Expanding The Server As Needs Grow; Configuration Constraints - NEC HV8600 User Manual

Expanding the Server as Needs Grow

A typical minimum system configuration may include the following:
T
Board set consisting of system I/O board, CPU baseboard with one
500 MHz Pentium III Xeon
containing 256 MB of memory
T
Diskette drive and SCSI CD-ROM drive
T
Three SCSI hard drive cages with one hard drive and a RAID controller
installed
T
Integrated LAN controller
T
Four 560 watt power supplies (the fourth power supply provides
redundant power)
T
Onboard 2 MB video memory
T
System I/O board has one ISA slot and seven PCI slots for add-in boards.
The Hot Plug PCI board also plugs into the system I/O board, supporting
up to four Hot Plug PCI board slots. The system I/O board has a riser
board for external I/O (serial, parallel, video, SCSI, USB, LAN,
keyboard, and mouse) interfaces.
T
Chassis can hold six removable media drives: four 5 1/4-inch half-height
bays with a CD-ROM drive installed in one bay; and two 3 1/2-inch half-
height bays with a diskette drive installed.
As server/client needs grow, you can expand system processor capacity,
memory, drives, option boards, and the number of power supplies.
T
CPU backboard has four slots for CPUs, for a configurable range of one,
two, three, or four processors.
T
Two memory boards support 32 DIMM devices, that is16 DIMM devices
per board, for up to a maximum memory size of 8 GB of memory.
T
System I/O board has twelve option board slots (eleven PCI and one ISA
slot).
T
Chassis can hold six removable media drives.
T
Three SCSI hard drive cages support up to 12 hot-swap bays for
3 1/2-inch Ultra2-wide SCSI-2 hard drives.

Configuration Constraints

The system has four 5 1/4-inch half-height bays accessible from the front. These
bays are convenient for diskette, tape, and CD-ROM drives (removable media).
Because of the EMI generated by hard drives, the increased susceptibility to
ESD, and cooling requirements, hard drives should not be installed in the 5 1/4-
inch half-height bays.
