Hyper-V is easy to learn, and as a Microsoft product, saves you a lot of trouble if you operate in a Windows only environment. A money saving feature is that you can run virtual machines without paying for extra server licensing. Features that Hyper-V 2012 has that some other hypervisors typically don’t are:
· Live migration of a server to another with no shared data storage between the two
· Many resiliency/availability features such as off site server replication
· Multiple operating systems can reside on an independent Hyper-V server and be managed as part of the same environment
· Most important features have been bundled in a simple and inexpensive package with the potential to save companies substantial expense while offering easy to use controls that will not confuse staff or waste valuable time
Hyper-V’s main competitor, VMware’s vSphere, is the lead hypervisor product. Hypervisor technology is employed by both public and private clouds. 90% of those polled in a Virtualization Management Survey use vSphere as their main hypervisor platform. The second most popular platform was Microsoft Hyper-V with only 14% using it as their primary production hypervisor.
Microsoft’s worldwide industry director recently declared the company’s intent to take a leading role in virtualized infrastructure. Windows Server 2012 with Hyper-V is a scalable virtualization platform suitable for businesses of all sizes. It can provide organizations with operations which are both efficient and economical. Microsoft represents Hyper-V as a reliable platform suitable for mission critical operations. Some of the pluses of Hyper-V 2012 are expanded support for both memory and host processors. Up to 64 processors and 1 terabyte of memory, a new virtual hard disk format and 64 terabytes disk capacity are the latest features. An organization can continue using servers they already have and use Windows Server 2012 with Hyper-V to utilize the latest hardware technology.
VM technology provides VM scalability, enhanced performance, network virtualization, NIC teaming, Hyper-V Replica for disaster recovery, and shared nothing live migration. Microsoft admits to having lagged behind VMware in the past, but with new Hyper-V 2012 it offers many improvements. Microsoft believes its new Hyper-V can deliver hosting providers the cloud computing and cloud archiving infrastructure they need at a significantly lower price than that of VMware, claiming to equal or surpass VMware functionality and cost in features ranging from the higher upper limit of virtual CPUs per VM- to greater VM memory capacity - to maximum virtual disk capacity.
Most infrastructure as a service providers prefer reliability over flashy supersize capacity features. Hyper-V 2012 is designed for redundancy, reliability and secure data backup to appeal to small to medium size providers.
Microsoft Hyper-V Server 2012 is a server virtualization product that enables workload consolidation, improving server utilization and thus reducing costs. It provides a Virtual Desktop Infrastructure, allowing a Windows client operating system to run on a datacenter virtual machine. Users can access this via a PC, thin client and other client devices. Benefits gained are a complete windows environment run from a datacenter, cost effective desktop functionality, reduction of administration overhead, more storage options and dynamic resource allocation.
According to Server Watch, VMware claims that they can get 300,000 IOPS from a single VM. Windows Server 2012, is getting 985,000 IOPS from a single VM. VMware has been the virtualization leader up till now but clearly considers Hyper-V 2012 a threat.
