Features
Pentium II Processor
The system can include one or two Pentium II
processors mounted on the system board. The board also
contains voltage regulators (Figure 2-3, O and P) to
power each processor. The primary Pentium II processor
plugs into a socket on the this board (Figure 2-3, Q).
This processor features a 512 KB cache. ECC
generation/checking is provided for detection and
correction of cache errors. An optional second Pentium
II processor (Figure 2-3, N) 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.
System Memory
The system board contains four 168-pin DIMM sockets
(Figure 2-3, H). The minimum system board
configuration includes 32 MB of system memory. 4
DIMM sockets allow for system memory expansion to
512 MB. ECC generation/checking is provided for
detection and correction of memory errors.
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 ISA
connectors. The system board offers two dedicated PCI
slots, three dedicated ISA slots, and one shared PCI/ISA
slot.
The system board contains four ISA I/O (input/output)
expansion slots (Figure 2-3, A). The ISA architecture
supports 16-bit memory addressing and 16-bit data
transfers.
The system board also contains three PCI bus I/O
expansion slots (Figure 2-3, C). The PCI architecture
supports 32-bit memory addressing and 32-bit data
transfers. One of these slots shares a common chassis
I/O expansion slot with one of the ISA slots; if you use
this slot as a PCI slot, you cannot use it as an ISA slot.
