Hi folks! So everyone and their dog is virtualizing right now. The question is, how do you know you are planning for the right capacity? How do you know if you are over or under provisioned? You can make a ball park guess and just eyeball it, but that isn't really a technically sound way of...

Hi folks! Now with virtualization you find a lot of people putting their apps in the cloud.

Hi folks! One of the common questions you might find in the virtual world with VMware is how much free space do I leave on a LUN? When is it not enough? A common mistake is to think you only need enough free space for the size of the VM itself and not much more. Well if you do that you'll...
