3 Host VMware Bundle and SAN
Posted on 2013-11-05
Hi. Our organization is looking into the 3 Host VMware Bundle and SAN for virtualizing our servers. Our sales rep. says if one of the 3 Hosts went down the VMs will be distributed across the remaining two Hosts. The rep. says this is achieved through the SAN. When we asked, what if the SAN failed instead of the 3 Hosts, the rep. gave us an uncomfortable answer. The rep. says there are a number of redundancy built into the SAN. We are not trying to be smart with the rep. but when we asked, what if the one and only single backplane in the SAN dies, the rep. doesn't seem to have an answer except recommending a spare SAN on standby. Can you please share your expertise on generally what is stored on the SAN and what are our risks if the SAN dies (i.e. what if a non redundant component of a SAN failed) ? Thanks!
