CHAPTER 5: RAID FUNCTIONS

5.1 O

PERATING SYSTEM

Supports Windows Vista, Windows 7 and Windows 8

5.2 RAID ARRAYS

RAID supports the following types of RAID arrays:

RAID 0: RAID 0 defines a disk striping scheme that improves disk read and write

times for many applications.

RAID 1: RAID 1 defines techniques for mirroring data.

RAID 10: RAID 10 combines the techniques used in RAID 0 and RAID 1.

RAID 5: RAID 5 provides fault tolerance and better utilization of disk capacity.

5.3 HOW RAID WORKS

RAID 0:

The controller “stripes” data across multiple drives in a RAID 0 array system. It

breaks up a large file into smaller blocks and performs disk reads and writes

across multiple drives in parallel. The size of each block is determined by the

stripe size parameter, which you set during the creation of the RAID set based on

the system environment. This technique reduces overall disk access time and

offers high bandwidth.

Features and Benefits

 Drives: Minimum 2, and maximum is up to 6 or 8. Depending on the

platform.

 Uses: Intended for non-critical data requiring high data throughput, or any

environment that does not require fault tolerance.

 Benefits: provides increased data throughput, especially for large files. No

capacity loss penalty for parity.

 Drawbacks: Does not deliver any fault tolerance. If any drive in the array

fails, all data is lost.

 Fault Tolerance: No.

 Total Capacity: (Minimal. HDD Capacity) x (Connected HDDs Amount)
