MVP for another year

davebermLeave a comment

I am very happy to announce that I have been elected Microsoft Most Valuable Professional (MVP) in Clustering for a second year in a row. It is a great honor and I certainly enjoy the benefits of being recognized as an MVP, including free dinners and drinks wherever I go! Well, OK, that is just my imagination getting the better of me but I did enjoy the MVP Summit and meeting lots of really smart people. In addition to being elected MVP I had the best day ever on my blog, until I discovered that WordPress played an April fool’s day joke on me! I thought that my being elected MVP must have been the headline on CNN or something. They really got me good!

 

MVP for another year

You might want to hold off on the SP1 upgrade for your cluster

davebermLeave a comment

There are some reports on the newsgroups of storage validation failures after upgrading 3+ node clusters to Windows Server 2008 R2 SP1. It seems Microsoft is aware of the issue and they are investigating. I have been following this thread to keep up to date on the issue

http://social.technet.microsoft.com/Forums/en-US/winserverClustering/thread/e67026af-7f9b-4698-9ca7-11853431ed86

You might want to wait for some sort of resolution before you apply SP1 to your clusters.

Configuring the Microsoft iSCSI target software for use in a cluster

daveberm4 Comments

Now that Starwind has stopped offering a free, limited version of their iSCSI target software you might be looking for an alternative for your labs. Microsoft has recently made their iSCSI target software available as part of the Windows Storage Server 2008 R2 download on Tech-Net and MSDN. It is not for use in production and has some of its own licensing restrictions, but it works fine and it is free for Tech-Net and MSDN subscribers.

I recorded some really quick and dirty videos that aim to show you how to configure the iSCSI target and iSCSI initiator software in under 7 minutes. At the end, you will have a shared disk array ready to start your shared storage cluster. Hopefully when I get some more time I’ll actually write these steps out, but in a pinch this will give you the general idea of what needs to be done. There are plenty of other features, but for a lab environment this will do the trick.

The stats helper monkeys at WordPress.com mulled over how this blog did in 2010, and here’s a high level summary of its overall blog health:

Healthy blog!

A helper monkey made this abstract painting, inspired by your stats.

About 3 million people visit the Taj Mahal every year. This blog was viewed about 54,000 times in 2010. If it were the Taj Mahal, it would take about 7 days for that many people to see it.

In 2010, there were 13 new posts, growing the total archive of this blog to 30 posts. There was 1 picture uploaded, taking a total of 2kb.

The busiest day of the year was August 18th with 347 views. The most popular post that day was Step-by-Step: Configuring a 2-node multi-site cluster on Windows Server 2008 R2 – Part 3.

Where did they come from?

The top referring sites in 2010 were social.technet.microsoft.com, social.msdn.microsoft.com, google.com, google.co.in, and ditii.com.

Some visitors came searching, mostly for sql 2008 r2 cluster step by step, clustering for mere mortals, there was an error setting private property ‘requirekerberos’ to value ‘1’ for resource ‘sql network name, and hyper-v r2 sizing.

SQL Server Denali and HADRON

davebermLeave a comment

Microsoft’s latest version of SQL, code named Denali, is currently in CTP. One of the most anticipated feature is something called HADRON. Basically, it is has been described as mirroring 2.0. The best features of HADRON as I can see compared to mirroring as it is in 2005/2008 are as follows:

  • You can query the mirror (now known as a replica)
  • You can have more than one replica
  • Database are grouped into availability groups to ensure related databases always fail over together
  • Support for replicating more than 10 databases

If you want a great preview, check out fellow MVP Brent Ozar’s post, SQL Server Denali Rocks!

From reading Brent’s post I gather Microsoft only plans to include this in the Enterprise version of SQL. That is too bad for the many customers running SQL Server Standard as traditionally there is a significant price jump to go from Standard to Enterprise. However, that is good news for the 3rd party replication vendors out there who are providing similar functionality today on SQL 2005/2008 on Standard and Enterprise Editions.

While it is not an exact duplicate of HADRON, a multisite cluster using SteelEye DataKeeper Cluster Edition for SQL Server gives you a great solution for HA/DR without requiring shared storage. So while we wait for Denali and all the application vendors to start supporting Denali you might want to have a look at what SteelEye DataKeeper Cluster Edition can do for you today!

Important Security Update for Windows Server 2008 R2 Clusters

davebermLeave a comment

It seems as if there could be a vulnerability which would allow unauthorized access to administrative shares! You will certainly want this patch ASAP and also don’t forget to check the permission levels on your administrative shares after you apply this patch.

http://www.microsoft.com/technet/security/bulletin/MS10-086.mspx

Recommendation. Microsoft recommends that customers consider applying the security update using update management software, or by checking for updates using the Microsoft Update service. Additionally, after applying the update, customers should check the permissions on existing cluster disk administrative shares and set the proper access levels for their environment.

What does it cost your business when your SAP system is down due to a hardware failure, an administrator mistake or for maintenance activities?  The impact can range from thousands of dollars lost in sales per minute to significant drops in employee productivity and customer satisfaction.  Through the implementation of a high-availability cluster configuration, downtime from both planned and unplanned outages can be virtually eliminated.

SteelEye and SAP AG have worked closely together to ensure that the availability needs which corporate users have for critical business infrastructure running on Linux and Windows platforms are achieved through the deployment of monitoring and switchover solutions for SAP Application Server (AS) and both JAVA and ABAP Web Application Server (WAS) environments.

Please join Steel Eye EVP of Product Management, Bob Williamson as he explains how you can minimize your downtime using SAP High Availability with SteelEye.

Hyper-V Multi-Site Demo at Tech-Ed 2010 New Orleans

davebermLeave a comment

If you are at Tech-Ed in New Orleans this week make sure you stop by the Windows Server Failover Cluster booth in the Technology Learning Center and have a look at the multi-site Hyper-V cluster demo using SteelEye DataKeeper Cluster Edition as the replication engine. I’ll also be in the booth to answer any questions you may have. SteelEye also has a booth at the show if you would like to discuss becoming a partner or customer!
