The quick hot-swap RAID Cage may or may not be included as a standard part of the server configuration.

Voltage regulator modules

Each processor must have a dedicated voltage regulator module (VRM) which adjusts the voltage supplied to the processor. The VRM for the first processor (CPU 1) is embedded on the system board.

Memory

The system comes standard with 64-MB of ECC RAM. System RAM is expandable up to 2-GB using 100 MHz ECC 72-bit synchronous DRAM (SDRAM) DIMMs (4 DIMM sockets).

Quick Hot-swap RAID cage

The quick hot-swap cage allows you to configure a reliable RAID subsystem. The quick hot-swap cage consists of a drive cage and all of the necessary hardware to install it in the system. Each cage supports three one-inch high 3.5-inch SCA SCSI drives. For optimum operation, use only approved RAID-ready drives in the RAID Cage. The RAID Cage occupies two standard half-height 5.25-inch drive bays.

Drives are mounted on a rail system which provides quick and easy installation and hot-swapping. A fully functional RAID subsystem is controlled by a RAID caching controller.

Hot-swapping is a useful features that allows you to replace a failed hard disk drive without interrupting system operation. In the event of a hot-swappable drive failure, which is part of a RAID 5, the system
