Since the emergence of vSphere 6.0, I would like to write an article on vSphere 6.0 vs Windows Server 2012 R2. I collected vSphere 6.0 features from few blogs and VMware community forum. Note that vSphere 6.0 is in beta program which means VMware can amend anything before final release. New functionalities of vSphere 6.0 beta are already available in Windows Server 2012 R2. So let’s have a quick look on both virtualization products.

Certificate Authority | Active Directory Certificate Services |
| Certificate Store | Certificate Store in Windows OS | |
| Single Sign on | VMware retained SSO 2.0 for vSphere 5.5 | Active Directory Domain Services |
| Database | vPostgres database for VC Appliance up to 8 vCenter | Microsoft SQL Server

| vMotion | Long distance Migration up to 100+ms RTTs | Multisite Hyper-v Cluster and Live Migration |
| Storage Migration | Storage vMotion with shared and unshared storage | Hyper-v Live Storage Migration between local and shared storage |
| Combined Cloud Products | Platform Services Controller (PSC) includes vCenter, vCOPs, vCloud Director, vCoud Automation | Microsoft System Center combined App Controller, Configuration Manager, Data Protection Manager, Operations Manager, Orchestrator, Service Manager, Virtual Machine Manager |
| Service Registration | View the services that are running in the system. | Windows Services |
| Licensing | Platform Services Controller (PSC) includes Licensing | Volume Activation Role in Windows Server 2012 R2 |
| Virtual Datacenters | A Virtual Datacenter aggregates CPU, Memory, Storage and Network resources. | Provision CPU, Memory, Storage and network using create Cloud wizard |
Another key feature to be compared here that those who are planning to procure FC Tape library and maintain a virtual backup server note that vSphere doesn’t support FC Tape even with NPIV and Hyper-v support FC Tape using NPIV.

Microsoft’s Hyper-v Server 2012 and System Center 2012 Unleash KO Punch to VMware
In most of the SMB customer, the nodes of the cluster that reside at their primary data center provide access to the clustered service or application, with failover occurring only between clustered nodes. However for an enterprise customer, failure of a business critical application is not an option. In this case, disaster recovery and high availability are bonded together so that when both/all nodes at the primary site are lost, the nodes at the secondary site begin providing service automatically, or with minimal intervention.
The maximum availability of any services or application depends on how you design your platform that hosts these services. It is important to follow best practices in Compute, Network and Storage infrastructure to maximize uptime and maintain SLA.
The following diagram shows a multi-site failover cluster that uses four nodes and supports a clustered service or application.
The following rack diagram shows the identical compute, storage and networking infrastructure in both site.
Physical Infrastructure
Storage Requirements
Since I am talking about highly available and redundant systems design, this sort of design must consist of replicated or clustered storage presented to multi-site Hyper-v cluster nodes. Replication of data between sites is very important in a multi-site cluster, and is accomplished in different ways by different hardware vendors. You will achieve high performance through hardware or block level replication instead of software. You should contact your storage vendor to come up with solutions that provide replicated or clustered storage.
Examples are:
Network Requirements:
A multi-site cluster running Windows Server 2008 can contain nodes that are in different subnet however as a best practice, you must configure Hyper-v cluster in same subnet. You applications and services can reside in separate subnets. To avoid any conflict, you should use dark fibre connection or MPLS network between multi-sites that allows VLANs.
Note that you must configure Hyper-v with static IP. In a multi-site cluster, you might want to tune the “heartbeat” settings, see http://go.microsoft.com/fwlink/?LinkId=130588 for details.

Cluster Selection: Node and File Share Majority (For Cluster with Special Configurations)
Quorum Selection: Since you will be configuring Node and File Share Majority cluster, you will have the option to place quorum files to shared folder. Where do you place this shared folder? Since we are talking about fully redundant and highly available Hyper-v Cluster, we have several options to place quorum shared folder.
Option1: Secondary Site
Option 2: Third Site

Hyper-V has been integral part of Windows Server 2008 and enhanced with great features in Windows Server 2012. According to Gartner’s magic quadrant Microsoft Hyper-v has been positioned in the leader category second to VMware. Combining Windows Server 2012 and System Center 2012 provide you a high performance Cloud Technology. Microsoft licensing model is highly flexible and charges only by physical processors and offer unlimited virtualization rights with Datacenter editions. With Hyper-v, your return on investment (ROI) increases as your workload density increases.
Pricing Comparison:
The pricing is based on the following assumptions:

Truth about VMware lies:
You don’t have to be Einstein to understand that VMware is in significant pressure from all sides. Hence they are misleading Cloud market with biased information. I would strongly recommend you to assess your business position, compare apple to apple before renewing/buying your next Cloud products. Though VMware is still no.1 player in Cloud Computing market but their fear is real that VMware loyal Customer is switching continuously to Microsoft Cloud Technology. A declining enterprise market leads them to spread the following one sided information.
1. VMware claim: VMware vSphere 5.1 can achieve an 18.9% higher VM density per host than with Microsoft Hyper-V.
Facts: In one of VMware’s own tests, when provided adequate memory to support the number of users the performance variance between vSphere 5.1 and Hyper-V R2 SP1 was only 2% (using 24VM’s).
2. VMware claim: Hyper-V performance is poor. If performance is important to you, choose VMware.
Facts: In reality, Hyper-V offers near-native levels of virtualization performance, for which there are multiple supporting proof points (including independent third party validations):
3. VMware claim: Hyper-V isn’t ready for the enterprise. It can’t handle the most intensive of workloads like VMware can.
Facts: Hyper-V offers near native levels of performance for key workloads, ensuring that customers can virtualize their mission critical, high-performance applications and workloads with confidence on Hyper-V. Additionally, a growing number of enterprise customers are running their businesses on Microsoft Hyper-V. Please read Microsoft Private Cloud success stories.
4. VMware claim: Hyper-V is lacking some of the key VMware features today. Features such as vMotion, HA, Memory Overcommit, DRS, Storage vMotion and Hot-Add are important features for us, and Hyper-V simple doesn’t come close.
Facts: Hyper-V R2 SP1 and System Center 2012 provide Live Migration, High Availability, Storage Live Migration, Dynamic Memory Allocation, Hot-Add and subsequent removal of storage.
5. VMware claim: VMware vSphere 5.1 is more secure than Hyper-V because it’s architecture and small code base.
Facts: Small footprint doesn’t equal a more secure hypervisor. Both vSphere and Hyper-V use the same memory footprint to run. The disk Footprint in ESXi 5.0 (144 MB) doubled from ESXi 4.0 (70 MB). Microsoft follows the rigorous, industry-leading Secure Development Lifecycle (SDL) for all its products. It is possible to achieve a 40-60% reduction in patches using Server Core based on historical data.
6. VMware claim: There is no virtual firewall in Hyper-V while VMware provides vShield Zones.
Facts: Windows Server 2012 also includes an integrated firewall with advanced security features. An old version of vShield Zones is included with vSphere 5.1 (details here) and vShield Zones has several limitations like every VM’s traffic passes through the Zones virtual appliances which slows down the traffic.
7. VMware claim: Microsoft doesn’t offer anything comparable to VMware Fault Tolerance.
Facts: VMware Fault Tolerance has limited applicability and severe limitations. It cannot function with:
8. VMware claim: VMware significantly support for Linux operating systems than Hyper-V.
Facts: In production environment, Hyper-v supports Microsoft Windows Server and Linux Server without modifying any guest operating systems or installing tools.
9. VMware claim: VMware supports broad applications, while Hyper-V does not.
Facts: Since VMware does not have certified logo program for any application, they are not in position to dictate which application are supported or not. On the contrary, every single application that achieves a logo for Windows Server can be run on guest operating system on a Hyper-V, and is therefore inherently supported. There are over 2500 ISV applications listed on Microsoft Pinpoint that work with Hyper-V. Truth is neither Microsoft nor VMware mention which application you can install on a guest operating systems. It’s completely up to you what you would like to run on guest operating systems.
10. VMware claim: VMware’s Site Recovery Manager (SRM) enables us to simplify our DR story, and provides us with a solution to not only perform a planned failover, but test it whenever we like. Microsoft simply can’t deliver an alternative to this.
Facts: System Center 2012 components like Data Protection Manager and Orchestrator can provide tailored DR solutions. Windows Server 2012 includes an inbox replication capability, Hyper-V Replica, at no cost.
11. VMware claim: Microsoft Hyper-v isn’t ready for Hoster or Service Provider.
Facts: Hyper-v has been adopted by service provider industry to host their own infrastructure and public cloud simultaneously on Hyper-v utilizing Microsoft Network Virtualization. Click here and filter using hosting and public cloud to find the list of hoster. Examples: hostway, softsyshosting , hyper-v-mart , geekhosting , BlueFire and many more.
12. VMware Claim: Hyper-v does not fully comply with Trunking, VLANs
Facts: Microsoft Network virtualization is more advanced than VMware standard Switch and DV Switch. Microsoft Hyper-v is fully compliant with 802.1q trunking, VLANs, VIP, networking Tunneling, multitenant IP management. VMware is catching up on network virtualization. Being in back foot VMware advertised to hire a PR professional to campaign on network virtualization.
Bottom-line: Why Selecting Hyper-v Over VMware
Other than cost savings, the following reasons why you should select Hyper-V and System Center 2012 over VMware vSphere 5.1
1. Built-in Virtualization: Hyper-V is an integral part of Windows Server 2008 and Windows Server 2012
2. Familiarity with Windows: In-house IT staff can utilize their familiarity and knowledge of Windows environment to deploy Hyper-v minimizing training cost and learning time.
3. Single Platform Cloud Management Technology: System Center 2012 enables you to manage physical, virtual, private and public cloud using a common console view for multi-hypervisor management, 3rd party integration and process automation, ability to manage applications via a single view across private and public clouds, and deep application diagnostics and insights.
4. Running common Microsoft Application: It is obvious that Microsoft application will run better on Hyper-v 2012. Still Microsoft has published third-party validated lab results that prove best-in-class performance for Microsoft workloads on Hyper-V.
5. Private, Public or Hybrid Cloud: Microsoft provides complete solutions for Private, Public or Hybrid cloud with next generation computing technology like IaaS, PaaS, SaaS.
6. Value for Money: Microsoft Private Cloud provides value for money. You will receive unrestricted virtualization license once you buy Windows Server 2012 Datacenter and System Center 2012.
7. Easy Migration: Convert VMware virtual machine to Microsoft Hyper-v virtual machine in few easy steps. See this link.
8. Single Vendor: Since your existing virtualization workload is mostly Windows Server, from vendor communication and contract management point of view, having Microsoft Hyper-v make more sense.
