I current have several servers and would like to bring this down to 2 or 3 servers to save power costs and of course management.
I have spec'd out some Dell 720's with dual processors, 16GB Ram and SAS 15K hard disks in RAID 1 using PERC controllers.
Question is which virtualization software should i use for this pupose? I am planning to put no more then two virtual servers on each box but on some would like to use one virtual server and keep the other free just in case i need to move a container from one to the other for either load balancing or redundancy.
Not knowing much about virtualization i am a little unsure on how it works. I would like to keep some capacity on each box for redundancy or another OS.
Also, it would be nice if the Virtualization software is either free or low cost.
