My Thoughts On IT…

Brian Lewis's Thoughts on all things Information Technology related

Ok, I have had the weekend to play with my Windows Server “8” Beta code and it Rocks! If you haven’t grabbed the code yet you can get it here: http://aka.ms/server8cp

If you are looking at virtualization or building a private cloud this new version of Hyper-v totally rocks! Here are just a few of the new limits in Hyper-v. I will discuss and demonstrate some of the new features in future posts.

Windows Server “8” Beta Hyper-V Scale Metrics:

  1. 160 logical processors per host
  2. 1024 VMs per host
  3. 64 nodes per cluster
  4. 4000 VMs per cluster
  5. 32 virtual processors per VM
  6. 1 TB memory per VM
  7. 64 TB per VHDX file

Yes folks…

Up to 1 TB of memory PER virtual machine. No taxes, no entitlements, no penalty for buying a large scale up server.

Up to 64 TB per VHDX. No, that’s not a typo. That’s really 64 TB per VHDX. You’ll likely run out of physical storage long before you hit any limits in Hyper-V.

In addition, these scalability metrics lead the industry:

  • VMware vSphere 5.0 support up to 32 nodes in a cluster. Windows Server 8 Hyper-V supports 64 nodes. (2x over VMware)
  • VMware vSphere 5.0  supports virtual disks up to 2 TB in size. Windows Server Hyper-V 8 supports virtual disks up to 64 TB in size (32x over VMware)
  • VMware vSphere 5.0 supports 3,000 VMs per cluster.  Windows Server 8 supports 4,000
  • VMware vSphere 5.0 supports 512 VMs per host.  Windows Server 8 supports 1,024

While VMware supports up to 1 TB of memory per VM, you have to purchase vSphere 5.x Enterprise Plus ($3,500 per processor) and then purchase memory entitlements (taxes) to achieve this goal. Hyper-V 8 has no such tax or entitlement. Such taxes are an anathema to our customers. Every version of Windows Server 8 that ships with Hyper-V will support up to 1 TB of memory per VM.

The Windows “8” client wasn’t the only piece of excitement in the Windows 8 world this week!

The official Windows Server “8” beta release also landed this week and there is so much cool stuff to learn about and share from storage management enhancements to web server improvements to a version of Hyper-V that’s going to blow your mind in what it can do.  Here’s all the info you need to be in the know:

untitledToday is a big day for the Windows team. At Mobile World Congress in Barcelona, Spain a few moments ago, we unveiled the Windows 8 Consumer Preview to our partners and press. Based on a broad range of feedback, we have made over 100,000 code changes and the Consumer Preview represents a refined product ready for broad and daily usage by those of you willing to test a pre-release OS. You can download the Consumer Preview starting now at http://preview.windows.com.

On this page there is a tool witch will evaluate your pc and let you know what will work and if there are things that may not work. Then it will get you a product ID. Lastly it will download the ISO and help you burn a CD or put it on a USB key.

There are other ways to get the software. Here is the public Windows 8 Consumer Preview ISO images page: http://windows.microsoft.com/en-US/windows-8/iso

Another way to get the code for customers who have a TechNet or MSDN subscription is to download it from the Subscribers Download section.

Today is an exciting day! (for geeks like me) –Enjoy!

For a great overview of the new OS checkout this page: http://windowsteamblog.com/windows/b/windowsexperience/archive/2012/02/29/introducing-windows-8-consumer-preview.aspx

backgroundWindows Vista and Windows 7 had a new integration that let you integrate programs into the desktop. These were called desktop gadgets.

In Windows 7 if you right click on the desktop select “Gadgets” then a Window with a few built in gadgets comes up. At the bottom right corner is a link that says “Get more gadgets online”. In the past this took you to the Windows Live Gallery with hundreds of gadgets that Windows enthusiasts built. Now it takes you to a page that lists the top 30 gadgets.

I wrote a gadget up there called the RDP Gadget for Windows. The reason I wrote it is because I wanted something that gave me a quick way to remote into my servers that I managed and I didn’t like the other things that were out there. While it wasn’t the most amazing software ever written, I do get request from time to time from people who are looking for it.

So with that in mind I put up the install in my SkyDrive here: https://skydrive.live.com/?cid=c701040168c26972#cid=C701040168C26972&id=C701040168C26972%21134

The file is called RemoteDesktop.gadget. Download it. Double click it and it will install.

If you want to see the source code just change the extension from .gadget to .zip and open it. It is written in html and javascript.

Want a sweet new wallpaper for your desktop? Here is one to support the Microsoft “Smoked by Windows Phone” add campaign. Just click on the photo below to get the full size graphic. Then right click and download photo. Smile

3056_hyper-v2-large-msg_thumb_0D8890ECIn my webcast on Hyper-V, this past Wednesday, I had a question about Hyper-V and how Hyper-threading effects that.

The current version of Hyper-V in Server 2008R2 we recommend an 8 to 1 consolidation ratio for virtual processors to logical processors and a maximum of 384 virtual machines on a single host (whichever is lower).  Intel, SMT (aka Intel Hyper Threading) is available on many current CPUs, so how does this effect performance in a VM and how is VM consolidation ratios affected? 

The Hyper-V team has reviewed performance data showing that enabling SMT may have a positive impact on overall performance when running under Hyper-V.

For the purposes of capacity planning with Hyper-V, you should use the number of physical processor cores on the machine, rather than the number of execution threads. The Windows Task Manager (and many other tools) show the number of execution threads, so care should be taken when determining the number of processor cores in a system.  For example, if I have a quad core CPU with hyper threading the taskmgr will show 8 CPUs. So for planning use the actual number of cores and then you can increase consolidation ratios after testing.

While the addition of SMT threads may enhance overall performance under Hyper-V, the additional performance is not a constant factor. The additional performance is heavily dependent on the target workload, overall machine utilization, and other factors.

Generally speaking, you can utilize the additional performance of SMT threads in two ways:

For computationally intensive workloads, you may benefit from increasing the number of Virtual Processors (VPs) assigned to a VM. For example, a 1 VP VM may be able to do more work if you assign it two VPs. Alternatively, or in combination with the above, if keeping the VPs per VM constant, you may be able to increase your consolidation ratio.
