we have 170 ip cameras for connecting the 2 HP servers 85 each and we need to store the recorded files in the SAN storage system for 120 days, the storage is almost 444TB exuding RAID.Our NVR software(Exacq Vision) in running on both servers for recording and video analysis.This is our design.Now we need to fail over server for both HP server , we want 2 physical and two virtual server , one virtual server must be backup server of other and second virtual server is backup server of second physical server.That is back to back setup.Suppose A and B are physical server and A' and B' are virtual server , then A' virtual server inside physical server B and B' virtual server inside physical server A.if any physical server fails then automatically startup the virtual server with zero run time and also access the SAN storage system.Please see the URL and clarify the following
1. Hyper V support this requirement or we need additional software ????
2. Howmany windows server license we need???
3. Our NVR software needs any feature for this???
