Vmware ESX 5 from a Vcenter
Two Windows 2008 R2 VMs
I am attempting to setup Failover Clustering using two VMs from within a Vcenter. Each virtual machine resides on a seperate physical host following this schema:
The instructions for adding a disk to the first machine go as follows:
- In the vSphere Client inventory, select the newly created virtual machine and select Edit Settings. The Virtual Machine Properties dialog box appears.
- Click Add, select Hard Disk, and click Next.
- Select Raw Device Mappings and click Next.
- Select an unformatted LUN and click Next.
- Select a datastore and click Next.
This datastore must be on a SAN because you need a single shared RDM file for each shared LUN on the SAN.
My question is as follows. When two Windows 2008R2 servers are hosted on two different physical VMWare servers within a VCenter, is it absolutely necessary to have an unformatted LUN for the shared storage of a Windows Failover Cluster?
If not, what would be an alternative?
iSCSI is not an option. Both servers must be installed on two seperate physical hosts.
Here is a link to the documentation.
