The 995 server is a compact, high-density, rack mount server with support for one to four Intel® Xeon™ processors MP and up to 24 gigabytes (GB) DDR DRAM memory. The server supports several high-availability features such as hot-plug PCI-X, hot-swap AC/DC redundant power supply modules, hot-swap redundant system fans for cooling, and hot-swap hard drives. The scalable architecture of the 995 server supports symmetrical multiprocessing (SMP) and a variety of operating systems.

The 995 server incorporates features for high availability servers. This includes power and cooling systems with redundancy, hot swap or easy to replace fans hot-plug PCI slots, and a mass storage system with hot-swappable hard drives. These are the key components for increasing availability of the server. Since the fans and power supplies typically have the lowest Mean Time Between Failure (MTBF) specifications, the redundancy of these components permits the server to continue to operate with a failed fan or power supply. With the use of RAID technology the server can continue to operate with hard drive failures The hot-plug hard drives allow a failed hard drive to be replaced while the server continues to operate.

The 995 server baseboard set consists of the 4000832 motherboard, the 6002505 processor board, and the 6002504 memory expansion board. The processor board contains sockets for installing up to four Intel^® Xeon^™ processors MP. The memory expansion board has 12 DIMM slots and supports up to 24 gigabytes (GB) DDR DRAM memory. The motherboard also contains four hot plug PCI-X slots and four non-hot plug slots, I/O ports, and various controllers.

The motherboard is mounted horizontally in a chassis subassembly called the E-bay. The processor board mounts horizontally to the motherboard and the memory board mounts vertically to the processor board. The E-bay is mounted towards the rear of the chassis.

The hard drive bay is mounted at the right side, front of the chassis and supports five 1.0-inch hotswap, Ultra-320 SCSI hard drives. SCSI drives in the hard drive bay can be hot swapped without shutting down the server (provided the operating system supports this function).

The peripheral bay, also located at the front of the system, contains one half-height 5¼-inch device bay (for a device such as a DAT TBU) and a media bay. The media bay accommodates a combo slim-line floppy drive / CD-ROM drive.

The front panel is located above the hard drive bay and provides the user interface for server management.

The power supply bay is mounted at the left side, front of the chassis and supports up to three hot-swap 430-Watt power supply modules in a 2+1 DC output redundant configuration and a 1+1 AC input redundant configuration. A cover plate for an empty power module location is supplied for units without redundancy.
