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