HP Scalable Visualization Array Version 1.1 System Administration Guide

display blocks that you specify when you create the Display Surface. You create and define Display Surfaces
using the Display Surface Configuration Tool. See "Using the Display Surface Configuration Tool" .
Once you create and define a named Display Surface, it is available for use whenever you launch a
visualization job. Because your cluster can have several display block configurations, you can define one
or more Display Surfaces based on how you choose to use the available display block configurations.
Important
When defining a Display Surface, you must use only display blocks with the same spatial arrangement. For
example, display_b in Table 1-8 has all its display blocks with a configuration of 1W x 1 H. display_f
in Table 1-8 has all its display blocks with a configuration of 2 W x 2H. It does not matter how the spatial
arrangement is generated by the display nodes; that is, by using one or two graphics cards, or one or two
ports.
Table 1-9 lists some (but not all) Display Surfaces that can be built using the display block configurations
listed in Table 1-9:

The Site Configuration File retains all the defined Display Surfaces available for a visualization job. The Site
Configuration File is /opt/sva/etc/sva.conf.
