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.

Distinguished Judges for the UCS Power Scripting Contest

Cisco UCS PowerShell Scripting Contest

In the Microsoft world PowerShell is the tool to automate everything especially in your datacenter. I already mentioned that Cisco offers some great enhancements for the Microsoft Datacenter stack. If you are using a Cisco UCS solution you can integrate System Center Virtual Machine Manager, Orchestrator and others. But Cisco does also offer a PowerShell module for the UCS called Cisco UCS PowerTool. The UCS PowerTool allows you to automate management and deployment tasks very easily via Windows PowerShell. By the way, one of the coolest features in the Cisco UCS PowerTool is the ConvertTo-UCScmdlet.

Cisco announced the UCS Power Scripting Contest

Everyone is invited to share their scripts and possibly win some prizes by entering the UCS Power Scripting Contest on the Cisco Communities.  The contest will run until May 11th.  A distinguished panel of judges (Jeffery Snover, Rob Willis, Don Jones, Hal Rottenberg and Thomas Maurer) along with other members of the community will select the grand prize winner from a set of five finalists.

Distinguished Judges for the UCS Power Scripting Contest

I am proud to be one of the Distinguished Judges for the UCS Power Scripting Contest and I hope we will see some great solutions. To get more information about the contest check out the Cisco Blog from Bill Shields and the UCS Power Scripting Contest website.



UCS Mythbusters

In this clip from episode 100,Jimmy Ray and guest Jeff Silberman address the myths being portrayed by Cisco’s competitors, and demonstrates why it just doesn’t hold water. A must-see segment for you competitive types!



How Microsoft Hyper-V and the Cisco UCS changed our lives

Cisco UCS Hardware

At the end of last year we had our Cisco UCS ordered and in your datacenter. In January we started the testing and made the Clusters ready for the production environment. In February we started the migration of our existing environment, mostly P2V and also some V2V migrations.

Here some interessting facts about our Cisco UCS and Hyper-V project.

  • We use 12 Cisco UCS Blades this is like 10 HE of rackspace
  • We migrated 45 Windows Servers and 47 Unix Servers in just one week
  • We replace 2 racks of server with a half rack of two Cisco UCS Bladecenters
  • We think we can replace 2-3 racks more with our two Bladecenters.
  • At the end of this year we think we could replace 4-5 racks with 1/2 rack
  • We still have a lot of physical and virtual server which will be needed to be migrated to the Bladecenter.
  • We will get even more out of our Blade Servers by activting Hyper-V Dynamic Memory as a new feature of Hyper-V R2 ServicePack 1

This migration had a lot of positive influence on other things in the datacenter.

Datacenter Power

  • we need now 4% less energie overall
  • we need now 6% less cooling overall
  • we need less space (1 and 1/2 racks at the moment)
  • now our system administrator travel 50% less to the datacenter, because of hardware defects or other administrative tasks.
  • We can deploy new servers in minutes instead of hours

I think all of this numbers (except the time we need to deploy new servers )will increase after the next migrations.

Now I started to write a series of blog posts about installing Microsoft Hyper-V R2 on the Cisco UCS system:

Microsoft Hyper-V and the Cisco UCS Bladecenter are a powerful team. The UCS Virtual Hardware takes alot of complexety from the hypervisor in your case Hyper-V. You don’t need NIC teaming and stuff like that. Thats is making it very easy to deploy Hyper-V Clusters. And with the Microsoft System Center Virtual Machine Manager you can save a lot of time in managing your clusters, hosts, virtual machine and also in P2V and V2V migrations. Since Microsoft SCVMM supports Windows Powershell you can also do a lot of scripting automation. And with the release of the new Version of SCVMM (System Center Virtual Machine Manager 2012) this will even get better for deploying new virtual machines, services and even public and private clouds.

Hyper-V R2 SP1

We started with Microsoft Hyper-V R2 Servers before the release of Service Pack 1. We think we can even get a lot more out of your systems with the new Dynamic Memory feature for Hyper-V which comes in Service Pack 1.

At the end we think choosing the Cisco UCS, Microsoft Hyper-V and Microsoft System Center Virtual Machine Manager for our datacenter was the best choice we have made, in terms of costs and technology.
