Having SMB, NFS, and S3 support helps my team day-to-day as we mostly use NFS or SMB, but we also want to use S3, especially for reading files and reading objects.

The customer support from Dell is bad, really bad. We needed support because Dell offers support sold as an add-on product, Superna, and it has been a nightmare.

Dell PowerScale (Isilon) certainly has room for improvement; since it does not provide SAN at the moment, I would look for Dell to create a complete unified solution just like NetApp.

An improvement of that technology when it comes to DR implementations is something that I would look to see in the future. It is there, but it is not 100% in a way that is easy to implement.
