Hello VMware experts,

What are the PROS and CONS of building a Windows fail-over cluster 2012 for SQL DBs in a VMWARE space? Requirements?
is virtual RDM disk the only option? what is required to fully implement? Easy to deploy and maintain? what about the number of SQL licenses required?

If we need also to replicate that DB from primary DB to DR site, should be use SQL Mirroring  or any other technology?

Please advice

The advantages and disadvantages are the same for any VM.

1. RDM disks

or

2. Microsoft iSCSI disk in the VM

You will need the same licenses as per physical machines.

You can use SQL Mirroring, or VM replication.

If I want to use a Windows 2012 failover cluster across VMware hosts, meaning one VM on a physical hosts, and another VM into another physical host, accesing a shared storage,

Is RDM my only option? if so, how many NICs, I need for each physical host to complete the cluster [2 node across hosts]

Any other option rather than RDM disks?

Can you please elaborate in your sentece You will need the same licenses as per physical machines?

Because I will be deploying a WIndows 2012 failover clustering for SQL databases, what license is required for the OS? Standard would be enought or need a higher one

If we decide to implement SQL Always ON, which also requires WSFC, can we implement on WIndows 2012 standard edition as well? what about the SQL licensing?


Please, your feedback is highly appreciated

You must have shared storage to complete a Failover Cluster - RDM presented to ESXi hosts satisfies this Fail,over cluster requirement.

As for network interfaces for the hosts, these should already be in place for your VM Cluster.

Windows 2012 Standard supports Failover Clustering.
