We were wanting to transition our companies 5 MS servers to a heftier virtual server. I started studying Vsphere a while back, but wanted advice on which route to take versus EsXI.
I know if we pack everything onto one machine, we'd better have at least one backup. So two monster esxi or vsphere servers? We don't want to hold back on performance when there's so many available options these days. So there will be some expansion backplanes units using a good Raid card.
We've been with Areca for some years now. Never problems with them, only complaint is the CPU layout. When you perform actions on a raid volume, you're generally logged in to the web interface, and they leave no cpu resources for the web interface! So you're lucky if it lets you login. And initializing/reconstructing volumes is painfully slow on Raid6 (40+ hours at least on arc1680i and ar1880. Otherwise a high performer..
The other advantage to the virtual server is utilizing 10gb or 40gb network backbone.
Once this transition is complete, we'll be needing to upgrade our domain controller to something more recent from 2003. Not so much in scope of this question, but just fyi.
I was thinking of building something using a hefty supermicro motherboard with lots of ecc ram. If not Areca, maybe LSI for the raid controller. Stability is priority number one (pretty typical I guess). And I'd really like to know what people are using for SSD Raid layouts this late year. Capacity is really not up there. I'd like to have the OSs on SSD and we may only need a terabyte or two for all servers. Backup volumes, we have seagate enterprise conventional drives and could continue to expand with those. We do use macrium reflect server edition currently (I think it's great).
So, main question is how to mirror the server in the event of a server crash. We'll have cisco managed vlans on 10gbit lines. Depending what route either esxi or vsphere I will go through (or finish) the cbt nuggets or trainsignal series to adopt.
Looking forward to the advice. Thanks in advance.
