Linux cluster virtualized for Master - NBU 7

Hi all,

currently we are running NBU 7.1.0.4 under solaris. Because of the benefits of virtual machines (migrations, recoverability, price,..) we are thinkig about moving our master to our ESX 5.1.

After reading all the documentation we found about that, we stated that:

     -there´s no problem on running master in Linux Vmware machines.

     -for ESX 5.1 compatibility we will need RHEL 6.

     -We will need also Netbackup 7.5

In the other hand we would like to create a cluster of two vmware nodes for the master. I understood that it should be done with Veritas Cluster Server.

Is that right? Does anyone got any experience on this?

Thanks in advance.
