Using multiple SAN solutions

I thought this was intresting Forum Discussion at the VMware Communities, Using multiple SAN solutions

Hi everyone,

I am reviewing our vmware environment and I have a question regarding multiple SAN implementations.
Currently we have diverse clusters and I am looking at combing these where possible.
In our environment we have two different SAN solution and this could be more in future.
We will be looking into storage virtualization but that is another story.
In the mean time I would like to know if it is ok to connect a host to more than one storage array?
Actually all hosts in cluster would probably have this configuration for obvious reasons.
Reasons for wanting to do this is obviously because we have them and also so I can mix workloads on the servers.
My fast or critical vmdks could be stored on the enterprise SAN while the entry level SAN can be used for less
critical VMs.

Check out the comments, if you don’t know the answer.
