Configuring Storage 35

Creating an SR on PowerVault MD1000 or PowerVault MD1120 Storage

Enclosures

The process to create an SR on virtual disks on the

PowerVault MD1000 or

PowerVault MD1120

controller is the same as creating an SR on the local hard

disk storage of the host. For more instructions on creating an SR on the

PowerVault MD1000 or PowerVault MD1120 storage enclosures

, see "Local

Storage Repository (SR) Configuration" on page 29.

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 inlcudes either of the following:

• Two-node fully redundant XenServer hosts

• Multi-host storage access for up to four servers.

XenServer hosts connected to same RAID controller module can share

storage volume on the PowerVault MD3000 RAID enclosure. You can migrate

VMs across two hosts using 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 Micorsoft

Windows

Redhat

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.
