Standard Features
The following features are standard on Compaq ProLiant 2500 models, unless
otherwise noted:
Server Models with Compaq Processor Board
and Intel Pentium Pro Processor
o Standard with one 200-MHz Intel Pentium Pro Processor and integrated
256-KB Level 2 Cache
o Support for two 200-MHz Intel Pentium Pro Processors
o Upgradable to future Intel processors and OverDrive processors
Pentium Pro Processor System Memory
o Error Checking and Correcting Memory uses an encoding scheme for
memory error detection and correction. Specifically, this feature detects
and corrects for single-bit memory errors.
o 32-MB, EDO-buffered, 64-bit system memory expandable to 1 GB
o Supports 60-ns or faster EDO- or FASTPAGE-buffered, 32-, 64-, 128-,
or 256-MB, 4-K refreshed DIMMs.
Expansion Slots
o Six expansion slots: two dedicated PCI slots and four shared
PCI/EISA slots
o The Extended Industry Standard Architecture (EISA) bus provides an
open 32-bit extension to support 32-bit EISA expansion boards,
including full compatibility with Industry Standard Architecture (ISA)
expansion boards.
o The PCI bus provides peripheral transactions at a system clock speed of
up to 33 MHz.

Disk Controller
o Integrated Wide-Ultra SCSI Controller on the PCI local bus. Controller
provides high-performance options for up to five devices without using
an expansion slot. This controller performs at a maximum data transfer
rate of 40 megabytes per second (MB/s).
o Optional controller board available for controller duplexing or
expanding storage capacity beyond five drives.
o For information concerning the SCSI hard drive installation, refer to
the Systems Reference Library CD included in the Reference
Information pack.
Network Controller
o Integrated 10/100 TX UTP controller on the PCI local bus. Features of
the controller include the RJ-45 connector for 10BaseT or 100TX
Ethernet and the AUI connector for 10Base2 Ethernet.
o For information concerning the integrated network controller, refer to
the Systems Reference Library CD included in the Reference
Information pack.
Mass Storage for Hot-Pluggable Models
o Maximum of nine drive bays (four non-hot pluggable in removable
media drive area and five hot-pluggable in drive cage)
o One-third height dedicated removable media drive bay occupied by
1.44 MB diskette drive
o One-third height removable media drive bay occupied by IDE
CD-ROM drive
o Two half-height vacant 5.25” removable media drive bays
o Supports two hot-pluggable drive configurations in the front drive
cage, five 1” hot-pluggable drives or two 1.6” and one 1” hotpluggable
drives

Mass Storage for Non-Hot-Pluggable Models
n Maximum of eight non-hot-pluggable drive bays (four in removable
media drive area and four in drive cage)
o One-third height dedicated removable media drive bay occupied by
1.44 MB diskette drive
o One-third height removable media drive bay occupied by IDE
CD-ROM drive
o Two half-height vacant 5.25” removable media drive bays
o Supports up to four 1.6” non-hot-pluggable drives in the front
drive cage
