About Your System
The Dell™ PowerVault™ MD3000 is a 3U rack-mounted external Redundant Array of Independent
Disks (RAID) enclosure capable of accommodating up to 15 3.0-Gbps, Serial-Attached SCSI (SAS)
disks. Connectivity between the RAID enclosure and the host server is provided by Dell SAS 5/E
Host Bus Adapters (HBAs).
Overview
The RAID enclosure is designed for high availability, offering redundant access to data storage. It
features dual active/active RAID controller modules, redundant power supplies, and redundant fans.
The RAID enclosure is designed for high-performance environments: two-node clusters or multi-
host storage access for up to four servers.
Storage management can be either in-band through the SAS connection, or out-of-band using an
Ethernet connection.
NOTE:
Dell recommends that you configure your MD3000 to use both in-band and out-of-band management
paths. Establishing all management connections to a RAID enclosure provides additional paths in the case of
a management connection failure.
