Features
Processor
The system can include one or two Pentium Pro
processors mounted on the processor/memory board.
The board contains DC to DC converters for power to
each processor (Figure 2-4, D) . The primary Pentium
Pro processor plugs into a Zero Insertion Force (ZIF)
socket on the this board (Figure 2-4, B). This processor
features either a 256 KB or 512 KB cache. An optional
second Pentium processor (Figure 2-4, C) enhances
performance and enables
symmetric multiprocessing
(SMP). Both processors access the same memory and
I/O space and tasks can run on either CPU if your
operating system (OS) supports SMP.
Memory
The processor/memory board contains eight 168-pin
DIMM sockets (Figure 2-4, A). The minimum system
board configuration includes 32 MB of system memory.
8 DIMM sockets allow for system memory expansion to
1 GB (using 128 MB DIMMs.) ECC generation/checking
is provided for detection and correction of memory
errors.
Note: Only use DIMMs approved for use in this server
system. Call your customer service representative for
information.
Bus Master I/O Expansion Slots
The server's expansion capabilities meet the needs of
file and application servers for high performance I/O by
providing a combination of PCI local bus and EISA
connectors. The system board offers four dedicated PCI
slots, three dedicated EISA slots, and one shared
PCI/EISA slot.
The system board contains four EISA bus master I/O
(input/output) expansion slots (Figure 2-3, A). The
EISA architecture supports 32-bit memory addressing
and 16-bit or 32-bit data transfers for the CPU, DMA,
and bus masters.
