What your IBM Netfinity 3000 server offers The unique design of your IBM Netfinity 3000 server takes advantage of advancements in data storage, networking, and memory management. Your server offers: Impressive performance using an innovative approach to uniprocessing The Netfinity 3000 server supports one Intel microprocessor installed on the system board (speed and type vary by model). 100 MHz Front Side Bus (FSB) The FSB is the microprocessor external bus. This bus includes the interface to system-board components, and level-2 cache memory for some microprocessors. The FSB is also known as the processor/host bus. Large system memory The memory bus in your server supports up to 384 MB of unbuffered system memory, or up to 768 MB of registered system memory.1 The memory controller provides support for 100 MHz, synchronous dynamic random-access memory (SDRAM) with error checking and correction (ECC). Integrated network environment support Your server supports various network environments. Your Netfinity 3000 server comes with a 10/100 Mbps Ethernet controller on the system board. This Ethernet controller has an interface for connecting 10 Mbps or 100 Mbps transceivers. The server automatically selects between 10BASE-T and 100BASE-TX. The controller provides full-duplex (FDX) operation, which allows simultaneous transmission and reception of data on the Ethernet local area network (LAN). 1 Important: You cannot mix registered and unbuffered DIMMs in your server. To use registered DIMMs, you must remove all unbuffered DIMMs from your server. 4 Netfinity 3000 User's Handbook
