4.3 RAID Functions
Operating System
z Supports Windows XP, Windows Vista, and Windows 7.
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.
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 1, 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 capcity 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)
