Virtualisation hardware help!
Trying to get my head around virtualisation...not easy as there seems to be infinite permutations as to what you can achieve with what hardware/software! Could you guys give me a nod in the right direction...
We're a mid sized secondary with 800 users, and 350 machines.
We have the following hardware:
2 x Dell PowerEdge 2950s running
2 x Dual Core Xeon E5420 @ 2.5Ghz
4 x 400GB 10k SAS drives
These are currently configured as DCs and between them handle DNS, DHCP, File Serving etc...
We have some old legacy HP and RM servers running our SIMS server, AntiVirus and Print services and some desktops running Mahara, Moodle and Censornet.
For storage, we have the 3TB 10k SAS storage locally in the Dells and a further 4TB, connected via fibre, in a Promise E310f (just checked, these are only Hitachi 7K1000 750GB 7200 RPM 32MB Cache SATA 3.0Gb/s 3.5", not sure if they're too slow? Could we swap the SAS drives in the Dells for these and add a couple more?
We'd like to consolidate as many of the servers onto the two Dells probably using VMWare ESXi (going on recommendations from here).
We'd just like to know if the above hardware will achieve what we require and if not, what updates will we need to make etc...I'm guessing we'll need to bump the RAM up at the very least.
Thanks in advance guys, we're obviously completely new to the virtualisation side of things, but I'm sure after a couple of replies, we'll get the hang of it and start moving in the right direction!
