We want to virtualize our servers and convert our desktops to virtual desktops.
We have currently have 8 physical (pentium and Xeon dual cores)servers(: exchange, MS SQL, files server, webserver, domain server.
And desktops that are mixes of pentium and core 2 duo. all run XP. and do mostly outlook, ms office, and some web apps.
I want to first convert all servers to VMWARE and create all new windows 7 based virtual desktops. This because we will not be replacing the workstations soon.
I am thinking of buying 3 DELL R810 Servers with 2x 8-core X6550 processors and 128GB RAM and 2x INTEL Quad Gb ethernet cards each
For storage I am thinking DELL M3220i 4TB Raid-10 SAN with 8x GB ethernet adapters.
My estimate is based on 2 cores per server. (16 cores needed)
5 VDI per core(30 cores needed)
My server have a total of 3x2x8cores= 48 cores
Memory 4Gb per server(32GB)
2G per VDI (300GB)
My servers carry 3*128= 384GB
currently the server use 300GB
I want to give the server 1Tb total and each VDI 20GB
Of course I plan to buy 1 extra server with samr specs in case of failures.
I am not sure if the MD3220i is fast enough. Please give me some insights.
