Here are the environment: Server choices: 1. HP ProLiant ML10 v2: 1x Dual Core 3,1GHz with 12GB RAM 2. HP ProLiant ML110 Gen9: 1x Xeon 1,6GHz with 12GB RAM What you really need to compare first of all are the processors, where more cores is (usually) preferred, then memory speed and lastly, expandability. But of course, it really depends on budget and use case (for example, if IO is critical, I'd spend more on higher performing drives / more drives / caching). There's no clear cut winner here, especially without knowing the price difference and use case. Y. Harddisk: - Raid1 on two SATA 2TB drives Guests: - 1x Windows Server Essentials 2012 R2 - 2x CentOS 7 Clients: - 6 Windows Clients Will the ML10 v2 server serve the needed performance? Because its a way cheaper than the ML110. And will Windows Server 2012 run in oVirt, because on my test machine (HP ProLiant ML350 G5) it didn't (maybe the CPU is to old). regards gregor _______________________________________________ Users mailing list Users(a)ovirt.org <mailto:Users@ovirt.org> http://lists.ovirt.org/mailman/listinfo/users

I just went through trying to get Windows Server 2012 Essentials (both "original" and R2) running on a cluster with Nehalem CPUs, and it would blue-screen during install. I replicated the problem on my Fedora desktop with plain KVM set up to emulate a Nehalem CPU. When I switched to Westmere or newer, Windows worked. This appears to be some difference between Essentials and Standard edition (I am running Windows Server 2012 Standard VMs on my cluster just fine). A co-worker searching around on the Internet also found some VirtualBox users having similar issues with Essentials. So, with Westmere or newer CPU, I think Essentials should be okay, but don't try it with Nehalem.
