Has anyone had experience with mounting a FAS2750 in an older HP Systems server rack. The rack has round hole / Clip nut design, and the universal mounting kit has supplied adapters that would fit the holes, but there is a side "support" with additional mounting holes that doesn't allow the rails to align with the hole adapters. Something like an HP server rail kit will clear this, but with the heavy duty build on the Netapp rails the clearance doesn't quite happen.
