The lowdown on IPstorage area networks
What are IP SANs?
IP storage area networks are built on the new iSCSI protocol, which enables the transmission of data across TCP/IP networks using the familiar SCSI protocol.What are IP SANs' advantages over Fibre Channel SANs?
They can transport blocks of data at 1 Gbps. They are cost-effective for most organizations, since most IT staffs are already trained in the use of Ethernet, TCP/IP, SCSI and other common protocols including IP security.Will IP SANs become dominant?
Most observers say no. Even the staunchest proponents of iSCSI say that IP networks are designed to co-exist, not compete, with Fibre Channel SAN technology.When will IP SANs become generally available?
iSCSI host bus adapters are available now, as are a few other SAN components, such as iSCSI switches, routers, servers and concentrators. Look for many more iSCSI products to become available by the end of this year.Must-know info?
Since the iSCSI specifications have only recently been ratified, many vendors are taking a wait-and-see attitude while the market shakes out. Industry analysts are advising users to wait for the next generation of iSCSI products before investing heavily in IP SANs.
