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)
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.
raid 5
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
