HP Virtualization Manager and HP Capacity Advisor: an introduction

tions is further divided with Integrity Virtual Machines. Each virtual machine is drawn within
the containing nPartition. The same approach is applied for virtual partitions, Secure Resource
Partitions, and VSE management workloads. This approach makes it simple to determine which
systems are affected by a system configuration change, and the systems that may suffer side ef-
fects from the changes are readily visible. As an example, consider the case where a new cell
must be added to an nPartition. If the nPartition contains Integrity Virtual Machines, the
nPartition cannot be rebooted without coordinating the downtime with the owners of all the
virtual machines. The graphical relationship between the VSE technologies involved in this ex-
ample has not been available in the past, which made management of the various VSE tech-
nologies more difficult. Virtualization Manager’s ability to unify the management of VSE
technologies simplifies this process.
In addition to the partitioning technologies being displayed in the System view, systems
that are members of Serviceguard clusters and gWLM shared resource domains are noted
as such. This enables quick access to the details and management capabilities for clusters and
shared resource domains by simply clicking on the appropriate link. Eventually every tech-
nology in HP’s Virtual Server Environment will be represented in Virtualization Manager
