ISCSI vendor Sanrad has unveiled products for small businesses and departmental users, highlighting the momentum building in that sector (see Sanrad Intros iSCSI V-Switch 2000).
The news reflects two trends emerging in the iSCSI space. First, small is beautiful: IP SANs are being targeted to remote sites that may not need or want costlier Fibre Channel equipment. At the same time, architectural choices are emerging about just where the smarts of an IP SAN should reside.
Let's start at the top. Sanrad's offering a smaller version of its V-Switch, which uses iSCSI to link storage devices and host servers, creating virtual drives that can be accessed and managed via IP.
Sanrad's new box is the V-Switch 2000, a smaller version of its higher-end V-Switch 3000. Like that product, the V-2000 is capable of handling input from 256 servers in 68,000 volumes of storage. But the V-2000 has two ports, where the V-Switch 3000 has four. The price is a bit lower, too: The V-Switch 2000 starts at $12,500 without an accompanying disk array, whereas the V-3000 starts at $15,000.
The part about the optional array is key: Sanrad's claim to fame is that it works with any kind of storage, because its virtualization software is located in an iSCSI switch, not in the storage hardware. If customers want disk storage, Sanrad says its reseller partners can provide ATA RAID arrays along with the switch.
