IBM PowerVM is virtualization solution for AIX environments on IBM POWER technology. In IBM PowerVM environment, multiple logical partitions (LPARs) can be carved in a physical server, also called the managed system. The LPARs can be assigned physical or virtual resources. The Virtual I/O Server is a dedicated partition and is a software appliance with which you can associate physical resources and that allows you to share these resources among multiple client logical partitions. The Virtual I/O Server can use both virtualized storage and network adapters. The managed system, LPARs and the resources are managed using the Hardware Management Console (HMC) appliance sitting outside the physical frame.
You can use Veritas Cluster Server (VCS) by Symantec in a IBM PowerVM virtualization environment to provide mission-critical clustering and failover capabilities.
The following configurations are supported:
LPAR to LPAR Clustering and Fail-over for LPAR availability (virtual machine) availability
VCS runs in one LPAR on each physical server, known as the management LPAR. The management LPAR behaves as a control point, and provides high-availability to the other LPARs running on the same physical server. The management LPAR views the LPARs that it manages as virtual machines but does not have visibility into the applications on the managed LPARs.
You can create a cluster of the management LPARs on more than one physical server to provide failover between the managed LPARs on the different physical servers.
VCS can also run inside the individual managed LPARs to provide high-availability for applications running inside the LPAR.
