Introduction to Integrity Virtual Machines

Compatibility with HP Virtual Server Environment and HP
OpenView
HP Integrity Virtual Machines is an important component of the HP Virtual Server Environment.
Integrity Virtual Machines is well-integrated with the key elements of the Virtual Server Environment, as
well as with many of HP’s extensive line of OpenView enterprise management products, a few of
which are highlighted here.
Workload management
HP’s Global Workload Manager product automatically controls resource allocation to workloads on
virtual machines in just the same way that it manages them on other partitioning technologies such as
virtual partitions and processor sets. In this way, entire virtual systems may have resource allocation
policies associated with them so that service level agreements may be automatically managed and
monitored.
HP Instant Capacity
Instant Capacity is an option available on many of the HP Integrity servers. This allows you to
purchase a fully populated CPU configuration for your server, but only activate a subset of CPUs
initially. Additional CPUs can be instantly activated to increase capacity or replace failed physical
CPUs on the host. If the Integrity Virtual Machines host has instant capacity processors, they can be
turned on without changes to the virtual machines, which immediately take advantage of the
additional processing power.
HP OpenView Management Software
HP OpenView tools such as GlancePlus can monitor or manage individual virtual machines or the
Integrity Virtual Machines host. Using GlancePlus on the Integrity Virtual Machines host reflects the
physical resource utilization for all virtual machines running on that host. When run in a virtual
machine, GlancePlus monitors resource utilization of the virtual CPUs and I/O for the operating
system running in that VM.
HP Serviceguard
Integrity VM is integrated with Serviceguard, providing two different approachs to high availability of
workloads executing on virtual machines.
First is a revolutionary approach to high availability which provides automatic failover of an entire
virtual machine – including its operating system and application configuration – from one Integrity
system to another in the Serviceguard cluster.
Second is the capability of Integrity virtual machines to participate in Serviceguard clusters just as
other physical servers do. One or more virtual machines may be nodes in a Serviceguard cluster
along with other virtual partitions, hard partitions, or Integrity servers.
