Yes. If you only want to share iSCSI, then iSANmp is what you need.
iSANmp is identical to SANmp — easy to use SAN sharing software, same great features, no extra servers, no metadata networks, compatible with Final Cut Pro, Avid, Adobe, Pro Tools, Mac and PC, most arrays, etc. — but it’s iSCSI-only (instead of Fibre Channel and iSCSI) and at half the price it’s the perfect solution for budget minded, small to medium sized businesses and do-it-yourselfers.
You can download and try SANmp/iSANmp and install it on an unlimited number of workstations.
