Cheetah 15K.3 FC Product Manual, Rev. D 11 Of the 8,192 kbytes physical buffer space in the drive, approximately 7,500 kbytes can be used as a cache. The buffer can be divided into logical segments (using Mode Select Page 08h, byte 13) 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.
12 Cheetah 15K.3 FC Product Manual, Rev. D was written there at the beginning of the operation; however, the drive does not overwrite data that has not yet been written to the medium. If write caching is enabled (WCE=1), then the drive may return Good status on a write command after the data has been transferred into the cache, but before the data has been written to the medium.
Cheetah 15K.3 FC Product Manual, Rev.

Cheetah 15K.3 FC Product Manual, Rev. D 7.0 33 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).
34 Cheetah 15K.3 FC Product Manual, Rev. D 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 15K.3 FC Product Manual, Rev. D 8.0 35 Installation Cheetah 15K.3 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 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.
