Power loss to ESXi, SAN & Physical dc
Over the summer we had an expensive VMware, ESXi 5.1 system installed. 2 ESXi servers running on a 1TB SAN. All this Dell hardware sits on a Dell UPS 2700 W. I've just discovered that the UPS isn't configured to do anything when mains power is lost and the Network Management Card hasn't been installed (just found it in a box)
When I asked the people who installed the system about the unconfigured UPS I was told the installation and configuration of the network management card was "massive massive overkill". This doesn't seem right to me as there are 15 virtual servers (1 physical) including a SIMs server, that ideally should be shutdown gracefully. On top of that I've been reading that there is a procedure for shutting down the SAN to prevent data loss.
Thoughts would be most welcome, is this overkill?
Many thanks and have a great crimbo
