Recently I have been doing some "sanity checks" to make sure my systems are properly "tuned" for maximum performance.
One area that I wanted to double check was Partition alignment both in Windows OS and VMware LUNs.
I came across a blog that was full of good information that I thought I would share with the group.

If you use Windows Server 2003 or older your partitions are not automatically aligned.
If you use Windows Vista or older your partitions are not automatically aligned.
If you use VMware and you created your LUNs before a certain version you might want to check the alignment or use the GUI to create replacement LUNs and move your VM to the newly created LUN.
Alignment also applies to UNIX and Linux.
I hope you find this information useful.
