goes beyond the PCI specification in that it is intended as a unifying I/O
architecture for various systems: desktops, workstations, mobile, server,
communications, and embedded devices.
RAID Acronym for Redundant Array of Independent Disks (originally
Redundant Array of Inexpensive Disks) is an array of multiple
independent physical drives that yields performance exceeding that of a
Single Large Expensive Disk (SLED). A RAID disk subsystem improves
I/O performance on a server using only a single drive. The RAID array
appears to the host server as a single storage unit. I/O is expedited
because several disks can be accessed simultaneously.
Serial ATA Serialized AT Attachment. The Serial ATA bus is a high-speed, internal
bus that provides a low pin count, low voltage level bus for device
connections between a host adapter and a Serial ATA device.
Storage Adapter A circuit board that provides a device connection between the host and
the storage devices attached to the storage adapter.
