3.0 General description Enterprise Capacity 3.5 HDD v5 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. Enterprise Capacity 3.
3.1 Standard features Enterprise Capacity 3.5 HDD v5 drives have the following standard features: • 128 - deep task set (queue) • 256MB data buffer (see Section 4.4). • 3.0 / 6.0/12.0 Gb Serial Attached SCSI (SAS) interface • Drive Self Test (DST) • Embedded servo design • Firmware downloadable using the SAS interface • Flawed logical block reallocation at format time • Idle Read After Write (IRAW) • Industry standard SFF 3.
3.5 Formatted capacities Standard OEM models are formatted to 512 bytes per block for 512 emulation and native drives and 4096 bytes per block for 4096 native drives. The block size is selectable at format time. Supported block sizes are 512, 520, 524, and 528 for 512 emulation and native drives and 4096, 4160, 4192, and 4224 for 4096 native drives.
4.0 Performance characteristics This section provides detailed information concerning performance-related characteristics and features of Enterprise Capacity 3.5 HDD v5 drives. 4.1 Internal drive characteristics Drive capacity Read/write data heads Bytes/track Bytes/surface Tracks/surface (total) Tracks/in Peak bits/in Areal density Internal data rate Disk rotation speed Avg rotational latency 4.1.1 8TB models 12 2,179,072 1,300,000 33,900 375,000 2,226,000 802 2546 7200 4.
4.2 Start/stop time The drive accepts the commands listed in the SAS Interface Manual less than 3 seconds after DC power has been 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 30 seconds (excluding the error recovery procedure).
4.4.1 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.
5.2 Reliability and service Users can enhance the reliability of Enterprise Capacity 3.5 HDD v5 disk drives by ensuring that the drive receives adequate cooling. Section 6.0 provides temperature measurements and other information that may be used to enhance the service life of the drive. Section 10.2 provides recommended air-flow information. 5.2.1 Annualized Failure Rate (AFR) and Mean Time Between Failure (MTBF) The production disk drive shall achieve an annualized failure-rate of 0.
5.2.3 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 users to back up the data before an actual failure occurs. Note The drive’s firmware monitors specific attributes for degradation over time but can’t predict instantaneous drive failures.
5.2.4 Thermal monitor Enterprise Capacity 3.5 HDD v5 drives implement a temperature warning system which: 1. Signals the host if the temperature exceeds a value which would threaten the drive. 2. Saves a S.M.A.R.T. data frame on the drive which exceeds the threatening temperature value. A temperature sensor monitors the drive temperature and issues a warning over the interface when the temperature exceeds a set threshold.
5.2.5.2 Implementation This section provides all of the information necessary to implement the DST function on this drive. 5.2.5.2.1 State of the drive prior to testing The drive must be in a ready state before issuing the Send Diagnostic command. There are multiple reasons why a drive may not be ready, some of which are valid conditions, and not errors. For example, a drive may be in process of doing a format, or another DST.
5.2.5.2.4 Log page entries When the drive begins DST, it creates a new entry in the Self-test Results Log page. The new entry is created by inserting a new self-test parameter block at the 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.
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 down the user goes in the table, the more power savings the user gets.
6.2 AC power requirements None. 6.3 DC power requirements The voltage and current requirements for a single drive are shown below. Values indicated apply at the drive connector. 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.
[4] [5] [6] This condition occurs after OOB and Speed Negotiation completes but before the drive has received the Notify Spinup primitive. See paragraph 6.3.1, "Conducted noise immunity." Specified voltage tolerance includes ripple, noise, and transient response. During idle, the drive heads are relocated every 60 seconds to a random location within the band from three-quarters to maximum track. General DC power requirement notes. 1. 2. 3. 4. 5.
6.3.3 Current profiles The +12V (top) and +5V (bottom) current profiles for the Enterprise Capacity 3.5 HDD drives are shown below. Figure 1. Note 8TB model current profiles. All times and currents are typical. See Table 3 for maximum current requirements. Seagate Enterprise Capacity 3.5 HDD v5 SAS Product Manual, Rev.
6.4 Power dissipation 8TB and 6TB models in 12Gb operation Please refer to Table 3 for power dissipation numbers. To obtain operating power for typical random read operations, refer to the following I/O rate curve (see Figure 2.). Locate the typical I/O rate for a drive in the 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 2.
6.5 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). Note 6.5.1 To maintain optimal performance drives should be run at nominal drive temperatures and humidity Temperature a.
6.5.4 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.

7.0 About self-encrypting drives Self-encrypting drives (SEDs) offer encryption and security services for the protection of stored data, commonly known as “protection of data at rest.” These drives are compliant with the Trusted Computing Group (TCG) Enterprise Storage Specifications as detailed in Section 2.4. The Trusted Computing Group (TCG) is an organization sponsored and operated by companies in the computer, storage and digital communications industry.
7.5 Data bands When shipped from the factory, the drive is configured with a single data band called Band 0 (also known as the Global Data Band) which comprises LBA 0 through LBA max. The host may allocate Band1 by specifying a start LBA and an LBA range. The real estate for this band is taken from the Global Band.
8.0 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).
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).

Valid range setting is 1-20. e.g.
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.
9.8 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.
10.0 Installation Enterprise Capacity 3.5 HDD v5 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 users need to mount the drive.
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). Users 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 mounting the drive using the bottom holes, ensure the drive is not physically distorted by attempting to mount it on a stiff, non-flat surface. The allowable mounting surface stiffness is 80 lb/in (14.0 N/mm).
