Heading to the MVP Global Summit 2016

It’s that time of the year where I’ll be making my way to Redmond (Washington, USA) to attend the MVP Global Summit 2016.

It’s going to be and interesting one as after 2 years of Technical previews Windows Server 2016 went RTM  last September and is generally available. Our hardware partners are selected for best value and that means early and good support for new releases of Windows. Dell, Emulex, Intel and Mellanox delivered and that means we can already share our first real life experiences around the finished product with Microsoft.

We’ll also be talking shop about future directions and provide feedback on what we want to see happen and need. Next to Windows (which is so much more than “just” an operating system nowadays) we have a stake in SQL Server  2016 and Azure. Azure in all it’s offerings, SAAS, PAAS, IAAS – both public and hybrid use cases.

To do so we need to get there first so we’ll hop on a Boeing (hey I’m flying to Washington, kind has to be a Boeing right?) for long haul a flight to Redmond and go talk shop all week long from early dawn at breakfast to night caps in downtown Bellevue with friends and colleagues.

Next to pure technology we also talk about business challenges and opportunities. The best positioned organizations are the ones where the technical people have taken and been given the opportunity to lead. I know it’s scary for some managers that feel threatened by this but when the techies lead the IT side of the business the rest can can focus on the business and avoid the costly mistakes that I see so many make today. Most organizations have failed at getting business people up to speed on IT. I’ve seen a lot of successful organizations let technical people show how the business how to thrive in a mobile and cloud first world. It just makes sense to let your experienced and talented technical people take the lead. Don’t think for one second that they’re just janitors mopping the floor in an outdated server room when not busy handling the “other” facilities. Do that and you will fail painfully. Put away your politics, fears, long term gigantic projects and learn to let fast, inexpensive, simple, small technology solution rule in a federated world to maximize time to market, results and flexibility. If you don’t let go of centralized, long term, overly complex technology projects and old school enterprise solutions – where everything is held by back by everything else – you’ll fail, lose vast amounts of money and time. Don’t!

In Place upgrades of cluster nodes to Windows Server 2016

You will all have heard about rolling cluster upgrades from Windows Server 202 R2 to Windows Server 2016 by now. The best and recommend practice is to do a clean install of any node you want to move to Windows Server 2016. However an in place upgrade does work. Actually it works better then ever before. I’m not recommending this for production but I did do a bunch just to see how the experience was and if that experience was consistent. I was actually pleasantly surprised and it saved me some time in the lab.

Today, if you want to you can upgrade your Windows Server 2012 R2 hosts in the cluster to Windows Server 2016.

The main things to watch out for are that all the VMs on that host have to be migrated to another node or be shut down.

You can not have teamed NICs on the host. Most often these will be used for a vSwitch, so it’s smart and prudent to note down the vSwitch (or vSwitches) name and remove them before removing the NIC team. After you’ve upgraded the node you can recreate the NIC team and the vSwitch(es).

Note that you don’t even have to evict the node from the cluster anymore to perform the upgrade.

I have successfully upgrade 4 cluster this way. One was based on PC hardware but the other ones where:

  • DELL R610 2 node cluster with shared SAS storage (MD3200).
  • Dell R720 2 node cluster with Compellent SAN (and ancient 4Gbps Emulex and QLogic FC HBAs)
  • Dell R730 3 node cluster with Compellent SAN (8Gbps Emulex HBAs)

Naturally all these servers were rocking the most current firmware and drives as possible. After the upgrades I upgraded the NIC drivers (Mellanox, Intel) and the FC drivers ‘(Emulex) to be at their supported vendors drivers. I also made sure they got all the available updates before moving on with these lab clusters.

Issues I noticed:

  • The most common issue I saw was that the Hyper-V manager GUI was not functional and I could not connect to the host. The fix was easy: uninstall Hyper-V and re-install it. This requires a few reboots. Other than that it went incredibly well.
  • Another issue I’ve seen with upgrade was that the netlogon service was set to manual which caused various issues with authentication but which is easily fixed. This has also been reported here. Microsoft is aware of this bug and a fixed is being worked on.

Hello there! Carsten Rachfahl and I have a new Hyper-V Amigo showcast out. In this Hyper-V Amigo Showcast Episode 11 we talk about Hyper-converged Storage Spaces Direct in Windows Server 2016 installed.

Carsten has a nice demo system to play with and we have some fun playing with it. We’ll see the outstanding performance S2D can deliver and how resilient is. On top of this we also talk about Distributed Storage QoS, Node Isolation and Node Fairness.

The show some crazy performance numbers and even turn 2 of the 4 nodes off. While playing with the Cluster we see also some new Features like Distributed Storage QoS, Cluster and VM Isolation and Node Fairness.

Enjoy!
