I'm setting up a virtual environment consisting of 10 VM's with 2 primary SQL databases required. The infrastructure allocates two pairs of SQL 2008 R2 Enterprise edition (VM's). The pairs are recommended in order to achieve redundancy, however there are no specific methods recommended in order to achieve it.
The 10 VM's will be running on a single ESXi host, which is connected via SAS 6Gb HBA to a SAN. I am looking for a recommendation in order to achieve redundancy between the two pairs of SQL databases - would Failover Clustering be the way to go?
Are there any recommendations for configuring this failover cluster with vmdk files?
