I think what he is referring to in "single point of failure" is the hardware. So for example if your ESXi host goes down, your Citrix environment is down. Same thing for your Hyper-V host running exchange.

I don’t see any reason why you can’t run additional guests *assuming* that you have sufficient physical resources to service the needs of the guests. I would also ask the business to prioritise the services that they require from IT, and the maximum acceptable downtime is (until either a workaround or restoration of service). Putting things onto a single host creates a single-point-of-failure (SPOF), and the business needs to understand the implications of losing all those services at once (i.e. in a worst case scenario, how long will it take to get everything running again or other mitigation in place) Cheers Ken From: listsad...@lists.myitforum.com [ mailto:listsad...@lists.myitforum.com] On Behalf Of J- P Sent: Thursday, 20 June 2013 12:54 PM To: ntsysadm@lists.myitforum.com Subject: RE: [NTSysADM] NAS or Server on a seperate note, what is your personal opinion on hyper-V host running guest running Exchange, should the V-host not run any other guest other than Exchange?

If that's what you're planning for, then you need to have some idea of what that is. Frankly, for that size environment, anything over 18-24 months is pure speculation, and you'll spend more wisely by planning for only 2 years rather than 5. Things change.

As an aside you might want to look at upgrading to at least 2008 R2 or better 2012, have at least 2 DC's, and get all the file/print off the DC when you go this route.

Fast Forward 2013 - single site , single domain 1. ESXi hosting a VM 2008 Citrix TS, and a VM 2003 DC (no storage really available) 1. Windows 2012 Hyper-V host, SAS mirror for host OS, raid 10 2TB for guest OS', currently one guest, 2012 with Exchange 2013. Now there are 60 users, (still using original 2003 for File Print and DNS) and storage demands, as we all know are increasing exponentially, so I get the "we need more storage " so this begs the question, new server 2u (R710 maybe) , or a NAS 8 or 12 bays maybe- As an aside, majority of the users use basic office files, but there are about a dozen that deal with CAD Audio and Video I want this solution to be good for 3-5 years ----------------------------------------- This message, and any attachments to it, may contain information that is privileged, confidential, and exempt from disclosure under applicable law.
