Performance Analysis of RAIDs in Storage Area Network

Direct Attached Storage, Network Attached Storage and Storage Area Network are the different kind of networking and storage facilities used in different domains from small scale industries to large scale industries. Storage area network is a disk system concentrated on network which allows clients or servers to use the disk system as a local disk. The speed of transmission of data to and from these systems is a crucial element in measuring the availability and reliability of the services provided by the industry. The redundancy of data is very important to provide high data availability; this can be achieved by having RAID (Redundant Array of Inexpensive Disks) methods. This paper describes the performance analysis on RAID levels 0,1,5,6 and10 through IOR benchmark tests on SAN which is implemented using ATA(Advanced Technology Attachment) over Ethernet protocol AoE(ATA over Ethernet). All these tests were performed on eight, 2-TB SAS (Serial Attached Storage) hard drives.
