Server planning

This information provides server planning requirements that are relative to the fabric.

When you plan for servers in relation to the fabric, consider the following information:

The number of each type of server you require.
The type of operating systems running on each server.
The number and type of host channel adapters (HCAs) that are required in each server.
Which types of HCAs are required in each server.
The IP addresses that are needed for the InfiniBand network. For details, see IP subnet addressing restriction.
The IP addresses that are needed for the service virtual local area network (VLAN) for service processor access from the Cluster Systems Management (CSM) and the Hardware Management Console (HMC).
The IP addresses for the cluster VLAN to allow operating system access from CSM.

Note: You cannot create logical partitions in high-performance computing (HPC) clusters.

Along with server planning documentation, you can use the Server planning work sheet as a planning aid. You can also review server installation documentation to help plan for the installation. When you have identified the frames in which you plan to install your servers, record the information on the Frame and rack planning work sheet.
