Storage/NAS Evals

We are looking for a strong NAS system, I'm leaning towards a clustered scale up/out system versus buying a box that I have to replace every 4 years. I think Isilon is the proven leader in this space, and we've selected them to go up against the king (Netapp). Here are the criteria we used to get it down to these two. We are looking into them in depth now.

Have you considered BlueArc? Many (if not all) of the features you're describing here are easily met with BlueArc. Plus, you're looking for scale and performance, which BlueArc excels at quite nicely. http://www.bluearc.com
