Microsoft Hyper-V HA?

Towards the end of last year, I went to a technet event which was billed as a must see Virtualisation event. We’ll be showing how you can get virtual servers to failover with just Microsoft technologies they said.

And they did, with Virtual Server and Windows 2003 Clustering. It was a very big let down and it wasn’t even automatic. Most people had left before then end of the day, especially as we all thought they were going to show us Hyper-V. In fact, the Vista after hours event afterwards was by far the best part of the day.

Anyway, a few months later and Windows 2008 is out, Hyper-V is at RC and, well, Microsoft are still flogging the horse over clustering as being the solution:-

Yes, Windows 2008 clustering is much easier to configure, but I think the key point is towards the end – “all of the virtual machines will automatically restart to another node without user intervention”. Restart? I want them to carry on running, with, perhaps a small pause. It’s not live migration if the server’s not live!

Rumors of IBM or Cisco buying Citrix?

The markets are buzzing today on the rumor (here and here, for example), that either IBM or Cisco might try to buy Citrix. Of course the world is full of rumors, but there’s at least anecdotal evidence that people are listening to this one as Citrix’s stock moved up about 7% today, which is the biggest single-day move they’ve had in a while. (Although half-way through the day the stock has dropped about half that new value.)

Virtualisation Congress

Virtualization.info, the leading virtualisation news and analysis site since 2003 has announced the launch of Virtualization Congress (http://www.virtualizationcongress.com), the world’s first vendor independent virtualisation event, bringing together the industry’s biggest selection of virtualisation players, from the recognized leaders to the newest start-ups.

The conference, to be held at London’s ExCel, 14th-16th October, 2008, presents an ideal opportunity for current and prospective users of virtualisation technologies to hear directly from the companies at the cutting edge of their development; at the same time, in the same place for the first time ever.

MSCS (Microsoft Cluster Server) now supported in VMware 3.5 Update 1

Microsoft Cluster Server is supported with VMware ESX 3.5 Update 1. Support is similar to ESX 3.0.1 with the following additions:

  • Both 64 bit and 32 bit Windows 2003 guests are supported with MSCS.
  • Boot from SAN for VMs using MSCS is now supported.
  • Majority Node Set clusters with application-level replication (for example, Microsoft Exchange 2007 Cluster Continuous Replication (CCR)) is now supported.

For details regarding MSCS support, including a number of important restrictions, please see the document “Setup for Microsoft Cluster Service.” For information concerning supported storage arrays, refer to the Storage/SAN Compatibility Guide for ESX Server 3.5 and ESX Server 3i.

How to Implement Chargeback in a Virtualized Datacenter Using the Resource Consumption Model

(Source: VKernel) Most IT Professionals recognize the need for Chargeback, but are not sure how to implement a fair model. VKernel’s approach to doing Chargeback enables you to simply charge your customers for the resources (CPU, Memory, Storage and Network) they actually use. In this white paper, Vkernel will show you how to calculate exactly how much you should charge for 1Ghz of CPU, 1 GB of RAM, 1 GB of storage in your VMware ESX environment.
