HP Scalable Visualization Array (SVA) Software manual SVA Software Summary, Linux Operating System

See the SVA System Administration Guide for more information on setting up display nodes and devices.

SVA Software Summary

The SVA combines third party software tools and libraries with custom and enhanced software tools and libraries. SVA software must be installed and run on each visualization node as well as the head node of a valid cluster configuration, such as an HP Cluster Platform 3000 or HP Cluster Platform 4000, properly configured for HP XC System Software with the SVA option.

This section describes the following software categories:

•Linux Operating System.

•HP XC clustering software.

•Additional system software.

Figure 3-2illustrates the various software categories and their hierarchical interrelationships, as well as the tasks carried out by the utilities provided by HP Visualization System Software (VSS). These tasks — allocate, launch, initialize, cleanup — are aligned alongside the software categories they impact.

Linux Operating System

The SVA software is layered on top of HP XC System Software Version 3.0, a clustering Linux distribution compatible with Red Hat Enterprise Linux Advanced Server V4.0 Update 2. The kernel version is V2.6.9–x.

See “HP XC Clustering Software” (pg. 24).

The windowing system used by Red Hat is the X.Org windowing system.

Table 3-1summarizes the main operating system components as well as the low-level drivers.
