System Overview 1-3
! High reliability and availability
Many hardware components, such as the clock, power, fan, and service
processor, allow redundancy, and the CPU/memory cell board and I/O card
hardware are hot-swap compliant. Easy system recovery is possible even at the
time of failure.
System Features
The Express5800/1000 series servers feature:
! Quad high-performance Intel
®
Itanium
®
2 64-bit 1.3GHz/3MB or 1.5GHz/6MB
processors per Cell Board.
! Cell Board supporting the installation of up to 4 CPUs (Intel Itanium 2
processors).
In addition, each Cell Board has 16 DIMM sockets plus a memory daughterboard
with 16 DIMM sockets for a total of 32 DIMM sockets. Each Cell
Board/daughterboard combination supports from 4 GB (using four 1-GB
DIMMs) up to 32 GB (using thirty-two 1-GB DIMMs) of ECC SDRAM four-
way interleaved memory.
! Intelligent Service Processor (iSP) Board which provides system management
and diagnostic functions
! Clock Board which provides clock distribution
! PCIX Unit in two versions, Base Unit and Core Unit:
14 available PCI-X expansion slots in a Base Unit model; includes eight
64-bit/66-MHz hot-swap PCI-X slots and six 64-bit/133-MHz hot-swap
PCI-X slots.
12 available PCI-X expansion slots, a Basic I/O Board with 2 USB, 2 IDE,
and 1 Keyboard interfaces, a VGA card with an analog interface, and a
DVD-ROM unit in a Core Unit model to allow a bootable partition. The Core
Unit model includes eight (six available) 64-bit/66-MHz hot-swap PCI-X
slots and six available 64-bit/133-MHz hot-swap PCI-X slots.
DVD-ROM unit in a Core Unit
Bay for an optional DAT unit or optional USB FDD
Six hot-swap SCSI hard disk drive bays accessible from the front of the unit;
each drive bay can contain a 36-GB, 73-GB, or 146-GB SCSI hard disk
drive.
! Hot-swap SCSI disk drive backplane; a failed drive can be removed and replaced
with a new drive without system power being turned off (if software mirror has
been configured).
! Hardware monitors (temperature, fans, and voltage) and software monitors to
indicate failures.
