Storage August 2006 Special Supplement

iSCSI is less complex and cheaper than Fibre Channel, making it a good choice for small- to medium-sized businesses replacing DAS.


Deployments of IP SANs by small- and medium-sized businesses (SMBs) are growing rapidly and many large data centers are starting to use iSCSI-based storage to support non-mission-critical applications. Stamford, CT-based Gartner Inc. forecasts that the number of servers connected to an iSCSI SAN will exceed Fibre Channel (FC)-attached servers by 2009.

SMBs are embracing iSCSI because of the following:

  • iSCSI SANs are less expensive than FC SANs.
  • An iSCSI SAN is based on the familiar and ubiquitous TCP/IP protocol.
  • iSCSI SANs are less complex and easier to manage than FC SANs.
