T
Target ID
A target ID is the SCSI ID of a device attached to the disk array controller. Each SCSI
channel can have up to sixteen SCSI devices (target ID from 0 to 15) attached to it.
W
Write-Through Cache
Refers to a cache writing strategy whereby data is written to the SCSI Drive before a
completion status is returned to the host operating system. This caching strategy is
considered more “secure,” since a power failure will be less likely to cause loss of data.
However, a Write-Through cache results in a slightly lower performance, in most
environments.
