Sun Cluster Data Service for Sun Grid Engine Guide for Solaris OS

Configuration Requirements

The configuration requirements in this section apply only to Sun Cluster HA for Sun Grid Engine.

Caution – Caution –

If your data service configuration does not conform to these requirements, the data service configuration might not be supported.

Sun Grid Engine Software Version Requirements

Use Sun Grid Engine version 6.0. Make sure to apply the most recent available Patches to the Sun Grid Engine software.

Operating System for the Sun Grid Engine Management Tier

The Sun Grid Engine management tier must run on Sun Cluster nodes. Because Sun Cluster runs only on the Solaris Operating System, the Sun Grid Engine management tier must also run on the Solaris Operating System. However, Sun Grid Engine supports other operating systems. Therefore, this requirement applies only to the management tier, not to individual execution nodes in the grid.

Memory Requirements

Ensure that enough free memory is available on the cluster nodes where you plan to run the Sun Grid Engine master.

The amount of free memory that is required on each cluster node depends on the number of jobs that are running on the grid. For example:

Disk Space Requirements

Ensure that you have enough disk space in the Sun Grid Engine file system and on the local disk of each node.

The disk space requirements for each type of file or directory in the Sun Grid Engine file system are listed in the following table.

File Type or Directory Type 

Required Disk Space 

Binary files 

15 Mbytes for each architecture 

Spool directories 

30–200 Mbytes 

Installation tar file 

40 Mbytes 

On the local disk of each node, 10–20 Mbytes of disk space are required. If you are installing the Sun Grid Engine software on the local disk of a node, 15 Mbytes of disk space are additionally required for the binary files.

Sun Cluster HA for Sun Grid Engine Configuration Requirements

Configure Sun Cluster HA for Sun Grid Engine as a failover data service. You cannot configure Sun Cluster HA for Sun Grid Engine as a scalable data service. For more information, see:

Note –

If you are using the Solaris 10 OS, install and configure this data service to run only in the global zone. At publication of this document, this data service is not supported in non-global zones. For updated information about supported configurations of this data service, contact your Sun service representative.

NFS Configuration for the Sun Grid Engine File System

The Sun Grid Engine file system must reside on a multihost disk. This disk must be available to the other nodes in the cluster that will be used for the Sun Grid Engine administrative services,

You must use NFS to export the Sun Grid Engine file system to the noncluster nodes. The NFS server that exports this file system must also be protected against failure. To protect the NFS server against failure, use the Sun Cluster HA for NFS data service. For more information about this data service, see Sun Cluster Data Service for NFS Guide for Solaris OS.

Sun Cluster HA for NFS Configuration Requirements

Configure the resources for the Sun Grid Engine management tier in the same resource group as the resource for NFS. For more information, see Configuring Sun Cluster HA for NFS for Use With Sun Cluster HA for Sun Grid Engine.

Dependencies Between Sun Grid Engine Components

The dependencies between Sun Grid Engine components are shown in the following table.

Table 3 Dependencies Between Sun Grid Engine Components

Sun Grid Engine Component 

Dependency 

Sun Grid Engine queue master daemon (sge_qmaster)

SUNW.HAStoragePlus resource

Sun Grid Enginescheduling daemon (sge_schedd)

Sun Grid Engine queue master daemon (sge_qmaster) resource

These dependencies are set when you register and configure Sun Cluster HA for Sun Grid Engine. For more information, see Registering and Configuring Sun Cluster HA for Sun Grid Engine.
