1.0 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.
2.0 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.
2.1.2 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.
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.

the extra capacity potential is useful, or whether their assurance of backward and forward compatibility takes precedence. 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.
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 600 8 165,000 1,361 225 1.49 - 2.37 15k 2.0 ST3450857FC ST3450757FC 450 6 165,000 1,361 225 1.49 - 2.37 15k 2.
Note. 4.2.3 There is no significant difference in the format time between SED and non-SED models of the same capacity. General performance characteristics Sustainable disc transfer rate*: Minimum 122 Mbytes/sec (typical) Maximum 204 Mbytes/sec (typical) Fibre Channel Interface maximum instantaneous transfer rate 400 Mbytes/sec* per port Logical block sizes Default is 512-byte data blocks Sector sizes variable to 512, 520, 524 and 528 bytes.
4.5 Note. Cache operation Refer to the Fibre Channel Interface Manual for more detail concerning the cache bits. Of the 16 Mbytes physical buffer space in the drive, approximately 13,000 kbytes can be used as a cache. The buffer is divided into logical segments from which data is read and to which data is written. The drive keeps track of the logical block addresses of the data stored in each segment of the buffer.
The Synchronize Cache command may be used to force the drive to write all cached write data to the medium. Upon completion of a Synchronize Cache command, all data received from previous write commands will have been written to the medium. Table 18 shows the mode default settings for the drive. 4.5.
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.
5.1.3 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.
5.2.6 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 text 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.
5.2.6.2.3 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.

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 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.
7.2.2 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). 7.2.3 Default password When the drive is shipped from the factory, all passwords are set to the value of MSID.
7.6 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.
8.0 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.
8.4 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.
8.7 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.
9.0 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 10.5 for additional information about this connector. Use the FC-AL interface to select drive ID and all option configurations for devices on the loop.
9.3 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 6.4.1. In some cases, forced airflow may be required to keep temperatures at or below the temperatures specified in Section 6.4.1. If forced air is necessary, possible air-flow patterns are shown in Figure 10.
9.4 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).

10.5.6 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.
10.5.8 Active LED Out The Active LED Out signal is driven by the drive as indicated in Table 25.
10.5.11 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.

10.5.12 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.
10.6.2 LED driver signals Fault and Active LED signals are located in the FC-SCA connector (J1). See Table 30 for the output characteristics of the LED drive signals.
