ExaGrid EX Series is scalable. You can connect another ExaGrid Appliance to it to provide more disk space. I have been told it is simple to upgrade, you do not need to dispose of the current hardware, you can add to it. There is de-duplication and other features that use space but we have not needed to add disk space and we are only at one quarter used so far. We had the Barracuda Backup Appliance previously called Barracuda Backup, and it was not flexible, we were running out of space. Some companies do proper specification and then others try to bring their price point down by getting you in. Then in a year or two down the road, you start running out of space, which is what happened to us with the Barracuda solution.
