VMware Ends Support for 3rd Party Virtual Switches

This post on reddit appears to intimate that VMware is closing its API for virtual switches to all parties, including its long-standing networking partner Cisco. When I first read the post, I thought the move was a retrograde step by VMware and another veiled dig at its ecosystem. The post links to an official blog post on the VMware site stating that moving forward, VMware “will have a single virtual switch strategy that focuses on two sets of native virtual switch offerings – VMware vSphere® Standard Switch and vSphere Distributed Switch™ for VMware vSphere, and the Open virtual switch (OVS).”

From a numbers perspective, this makes sense, as about 99% of its customers are already using this single model of standard virtual switch and/or distributed virtual switch. It does fall into what research is stating. We at TVP Strategy applaud any attempt at reducing complexity, but we do find the fact that this announcement was hidden away in a blog post obtuse in the extreme.

Virtualization Backup: Agent or Agent-less?

But what if you could get the benefits of your existing backup tools (such as Tivoli) but gain the power and advantages of using all the possibilities within the virtual environment. For VMware vSphere this is possible using the Pancetera backup tools.

Veeam SureBackup

Veeam has introduced a new technology named SureBackup. SureBackup is designed to not only use Veeam’s Backup technology to backup your virtual machines (VMs) but will also test the restoration of each of these VMs to ensure that they at least boot and at most the applications involved are actually running within the VM.

This is a great improvement over current backup methodologies which consists of by hand testing of only a scant number of virtual machines to ensure restorations result in boot-able virtual machines. The full test of restorability almost always happens during a disaster situation when everyone is under a fair amount of pressure. The current backup and restoration testing follows this path:

  • Quiesce the virtual disk employing VSS or other technologies
  • Backup the virtual disk
