2.0 Scope This manual describes Seagate Technology® LLC, Pulsar® XT.2 SAS (Serial Attached SCSI) drives. Pulsar XT.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. The Self-Encrypting Drive Reference Manual, part number 100515636, describes the interface, general operation, and security features available on Self-Encrypting Drive models.
3.0 Applicable standards and reference documentation The drives documented in this manual have been developed as system peripherals to the highest standards of design and construction. The drives depend on host equipment to provide adequate power and environment for optimum performance and compliance with applicable industry and governmental regulations. Special attention must be given in the areas 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.
3.1.4 China Restriction of Hazardous Substances (RoHS) Directive This product has an Environmental Protection Use Period (EPUP) of 20 years. The following table contains information mandated by China's "Marking Requirements for Control of Pollution Caused by Electronic Information Products" Standard. "O" indicates the hazardous and toxic substance content of the part (at the homogenous material level) is lower than the threshold defined by the China RoHS MCV Standard.
4.0 General description Pulsar XT.2 drives provide high performance, high capacity data storage for a variety of systems with a Serial Attached SCSI (SAS) interface. The Serial Attached SCSI interface is designed to meet next-generation computing demands for performance, scalability, flexibility and high-density storage requirements. Pulsar XT.
• • • • • • • Automatic data encryption/decryption Controlled access Random number generator Drive locking 16 independent data bands Cryptographic erase of user data for a drive that will be repurposed or scrapped Authenticated firmware download 4.2 Media description The media used on the drive consists of Single Layer Cell (SLC) NAND Flash for improved reliability and performance. 4.3 • • • • Note. 4.
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. Users having the necessary equipment may modify the data block size before issuing a FORMAT UNIT command and obtain different formatted capacities than those listed.
4.8 Thin Provisioning 4.8.1 Logical Block Provisioning The drive is designed with a feature called Thin Provisioning. Thin Provisioning is a technique which does not require Logical Blocks to be associated to Physical Blocks on the storage medium until such a time as needed. The use of Thin Provisioning is a major factor in SSD products because it reduces the amount of wear leveling and garbage collection that must be performed. The result is an increase in the products endurance.
When a region of LBA's are erased via cryptographic erase, as part of the erase, the drive shall unmap those LBAs. If the host attempts to access an unmapped or trimmed LBA, the drive shall return scrambled data. For a given LBA, the data shall be identical from access to access, until that LBA is either updated with actual data from the host or that LBA is cryptographically erased. The drive shall report a value of '0' in the LBPRZ field returned in the READ CAPACITY (16) parameter data.
5.0 Performance characteristics This section provides detailed information concerning performance-related characteristics and features of Pulsar XT.2 drives. Note. Data provided is based on format at 512-bytes. 5.1 Internal drive characteristics Drive capacity Flash Memory Type Emulated LBA Size Native Programmable Page Size Default Transfer Alignment Offset 5.
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.
Due to the nature of Flash memory technologies there are many factors that can result in values different than those stated in this specification. Some discrepancies can be caused by bandwidth limitations in the host adapter, operating system, or driver limitations. It is not the intent of this manual to cover all possible causes of performance discrepancies.
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.
6.1.1 Unrecoverable Errors An unrecoverable data error is defined as 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 will be reported. Multiple unrecoverable data errors resulting from the same cause are treated as 1 error. 6.1.
6.2.5 Data Retention Data Retention is another major characteristic of SSD's 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. 6.2.6 Lifetime Endurance Management As stated in Section 6.
the static electricity from the drive carrier prior to inserting it into the system. 6.3.4 S.M.A.R.T. S.M.A.R.T. is an acronym for Self-Monitoring Analysis and Reporting Technology. This technology is intended to recognize conditions that indicate imminent drive failure and is designed to provide sufficient warning of a failure to allow administrators 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 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.
6.3.6 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.
6.3.6.2.3 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 two segments: an electrical 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.
6.3.
7.0 Physical/electrical specifications This section provides information relating to the physical and electrical characteristics of the drive. 7.1 Power specifications The drive receives DC power (+5V and +12V) through the standard SAS interface. 7.1.1 Power consumption Power requirements for the drives are listed in the tables beginning on page 23.

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.

7.4 Power dissipation 400GB models in 6Gb operation Typical power dissipation under idle conditions in 6Gb operation is 5.92 watts 20.20 BTUs per hour). To obtain operating power for typical random write operations, refer to the following I/O rate curve (see Figure 4). Locate the typical I/O rate for a drive in your system on the horizontal axis and read the corresponding +5 volt current, +12 volt current, and total watts on the vertical axis. To calculate BTUs per hour, multiply watts by 3.4123.
100GB models in 6Gb operation Typical power dissipation under idle conditions in 6Gb operation is 4.04 watts 13.79 BTUs per hour). To obtain operating power for typical random write operations, refer to the following I/O rate curve (see Figure 6). Locate the typical I/O rate for a drive in your system on the horizontal axis and read the corresponding +5 volt current, +12 volt current, and total watts on the vertical axis. To calculate BTUs per hour, multiply watts by 3.4123. Figure 6.

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 3.2. 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).
The DIE field contains the die number within channel. The BLOCK field contains the block number within the die. The VENDOR UNIQUE field may contain vendor unique information. 9.2 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. 9.
9.6 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.
10.0 Installation Pulsar XT.2 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.
10.2 Cooling Cabinet cooling must be designed by the customer so that the temperature of the drive will not exceed temperature conditions specified in Section 7.5.1, "Temperature." 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 7.5.1.
10.3 Drive mounting Mount the drive using the bottom or side mounting holes. If mounting 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 Pulsar XT.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 Pulsar XT.2 drives. 11.1.1 Task management functions Table 12 lists the SAS task management functions supported.
11.2 Dual port support Pulsar XT.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 Pulsar XT.

11.3.1 INQUIRY data Table 15 lists the INQUIRY command data that the drive should return to the initiator per the format given in the SAS Interface Manual. Table 15: Pulsar XT.
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.

The SAS device connector is illustrated in Figures 15 and 16. 11.4.
11.4.6 SAS transmitters and receivers A typical SAS differential copper transmitter and receiver pair is shown in Figure 17. The receiver is AC coupling to eliminate ground shift noise. .01 TX RX Differential Transfer Medium Transmitter 100 TY Figure 17. SAS transmitters and receivers 11.4.7 Power Receiver 100 RY .01 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 23 for the output characteristics of the LED drive signals. Table 23: 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 11.5.
