Introduction Today’s data centers need to be flexible in order to meet the increasing demands from existing customers as well as new project requests. Ideally, these demands are met quickly with minimal overhead while providing a relatively high level of isolation from other workloads. For most data centers, the best solution is one that better utilizes current capacity to satisfy these new demands and provides existing customers with the capacity they expect.

What is HP-UX vPars v6? HP-UX vPars v6 is a software partitioning solution enabling multiple instances of HP-UX to run simultaneously on a single Integrity server or hard partition. Each virtual partition (vPar) is assigned a subset of hardware and runs a separate instance of HP-UX, and hosts its own set of applications. HP-UX instances are isolated from each other at Operating System (OS) and application levels. This total isolation allows for different software patch levels in each vPar.

Why use HP-UX vPars v6? Most data centers have server hardware that is underutilized. These same data centers are facing increasing demand for new applications that results in an increased demand for servers to satisfy their customers. These seemingly contradictory situations have led CIO’s and administrators to the conclusion that they should be able to make better use of the resources they have already deployed.

HP-UX vPars v6 resources CPU and memory In HP-UX vPars v6, the VSP utilizes locality information from the server to automatically assign the best available physical CPU cores and memory to a virtual partition. The CPU cores and memory assigned to a virtual partition are dedicated to that partition, and not sharable. The direct access and locality-aware assignment ensure that maximum performance is maintained for applications running in that vPar.

Integrity Virtual Server Manager While earlier versions of HP-UX vPars provided limited management capabilities in a graphical user interface, HP-UX vPars v6 features the Integrity Virtual Server Manager (VSMGR), a graphical user interface part of the tools of the SMH of the VSP. The VSMGR reports general information about the VSP and allows the creation, the removal and the modification of the resources assigned to virtual partitions.
