RAID (Redundant Array of Inexpensive Drives) is the technology developed to decrease risk involved with the usage of individual disks for Storage. RAID adds realibility & provides performance in Read methods. Well Known RAID Levels are 1. RAID0 - Striping, 2. RAID1-Mirroring, 3. RAID2 - Striping at Bit levelusing Errorcorrection code on disks, 4. RAID3 - BYTE Level striping with parity disk, 5. RAID4 -Block Level striping with Dedicatedparity disk, 6. RAID5 - Striping at Block level with Distributed Parity, 7. RAID6 - Block level striping with Dual Distributed Parity.
All RAID levelsenable Fault Tolerant storage volumes except RAID0.
The star bus topology has the most fault tolerance.
RAID 0 does not provide any fault tolerance.
RAID-5
RAID 0 does not provide fault tolerance, it's to use space form two or more physical disks and increases the disk space available for a single volume. (pg 406)
raid 5
Fault tolerance refers to the ability of a computer network to continue operating properly in the event that one of its components fail. Fault tolerance is therefore important in any network.
Fault Tolerance means that the system will not fail and not stop during the execution (or operation) when a fault is occurred, so fault tolerance mean the ability of handling with faults without stopping the system.
Fault tolerance.
Windows XP supports spanned and striped RAID 0 volumes Hardware RAID is considered a better solution for fault tolerance than software RAID RAID 0 does not provide fault tolerance
to provide fault tolerance
No
RAID 1 OR RAID 5 provide added performance as well as fault tolerance --- GAURAV TOMAR
