HP Insight Control - Manual (Page 9)

2 Key concepts
Heterogeneous environment
A heterogeneous environment hosts virtualization layers, such as VMware ESX, Hyper-V, and so
on. Insight Control virtual machine management supports the heterogeneity by providing a uniform
way to access and manage all the hypervisors. For information about the supported hypervisors,
see the HP Insight Management Support Matrix available at:
www.hp.com/go/insightcontrol/
docs .
Virtual machine
A virtual machine is a software running on a physical machine, which shares all the resources of
the host machine, and has its own operating system.
Virtual machine host
A host machine is a system with a hypervisor installed on it to host virtual machines. A host machine
can have more than one virtual machine hosted on it.
Virtual machine guest
A virtual machine guest is a virtual machine running on a virtual machine host.
Handling Pre-Failure Alerts (PFA)
Systems Insight Manager can detect certain pre-failure alerts and generate corresponding events.
Insight Control virtual machine management uses VMotion for VMware ESX and Live Move capability
for Microsoft Hyper-V R2 servers as event handlers for these events, so that the virtual machine can
be moved to an alternate host before the system fails or is placed in maintenance mode.
The handling pre-failure events feature is supported in the following virtual machines on shared
storage:
•
VMware ESX, where the ESX Host is enabled for VMotion.
•
Microsoft Hyper-V R2 servers, where the virtual machines are HA-enabled and powered on.
