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).
