7.2 Hardware Requirements for a Hard Partition in a Cluster

The TruCluster Server hardware requirements are the same for an AlphaServer GS80/160/320 hard partition as any other system in a cluster. You must have:

•A supported host bus adapter connected to shared storage. This may be a KZPBA-CB for parallel SCSI, or a KGPSA-CA for Fibre Channel.

•One or more network connections.

•A Memory Channel interface. The AlphaServer GS80/160/320 system supports only the MC2 products.

Each AlphaServer GS80/160/320 hard partition that is used in a cluster must contain at least one QBB with a minimum of one CPU and one memory module. Additionally, there must be:

•At least one local I/O riser module in the partition. Figure 7–1 shows a portion of an AlphaServer GS160 QBB with an I/O riser module with a BN39B cable connected to port 0.

•At least one I/O riser in the partition must be connected to a primary PCI drawer that provides the console terminal and operating system boot disk. For example, the portion of the cable on port 0 of the local I/O riser shown in Figure 7–1 could be connected to the I/O Riser 0 (0-R) connector in Figure 2–1 and Figure 7–3.

A primary PCI drawer contains a standard I/O module that provides both standard reference module (SRM) and system control manager (SCM) firmware. You can connect additional I/O risers in the partition to expansion PCI drawers.
