Two New, Useful Server Virtualization Technologies

Posted on November 27, 2011 by

Current server virtualization technologies are more sophisticated and powerful than ever. This year, Citrix Systems and VMware introduced new hypervisors that offer a slew of useful features. Not to be outdone, Microsoft and Red Hat are also releasing latest updates to their server virtualization platforms.

For virtualization administrators, the next few years would be rather exciting, especially if their organizations are in the market for the latest hypervisor. By upgrading to new server virtualization, it is possible for IT departments to “virtualize” hardware-intensive applications and provision virtual hosts far more quickly, in a way that wasn’t possible before.

These are a couple of latest server virtualization technologies that could benefit your company:

  • Disaster recovery: Many administrators would be glad to use the new disaster recovery feature offered by VMware, which allows data duplication from primary to recovery site at the hypervisor level. Previous disaster recovery technique relies upon array-based duplication, which is somewhat inefficient in terms of storage used. Administrators can get significant flexibility by not using expensive storage at both sites; they simply need to run hypervisor hosts. This feature can even work with local storage and there are no shared-storage requirements. To ease failback and fallover, the feature uses custom configuration utility and an integrated run book. Finally, a small-sized business can realistically afford a reliable virtualization disaster recovery.

  • Hyper-V 3.0: It offers the ability to create more virtual CPUs and VM (virtual machine) memory. The Hyper-V 3.0 also features new VM replication and concurrent Live Migration. Last year, administrators appreciated the updated snapshot capability, which allow them to roll back to previous points after a failed application upgrade; however, there was a caveat: Administrators needed to shut down the VM after they deleted a snapshot and it caused repeated downtime. The Hyper-V 3.0 offers the same rollback capability, but because the AVHD file changes can be merged live into the Virtual Hard Disk, there would be no more downtime when administrators delete a point. As a whole, direct administrator interaction would be easier during an application upgrade. Hyper-V is Microsoft’s version of virtualization technology and it is available for free with Windows 2008 Server R2. Depending upon the version of Windows 2008 Server purchased users can run anywhere from a single to an unlimited number of Hyper-V copies, it allows users to save costs by postponing the purchase of additional equipments.
