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.

I would like to see improvements in data deduplication. In our environment, the deduplication ratio is approximately 2 or 2.3 to 1, so I believe there can be enhancements in this area.

We have had a few performance issue calls, particularly from a group that does file transfers who noted that it is somewhat slow, but I do not think it is on the Isilon side.
