Seagate Approved Package label. Shipping a drive in a non-approved container voids the drive warranty. Seagate repair centers may refuse receipt of components improperly packaged or obviously damaged in transit.
7.0 Physical/electrical specifications This section provides information relating to the physical and electrical characteristics of the drive. 7.1 PowerChoiceTM power management Drives using the load/unload architecture provide programmable power management to tailor systems for performance and greater energy efficiency. The table below lists the supported PowerChoice modes. The further you go down in the table, the more power savings you get.
7.1.1 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.

components should never be exposed to condensing water on the surface of the printed circuit board assembly (PCBA) or exposed to an ambient relative humidity greater than 95%. Materials used in cabinet fabrication, such as vulcanized rubber, that can outgas corrosive compounds should be minimized or eliminated. The useful life of any electronic equipment may be extended by replacing materials near circuitry with sulfide-free alternatives. 7.5.8 Electromagnetic susceptibility See Section 3.1.1.1.

8.0 About FIPS The Federal Information Processing Standard (FIPS) Publication 140-2, FIPS PUB 140-2, is a U.S. government computer security standard used to accredit cryptographic modules. It is titled “Security Requirements for Cryptographic Modules”. The initial publication was on May 25, 2001 and was last updated December 3, 2002.
9.0 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 3.2. The Trusted Computing Group (TCG) is an organization sponsored and operated by companies in the computer, storage and digital communications industry.
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 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. 9.
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 signed and authenticated. 3.
10.0 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 3 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.
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-initiated media scanning activity. Since the background scan functions are only done during idle periods, BMS causes a negligible impact to system performance.
10.8 Protection Information (PI) Protection Information is intended as a standardized approach to system level LRC traditionally provided by systems using 520 byte formatted LBAs. Drives formatted with PI information provide the same, common LBA count (i.e. same capacity point) as non-PI formatted drives. Sequential performance of a PI drive will be reduced by approximately 1.
11.0 Installation Constellation ES.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.
11.2 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 7.5.1, "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 7.5.1.
11.3 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).
12.0 Interface requirements This section partially describes the interface requirements as implemented on Constellation ES.2 drives. Additional information is provided in the SAS Interface Manual (part number 100293071). 12.1 SAS features This section lists the SAS-specific features supported by Constellation ES.2 drives. 12.1.1 task management functions Table 4 lists the SAS task management functions supported.
12.2 Dual port support Constellation ES.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 6.0 Gb/s. Subject to buffer availability, the Constellation ES.

12.3.1 Inquiry data Table 7 lists the Inquiry command data that the drive should return to the initiator per the format given in the SAS Interface Manual. Table 7: Constellation ES.
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.

Part numbers for SAS connectors will be provided in a future revision of this publication when production parts are available from major connector manufacturers. The SAS device connector is illustrated in Figures 11 and 12. 12.4.
12.4.6 SAS transmitters and receivers A typical SAS differential copper transmitter and receiver pair is shown in Figure 13. The receiver is AC coupling to eliminate ground shift noise. .01 TX Differential Transfer Medium Transmitter 100 TY Figure 13. SAS transmitters and receivers 12.4.7 Power RX Receiver 100 .01 RY 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 Ready LED Out signal is designed to pull down the cathode of an LED. The anode is attached to the proper +3.3 volt supply through an appropriate current limiting resistor. The LED and the current limiting resistor are external to the drive. See Table 13 for the output characteristics of the LED drive signals. Table 13: LED drive signal State Test condition Output voltage LED off, high 0 V ≤VOH ≤3.6 V -100 µA < IOH < 100 µA LED on, low IOL = 15 mA 0 ≤VOL ≤0.225 V 12.5.
