Our company has purchased a new Intel x3500 Server and we intend to run VMWare on it and install 4 virtual hosts to make up the 4 servers for Microsoft Essential Business Server. Our environment is about 100 users. The functions of these four servers will be; (domain controller + file server)(MS SQL)(Exchange)(security+firewall). The physical Intel server will come with 8 x 300GB disks and I am unsure as to what is the best way to setup the RAID of these disks.
I have read that MS SQL and Exchange should preferrably run on their own physical disks. Does this still apply in a virtual environment?
Do I just create one big RAID 5 disk on the server and then allocate the 2.1TB when I create the virtual servers? Or do I create a RAID setup that creates several RAID 1 disks so that each virtual server is running it's own physical disks.
I'm looking for recommendations!
