iSCSI Storage is an excellent method of enabling networked storage at a low price point.

What is iSCSI? (Internet SCSI) is a protocol that encapsulates SCSI (Small Computer System Interface) commands and data in TCP/IP packets for linking storage devices with servers over common IP infrastructures. By using iSCSI, you can supply high performance SANs over standard IP networks like LAN, MAN, WAN or the Internet. The iSCSI standard was defined and ratified by the IETF (Internet Engineering Task Force) in early 2003 to ensure interoperability.

Why should I use iSCSI?

  • iSCSI, a block based storage protocol, is superior in speed (up to 10 times faster) to NFS, CIFS file-based protocols. Therefore, iSCSI can be used with any application including databases.
  • The ease of use of iSCSI and the vast support from different OS’s enable the easy transfer of complete volumes from one host to the other as needed, without investing in additional infrastructure or complicated management schemes.
  • iSCSI delivers everything you can get from Fiber Channel protocol, at 1/2 to 1/5 the price, by deploying highly managed IP SAN infrastructures without building dedicated Fibre Channel infrastructures.
  • iSCSI protocol can deliver block based storage over any kind of IP network. So it can be used for advanced storage applications such as Disaster Recovery.

What is an iSCSI SAN? iSCSI SANs are true SANs (Storage Area Networks) that allow a few to 100's of servers to attach to an infinite number of storage volumes using iSCSI over TCP/IP networks. With IP SANs you can scale the storage capacity to 100's of Tbs with any type and brand of storage system. In addition, you can use any type of network (10,100,1000) and combine operating systems (MS, Linux, HP-UX, Solaris, AIX, Netware) within the SAN network. IP-SANs also include mechanisms for security, data replication, multi-pathing and high availability.
