About Your System
The Dell™ PowerVault™ MD3000i is a 3U rack-mounted external Redundant
Array of Independent Disks (RAID) storage array capable of accommodating
up to 15 3.0-Gbps, Serial-Attached SCSI (SAS) disks. The RAID enclosure
can be daisy-chained with up to two additional MD1000 expansion
enclosures, providing access to a maximum of 45 disks in the entire storage
array. Connectivity between the RAID enclosure and the host server is
provided by a standard Ethernet connection, and communication between
the two is established through an iSCSI initiator.
Overview
The RAID enclosure is designed for high availability, offering redundant
access to data storage. It features support for both single RAID controller
configuration and dual RAID controller configuration. For each
configuration, up to 16 hosts can be connected through industry-standard
1-Gb network interface cards (NICs).
The MD3000i storage array provides dual active/active RAID controller
modules, redundant power supplies, and redundant fans. The RAID
enclosure is designed for high-performance environments: eight-node clusters
or multi-host storage access for up to 16 host servers.
Storage management can be either in-band through the iSCSI connection, or
out-of-band using an Ethernet connection to the Management Port on the
RAID controller modules.
