What your xSeries 220 offers

The design of your server takes advantage of advancements in symmetric multiprocessing (SMP), data storage, and memory management. Your server combines:

•Impressive performance using an innovative approach to SMP

Your server supports up to two Pentium III microprocessors. Your 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 your 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 in-line memory modules (DIMMs).

•System-management capabilities

You can use the system-management software that is included with your server to manage the functions of the server locally and remotely. Refer to the documentation that comes with your system-management software for more information.

•Integrated network environment support

Your server comes with an Ethernet controller on the system board. This Ethernet controller has an interface for connecting to 10-Mbps or 100-Mbps networks. The server automatically selects between 10BASE-T and 100BASE-TX environments. The controller provides full-duplex (FDX) capability, which allows simultaneous transmission and reception of data on the Ethernet local area network (LAN).
