RAID Controllers and RAID Controller cards
Definition: A RAID controller is a hardware device responsible for
managing physical drives in a system and presenting them to the computer as
The setting up of
RAID 0 and
RAID 1 can be done either via software or hardware.
Some operating systems allow you to setup RAID in the software itself. A better option
is to have a dedicated piece of hardware controlling the RAID functions. A guide to
software RAID in Linux.
RAID controller chips are often imbedded in the motherboard. They also come in the
form of a PCI expansion cards.
You need to ensure that the RAID controller card is designed for the type of hard
disks you are using. A RAID controller card designed for use with IDE hard disks will
not take SCSI hard disks. A controller designed to provide just RAID 0 functions will
not allow you to set up a
fault tolerant array.
The big names in the RAID controller business are
Adaptec, Highpoint, Intel and
Highpoint and Promise supply most of the RAID chips that are imbedded in both single CPU
and dual processor motherboards. They also make the RAID controller cards which are sold
on their own. Intel uses it's RAID controller chips in motherboards they produce, Adaptec
is mainly known for it's SCSI based products including SCSI cards and SCSI RAID controller
cards. Many of the manufacturers also build specialist RAID controller cards for use in
"non-standard" situations, eg low profile RAID controller cards for use in restricted spaces
like 2 U server cases etc. You can even get RAID for use with newer technologies like SATA.
Companies like 3Ware manufacture SATA RAID controller cards.
