Hyper-V is Microsoft’s virtualization platform that allows you to run multiple virtual machines on one physical host. Hyper-V is by far the most exciting and game changing aspect of Server 2012 that Microsoft has brought to the table.

Check out last week’s installment on failover clustering.

Joining The Fray

Microsoft has thrown down its gauntlet in the realm of virtualization and it is a very big gauntlet. Microsoft has created a Hypervisor that understands the growing needs of virtualization and the growing need for data. Hyper-V in Server 2012 allows for the largest capacity of Processors, Physical RAM, and Virtual Storage.

Un-limiting Limits

The limits of Hyper-V are, to the point of being beyond comprehension, because of the size of the Virtual Machines you can create. For the capacity of the host for the VMs is 320 Logical Processors, four Terabytes of Physical Memory, 2048 Virtual CPUs per host, and 1024 active VMs per host. The level of capability is staggering. The VMs within the host are capable of the following limits: 64 Virtual CPUs per VM, and one Terabyte of memory per VM, and 64 Terabyte Virtual HDD using the new .VHDX format for Virtual HDD.

Within Hyper-V there is also the capability of Virtual Fibre Channel. Given the amount of data that Hyper-V is capable of, it is important to remember that there may come times that large amounts of data need to be moved and need to be moved more quickly. If you have a Fibre Channel infrastructure Hyper-V allows you to take advantage of allowing the VMs to connect directly to that Fibre Channel infrastructure.

Live Migration

Live Migration and Shared-Nothing live migration are another nice feature in Server 2012 Hyper-V. Live Migration was introduced in Server 2008 R2. Live migration allows you to move a running VM to another location without downtime or a need to stop parts of your infrastructure to make it happen. The newer version of Live Migration also supports a faster connection of up to 10 Gigabit. You can also use Shared-Nothing Live Migration, which is the ability to move a live running VM to another Hyper-V host without the two Hyper-V hosts sharing any storage.

The capacity and flexibility of Hyper-V are some of the many ways that Microsoft is changing their focus to look to the future of computing and what datacenters in this modern world will look like.

Given the capabilities discussed above, the vision for a company’s IT needs, desires, and capacity drastically change in regards to what kind of space and resources are needed to support your business needs. What used to take up an entire room can now be harnessed in a much smaller package given the host machines are equipped and set up correctly to handle the needs of a company and also grow as the business grows.
