The 24TB Drobo B800i 8-Bay iSCSI SAN Hard Drive Array is a B&H Kit that bundles Drobo's 8-bay iSCSI enclosure with (8) 3TB hard drives.
The B800i is an 8-bay storage enclosure, designed for use in iSCSI SAN environments. The enclosure supports standard 3.5" SATA hard drives. It is built on Drobo's BeyondRAID technology, which makes it easy to add or upgrade drives as your storage needs increase. You can even mix and match disks of different capacities. The enclosure is compatible with Windows, Mac, VMware vSphere, and XenServer operating environments.
BeyondRAID offers the data protection that is delivered by advanced RAID technology, without the stringent requirements required to create a RAID array. You won't be locked into using the same size disks, and you won't have to migrate data off the array to add capacity. When the array starts to fill up, simply add another disk -- or replace one of the disks in the array with one of a higher capacity. If a disk fails, simply replace it -- no data will be lost.
