22 Setting Up the Dell|EqualLogic PS Series SAN

When creating a group and configuring arrays as group members, ensure the

you have:

• Choose the group RAID level that is optimal for your application

performance. Before creating a PS Series group, you should determine

which RAID level. To configure on the group members (storage arrays) you

can choose from RAID 5, RAID10 and RAID 50.

NOTE: Both the RAID levels provide adequate performance and fault

tolerance for data volumes.

For more information on RAID levels in a PS Series group, see the

technical report

Understanding Group RAID Levels

on the EqualLogic

Customer Support website

at www.equallogic.com

• You must configure at least two network interfaces on each group member

in order to configure multipath I/O. For example, connect one network

cable to the

eth0

interface and another network cable to the

eth1

interface. Then, connect the cables to different switches. Then, use the

Group Manager GUI or CLI to configure each interface.

After the group is configured, you can create volumes and then access the

volumes from the cluster nodes.

Configuring Volumes in a PS Series Storage Array

You can use the Group Manager GUI or CLI to create volumes. To use the

GUI, connect to the group IP address from a web browser and log in to an

administration account, such as grpadmin. The Group <groupname>

windows appears, where groupname is the name of group you are configuring.

Click and expand items in the far left panel of the GUI for detailed

information about group components. Tasks such as creating volumes are

shown in the Activities panel.
