support SMP. For more information, see the section about using the ServerGuide Setup and Installation CD in the User's Guide on the IBM Documentation CD and the operating-system documentation. If the server has an optional RAID adapter and you have installed or removed a hard disk drive, see the documentation that comes with the RAID adapter for information about reconfiguring the disk arrays. For information about configuring the integrated Gigabit Ethernet controller, see the User's Guide on the IBM Documentation CD. SMP Expansion cabling The cabling information in this section is for multi-node configurations that consist of two, four, or eight servers, for up to 32-way operation. A node is a server that is interconnected with other servers or nodes through the SMP Expansion Ports to share system resources. To configure and cable a multi-node configuration, complete the following steps: 1. Update the BIOS code and the service processor firmware. To download the most current level of BIOS code and service processor firmware, go to http://www.ibm.com/support/. 2. Make sure that each System x3950 E node contains a minimum of one microprocessor and one memory card with one pair of DIMMs. 3. Make sure that each microprocessor in the multi-node configuration is the same cache size and type, and the same clock speed. 4. Make sure that the service processor on each node is configured and connected to the network. See the Remote Supervisor Adapter II SlimLine and Remote Supervisor Adapter II User's Guide for more information. 5. Cable the configuration, using the instructions in this section. 6. Configure the scalable partition. See "Using the Scalable Partition Web Interface" on page 51. 7. Press the power-control button on the primary node to turn on the multi-node configuration manually. Two-node configuration A two-node configuration requires two 2.3-m XpandOnDemand Scalability cable kits. To cable a two-node configuration for up to 8-way operation, complete the following steps: 1. Remove the protective covers from the connectors on the ends of the cables. Protective cover 2. Label each end of the SMP Expansion cables according to where it will be connected to each server.
