The
first thing I will dig into is the new features in VMM and share the good stuff
with you.
First
thing first is the ‘availability set’ on the hardware profile for the VMs.
Finally,
we can have a deeper cluster integration with VMM and create and manage this
with this premium management tool.
In other
words, if you have a distributed application – or anything else that should not
be located on the same cluster node, you can create an availability set.
So what does this give?
VMM have
some optimization techniques like Dynamic Optimization and Power Optimization.
Especially
the dynamic optimization option will be a good friend of you once you enable
it, to distribute and re-balance the workloads among a Hyper-V Cluster.
If you
have created an availability set, dynamic optimization will not mess up your
configuration and place the VMs on the same node. Together with the option to
set preferred and possible owners of virtual machines, VMM will always attempt to
keep those virtual machines on separate hosts to secure uptime for your
services.
This is
a well-known cluster setting that we have wanted to see in VMM for a long time.
When you
have created an availability set you might also be glad to know that you can
also prioritize those virtual machines. When a virtual machines is defined as ‘high
priority’, the cluster will then start and place those virtual machines before
medium and low-priority virtual machines. Hyper-V uses values from CPU, Memory
and also NUMA to give the virtual machines best possible performance compared
to virtual machines defined as medium or low.
This is just one part of the goodie pack in SP1 for SC 2012.
More to come.
