Compaq ProLiant CL380 Features 1-17 Power Supplies The ProLiant CL380 comes standard with four power supplies. The system supports: Two 225-watt hot-plug redundant power supplies in the shared storage area. These may be standard AC voltage models or the optional DC voltage models. One 225-watt power supply in each server node. This may be a standard AC voltage model or an optional DC voltage model. NOTE: All power supplies in the ProLiant CL380 must be of the same type. Either all AC voltage or all DC voltage power supplies must be installed in the system. Shared Storage RAID Controller CR3500 One Shared Storage RAID Controller CR3500 provides RAID fault tolerance for the shared storage drives and for the optional shared external storage connected to the shared storage area. Adding an optional Shared Storage RAID Controller CR3500 makes both CR3500 RAID Controllers hot-replaceable and redundant. The additional CR3500 RAID controller also allows for an active/active redundant controller configuration with automatic controller failover and failback. CAUTION: Removing the Shared Storage RAID Controller CR3500 while it is active will make the system inoperable and may cause loss of data.
