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.
