Section 3 - Configuration
What is RAID?
RAID, short for Redundant Array of Independent Disks, is a combination of two or more disks with the aim of providing fault tolerance and improving performance. There are several different levels of RAID, with each providing a different method of sharing or distributing data amongst the drives. The
RAID 0 RAID 0 provides data striping, which spreads | RAID 0 |
out blocks of data over both drives, but does not |
|
provide data redundancy. |
|
Although performance is improved, the lack of |
|
fault tolerance means that if one drive fails, all |
|
data in the array will be lost. |
|
RAID 1 RAID 1 provides mirroring over both disks, with | RAID 1 |
the same read/write speed of a single disk. A |
|
RAID 1 array can only be as large as it’s smallest |
|
member disk. |
|
Because the data is stored on both disks, |
|
RAID 1 provides fault tolerance and protection, |
|
in addition to performance advantages. |
