The reliability needs improvement. We have had some issues.

The issue is that Dell's no longer selling this product in the near future. It's almost the end of life.

Overall, it offers a lot of good features for the industry. I don't recall any that are lacking per se.

We had a few minor issues with compatibility on the latest version during the installation process.

I can't think of anything that needs to be improved at the moment. A lot of evolution is occurring with Blade PowerEdge, including, what call, the blade servers. The VxRail should be opened to allow other virtualization platforms to be used. 

There could be some more ports added in the future.

A feature that needs to be added is the ability for full container storage.
