Configuration Considerations

The configuration considerations in the subsections that follow affect the installation and configuration of Sun Cluster HA for Sun Grid Engine.

You can install Sun Grid Engine on one of the following locations:

For the advantages and disadvantages of placing the Sun Grid Engine binary files on a highly available local file system and the cluster file system, see Configuration Guidelines for Sun Cluster Data Services in Sun Cluster Data Services Planning and Administration Guide for Solaris OS.

Tip –

To enable the type of file system to be identified from the mount point, use a prefix that indicates the type of file system as follows:

For mount points on a highly available local file system, use the /local prefix.
For mount points on the cluster file system, use the /global prefix.

The optimum distribution of spool directories and binary files among file systems depends on the grid configuration. See the following table.

Grid Configuration	File System Configuration
The execution tier contains fewer than 200 hosts.	Use a single shared NFS file system under the root of the Sun Grid Engine file system for the spool directories and binary files.
The execution tier contains about 200 hosts, or the applications are disk intensive.	Use a separate area on an NFS file system for the spool directories.
The execution tier contains more than 200 hosts, or NFS performance is likely to be a problem.	See the Sun Grid Engine documentation for alternate grid configurations.
