We have 60 solution users in our organization.

As we employ the VMware for three hosts, we are not able to scale it too much. But, for our present needs it is scalable. 

The solution could be more scalable and I believe we could increase certain resources should the need arise. 

Scalability on rack-mount servers is not as good as with Blade servers.

It is a scalable solution. We have five customers using it.

I have read and I have seen the expansion modules of the Lenovo ThinkSystem DE Series, but I haven't yet used any of them because there's no need.

I have three or four customers that are using these systems, but I have no personal experience with the solution.

The scalability of the solution is good. It's very easy to add onto it.

ThinkSystem is scalable. Our clients are small top medium-large businesses and within that range, it works well.  

It is scalable.

We have about 20 clients that are using the Lenovo ThinkSystem solution.

It is scalable in our targets, but scalability is not important with these types of solutions.

The solution is scalable. Approximately 300 people are using it in our organization.

ThinkSystem has considerable scalability.
