RAID Redundant Array of Independent DisksLevel 0 -- Striped Disk Array without Fault Tolerance: Provides data striping (spreading out blocks of each file across multiple disk drives) but no redundancy. This improves performance but does not deliver fault tolerance. If one drive fails then all data in the array is lost. Level 1 -- Mirroring and Duplexing: Provides disk mirroring. Level 1 provides twice the read transaction rate of single disks and the same write transaction rate as single disks. Level 5 -- Block Interleaved Distributed Parity: Provides data striping at the byte level and also stripe error correction information. This results in excellent performance and good fault tolerance. Level 5 is one of the most popular implementations of RAID. Requires at least three disks.

ServersA server is designed and constructed differently from a PC. The main considerations for server design are the need to handle sustained loads for long periods of time and to monitor and manage the machine.More Expensive Tower or Rack MountDisk (RAID)RedundantPowerMultiple UseMultiple UsersReliabilityBlade ServersVirtualization
