garethEds Posted March 27, 2012 Posted March 27, 2012 Our journey through virtualisation is still ongoing and in the research phase (as it has been for over a year). Funding maybe available soon and after looking and deciding on Citrix we have now decided to re-look at HyperV. As I look at the trial download on Microsoft, can anyone tell me the difference between: HyperV Server 2008R2 and the version that comes built into Windows 2008R2? Am I right in thinking one is a barebones and would boot off usb stick? Do they come with all features or are there any paid for versions of HyperV? We are licensed as part of our EES for 10 servers - would this include HyperV? What would you guys use? The WIndows 2008R2 version or the barebones version? Gareth
ChrisH Posted March 27, 2012 Posted March 27, 2012 It is just the barebones like you say so it's just server core with hyper v in a custom package. 1
garethEds Posted March 27, 2012 Author Posted March 27, 2012 It is just the barebones like you say so it's just server core with hyper v in a custom package. Thanks Chris. And you can confirm there is no difference at all? Nada? Zip? WHich one do you think I should use? GJE
ChrisH Posted March 27, 2012 Posted March 27, 2012 The dedicated hyper v is dedicated to that use so you won't be able to add components to it like you would if you use server core and install the hyper v role.
Arthur Posted March 27, 2012 Posted March 27, 2012 Am I right in thinking one is a barebones and would boot off USB stick? Hyper-V Server can be booted from a flash drive, but OEMs are the only ones officially allowed to do this. Windows Server 2008 R2 on the other-hand can only be booted from a fixed HDD/SSD. What would you guys use? The Windows Server 2008 R2 version or the barebones version? I can't see any particular reason to go with the standalone version of Hyper-V. I think it's main purpose is for VDI... The free product, Hyper-V Server 2008 R2, has a role. This edition, which has only a Server Core installation option (command line only), offers no free licenses. It might be an option for those who are converting already licensed physical servers where purchases of the Standard, Enterprise, or Datacenter editions make no economic sense. It has a similar specification in features and capacities as the Enterprise edition. It will also play a role in Virtual Desktop Infrastructure (VDI) deployments where the free Server licensing of the paid-for editions offers no benefit. (Source, p164) 1
rich_tech Posted March 28, 2012 Posted March 28, 2012 I think the major thing we wanted to know most of all, is if there is any problems with performance if you just build your server as 2008R2 normal and just add a role then for the hyper-v, this is all we intend running on the two high spec servers we are going for ? or do we need to just put core on to get max out of it all, our immediate plans here are to virtualise and replace some of our very old legacy servers onto our platform when we get it all set up, possible things like app virtualisation can be looked at later.
sted Posted March 28, 2012 Posted March 28, 2012 not noticed any huge performance drops running 08r2 standard/enterprise with vms on top (with the proviso you leave the host os at least 2gb ish of ram start shrinking that too much and the host slows to a crawl) 2
rich_tech Posted March 28, 2012 Posted March 28, 2012 thanks for confirming that, its what I was thinking would be the case there
garethEds Posted March 28, 2012 Author Posted March 28, 2012 not noticed any huge performance drops running 08r2 standard/enterprise with vms on top (with the proviso you leave the host os at least 2gb ish of ram start shrinking that too much and the host slows to a crawl) Our host PCs will have between 48 and 96Gb - I hope that's enough. GJE
SYNACK Posted March 28, 2012 Posted March 28, 2012 Our host PCs will have between 48 and 96Gb - I hope that's enough. GJE As long as your VMs leave @-3GB for the host that should be fine, just don't try to allocate it all to VMs
garethEds Posted March 28, 2012 Author Posted March 28, 2012 As long as your VMs leave @-3GB for the host that should be fine, just don't try to allocate it all to VMs As I have not looked at HyperV yet (book arrives tomorrow) can I assume this can be set somewhere? Gareth
sparkeh Posted March 28, 2012 Posted March 28, 2012 As I have not looked at HyperV yet (book arrives tomorrow) can I assume this can be set somewhere? Gareth Yes and if memory serves it warns you if you don't leave enough for the host.
Achandler Posted March 28, 2012 Posted March 28, 2012 It won't let you give the last 1 gig away, but leaving Server 2008R2 with only 1 gig is no an idea that should be entertained.
