39 devices of the direct access class that are attached to the system
43 The direct access class includes disk, magneto-optical,
44 and solid-state devices.
54 Many direct access devices are equipped with read and/or write caches.
61 The read cache is used to store data from device-initiated read ahead
71 The write cache can greatly decrease the latency of write operations
72 and allows the device to reorganize writes to increase efficiency and
76 lose power while its cache contains uncommitted write operations, these
78 The effect of a loss of write transactions on
79 a file system is non-deterministic and can cause corruption.
81 devices age write transactions to limit vulnerability to a few transactions
82 recently reported as complete, but it is none-the-less recommended that
83 systems with write cache enabled devices reside on an Uninterruptible
