4.0 PERFORMANCE CHARACTERISTICS This section provides detailed information concerning performance-related characteristics and features of Constellation ES.1 drives. 4.1 INTERNAL DRIVE CHARACTERISTICS ST2000NM0001 ST2000NM0021 ST2000NM0041 2TB 8 1,012,608 250,000 248,600 237,000 1,523,000 324 95 - 212 7200 4.
4.2.3 General performance characteristics Minimum sector interleave Data buffer to/from disk media (one 512-byte logical block)* Sustained transfer rate SAS Interface maximum instantaneous transfer rate 1 to 1 95 to 212 MB/s 62 to 152 MB/s 600MB/s* per port (dual port = 1200MB/s*) Logical block sizes 512 (default), 520 or 528.
The following is a simplified description of the prefetch/cache operation: Case A—read command is received and all of the requested logical blocks are already in the cache: 1. Drive transfers the requested logical blocks to the initiator. Case B—A Read command requests data, and at least one requested logical block is not in any segment of the cache: 1.
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 You can enhance the reliability of Constellation ES.1 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 AFR of 0.
5.2.4 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 you 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.
5.2.5 Thermal monitor Constellation ES.1 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. 3. 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.
5.2.6.2 Implementation This section provides all of the information necessary to implement the DST function on this drive. 5.2.6.2.1 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.
5.2.6.2.5 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.

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).
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.
8.5 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.
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 5 Read and write retry count maximum recovery times Read retry count 0 1 2 3 4 5 6 7 8 9 10 11 12 (default) Maximum recovery time per LBA (cumulative, ms) 108.29 124.95 424.83 458.15 483.14 590.16 644.92 711.56 898.54 1049.49 1116.13 1174.44 2311.47 Write retry count 0 1 2 3 4 5 (default) Maximum recovery time per LBA (cumulative, ms) 23.94 35.91 55.86 67.83 119.79 147.72 Setting these retry counts to a value below the default setting could result in degradation of the unrecovered error rate.
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.
10.0 INSTALLATION Constellation ES.1 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.
If forced air is determined to be necessary, possible air-flow patterns are shown in Figure 15. 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 6.5.1 are met. b Note. l b b b Note. Figure 15. 10.3 l Air flow DRIVE MOUNTING Mount the drive using the bottom or side mounting holes.

11.4.2 Physical characteristics This section defines physical interface connector. 11.4.3 Connector requirements Contact your preferred connector manufacturer for mating part information. 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 17 and 18. 11.4.
11.4.6 SAS transmitters and receivers A typical SAS differential copper transmitter and receiver pair is shown in Figure 19. The receiver is AC coupling to eliminate ground shift noise. 1 X X l 1 1 1 Figure 19. 11.4.7 SAS transmitters and receivers Power 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 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 17 for the output characteristics of the LED drive signals. Table 17 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.
