Greetings. I am trying setup a HyperV environment to meet similar demands on my VMware Environment. I have VRanger, SRM. We do not use Failover at this time. An unplanned failover looks like the server rebooted and takes 30 seconds or so typically. I will be using Fiber Channel Storage. Onto a plan for HyperV.
I hear the terms "Continuously Available" and "no perceived downtime" for SOFS. It is implied that this is better than a CSV being only highly available. Does it really take a few minutes for a guest to failover with a CSV in an unplanned failover? Does it really take just a few seconds on a SOFS? If so how do we manage no perceived downtime with SOFS in case of a host failure? Do guest VMs on different hosts keep their memory and CPU states in sync? Does SMB introduce latency and extra complexity? Would DPM be the best backup solution? Are there any third part tools to extend failover beyond high, medium, and low? Boot these 10 servers first....etc?
