We've got about 14 SQL and/or other production database servers running in VMWare, plus 3 - 4 times that many for Dev/Test environments with no issues. We do have our main Siebel production servers running on physical servers, but all the periphery Siebel apps are virtual. Some of the production SQL apps that we have virtual are Project Server, SharePoint, a POS app etc. On 7/22/08, John Hornbuckle <[EMAIL PROTECTED]> wrote: It's a program to use in school libraries for checking books in and out.

We're a small district with small schools, and no app we've ever run on a server has come anywhere close to fully utilizing the hardware. That's one of the reasons I want to virtualize more. If the app will run on an XP "server" with a Pentium 4 processor, I can't imagine that it would be overly demanding. But they do say they require RAID 1 or 5, so they must be counting on a fair amount of I/O activity. But I wonder, what exactly is "high" I/O when it comes to figuring out if something will run okay on a virtual server?

Why would a product not work on a virtual server, well, one that is high I/O, as in a database server would possibly not work. What application specifically are you looking at that says this? We've used virtual servers for probably 5 years now, and we've always taken the approach that we will try it on a virtual server and if it doesn't work, then go to physical. So far, we're doing really good with that approach. 99% of what we've tried on a virtual server has worked. Now to counter that, we have always looked at what the application will be doing, evaluated the requirements and load, and made the decision on whether or not it's a good candidate for virtualization or not a good candidate for virtualization. Now with that said, I do have a caveat, I've never used Hyper-V and probably will never use it, we've been VMWare since we started with virtual server, first GSX now the latest release of ESX. So, I can't say how Hyper-V utilizes system resources compared to ESX.....

Now, this software doesn't have any special hardware requirements. Processor requirements are modest, as are requirements for RAM and storage space. And yet, the requirements explicitly say, "Microsoft Windows Server 2008 Standard or Enterprise without Hyper-V" (if Server 2008 is the OS--it also supports Server 2003, XP, or Vista as the server OS). As I've mentioned before, I'm brand new to server virtualization. I'm playing with Hyper-V right now for the first time. So, I'm sure I'm missing something. Why, exactly, would a product like this not work on a virtual server?
