Internet Engineering Task Force (IETF) has finally approved
iSCSI as a standard. With iSCSI enterprises can build
SANs using their existing Ethernet networks since both
are IP-based technologies. Until now organizations that
needed SANs had to opt for separate Fiber Channel networks,
and that meant additional costs.
A number of iSCSI products appeared in the market while
the industry was waiting for iSCSI to be ratified. These
were based on draft specifications. We can expect many
new iSCSI products from startups and established companies
in the months ahead.
of these products are storage arrays, adapters, TCP
acceleration chips, and software for IP storage. Vendors
are also expected to provide drivers and make their
products compatible with iSCSI.
Vendors like Cisco, IBM, EMC and Netapp have been strong
backers of this standard. In 2000, Cisco and IBM first
submitted the basic framework for this block level IP
storage protocol to IETF.
Analysts say that large enterprises moving away from
direct attached storage are expected to stick with Fiber
Channel. However, SMEs will opt for more affordable
