Windows Server 2008 On-the-fly Memory Expansion

0

Since I had a Windows Server 2008 x64 Virtual Machine configured in my VMware Workstation and a Product Key from MSDN that I didn’t use I decided to try one of the cool features Server 2008 brings to a wide variety of new and even some old motherboards out there. I’m talking about its “Hot-add-Memory” feature.

So as I start this Virtual Machine up I have it configured with 1024MB (or 1GB) of RAM (click on image for original):

And now I want to expand this Server’s RAM without having to restart the whole system. I honestly don’t know if that’s that common of a use case out there in the real world but nevertheless it’s something that’s possible technology-wise and I think Linux has had it far earlier than Windows so here goes:

Hot-Swapping RAM is something that’s also included in more expensive versions of Server 2008 (like Datacenter) but in the Enterprise version which we have here all we can do is expand the RAM, not reduce it (see red box). So I pull the slider up to 2048 MB (or 2GB) to double my RAM and click “OK”.

What happened then wasn’t entirely what I was hoping for. VMware Workstation saved the Virtual Machine’s state first, then the Screen went black for a second and then it came back immediately and everything was exactly as I left it, so I guess this was just a precaution of VMware rather than something that was absolutely necessary. Then it took another few seconds for Windows to recognize the additional RAM and this was what I ended up with:

As you can tell from the red boxes in the first and the last picture (and the immense drop of the blue curve in the last picture) the RAM has been added without any shutdown of the system.

For Companies who need this, Windows Server 2008 Enterprise is definitely not too expensive to buy although it could be cheaper of course. This feature is not exclusive to the latest and greatest hardware either so the additional cost in hardware shouldn’t be too high either. Contrary to a Linux Server it offers an Administrator the possibility of deploying Microsoft Exchange Services natively and it enables them to install the wide variety of Software that’s out there for Windows.

HP iPAQ Review – Part 1: Introduction & Similarities

So I want to kick off my review with a short introduction to the devices and what they have in common. No personal opinion in this post.

The Voice Messenger (on the left in my last post) is a Smartphone in the shape of an ordinary mobile phone, so it is compact, yet with Windows Mobile it has a quite sophisticated Operating System on top of it for a rather small device.

The Data Messenger is a full-featured Pocket PC with a QUERT-Keyboard for landscape-operation and a touch-screen which can either be used with your finger or the included Stylus.

The things they have in common at first and second sight would be the following:

  • Both have the exact same Status-LED to the upper left of their screens.
  • The navigation is handled by a circular Hard-Button with a tiny Trackball in the middle.
  • The Buttons and connectors on the sides are the same. Read my next posts for details.
  • On top they have a Mute-Switch.
  • They both have a 3.1 Megapixel autofocus camera with LED-flash.
  • Furthermore you can of course see that they both have the same optical appearance concerning their enclosure and design.

Stay tuned some more for detailed Reviews of each device and a personal opinion. Hope I didn’t miss any similarities.
