About

You arrived at the weblog of Geert Baeke. I am a technology consultant for a company called Xylos (Belgium). I mostly work with Microsoft technologies such as Windows, Active Directory, Exchange, Sharepoint, MSCS, and more. I am also actively busy with VMware's products, focussing on VMware ESX.

System Center Virtual Machine Manager (SCVMM) and VMware

The SCVMM product is available today to manage Virtual Server 2005 R2 SP1. But somewhere this year, another version of SCVMM (vNext) will be available that also manages Hyper-V and VMware VI3.

What you should know about this is that SCVMM does not replace VirtualCenter. In fact, SCVMM requires VirtualCenter because it uses the VI3 APIs of VirtualCenter to do all of its work. If you have multiple VirtualCenter servers, SCVMM will be able to talk to all of them to enable management across all instances. It seems a bit too hard for Microsoft to talk to the ESX servers directly which surprises me because there are APIs to do that.

I am not sure if using SCVMM together with VirtualCenter is a compelling scenario. Sure, SCVMM's PowerShell functionality is cool but VMware itself is hard at work to get their VI PowerShell launched. VI PowerShell will beta this month and from what I have already seen it works very well.

Another SCVMM function, intelligent placement, is also something that has been available for a while on VI3. I continuously hear people say that this is a feature that SCVMM vNext will bring to VI3 and that is just incorrect. See also this article about this common misconception.

The library feature is not that interesting either because you can easily store ISOs, floppy disk images and virtual machine templates on VMFS or NFS datastores. SCVMM does provide a nicer GUI to work with those assets but that is not something that justifies an extra management tool.

I do see some benefit in the integration of SCOM 2007 with SCVMM vNext especially if Microsoft were to release a management pack for VMware VI3. Performance information from ESX hosts and virtual machines could then be fed into SCCM vNext to improve VMotion recommendations, intelligent placement calculations and so on. I don't except this will happen soon but today at the Microsoft TechDays in Ghent, a Microsoft employee told us that we should expect some big announcements around the timeframe of the Management Summit. Will there be more VMware-related integration? Time will tell...

So although I think SCVMM is great for Virtual Server and Hyper-V deployments, I don't think it is very useful in a VMware environment. But maybe you have a different opinion so let me know what you think.

Are you running at 80-90% storage utilization and are getting ready to spend millions on new hardware upgrades? If so please take the time to read about Fairway Consulting Group’s Total Virtual Solution. FCG has provided their solution to companies like: Embraer, IKEA, Kingston Technologies, Sage Software, The Knight Foundation, Virginia Tech (currently) to name just a few. How does virtualization work you are probably wondering. Through virtualization, we take your current server environment and consolidate those servers into virtual machines (VM's); reducing the number of physical servers that are needed by an 8:1 ratio.

When it comes to storage utilization, the industry average is 35%; leaving you with 65% of your storage wasted and a very poor ROI. Our DataCore solution takes your current storage and maximizes your utilization through a process called "thin provisioning". Thin provisioning changes the way storage is accessed by moving away from a “commit-on-allocate” model to a more efficient “commit-on-write” model, therefore greatly reducing the amount of storage hardware required which directly affects your bottom line.

If energy conservation or "green" sustainability is a concern for your business, then the FCG Total Virtual Solution is exactly what you are looking for in order to dramatically lower your electrical needs, as well as significantly reducing current and future hardware maintenance. Our Pano Logic units run in conjunction with the virtual platform and replaces your current 150 watt desktops with a solid state device that uses only 5 watts; saving your department possibly hundreds of thousands of dollars per year in electrical costs alone. I could go on and on about how virtualization is the wave of the future, but I ask only that you give us the opportunity to provide a webinar or conference call with one of our engineers to discuss how FCG can put your business on the cutting edge of Information Technology.
