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.
