Hyper-V 3.0 guide: Dissecting the next Microsoft hypervisor

Hyper-V 3.0 will be the first virtualization platform to truly challenge VMware, according to users and pundits who have tinkered with the next Microsoft hypervisor.

3.0 was first previewed at the Build 8 conference. Since then, virtualization enthusiasts have dissected the Hyper-V 3.0 and discovered several enhancements and additions, which include the following:

  • scalability upgrades for virtual machines (VMs), hosts and clusters;
  • redesigned live migration; and
  • support for extensible virtual switches.

For a closer look at Hyper-V 3.0’s under-the-hood changes, check out the following news, tips and articles on the next Microsoft hypervisor.

Hyper-V 3.0 to feature major virtualization scalability improvements
Hyper-V 3.0’s virtualization scalability improvements extend to virtual machines, hosts and clusters – a necessary step for Microsoft to remain competitive with VMware. In addition to more powerful virtual hardware, Hyper-V 3.0 will also natively support network interface card (NIC) teaming, which combines multiple NICs for greater bandwidth for traffic.

Hyper-V Replica: New VM replication tool for cost-conscious IT shops
For budget-conscious IT shops, Hyper-V Replica provides a viable disaster recovery option at no additional cost. It uses the Volume Shadow Copy Service to replicate and transfer VM snapshots to a secondary site. Copies are performed individually, so it may be cumbersome and impractical to replicate a large data center.

Spotlight on Hyper-V 3.0 high availability and redundancy
High availability and redundancy tops the list of changes to Hyper-V 3.0. The next Microsoft hypervisor will sport predictive failure analysis, which should reduce application downtime. It will also sport a re-architected live migration technology that will support Hyper-V 3.0’s larger clusters.

Hyper-V 3.0 shared-nothing live migration a boon for small shops
Shared-nothing live migration refers to the transfer of running VMs between servers without the need for shared storage or clustering. While not a replacement for traditional live migration, it’s an appealing feature for small businesses or branch offices that need to perform planned maintenance.

What the Cisco Nexus 1000V means to Hyper-V virtual networking
Hyper-V 3.0’s support of the Cisco Nexus 1000V is a boon to Cisco networking shops. Previously exclusive to VMware infrastructures, the virtual switch solves many network management and visibility problems that arise in a virtual environment.  Even though many IT shops don’t require that level of control over the networking stack that the Nexus 1000V provides, it’s another sign of Hyper-V’s enterprise readiness.
