EonStor DS3000U


High availability enterprise SAN storage solution

From 2U 12-bay to 4U 60-bay systems, EonStor DS 3000 ensures enterprises have access to storage with future-proof design. Modular hardware means redundancy and easy upgrades, while fast performance allows for speedy operations. For scalability, a range of expansion enclosures can host up to 4PB capacity. Systems can be totally customized when placing orders, with variety of propocols, such as FC, iSCSI, SAS, InfiniBand and FCoE, for flexible hybrid interfaces.

The new DS 3000U with support for SAS 12Gb/s drive side chip is an upgrade from DS3000/3000T's SAS 6Gb/s to remove bottlenecks and offer a faster performance
