2.3 REFERENCE DOCUMENTS ANSI Fibre Channel Documents X3.230-1994 X3.297.1997 X3.303.1998 X3.272-1996 X3.
3.0 GENERAL DESCRIPTION Cheetah 15K.7 FC drives provide high performance, high capacity data storage for a variety of systems including engineering workstations, network servers, mainframes, and supercomputers. Cheetah 15K.7 FC drives support 4-Gbit Fibre Channel. Cheetah 15K.
3.1 STANDARD FEATURES Cheetah 15K.
3.2 MEDIA DESCRIPTION The media used on the drive has an aluminum 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 400 Mbytes/sec maximum instantaneous data transfers per port 15k RPM spindle; average latency = 2.
3.5.1 Programmable drive capacity Using the Mode Select command, the drive can change its capacity to something less than maximum. See the Mode Select Parameter List table in the SCSI Commands Reference Manual. Refer to the Parameter list block descriptor number of blocks field. A value of zero in the number of blocks field indicates that the drive shall 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 Cheetah 15K.7 FC drives. 4.1 INTERNAL DRIVE CHARACTERISTICS Drive capacity Read/write data heads Tracks per inch Peak bits per inch Areal Density Internal data rate disk rotation speed Avg rotational latency ST3600057FC ST3600957FC ST3600857FC 600 8 165,000 1,361 225 1.49 - 2.37 15k 2.0 ST3450857FC ST3450757FC ST3450657FC 450 6 165,000 1,361 225 1.49 - 2.37 15k 2.
4.2.2 Format command execution time (minutes) When changing sector sizes, the format times shown below may need to be increased by 30 minutes. ST3600057FC ST3450857FC ST3300657FC Maximum (with verify) 119 88 58 Maximum (without verify) 60 44 29 Note. There is approximately a 1.5 increase in time to format a SED drive versus a non-SED drive of the same capacity. 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 Rates Recovered Data Unrecovered Data Miscorrected Data Interface error rate: Annualized Failure Rate (AFR): Preventive maintenance: 5.
5.2 RELIABILITY AND SERVICE You can enhance the reliability of Constellation ES.3 SAS 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 Failures (MTBF) These drives shall achieve an AFR of 0.
Controlling S.M.A.R.T. The operating mode of S.M.A.R.T. is controlled by the DEXCPT and PERF bits on the Informational Exceptions Control mode page (1Ch). Use the DEXCPT bit to enable or disable the S.M.A.R.T. feature. Setting the DEXCPT bit disables all S.M.A.R.T. functions. When enabled, S.M.A.R.T. collects on-line data as the drive performs normal read and write operations. When the PERF bit is set, the drive is considered to be in “On-line Mode Only” and will not perform off-line functions.
5.2.5 Thermal monitor Cheetah 15K.7 FC 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.
5.2.6.1 DST failure definition The drive will present a “diagnostic failed” condition through the self-tests results value of the diagnostic log page if a functional failure is encountered during DST. The channel and servo parameters are not modified to test the drive more stringently, and the number of retries are not reduced. All retries and recovery processes are enabled during the test.
The anticipated length of the Extended test is reported through the Control Mode page. 5.2.6.2.4 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.
6.0 PHYSICAL/ELECTRICAL SPECIFICATIONS This section provides information relating to the physical and electrical characteristics of the drive. 6.1 AC POWER REQUIREMENTS None. 6.2 DC POWER REQUIREMENTS The voltage and current requirements for a single drive are shown below.

6.3 POWER DISSIPATION 600GB model Typical power dissipation under idle conditions in 4 Gbit operation is 11.58 watts (39.52 BTUs per hour). To obtain operating power for typical random read 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. Figure 4.
0GB models Typical power dissipation under idle conditions in 4 Gbit operation is 9.06 watts (30.92 BTUs per hour). To obtain operating power for typical random read 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. Figure 6.
6.4 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). Maximum wet bulb temperature is 82°F (28°C). 6.4.1 Temperature a. Operating The maximum allowable continuous or sustained HDA case temperature for the rated Annualized Failure Rate (AFR) is 122°F (50°C). The maximum allowable HDA case temperature is 60°C.
6.4.4 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 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 2.3. The Trusted Computing Group (TCG) is an organization sponsored and operated by companies in the computer, storage and digital communications industry.
8.4 DRIVE LOCKING In addition to changing the passwords, as described in Section 8.2.3, the owner should also set the data access controls for the individual bands. The variable "LockOnReset" should be set to "PowerCycle" to ensure that the data bands will be locked if power is lost. This scenario occurs if the drive is removed from its cabinet. The drive will not honor any data read or write requests until the bands have been unlocked.
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 FC system error considerations (errors in communications between the initiator and the drive).

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.
10.0 INSTALLATION Cheetah 15K.7 FC disk drive installation is a plug-and-play process. There are no jumpers, switches, or terminators on the drive. Simply plug the drive into the host’s 40-pin Fibre Channel backpanel connector (FC-SCA)—no cables are required. See Section 11.5 for additional information about this connector. Use the FC-AL interface to select drive ID and all option configurations for devices on the loop.
10.4 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).

11.5.12 Device control codes The drive inputs a Device Control Code on the DEV_CTRL_CODE lines at power up to determine the link rate on the Fibre Channel ports. Both ports run at the same rate. If the backpanel does not connect to these lines, the drive has 10K ohm pull up resistors that default the device control code to 7 (1.0625 GHz). Table lists the supported codes. Table 28 Device control code values 2 (PIN 17) 1 (PIN 18) 0 (PIN 39) DEFINITION 0 0 0 Reserved for power failure warning.
