I plan on deploying two physical servers which will run VMware ESXi and have a number of questions regarding Microsoft licensing. To note, all the VMs on the servers will be configured to run in ESXi's fault tolerance mode. This means that all the VMs on the secondary server will run in lock step with the primary server.
- Would I need to buy Windows Server CAL licenses for each VM on one server? For instance 1 ESXi server has 2 virtual Microsoft servers running on it. Each virtual server has 25 devices (or users) connecting to it. The devices (or users) connecting to each VM would be the same. Would I need 25 or 50 CALs for the physical server?
- Would I need to buy additional Windows 2012 Datacenter Server licenses and the associated CAL licenses for the redundant ESXi server?
Would I need to buy additional SQL 2012 Standard (or Business Intelligence) server licenses and associated CAL licenses for the redundant ESXi server?
And although this doesnt pertain to a virtualized environment, when/how do CALs come in to play with IIS?
Thanks!
