Preparing Your Systems for Clustering 53
7
In the
Customize Advanced Virtual Disk Parameters
window, select the
appropriate Virtual Disk I/O Characteristics type from the following
options:
– File system (typical)
– Database
– Multimedia
–Custom
NOTE: If you select Custom, you must select an appropriate segment size.

Select the appropriate Preferred RAID controller module.
For more information on how to create disk groups and virtual disks, see the
Dell PowerVault Modular Disk Storage Manager User’s Guide at
support.dell.com/manuals.
It is recommended that you create at least one virtual disk for each
application. If multiple NTFS volumes are created on a single virtual disk
using Windows Disk Management, the volumes failover together, rather than
individually from node-to-node.
NOTE: It is recommended that you use a RAID level other than RAID 0 (which is
commonly called striping). RAID 0 configurations provide very high performance,
but do not provide the level of availability required for the quorum resource. See the
documentation for your storage system for more information about setting up RAID
levels for the system.
Creating Host-to-Virtual Disk Mappings
Create host-to-virtual disk mappings to assign virtual disks to the host groups
containing cluster nodes as follows:
1
In the
Array Management
window, select the
Mappings
tab.
2
In the
Topology
pane, select:
–Default Group
– Undefined Mappings Node
