This manual describes how to install PS array hardware, configure the Dell's support service is available to answer your questions about PS Series SAN . EqualLogic Storage Installation Guide 1 Rack Mounting the Array Rack See the Group Administration manual for more information. EqualLogic products are iSCSI-based storage area network (SAN) systems marketed by Dell. . Its current primary models are the PS, PS and PS with 1Gb Ethernet and 10 Gb .

Each control module has four network interface ports. These are labeled: eth0, eth1, eth2 and eth3.
A dual control module array has four pairs of ports. The active control module can use network interfaces on the secondary control module if there is a cable connected from the corresponding port on the secondary control module to a network switch. Therefore, you should connect cables to all the network interface ports on each control module to make sure that both control modules can access an interface.
In the example above: Control Module 0 Ethernet 0 and Ethernet 1 ports are connected to Switch 0 and Ethernet 2 and Ethernet 3 are connected to Switch 1. For Control Module 1 reverse these connections so Ethernet 0 and Ethernet 1 are connected to Switch 1, and Ethernet 2 and Ethernet 3 are connected to Switch 0.
Up to two ports on the active control module can failover without contention.
In the above network configuration full availability is maintained by the alternating of the switch connections between the ports of the two control modules. General rules for connecting network cables are as follows: Connect network interfaces in the following order: eth0, eth1, eth2 and eth3. If possible, connect network interfaces to different switches.
To ensure connectivity to the network interface regardless of which control module is active, connect cables to all ports.

Host access to the volume is always through the iSCSI target name, not the volume name. By default, the volume is assigned to the default pool. Do not mount the snapshot, clone, or replica of a clustered disk to a node in the same cluster because it has the same disk signature as the original clustered disk.
Page Volumes Volumes Cloning a volume creates a new volume with a new name and iSCSI target, having the same size, contents, and Thin Provisioning setting as the original volume. The new volume is located in the same pool as the original volume and is available immediately.
Page Replication Replication Replication enables you to copy volume data across groups, physically located in the same building or separated by some distance. Replication protects the data from failures ranging from destruction of a volume to a complete site disaster, with no impact on data availability or performance.
Similar to a snapshot, a replica represents the contents of a volume at a specific point in time. Dell Failover For more information on deploying your cluster with Windows Server operating systems, see the Page Troubleshooting Troubleshooting The following section describes general cluster problems you may encounter and the probable causes and solutions for each problem.
Problem Probable Cause Corrective Action The nodes cannot access the storage The storage system is not cabled Ensure that the cables are connected system, or the cluster software is not properly to the nodes or the cabling properly from the node to the storage
