We currently have a SAN with a combination of SATA drives and fast fibre channel disks. We have 4 host 2950 servers as hosts for virtual servers using vmware.
Our SQL servers are having performance issues and i wondered how people would configure their SQL servers. We have a combination of heavy read and heavy write databases.
I have read you should not virtualize your SQL servers and other documents that you should.
What configuration should I use and should they be virtual or physical (my boss has decided that RAID 10 is not needed and RAID 5 is adequate because we are only a college)
