Protecting Your Cluster From Power Failure

Dell recommends the following guidelines to protect your cluster configuration from power-related failures:

Use uninterruptible power supplies (UPS) for each cluster node

Implement backup generators and power from separate electrical stations (depending on your situation and environment)

NOTE: See your server and storage system documentation for more information on the specific power requirements for your cluster system's components.

Connecting Standby Power Supplies in the PowerVault System

PowerEdge Cluster FE100/FL100 Datacenter Server configurations require dual standby power supplies (SPS) in the PowerVault storage system. This configuration provides maximum integrity of the storage processor write-cache. The SPS allows the write-caching to complete in the event that the primary power supply fails.

Figure 4-5 shows the location and cabling for the SPS units in the PowerVault system.
