Windows Server 2022 Preview License Keys

Windows Server 2022 Preview License Keys

To test the Windows Server 2022 Preview builds you need to register as a Windows Insider, log in and download the ISO or the VDHDX. With the ISO for a clean install or an upgrade, you need the Windows Server 2022 preview license keys. I have listed these below. Do note that since Windows Server 2022 Preview build 20334 those keys have changed.

Get the preview builds and start testing!

As I build or upgrade some VMs in the labs weekly I decided to put these keys in a little blog post for me to find them easily. I intend to update this post if and when new keys are needed. Do not worry, these are public, so I do not break any license agreement here.

A short reminder that this is prerelease software

First of all, I will quote Microsoft here.

Windows Server Insider Preview builds may be substantially modified before they are commercially released. Microsoft makes no warranties, express or implied, with respect to the information provided here. Some product features and functionality may require additional hardware or software. These builds are for testing purposes only. Microsoft is not obligated to provide any support services for this preview software.

Secondly, I remind you that Microsoft loves that you test the builds and provide feedback. Just do not use this for anything in production. That’s it folks, happy testing folks.

Hyper-V Technical Preview Live Migration & Changing Static Memory Size

I have played with  Hot Add & Remove Static Memory in a Hyper-V vNext Virtual Machine before and I love it. As I’m currently testing (actually sometimes abusing) the Technical Preview a bit to see what breaks I’m sometimes testing silly things. This is one of them.

I took a Technical Preview VM with 45GB of memory, running in a Technical Preview Hyper-V cluster and live migrate it.  I then tried to change the memory size up and down during live migration to see what happens, or at least nothing goes “BOINK”. Well, not much, we get a notification that we’re being silly. So no failed migrations, crashed or messed up VMs or, even worse hosts.

It’s early days yet but we’re getting a head start as there is a lot to test and that will only increase. The aim is to get a good understanding of the features, the capabilities and the behavior to make sure we can leverage our existing infrastructures and software assurance benefits as fast a possible. Rolling cluster upgrades should certainly help us do that faster, with more ease and less risk. What are your plans for vNext? Are you getting a feeling for it yet or waiting for a more recent test version?

Using RAMDisk To Test Windows Server 2012 Network Performance

I’m testing & playing different Windows Server 2012 & Hyper-V networking scenarios with 10Gbps, Multichannel, RDAM, Converged networking etc. Partially this is to find out what works best for us in regards to speed, reliability, complexity, supportability and cost.

Basically you have for basic resources in IT around which the eternal struggle for the prefect balance finds place. These are:

  • CPU
  • Memory
  • Networking
  • Storage

We need both the correct balance in capabilities, capacities and speed for these in well designed system. For many years now, but especially the last 2 years it very save to say that, while the sky is the limit, it’s become ever easier and cheaper to get what we need when it comes to CPU, Memory. These have become very powerful, fast and affordable relative to the entire cost of a solution.

Networking in the 10Gbps era is also showing it’s potential in quantity (bandwidth), speed (latency) and cost (well it’s getting there) without reducing the CPU or memory to trash thanks to a bunch of modern off load technologies. And basically in this case it’s these qualities we want to put to the test.

The most trouble some resource has been storage and it has been for quite a while. While SSD do wonders for many applications the balance between speed, capacity & cost isn’t that sweet as for our other resources.

In some environments were I’m active they have a need for both capacity and IOPS and as such they are in luck as next to caching a lot of spindles still equate to more IOPS. For testing the boundaries of one resource one needs to make sure non of the others hit theirs. That’s not easy as for performance testing can’t always have a truck load of spindles on a modern high speed SAN available.

RAMDisk to ease the IOPS bottleneck

To see how well the 10Gbps cards with and without Teaming, Multichannel, RDMA are behaving and what these configuration are capable of I wanted to take as much of the disk IOPS bottle neck out of the equation as possible. Apart from buying a Violin system capable of doing +1 million IOPS, which isn’t going to happen for some lab work, you can perhaps get the best possible IOPS by combining some local SSD and RAMDisk. RAMDisk is spare memory used as a virtual disk. It’s very fast and cost effective per IOPS. But capacity wise it’s not the worlds best, let alone most cost effective solution.

I’m using free RAMDisk software provided by StarWind. I chose this as they allow for large sized RAMDisks. I’m using the ones of 54GB right now to speed test copying fixed sized VHDX files. It install flawlessly on Windows Server 2012 and it hasn’t caused me any issues. Throw in some SSDs on the servers for where you need persistence and you’re in business for some very nice lab work.

You also need to be aware it doesn’t persist data when you reboot the system or lose power. This is not an issue if all we are doing is speed testing as we don’t care. Otherwise you’ll need to find a workaround and realize those ‘”flush the data to persistent storage” isn’t full proof or super fast, the SSDs do help here.

You have to register but the good news is that they don’t spam you to death at all, which I find cool. As said the tool is free, works with Windows Server 2012 and allows for larger RAMDisks where other free ones are often way to limited in size.

It has allowed me to do some really nice testing. Perhaps you want to check this out as well. WARNING: The below picture is a lab setup … I’m not a magician and it’s not the kind of IOPS I have all over the datacenters with 4 Cheapo SATA disks I touched my special magic pixie dust.

With #WinServ 2012 storage costs/performance/capacity are the only thing limiting you  http://twitter.yfrog.com/mnuo9fp #SMB3.0 #Multichannel

Some quick tests with a 52GB NTFS RAMDisk formatted with a 64K NTFS Allocation unit size.

I also tested with another free tool from SoftPerfect ® RAM Disk FREE. It performs well but I don’t get to see the RAMDisk in the Windows Disk Management GUI, at least not on Windows Server 2012. I have not tested with W2K8R2.

Prepare For Windows Server 2012 This Fall

With the academic year in full swing and no lack of material we need to learn and study Microsoft is giving you a helping hand by providing a huge pool of resources. There’s TechNet, Evaluation software but also the Microsoft Virtual Academy.

To reward you for your hard work you get a cinema ticket to go relax at the movies. Click on the banner for more information on this.

The nice thing about the Microsoft Virtual Academy that you can do study the modules at your own pace and at your own moment of choosing. Combine this with TechNet Virtual labs and you have a lot of resources at your finger tips to learn even more even if you don’t have the room or resources to build a (home) lab.

If all that technology left you wanting to get some hands on with Windows Server 2012 you can also register for an IT Camp. There should be some more of them coming I’ve read on the site. With Mike Reseler  (@MikeResseler) & Arlindo Alves@aralves) delivering those IT Camps you’ll be in good hands. Happy studying and have fun at the movies Winking smile
