Windows Server and System Center: Designed with You in Mind

If you’ve been keeping up with Microsoft related news, you’ve probably heard that Microsoft announced new features in Windows Azure, announced Windows Server 2012 R2, System Center 2012 R2, and SQL Server 2014. For many of these products, they are here less than a year after their predecessors. This is a huge accomplishment for Microsoft.

According to a blog post published by Brad Anderson, Corporate Vice President for Windows Server and System Center, Microsoft is able to do this because they are building for the cloud first.

By building for the cloud first, Microsoft says that they are able to do couple things:

Battle harden what is built. By deploying in Windows Azure first, Microsoft can ensure that they are delivering a solid product both in the cloud and on-premise.
Unify the planning and delivery across multiple products. With this wave of releases, Microsoft has brought together Windows 8.1, Windows Server 2012 R2, System Center 2012 R2, Windows Azure, and Windows Intune.

What this means for you as a Microsoft customer is that scenarios are being designed for better integration end-to-end, using real world feedback from people like you and I, and validated in the Windows Azure cloud.

It’s an exciting and interesting time for both Microsoft and its customers. I’m encouraged by the products I’m seeing and the scenarios that are being unlocked.

Windows Server 2012 R2 Preview Now Available

Tonight Microsoft has made available the public preview release of Windows Server 2012 R2. With this release, Microsoft is laying out its vision for what it calls the Cloud OS.

The Cloud OS is the platform that Microsoft is building with the release of Windows Server 2012 R2, System Center 2012 R2, SQL Server 2014 and Windows Azure. The four key tenets of the Cloud OS are:

Transform the Datacenter
Enable modern business applications
Empower people-centric IT
Unlock insights on any data

New to Windows Server 2012 R2 are such features as:

Storage Tiering within Storage Spaces
Software-defined networking
Virtual IP Address management
Windows Powershell 4.0
Windows Server Essentials Experience

Hands-On Labs at TechEd 2011 | How does it all work?

This week at TechEd 2011, an attendee favorite are the Hands-On Labs. I met with the good guys from XB Velocity to get a behind the scenes look at how everything works.

At the highest level, the labs are stored in an on-site private cloud and then accessed through Internet Explorer on each PC in the lab. Lets dive in and look at things at a deeper level.

What’s the hardware involved?

HP Bladesystem C7000 Enclosure with 16 blades
HP StorageWorks 4400 EVA with ~ 15TB of available storage
HP BladeSystem Onboard Administrator providing Enclosure Management, Flex Fabric Management, and HP Integrated Lights-Out (iLO)

What’s in each blade?

2 physical processors each with 6 cores (Intel Xeon X5670, 2.93 GHz, with Hyper-Threading)
128GB of RAM
2 146GB hard drives
1 320 GB HP IO Accelerator Card, powered by Fusion IO (provides 150,000 IOPS, Read speed 750MB/s | Write speed 550MB/s)
Windows Server 2008 R2 Datacenter SP1 w/ HyperV

How’s the infrastructure managed?

System Center Configuration Manager 2007 R2 – Used for reporting and deploying updates to lab clients
System Center Operations Manager 2007 R2 – Used to monitor all servers involved
System Center Service Manager 2010 – Used to run help desk and provide incident routing during the show
System Center Virtual Machine Manager 2012 Beta – Used for monitoring lab VMs and managing / monitoring infrastructure VMs

The Nitty Gritty:

The hands on labs this year are all running on a private cloud setup using the aforementioned hardware and software. This private cloud serves 350 users located in the lab area. All of the base lab VHDs (Virtual Hard Disks) are stored on the SAN, and differencing disks that point to these base VHDs are stored on each blade’s IO Accelerator card. When someone wants to start a lab, a copy of the virtual machine (already in a saved state for quick starts) is made, pointed to a differencing disk on the IO Accelerator, and the VM is then turned on and available to the end user. By doing it the this way, the labs are able to be run at optimal speed and there is little risk of any damage to the Base VHDs stored on the SAN. For better memory management within the VMs, Dynamic Memory is enabled to allow the VMs to take more RAM if they need it, and to give up RAM they don’t need.

End-User Experience:

When the user sits down in front of a lab station they are presented with a list of categories and labs to choose from. When they find the lab they click the Take Lab Now button and that begins the backend VM creation and startup process. Once the VMs have launched, another window opens on the second screen with the lab manual. If there are multiple VMs involved, there is tabbed navigation between each of the lab’s VMs. After the user finishes the labs, the VMs are shut down and then destroyed, or if a user leaves without ending their session, the system will automatically destroy the VMs after 40 minutes of inactivity. I’ve included some screenshots and photos of the setup below.
