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).
