C General performance characteristics ST39102FC Minimum sector interleave 1 to 1 Data buffer to/from disc media (one 512-byte logical block)* Minimum Average Maximum 19.0 MBytes/sec 23.9 MBytes/sec 28.4 MBytes/sec Fibre Channel Interface maximum instantaneous transfer rate 106 Mbytes/sec*per port (dual port = 212 Mbytes/sec*) Logical block sizes Default is 512-byte data blocks Variable 512 to 4,096 bytes per sector in multiples of 4 bytes.
Cheetah 9LP FC Product Manual, Rev. C 11 Of the 1,024 Kbytes physical buffer space in the drive, 967.5 Kbytes can be used as a cache. The cache can be 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 cache.
12 Cheetah 9LP FC Product Manual, Rev. C stored in the cache from a previous read or write command. If there are, the respective cache segments are cleared. The new data is cached for subsequent read commands. If a 10-byte CDB Write command (2Ah) is issued with the data page out (DPO) bit set to 1, no write data is cached, but the cache segments are still checked and cleared, if need be, for any logical blocks that are being written.
Cheetah 9LP FC Product Manual, Rev. C 5.0 13 Reliability specifications The following reliability specifications assume correct host and drive operational interface, including all interface timings, power supply voltages, and environmental requirements. Seek error rate: Recoverable media error rate (using OEM default settings): Unrecovered media data: Miscorrected media data: Interface error rate: MTBF: Service life: Preventive maintenance: 5.
14 5.2 Cheetah 9LP FC Product Manual, Rev. C 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.
Cheetah 9LP FC Product Manual, Rev. C 5.3 15 Reliability and service The reliability of Cheetah 9LP FC disc drives can be enhanced by ensuring that the drive receives adequate cooling. This section provides recommended air-flow information, temperature measurements, and other information, which you can use to enhance the service life of the drive. 5.3.
16 Cheetah 9LP FC Product Manual, Rev. C Failure rate is calculated as follows: • • • • No system-induced failures counted PPM targets include 30% no defect found and handling failures Based on 1,000,000 MTBF and 720 POH per month Month 1’s rate includes a 300 PPM installation failure 5.3.3 Preventive maintenance No routine scheduled preventive maintenance is required. 5.3.4 Service life The drive has a useful service life of five years.
Cheetah 9LP FC Product Manual, Rev. C 17 The disc drive defaults to the FC-AL Monitoring state, Pass-through state, when it is powered-on by switching the power or hot plugged. The control line to an optional port bypass circuit (external to the drive), defaults to the Enable Bypass state. If the bypass circuit is present, the next device in the loop will continue to receive the output of the previous device to the newly inserted device.
Cheetah 9LP FC Product Manual, Rev. C 6.0 19 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. On-board +3.3V current is derived entirely from the +5V supply. Values indicated apply at the drive connector. Parameters, others than spindle start, are measured after a 10-minute warm-up.
20 Cheetah 9LP FC Product Manual, Rev. C 6.2.1 Conducted noise immunity Noise is specified as a periodic and random distribution of frequencies covering a band from DC to 10 MHz. Maximum allowed noise values given below are peak-to-peak measurements and apply at the drive power connector. 0 to 100 kHz 100 kHz to 10 MHz 6.2.2 +5V +12V (with spindle motor not running) 150mV 100mV 150mV 100mV Power sequencing The drive does not require power sequencing.
Cheetah 9LP FC Product Manual, Rev. C 6.4 21 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 MTBF specification for the drive is based on operating at a local ambient temperature of 86°F (30°C).
22 Cheetah 9LP FC Product Manual, Rev. C mal levels may promote degraded operational performance during the abnormal shock period. Specified operational performance will continue when normal operating shock levels resume. Shock may be applied in the X, Y, or Z axis. Shock is not to be repeated more than two times per second. c. Non-operating The limits of non-operating shock apply to all conditions of handling and transportation. This includes both isolated drives and integrated drives.
Cheetah 9LP FC Product Manual, Rev. C 6.5 23 Electromagnetic susceptibility As a component part, the drive is not required to meet any susceptibility performance requirements. It is the responsibility of the system integrator to perform tests required to ensure that equipment operating in the same system as the drive does not adversely affect the performance of the drive. See paragraph 6.2, “DC power requirements.” 6.
Cheetah 9LP FC Product Manual, Rev. C 7.0 25 Defect and error management The drive, as delivered, complies with this product manual. The read error rates and specified storage capacities are not dependent upon use of defect management routines by the host (initiator). Defect and error management in the SCSI protocol involves the drive internal defect/error management and FC-AL system error considerations (errors in communications between the initiator and the drive).
26 Cheetah 9LP FC Product Manual, Rev. C When the RC bit is one, reallocations are disabled even if the ARRE or AWRE bits are one. The drive will still perform data recovery actions within the limits defined by the Read Retry Count, Write Retry Count, and Recovery Time Limit parameters. However, the drive does not report any unrecovered errors.
Cheetah 9LP FC Product Manual, Rev. C 8.0 27 Installation Cheetah 9LP 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 (FC-SCA) — no cables are required. See Section 9.5 for additional information about this connector. Use the FC-AL interface to select drive ID and all option configurations for devices on the loop.
