Is there a best way to plan for SQL only ESXi hosts. There are approx 65 sql machines workload is the same. No OLTP involved. Half are in 5.5 and half in 6.5 vSphere. Mix of SQL 2003, 2005, 2008 and 2012. Windows machines are 2003,2008 and 2012. I’m unsure as to current physical core licencing would CPU and memory be the two biggest constraints. At back end SAN is being changed from VNX 5500 to Unity H. Just looking on how best to plan it we are hoping to use two hosts with cpu CPU E5-2690 v4 @ 2.60GHz and they are Lenovo physical servers.
