Move multipe Hyper-V Virtual Machines with Live Storage Migration via Windows PowerShell

Well I was working in on a Private Cloud Deployment where we had some temporary storage for our Hyper-V Virtual Machines and after we got the right storage ready, which was btw a Windows Server Scale-Out File Server Cluster running with Storage Spaces and DataON JBOD chassis, we had to migrate the storage of all virtual machines running on our Hyper-V hosts. Since Windows Server 2012 offers Live Storage Migration which allows us to move the Virtual Machine to a different storage location without downtime we would use that. But if you have to move around 20 virtual machines you think twice if you want to move that via the Hyper-V Manager GUI or Windows PowerShell.

Here is a pretty simple PowerShell foreach loop which moves the storage of all virtual machines running on the Hyper-V host.



System Center Universe Europe

Speaking at System Center Universe Europe 2015

I already had twice the honor to speak at System Center Universe Europe, the first time at SCU Europe 2013 in Bern and the second time at SCU Europe 2014 in Basel. As I mentioned in a blog post a couple of months ago, System Center Universe Europe 2015 is just around the corner and you still can get tickets!

At SCU Europe 2015 I have again the great honor to speak together with some other great community leaders about the Microsoft Cloud and Datacenter solutions.

My Sessions at SCU Europe 2015:

Nano Server the next generation of Cloud Server in your datacenter

In this session we will walk you through how Nano Server is changing the fundamental way we look at fabric Servers and workloads. Nano Server will change the way we build servers and solve fundamental challenges which we have encountered over the pact years embracing cloud fundamentals. Speaking together with Kristian Nese (Microsoft MVP)

What’s new in Windows Server 2016 for Hyper-V

With Windows Server 2016 Microsoft adds again exiting features to its Virtualization Platform. Learn in this session what Shielded VMs, Rolling Cluster Upgrades, Storage Spaces Direct, Hyper converged, PowerShell Direct, Windows Containers, and much more is and how you can profit from these new technologies. Speaking together with Carsten Rachfahl (Microsoft MVP)

Azure Site Recovery, 365 days later

Disaster Recovery, everyone talks about it – everyone claims they have it! But does it really work as expected?! Join us in the session about Azure Site Recovery, the business continuity service from Microsoft for all cloud platforms, on-premise – service providers – public cloud. You will learn how your company or customers can use ASR in their datacenter and which new scenarios have been added in the last 365 days, since we presented this topic at SCU 2014. Speaking together with Michel Lüscher (Microsoft)

There are a lot of other great sessions as well, so make sure you get your ticket!

List of Recommend Hotfixes and Updates for Hyper-V Network Virtualization (HNV)

I already made some post where I list the websites to recommended hotfixes and updates for Clusters, Hyper-V and File Server such as the Scale-Out File Server for Hyper-V over SMB. Now Microsoft also has an official list for Recommended hotfixes, updates, and known solutions for Windows Server 2012 and Windows Server 2012 R2 Hyper-V Network Virtualization (HNV) environments. Which will list hotfixes for Hyper-V, Windows Server and System Center related to Network Virtualization.

You can find the List here on the Microsoft Support Site: KB2974503 Recommended hotfixes, updates, and known solutions for Windows Server 2012 and Windows Server 2012 R2 Hyper-V Network Virtualization (HNV) environments



E2EVC Copenhagen

Speaking at E2EVC 2015 Berlin

Last year I was speaking at the Experts 2 Experts Virtualization Conference (E2EVC) at E2EVC Barcelona and E2EVC Brussels. And I am proud to announce that I will speak at E2EVC 2015 in Berlin next week from 12-14 June. Together with Michael Ruefli (Microsoft MVP for Cloud and Datacenter Management) I will speak about the latest announcement from the Microsoft Cloud and Datacenter evolution, covering topics like Azure Stack, Nano Server, Windows Server 2016, System Center 2016, Hyper-V and Microsoft Azure.

E2EVC Virtualization Conference is a non-commercial, virtualization community event. The main goal of the E2EVC is to bring the best virtualization experts together to exchange knowledge and to establish new connections. E2EVC is a weekend crammed with presentations, Master Classes and discussions delivered by both virtualization vendors product teams and independent experts. I am happy to be part of the community and listen to other industry leading experts, hopefully see you in Berlin.

 

 



CDN Consistent Device Naming

Cisco UCS supports Consistent Device Naming (CDN)

Yesterday I posted about Cisco UCS supporting RDMA (SMB Direct) with firmware version 2.2(4b)B. Walter Dey, former Cisco Distinguished Engineer at Cisco informed me not only about the RDMA feature he also showed me that Cisco UCS now supports Consistent Device Naming which was introduced with Windows Server 2012. Consistent Device Naming (CDN) allows Ethernet interfaces to be named in a consistent manner. This makes Ethernet interface names more persistent when adapter or other configuration changes are made. To use CDN in Cisco UCS you need to run firmware version 2.2(4b)B. This will help to make it a lot easier to identify network interfaces used with Windows Server 2012 R2 and Hyper-V.

Cisco UCS supports RoCE for Microsoft SMB Direct

As you may know we use SMB as the storage protocol for several Hyper-V deployments using Scale-Out File Server and Storage Spaces which adds a lot value to your Hyper-V deployments. To boost performance Microsoft is using RDMA or SMB Direct to accelerate Storage network performance.

RDMA over Converged Ethernet (RoCE) allows direct memory access over an Ethernet network. RoCE is a link layer protocol, and hence, it allows communication between any two hosts in the same Ethernet broadcast domain. RoCE delivers superior performance compared to traditional network socket implementations because of lower latency, lower CPU utilization and higher utilization of network bandwidth. Windows Server 2012 and later versions use RDMA for accelerating and improving the performance of SMB file sharing traffic and Live Migration. If you need to know more about RDMA or SMB Direct checkout my blog post: Hyper-V over SMB: SMB Direct

With Cisco UCS Manager Release 2.2(4), Cisco finally supports RoCE for SMB Direct. It sends additional configuration information to the adapter while creating or modifying an Ethernet adapter policy.

Guidelines and Limitations for SMB Direct with RoCE

  • SMB Direct with RoCE is supported only on Windows Server 2012 R2.
  • SMB Direct with RoCE is supported only with Cisco UCS VIC 1340 and 1380 adapters.
  • Cisco UCS Manager does not support more than 4 RoCE-enabled vNICs per adapter.
  • Cisco UCS Manager does not support RoCE with NVGRE, VXLAN, NetFlow, VMQ, or usNIC.
  • You can not use Windows Server NIC Teaming together with RMDA enabled adapters in Windows Server 2012 and Windows Server 2012 R2 or you will lose RDMA feature on these adapters.
  • Maximum number of queue pairs per adapter is 8192.
  • Maximum number of memory regions per adapter is 524288.
  • If you do not disable RoCE before downgrading Cisco UCS Manager from Release 2.2(4), downgrade will fail.

Cisco UCS C200 M2 with Windows Server 2008 R2 and Windows Server 8 #HyperV

Cisco UCS and Hyper-V Enable Stateless Offloads with NVGRE

As I already mentioned I did several Hyper-V and Microsoft Windows Server projects with Cisco UCS. With Cisco UCS you can now configure stateless offloads for NVGRE traffic which is needed for Hyper-V Network Virtualization.

Cisco UCS Manager supports stateless offloads with NVGRE only with Cisco UCS VIC 1340 and/or Cisco UCS VIC 1380 adapters that are installed on servers running Windows Server 2012 R2 operating systems.

To use this you have to create Ethernet Adapter Policy, and set the Configuring an Ethernet Adapter Policy to Enable Stateless Offloads with NVGREin the Resources area:

  • Transmit Queues = 1
  • Receive Queues = n (up to 8)
  • Completion Queues = # of Transmit Queues + # of Receive Queues
  • Interrupts = # Completion Queues + 2

And in the Option area set the following settings:

  • Network Virtualization using Generic Routing Encapsulation = Enabled
  • Interrupt Mode = Msi-X

Make also sure you have installed eNIC driver Version 3.0.0.8 or later.
