New and free alignment tool: UBERAlign

Incorrect alignment of the VMware virtual disk on the storage array layer can result in performance issues. Basically it means the storage array needs to read two blocks of data instead of one when disk is properly aligned. This has a negative effect on the disk performance and thus application. Lots of information can be found on the internet. A good article which explains alignment written by Duncan Epping can be found here.

Alignment is done correctly by Windows Server 2008 and Windows 7 but other guest operating systems might need a manual re-alignment.

This freshly developed, new and free tool will check if alignment if correct, perform correction on the alignment and even reclaim diskspace.

Take some time to read the various posting, it can help save some disk problems.
