iSCSI can be implemented with gateway technology in which an iSCSI controller attaches to a block-level storage array, thus enabling iSCSI transport. Examples of gateway-enabled iSCSI products are available from Reldata Inc. and StoneFly Inc.

In addition, a number of vendors have joined the iSCSI and FC worlds with what's called unified or multiprotocol storage. Vendors such as Microsoft, NetApp and Pillar Data Systems market arrays or software that can attach to the Ethernet network as a NAS or iSCSI device, and to the FC SAN.

Various-sized businesses have adopted iSCSI because it's easy to install, inexpensive, behaves just like Ethernet and doesn't require special skills like FC does.
