Dell F-Series manual Connecting Multiple PowerEdge Clusters to a PowerVault, San

2.Assign drive letters and volume labels to the disks.

a.Turn off node A.

b.Assign the drive letters on node B by using the Windows NT Disk Adminis- trator or Windows 2000 Disk Management utility to create the drive letters and volume labels. For example, create volumes labeled "Volume E" for disk E and "Volume F" for disk F.

c.Turn off node B. Turn on the node A, and start the Windows NT Disk Administrator or Windows 2000 Disk Management utility.

d.Assign the drive letters on node A.

If the cables are connected properly, the drive order will be the same as on node B, and the drive letter assignments should follow the same order as on the node B. The volume labels can also be used to double-check the drive order by observing that the disk with volume label "Volume E" is assigned to drive letter E and so on for each disk on each node. The drive letter assign- ment should be done on each of the shared disks, even if the disk displays the drive letter correctly.

Connecting Multiple PowerEdge Clusters to a PowerVault

SAN

You can connect multiple PowerEdge clusters to a PowerVault SAN, each with its own PowerVault 65xF storage system. Examples of supported configurations are:

•one direct-attached cluster to one storage system

•the SAN-attached configurations of one cluster to multiple PowerVault 65xF stor- age systems

•one PowerVault 65xF storage system to multiple clusters

However, a configuration with multiple clusters to multiple storage systems is not supported.

More than one PowerEdge Cluster F-Series configuration can share a PowerVault SAN through the use of Fibre Channel switch zoning. By using PowerVault Fibre Channel switches to implement zoning, you can arrange Fibre Channel switch fabric-connected devices into logical groups over the physical switch fabric configuration (a Fibre Chan- nel switch fabric consists of one or more Fibre Channel switches). Zoning automatically and transparently enforces access of information to the zone devices.

You can segment the SANs by setting up zones between different clusters.

NOTICE: If any cluster shares a PowerVault Fibre Channel switch fabric with any other clustered or nonclustered servers and storage systems, you must configure zoning on the Fibre Channel switches.

See the Dell PowerVault 5xF Switches Zoning Guide for information on zoning con- cepts and implementations.
