We are deploying them extensively, having selected them from all the usual Trident-based suspects.  There are hooks coming to tune the buffers away from FCOE, which is important to us as we are using them only as L2 Ethernet switches. 

Given the lack of buffer, we found that they can do about 7 Gb/sec on 10G ports with an 80 Gb/sec LAG (or 2x40) uplink without queue drops in a microburst-heavy environment such as ours.
