2.0 Scope This manual describes Seagate Technology® LLC, Cheetah® 15K.7 FC (Fibre Channel) disc drives. Cheetah 15K.7 FC drives support the Fibre Channel Arbitrated Loop and SCSI Fibre Channel Protocol specifications to the extent described in this manual. The Fibre Channel Interface Manual (part number 100293070) describes the general Fibre Channel Arbitrated Loop characteristics of this and other Seagate Fibre Channel drives.
3.0 Applicable standards and reference documentation The drive has been developed as a system peripheral to the highest standards of design and construction. The drive depends upon its host equipment to provide adequate power and environment in order to achieve 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.
3.3 Reference documents ANSI Fibre Channel Documents X3.230-1994 X3.297.1997 X3.303.1998 X3.272-1996 X3.
4.0 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.
4.1 Standard features Cheetah 15K.
4.2 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. 4.3 • • • • • • • Performance Programmable multi-segmentable cache buffer 400 Mbytes/sec maximum instantaneous data transfers per port 15k RPM spindle; average latency = 2.
4.5.1 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.
5.0 Performance characteristics This section provides detailed information concerning performance-related characteristics and features of Cheetah 15K.7 FC drives. 5.1 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.
5.2.2 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. 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.
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 Rates Recovered Data Unrecovered Data Miscorrected Data Interface error rate: Annualized Failure Rate (AFR): Preventive maintenance: 6.
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.
present, loop operation may continue. If the bypass circuit is not present, loop operation will be halted while the self test of the FC interface runs. When the self test completes successfully, the control line to the bypass circuit is disabled and the drive enters the FC-AL Initializing state. The receiver on the next device in the loop must synchronize to output of the newly inserted drive. If the self-test fails, the control line to the bypass circuit remains in the Enable Bypass state. Note.
Determining rate S.M.A.R.T. monitors the rate at which errors occur and signals a predictive failure if the rate of degraded errors increases to an unacceptable level. To determine rate, error events are logged and compared to the number of total operations for a given attribute. The interval defines the number of operations over which to measure the rate. The counter that keeps track of the current number of operations is referred to as the Interval Counter. S.M.A.R.T. measures error rates.
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.

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 3.3. The Trusted Computing Group (TCG) is an organization sponsored and operated by companies in the computer, storage and digital communications industry.
9.2.2 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). 9.2.3 Default password When the drive is shipped from the factory, all passwords are set to the value of MSID.
9.6 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.
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 FC system error considerations (errors in communications between the initiator and the drive).
read or re-write attempt. The maximum level used by the drive in LBA recovery is determined by the read and write retry counts. Table 5 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.
Table 5: Read and write retry count maximum recovery times [1] Read retry count Maximum recovery time per LBA (cumulative, msec) Write retry count Maximum recovery time per LBA (cumulative, msec) 0 51.87 0 23.94 1 59.85 1 35.91 2 203.49 2 39.9 3 231.42 3 51.87 4 295.26 4 79.8 5 327.18 5 (default) 107.73 6 359.10 7 446.88 8 538.65 9 570.57 10 598.50 11 (default) 1,534.97 [1] These values are subject to change.
10.4 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.
10.7 Idle Read After Write Idle Read After Write (IRAW) utilizes idle time to verify the integrity of recently written data. During idle periods, no active system requests, the drive reads recently written data from the media and compares it to valid write command data resident in the drives data buffer. Any sectors that fail the comparison result in the invocation of a rewrite and auto-reallocation process. The process attempts to rewrite the data to the original location.
11.0 Installation Cheetah 15K.7 FC disc 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 (FCSCA)—no cables are required. See Section 12.5 for additional information about this connector. Use the FC-AL interface to select drive ID and all option configurations for devices on the loop.
11.3 Cooling The host enclosure must dissipate heat from the drive. You should confirm that the host enclosure is designed to ensure that the drive operates within the temperature measurement guidelines described in Section 7.4.1. In some cases, forced airflow may be required to keep temperatures at or below the temperatures specified in Section 7.4.1. If forced air is necessary, possible air-flow patterns are shown in Figure 11.
11.4 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).

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.

12.5 FC-AL physical interface Figure 12 shows the location of the J1 Fibre Channel single connection attachment (FC-SCA). Figure 14 provides the dimensions of the FC-SCA connector. Details of the physical, electrical, and logical characteristics are provided within this section. The operational aspects of Seagate’s Fibre Channel drives are provided in the Fibre Channel Interface Manual.. J1 interface connector Figure 12. Physical interface 12.5.

12.5.6 Power Power is supplied through the FC-SCA with support for +5 volts and +12 volts. All of the voltage pins in the drive connector are the same length. Four 12 volt pins provide +12 volt power to the drive. The current return for the +12 volt power supply is through the common ground pins. The supply current and return current must be distributed as evenly as possible among the pins. The maximum current typically occurs while the drive motor is starting.
12.5.8 Active LED Out The Active LED Out signal is driven by the drive as indicated in Table 25.
12.5.11 SEL_6 through SEL_0 ID lines The SEL_6 through SEL_0 ID lines determine drive address, and, optionally, for an Enclosure Services Interface. When the Parallel ESI line is high, the enclosure backpanel must provide address information on the SEL line. Refer to table 27 for a mapping of SEL to FC-AL physical addresses (AL_PA). You can think of the SEL lines as the equivalent of a backpanel logic plug. The drives does not provide pull up resistors on these lines.

12.5.12 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.
