Hawk 4XL Product Manual, Rev. A Notes for Section 4.2. Execution time is measured from receipt of the last Byte of the Command Descriptor Block (CDB) to the request for a Status Byte Transfer to the Initiator (excluding connect/disconnect). Maximum times are specified over the worst case conditions of temperature, voltage margins and drive orientation. -
Page 22: Caching Write Data
Hawk 4XL Product Manual, Rev. A “miss”, all data transfers to the host are in accordance with “buffer-full” ratio rules. On a cache “hit” the drive ignores the “buffer-full” ratio rules. See explanations associated with Mode page 02h (disconnect/reconnect control) in the SCSI Interface Product Manual (part number 77738479). The following is a simplified description of a read operation with cache operation enabled: Case A - A Read command is received and the first logical block (LB) is already in cache: 1. - Page 23 Hawk 4XL Product Manual, Rev. A system performance. The max prefetch field (bytes 8 and 9) limits the amount of prefetch. The drive does not use the prefetch “ceiling” field (bytes 10 and 11). During a prefetch operation, the drive crosses a cylinder boundary to fetch more data only if the Discontinuity (DISC) bit is set to one in bit 4 of byte 2 of Mode parameters page 08h.
