Buffer credits on the new Cisco MDS 9148S

This is from "Cisco MDS 9148 Multilayer Fabric Switch Q&A"

Q. Can the Cisco MDS 9148 Fibre Channel ports support extended distance and is an optional license required?

A. The Cisco MDS 9148 supports as standard extended-distance Fibre Channel ports with 8-Gbps Enhanced SFP (SFP+) long-wave optical transceivers (older 4-Gbps long-wave SFP optical transceivers are not supported). The architecture provides as standard up to 128 buffer credits for each group of four ports. The default is 32 buffer credits per port. However, this value can be changed in single-buffer-credit increments to a maximum of 125 buffer credits for a single port (the other three ports in the four-port group will have 1 remaining buffer credit assigned). No additional license is required.

Thank, I found that one myself, but this is about the regular 9148, not the 9148S <-- mark the extra "S". The model S is the new 16Gb model and I'm expecting to see the B2B credits doubled, just like what happened with the transition from 4 to 8Gb. But so far I can't find any evidence of the actual B2B credits per port group in that new switch.

We are still a little out from GA so we wont know until we get some more support material through and we get our hands on one, but my educated guess at this very early stage is it runs the same 16GB FC ASIC engine as the 9250i, which supports up to 256BB per 4 port group, with a maximum of 253BB per port.

I will post more when I can.      

Thanks. I didn't know it wasn't GA yet. I saw this switch @EMC World and thought these details would already be known. On the cisco website I didn't find the info either.

256 buffers available as a shared pool to each port group: 64 buffers per FC port

Its good to know my assumption was correct

GA very soon...

thank you. now where did you dig that up? Or has this switch just become GA?
