Hi Cluster Fans, On Thursday, July 14 th we will be giving online training to user groups about Failover Clustering & Hyper-V: Planning your Highly-Available Virtualization Environment . This event is run in collaboration with Microsoft’s User Group Support Services (UGSS) and will be presented...

Hi Cluster Fans, One of the more frequent cluster network connection issues we see happens when the cluster cannot use WMI. WMI is Windows Management Instrumentation, which is an interface through which Windows components can provide information and notifications to each other, often between remote...

Hi, In this series of blog posts we will help you to design, develop and debug the Resource DLL you are developing to give your application high-availability with Windows Server 2008 & 2008 R2 Failover Clustering. We recommend you start with the other blog post in the series: ·...

Failover clusters ensure that workloads such as File Server, Exchange, SQL, and Virtual Machines are highly available. These resources are considered highly available if the nodes that host resources are up, however the cluster generally requires more than half the nodes to be running, which is known...

Since Failover Clustering traditionally requires shared storage (you could also use hardware or software replication between nodes), we get a lot of questions about which shared storage types we support. Windows Server Failover Clustering has a very flexible storage model that allows a wide variety of...

Hi Clustering and Scripting fans, If you’ve done any work with PowerShell v1.0 or v2.0, you have probably realized by now how rich the library of cmdlets is. There are a ton of cmdlets that allow you to automate almost any and everything across the system to use PowerShell. Here is one more thing...

Hi Cluster Fans, In this post we will discuss some of the implementation details around the Network Name (“NetName”) resource and its behavior in Windows Server 2008 R2. Introduction The purpose of Network Name is to allow clients to be able to resolve the DNS name to an IP Address to establish...

In Window Server 2008 Failover Clustering, the team invested significant time into making clustering easier. In the Windows Server 2008 R2 release we have continued down that path, adding several troubleshooting enhancements. One of the important aspects of troubleshooting a service outage is doing...

Hi Cluster Fans, Windows Server 2008 Service Pack 2 (SP2) is now available for download on the web! This blog post will walk you through performing a “rolling upgrade” from Windows Server 2008 RTM to Windows Server 2008 SP2. A rolling upgrade allows you to progressively upgrade your cluster nodes...

With Windows Server 2008 (and R2) Failover Clustering you can make almost anything highly-available. This does not only include programs and applications, but you can make any service running on the cluster highly available – even if it is custom or from a 3 rd party. These can be created, managed by...

Hi cluster fans, Our partners on the Exchange and Hyper-V team have recently published some great resources to improve your high-availability knowledge. Hyper-V: Free Training Microsoft is offering some free training for Hyper-V which includes modules on HA and Failover Clustering. ...

Hi Cluster Fans, Resources can be hard to find, so every few months we will be publishing an updated list of useful documents, guides and information to this blog ( http://blogs.msdn.com/clustering/ ). If there is any other useful Microsoft content which you feel is missing, let us know by...

Hi Cluster Fans, The Clustering & High-Availability team will be coming to TechEd, Los Angeles in May ( website ). We hope some of you can see our sessions and demo Failover Clustering in Windows Server 2008 R2 as a Hands-on-Lab. The cluster team will include Steven Ekren (Senior Program Manager...

Windows Server 2008 (and R2) Failover Clustering supports virtually every workload which comes with Windows Server, however there are many custom and 3 rd party applications which take advantage of our infrastructure to provide high-availability. Additionally there are some applications which were not...

Hi, A lot of people have asked about setting up NLB clusters on virtual machines. This is possible. But, there a few things to keep in mind. If you’re trying to create NLB clusters using Virtual Server Virtual Machines, before designing your solution familiarize yourself with the supported...

Hi cluster fans, If you ever browsed your cluster properties you may have noticed an entry for “PlumbAllCrossSubnetRoutes” and you’ve probably asked yourself, “what the heck is that?” The only thing on the web will point you to MSDN ( http://msdn.microsoft.com/en-us/library/aa371422(VS.85...

Hi Cluster Fans, The cluster team has been busy working on some great new features for Failover Clustering in Windows Server 2008 R2. Meanwhile our friends have written some great blog posts which you may find interesting. Thanks, Symon Perriman Program Manager Clustering & High Availability...

Next week the Clustering and High Availability team will be traveling to Barcelona, Spain for one of Europe’s largest IT conferences, TechEd EMEA ITPro, from November 3-7. Throughout this week we will be giving presentations, demos, chalk-talks, and instructor led labs, in addition to being available...

You may have noticed that in Windows Server 2008 that the "Share Subdirectories" option for file shares on a Failover Cluster has been removed...why would we do that? First off, let's take a stroll down memory lane and talk about the history of this feature and how it came to be... Let's timewarp...

Hi Cluster Fans, Failover Clustering in Windows Server 2008 no longer supports the traditional “rolling upgrade” which you may be familiar with from Windows Server 2003. This has given the impression that you will not be able to reuse your hardware. That is not true – with clustering’s built-in...

Don't let it happen! This goes beyond clusters. If an identity is deleted, nothing using that identity will be able to log on or authenticate against it. The service or application that you went through all the pains to make highly available on your cluster will no longer be available to clients....

Now that Failover Clustering deployments on Windows Server 2008 are growing, and our customers are spreading the word about how easy it is, we’re getting an increasing number of questions about “what’s new in 2008?” The short answer is – pretty much everything! We’ve enhanced virtually every component...

http://www.microsoft.com/windowsserver2008/en/us/clustering-home.aspx Hi Cluster Fans, For a long time we’ve been asked for a centralize location to find all of your clustering information – and it is here! This easy-to-use website offers information about our products, programs and resources...

Windows Server 2008 is launching on February 27th. This is an extremely exciting date for all of us here in Windows Server, especially in the High Availability team. Of course, for you, this means learning about all the cool new features in this release and planning your deployment; something you might...
