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.

It is a very scalable solution that allows you to add any product of ExaGrid to it.

Apart from the backup administrator, more than 1,000 users operate on the solution in our company. We need one administrator for the solution in our company.

My company may plan to increase the usage of the solution in the coming years.

The tool's scalability is very good, and no issues were encountered. One of the best aspects is combining newer and older models. These models support the latest software versions. However, support for older models can be expensive, so investing in new ones with updated support and potentially better discounts is often more cost-effective. My company has thousands of users for the ExaGrid EX Series. 

It's very scalable. 

Only I use this solution. It backs up all of our data, company-wide.

When speaking about a scale-out, you want to have better equipment. You cannot just add a disc to the current equipment. You have to buy another one and put it together, in parallel. If you think of this as scalability, it could be a little more expensive. However, it also adds more CPU power and that can be an advantage. Regarding the cost of adding a second box, ExaGrid says that they have pretty good discounts, they try to compensate for it.
