I am about to build out our first SAN, and am getting ready to order equipment, and was curious, what are Dell's plans for 10GB?  I see that the 6224 has 10GB available, but when does it plan on adding it to the 5000 series switches?  I won't be using the L3 features for our storage.  I am needing it for uplinks, not for individual hosts (yet!)

Also, many other vendors have moved to transcievers that do send/recieve on different wavelengths on the same strand of fiber, (no pair, just a single fiber!).  Does Dell have any plans to support these in the future? 

I really don't want to have to use up multiple pairs of fibers as a trunked uplink between our switches, especially since I'm running out of dark fibers between my buildings. So I either need 10GB, or single fiber uplinks..
