Emulex & ESXi6 drivers

Looks like ESXi6 support is showing up already for certain Emulex controllers. Talk about being over achievers!

Diskeeper 12 & Space reclamation

After running with all of the features enabled on a VM for a week I noticed that Forefront started to pickup random viruses being written to the root of the C-drive. Every time the filename was BzEngineTempFile followed by some number and a .dk file extension. After some digging the Space Reclamation feature within Diskeeper is actually writing temporary files with all 0’s to the root of the volume where Space Reclamation is occurring. However antivirus products (Forefront & McAfee have been confirmed so far) trigger a random virus as the source.

Forefront Protection Security Management Console (FPSMC) Hotfix 1 adds Internet Explorer 9 support

Well it looks like Microsoft is finally supporting IE9 for use with FPSMC under Hotfix 1 (released 6/5/2012). Outside of the aforementioned IE9 support, there a few other bug fixes with this update but otherwise it is pretty quiet.

The new update can be downloaded at:

This update will remove the existing installation prior to installation and can install over the top of the existing SQL database, no reboot is required.

Diskeeper 2012 First Look

Diskeeper 12 (aka 2012) has been released to existing customers under active support contracts.
  
Upon first launch you’ll be greeted with a new splash screen which makes you wonder if this is really the “re-branding” version.
      

      
After the initial splash screen the normal What’s New dialog is present.
  

      
As you can tell things are starting to look a bit different. The home screen has been completely redesigned.
  

      
In general what is being present in the volume summary is similar to what it was before but it a simplified view. What you’ll also notice is the option to “Reclaim Space”, this will zero out any used blocked on the volume. Which in a virtual environment can be a really BIG DEAL!!! That being said you must being running thin provisioned VMDK’s on thin provisioned LUNs. This part is pretty straight forward the last piece to make your life is the availability of the SCSI UNMAP command being supported by your storage vendor otherwise you need to perform manual storage vmotion’s to LUNs of different block sizes to reclaim any inflated space.
  
In the time I’ve used it since install system resource usage has been about what is was with previous releases and so far has shown no performance issues as of yet. I’ll post a followup to this post after I have some time to test out the reclaim space functionality a bit more.

WSUS Syncronization logging

When working with a WSUS console if you ever need to look at the Syncronizations it takes a long time to load. This is due to the way the logging functionality was designed which over months or years can cause this pain to minutes to load in some environment. However, this data can be cleaned to provide much faster load times.

If you want to purge the entire Syncronization history:

DELETE FROM tbEventInstance WHERE EventNamespaceID = '2' AND EVENTID IN ('381', '382', '384', '386', '387', '389');

Otherwise if you want to keep the more recent records you could do something like the following:

DELETE FROM tbEventInstance WHERE EventNamespaceID = '2' AND EVENTID IN ('381', '382', '384', '386', '387', '389') AND DATEDIFF(month, TimeAtServer, CURRENT_TIMESTAMP) >= 2;
