Veeam

Veeam Backup & Replication v7 is Here!

Veeam just released their new flagship product Veeam Backup & Replication v7. The first release of the Veeam Backup & Replication was 5 years ago and Veeam did a lot of updates and improvements to their suite.

Innovation

v7 brings two innovations: Built-In WAN Acceleration and Backup from Storage Snapshots. While the “labels” of these features may not seem innovative, the technology behind them is. Our Built-In WAN Acceleration was developed from the ground up to work specifically with our backup file and data format. Our WAN acceleration is designed to help you save time and money when you need to get your backups offsite. Additionally, we’ll be bringing our WAN acceleration to replication jobs in a future release.

Backup from Storage Snapshots may seem like an “easy” task but once you take a look at what’s required in vSphere, you know it’s not. A standard approach to using storage snapshots on vSphere is to promote the snapshot to a LUN and temporarily attach it to a dedicated host…this operation alone can take up to 5 minutes and your backup hasn’t even started yet. Our engineers were able to get around this time-consuming task and further accelerate the backup by being able to leverage some key technology in vSphere and we know you’ll be impressed once you see it in action.

Features

v7 is packed full of features. We’ve already announced seven of the most disruptive features but the What’s New document contains many more. It seems that everyone has their “favorite” new feature in v7 although tape support seems to be close to the top for everyone. Personally, I’m excited about our vCloud Director support. We’ve been working on vCD support for a while but it was “not quite good enough” to make it into a previous release. I’m confident that our vCD support is second to none and when you see how easy it is to use, I’m sure you’ll agree. A big feature for our Hyper-V customers is the inclusion of Virtual Labs for Hyper-V. Now Hyper-V customers have access to SureBackup Recovery Verification, U-AIR and the On-Demand Sandbox capability that our VMware users have enjoyed for 3 years. There are a lot of other features and I’d love to hear what your favorite new feature is in the comments section.

System Center 2012 SP1 – Virtual Machine Manager support for VMware vSphere ESX Hosts

System Center Logo

As System Center 2012 SP1 was released, it officially supported VMware vSphere 4.1 and 5.1, there was no support for vSphere 5.0 in SCVMM 2012 SP1. Now since a lot of customer have requested this feature, Microsoft added VMware vSphere 5.0 to the supported list of vSphere versions. For those who didn’t know that, to manage VMware ESX Hosts you need a version of vCenter. Some months ago I made a blog post about how you can add your VMware infrastructure to Virtual Machine Manager.

Virtual Machine Manager now supports the following versions of VMware vSphere:

vCenter Server:

For System Center 2012 – Virtual Machine Manager:

  • VMware vCenter Server 4.1

For VMM in System Center 2012 SP1:

  • VMware vCenter Server 4.1
  • VMware vCenter Server 5.0
  • VMware vCenter Server 5.1

Virtual machine hosts and host clusters that run any of the following versions of VMware:

For System Center 2012 – Virtual Machine Manager:

  • ESXi 4.1
  • ESX 4.1
  • ESXi 3.5
  • ESX 3.5

For VMM in System Center 2012 SP1:

  • ESXi 5.0
  • ESXi 5.1
  • ESXi 4.1
  • ESX 4.1

Convert VMware vSphere Virtual Machines to Microsoft Hyper-V

Convert to Hyper-V Virtual Machine

On October 1st Microsoft released their Microsoft Virtual Machine Converter Solution Accelerator which includes Microsoft Virtual Machine Converter Solution Accelerator and the Microsoft Virtual Machine Converter Plug-in for VMware vSphere Client. This solution accelerator kit enables to covert Virtual Machines from VMware vSphere to Microsoft Hyper-V. I also tested the release candidate of Microsoft Virtual Machine Converter Solution Accelerator in July.

Some more information about the Microsoft Virtual Machine Converter features:

  • Converts and deploys virtual machines from VMware hosts to Hyper-V hosts including Hyper-V on Windows Server 2012. As part of the machine conversion MVMC converts the virtual disks attached to the source virtual machine. It also migrates configuration such as memory, virtual processor and so on from the source virtual machine to the converted virtual machine deployed on Hyper-V. It adds virtual network interface cards (NICs) to the converted virtual machine on Hyper-V.
  • Converts VMware virtual disks to Hyper-V based virtual hard disks (VHDs).
  • Supports conversion of virtual machines from VMware vSphere 4.1 and 5.0 hosts to Hyper-V.
    • Note   MVMC also supports conversion of virtual machines from VMware vSphere 4.0 if the host is managed by vCenter 4.1 or vCenter 5.0. You have to connect to vCenter 4.1 or 5.0 through MVMC to convert virtual machines on vSphere 4.0.
  • Offers fully scriptable command-line interfaces for performing virtual machine and disk conversions that integrates well with data center automation workflows and Windows PowerShell scripts.
  • Has a wizard-driven GUI, making it simple to perform virtual machine conversion.
  • Uninstalls VMware tools prior to conversion to provide a clean way to migrate VMware-based virtual machines to Hyper-V.
  • Supports Windows Server guest operating system conversion, including Windows Server 2008 R2, Windows Server 2008 and Windows Server 2003 SP2.
  • Enables conversion of Windows client versions including Windows 7.
  • Installs integration services on the converted virtual machine if the guest operating system is Windows Server 2003 SP2.

First you have to install the vSphere Client, the Microsoft Virtual Machine Converter Solution Accelerator and optional the Microsoft Virtual Machine Converter Plug-in for VMware vSphere Client. The Microsoft Virtual Machine Converter Plug-in for VMware vSphere Client allows you to convert a Virtual Machine directly from the VMware vSphere Client.

Here you can download the Microsoft Virtual Machine Converter Solution Accelerator.

To convert a Virtual Machine you have two options. First you can open the Microsoft Virtual Machine Converter. You can connect to your stand-alone ESX host or your vSphere vCenter server.

Microsoft Virtual Machine Converter Source

After you have connected to your vSphere environment, the Virtual Machine Converter will scan for Virtual Machines which can be converted, and you can select the VM you want to convert to Hyper-V.

Microsoft Virtual Machine Converter Source VMs

The second way is by using the Virtual Machine Converter Plug-in from VMware vSphere Client. You can right click on the Virtual Machine you want to convert and select Convert to Hyper-V virtual machine and this will launch the Virtual Machine Converter.

In both cases you have to connect now to the guest in the virtual machine.

Microsoft Virtual Machine Converter Source Connect

Select a Workspace where the virtual machine disk will be converted.

Microsoft Virtual Machine Converter Workspace

Configure the destination Hyper-V host.

Microsoft Virtual Machine Converter Desination Hyper-V host

After that you will get a summary and you can start the conversion.

Quick: Windows Server 2012 Hyper-V vs VMware vSphere 5.1

Windows Server 2012 Logo

Some months ago I wrote a lot of post about Hyper-V vs VMware vSphere. At this time I compared Windows Server 2012 Hyper-V Release Candidate with VMware vSphere 5.0. Since then a lot has changed Microsoft released the final version of Windows Server 2012 and VMware showed vSphere 5.1. I don’t have time to update every post I made but this should cover an overview about the numbers in both versions. This is mostly only about scale and a lot of customers will not hit any limit in both products, but still I think it is interesting to see how they compare.

There are a lot of other important arguments to use one or the other product, but I won’t cover this in this blog post. The data is from the Microsoft paper: Competitive_Advantages_of_Windows_Server_2012_Hyper-V_over_VMware_vSphere_5.1.pdf. In this PDF you can find more information about the advantages of Windows Server 2012 Hyper-V.
