RAID
Redundant Array of Independent Disks. Represents multiple levels of
storage access developed to improve performance or availability or
both.
RAID level 0
A RAID storageset that stripes data across an array of disk drives. A
single logical disk spans multiple physical disks, enabling parallel data
processing for increased I/O performance. While the performance
characteristics of RAID level 0 is excellent, this RAID level is the only
one that does not provide redundancy. Raid level 0 storagesets are
sometimes referred to as stripesets.
RAID level 0+1
A RAID storageset that stripes data across an array of disks (RAID
level 0) and mirrors the striped data (RAID level 1) to provide high I/O
performance and high availability. This RAID level is alternatively
called a striped mirrorset.
RAID level 1
A RAID storageset of two or more physical disks that maintain a
complete and independent copy of the entire virtual disk's data. This
type of storageset has the advantage of being highly reliable and
extremely tolerant of device failure. Raid level 1 storagesets are
sometimes referred to as mirrorsets.
RAID level 3
A RAID storageset that transfers data parallel across the array disk
drives a byte at a time, causing individual blocks of data to be spread
over several disks serving as one enormous virtual disk. A separate
redundant check disk for the entire array stores parity on a dedicated
disk drive within the storageset. See also RAID level 5.
RAID level 5
A RAID storageset that, unlike RAID level 3, stores the parity
information across all of the disk drives within the storageset. See also
RAID level 3.
RAID level 3/5
A RAID storageset that stripes data and parity across three or more
members in a disk array. A RAIDset combines the best characteristics
of RAID level 3 and RAID level 5. A RAIDset is the best choice for
most applications with small to medium I/O requests, unless the
application is write intensive. A RAIDset is sometimes called parity
RAID.

RAM
Random access memory.
