I've deployed large SAN's on both SuperMicro 825/826/846 and Dell R610/R710's and I've not found any issues so far. I always make a point of installing Intel chipset NIC's on the DELL's and disabling the Broadcom ones but other than that it's always been plain sailing - hardware-wise anyway.
I've always found that the real issue is formulating SOP's to match what the organisation is used to with legacy storage systems, educating the admins who will manage it going forward and doing the technical hand-over to folks who may not know or want to know a whole lot of *nix land. My 2p. YMMV. --- W. A.
