iSCSI GbE enclosure connects to the host system via iSCSI interface. It can be
configured to any RAID level. The controller provides reliable data protection for
servers and RAID 6. RAID 6 allows two HDD failures without producing any
impact on the existing data. Data can be recovered from the existing data and
parity drives. (Data can be recovered from the rest disks/drives)
Netstor’s iSCSI solution is the most cost-effective disk array controller with
completely integrated high-performance and data-protection capabilities which
meet or exceed the highest industry standards, and the best data solution for
small and medium business (SMB) users.
