Microsoft’s new SKU/licensing chart for the four editions
Two of those editions, Essentials and Foundation, don’t allow you to virtualize anything, so we’re really down to two usable versions of Windows Server 2012: Datacenter and Standard. It’s interesting to note that there are no Enterprise or Web versions anymore, but it’s clear that the world has moved almost entirely to virtualization and that there’s no need to base server editions on their applications.
Instead, both Standard and Datacenter are licensed based on the processors (plus user CALs, but that’s not new), with each license granting you the ability to run Windows on two processors. If you have a machine with four processors, you need two licenses. They also both have the exact same functionality, which is a departure from past models where Datacenter had more high availability features, caching, ADFS, multiple DFS roots, and other entitlements.
In fact, the only difference between the Standard and Datacenter versions of Windows Server 2012 is that with Standard you are only allowed to run two virtual machines in addition to the host OS, whereas with Datacenter you are entitled to run as many as you want. All of this can be found in the Windows Server 2012 Licensing & Pricing FAQ or Microsoft Volume Licensing Reference Guide published by Microsoft.
Second Questions :
Cluster/NLB / Quorum.
why use a cluster I run now hyper-v and the vm is on a CSV. Quick and live migration. <> Yes your vm can be moved but a cluster is more. application redundancy ? <> In my next blog post I will create some real nice cluster config’s
the big question is should I use a quorum or not. Well it depends always on your configuration. but pictures say more than words. and in a next blog post I will get deep on the witness disk/quorum. ( I need a bit time to write the post )
This is a real old picture and maybe there are changes<> I will create a post on this with all the info in it.
