PowerVault MD3000 RAID Enclosure
The PowerVault MD3000 RAID enclosure is designed for high availability,
offering redundant access to data storage. It features dual active or active
RAID controller modules, redundant power supplies, and redundant fans.
The PowerVault MD3000 RAID enclosure is designed for high-performance
environments that includes either of the following:
• Two-node fully redundant XenServer hosts
• Multi-host storage access for up to four servers.
XenServer hosts connected to the same RAID controller module can share
the storage volume on the PowerVault MD3000 RAID enclosure. You can
migrate VMs across two hosts using Citrix
®
XenMotion™.
• Built for high-performance, the PowerVault MD3000 RAID enclosure is a
modular disk storage array capable of housing up to fifteen 3.5-inch SAS or
SATA disk drives.
• The PowerVault MD3000 RAID enclosure is expandable by simply adding
up to two additional PowerVault MD1000 expansion enclosures.
• The entire array subsystem is managed from a single, user friendly software
application — known as the Modular Disk Storage Manager (MDSM)—
which streamlines the management and maintenance of storage as it scales.
• In-band management of a PowerVault MD3000 RAID enclosure from a
XenServer host is not supported.
• To manage PowerVault MD3000 RAID enclosures using MDSM, install
the MDSM software on a separate supported Microsoft
®
Windows
®
or
Redhat
®
Enterprise Linux
®
management station.
Citrix XenServer Dell Edition includes the Dell Remote Access Controller
(DRAC) multi-pathing driver that enables high availability configurations
with PowerVault MD3000 RAID enclosures.
