Server features
The design of the server takes advantage of advancements in symmetric
multiprocessing (SMP), data storage, and memory management. The server
combines:
Impressive performance using an innovative approach to SMP
The server supports up to two Pentium III microprocessors. The server comes
with one microprocessor installed; you can install an additional microprocessor to
enhance performance and provide SMP capability.
Large system memory
The memory bus in the server supports up to 4GB of system memory. The
memory controller provides error correcting code (ECC) support for up to four
industry-standard PC133, 3.3 V, 168-pin, 8-byte, registered, synchronous-
dynamic-random access memory (SDRAM) dual inline memory modules
(DIMMs).
