A couple of months ago, a client asked me
if it’s supported to run Red Hat Clustering Suite within a VMware vSphere
environment.
This kind of question always leads me to
the same answer:
In general, there should be no restrictions
to run any application inside a virtual machine (exception is for applications
that requires an specific hardware to work, like tokens or dongles), others
applications may require a few adjusts to run without any problem, but, the
main point here is to check if the application's vendor supports it on a
virtual environment.
In other words, ask the vendor if their
specific application is supported to run virtualized, otherwise you might end up
without support.
Backing to the Red Hat Clustering Suite,
also knows as RHCS or RHEL Cluster, question:
YES it’s supported.
YES it’s supported.
Since It took me a few hours to check and
confirm this information, I decided to share that with you guys and may be
save you a few hours.
On the Red Hat’s website, you can find VirtualizationSupport for High Availability in Red Hat Enterprise, where the support statement
of clustering solutions on VMware environments could be found.While configuring the solution, there’s one caveat to make it works within a vSphere environment, you have to set up the correct fence agent. Fence support Matrix for Red Hat page describes it in details.
Just one last note, don’t take this as an official statement, those pages could be out of date. Remember my “official “answer: talk with the vendor to get and official statement.
See you around.
