Hyper-V in Windows Server 2012 is everything feasible in terms of technical, economical (financial) and operational. As such, it is entirely the wisest decision of all to deploy Hyper-V in Windows Server 2012 from whatever hypervisors platform that one is currently using. Several undisputed justifications are as follows: -
Economical (Financial) Feasibility of Hyper-V 2012
A strong huge majority of Virtualization users are highly impressed by the SMB3 cluster of Hyper-V in Windows Server 2012. Customers now have an option to avoid investing on expensive hardware SAN storage or they can opt for the SMB3 file share that makes SMB3 cluster deployment in Windows Server 2012 without expensive SAN investment.
However, for uses that already have existing SAN investment, they can go for the new Virtual Fiber Channel in the new Hyper-V Manager in Windows Server 2012 so as to fully leverage their existing SAN investment, therefore this posts no bad news to these users as well.
Another next big thing of Hyper-V in Windows Server 2012 is its support for Shared Nothing Live Migration, where no shared infrastructure is required between 2 hosts to live migrate a VM or a VHDX. This saves considerably large amount of investments in terms of dollars and cents.
Technical Feasibility of Hyper-V 2012
For Hyper-V replica, customers that do not previously deploy Hyper-V due to this can unhesitantly do it now in Hyper-V of Windows Server 2012.
In terms of offloading the host processor’s load, IPsec offloading comes in just handy enough for this. For improved performance of VM, VMQ & SR-IOV appears to be impressive too. A good blog on SR-IOV is here http://blogs.technet.com/b/matthts/archive/2012/10/13/windows-server-2012-hyper-v-and-sr iov.aspx
In another context of technical feasibility, Dynamic memory / RAM & Dynamic bandwidth management (either via UI or Powershell) are now truly and readily available in Windows Server 2012’s Hyper-V.
Operational Feasibility of Hyper-V 2012
The UI of Hyper-V 2012 looks very much the same as in Hyper-V R2. Of course with a couple of impressive improvements that are given thumbs-up by many Virtualization experts. Simplicity of management is the key here; One doesn’t matter-of-factly need much training to learn/start using Hyper-V in Windows Server 2012 intuitively, as its interface is extremely user-friendly. This awesome piece of product is engineered based on extreme ease of use and simplified management in mind, fitting it perfectly well in datacenters, clouds, hosting company environments where multi-tenancy is a concern.
In the nutshell, based on dynamically changing business requirement in today’s cloud centric industry scenarios, be it datacenters, clouds, hosting providers and many more, it is wise to opt for Windows Server 2012’s Hyper-V 2012 as the pick of your choice.
This is because Hyper-V in Windows Server 2012 prevails in terms of technical feasibility, operational feasibility as well as economical (financial) feasibility, which are the main key factors in all businesses ranging from SMBs to MNCs. When these 3 feasibility studies are affirmative, there is a green light for this project (Transitioning to Windows Server 2012 Hyper-V).
