3.7 Running applications on VSP
3.7.1 Recommended applications
VSP is the manageability platform for vPars and Integrity VMs. Though VSP runs the standard HP-UX
OE, it is a controlled environment, and customer applications must not be installed or run on the
VSP. You can run applications on individual vPars and Integrity VM.
The VSP runs vPars and Integrity VM software, which is responsible for allocating processor and
memory resources to the running guests. The VSP can run physical resource, performance, and
software management and monitoring tools.
On the VSP, you can install and run the following software:
• Software installation tool Software Distributor-UX
• Hardware diagnostic and support tools to monitor guests (WBEM, online diagnostics, IRS
(Insight Remote Support)
• HP Integrity Virtual Server Manager a GUI tool to manage VSP and guests
• System performance monitoring tools (GlancePlus, Measureware, OpenView Operations
Agent)
• Utility pricing tools (Instant Capacity, Pay per use)
• Backup software like HP Data Protector (client only)
• Hardware management tools (nPartition Manager, storage and network management tools)
• Multipath storage solutions
• HP Serviceguard (which can be run on HP-UX guests as well)
