BL660-Gen8 FLB port assignment questions

A port mapping question from Bob:

 

************

 

Can someone confirm the behavior of a BL660 Gen8 with a single FLB.

If a blade is in slot 3, should the NIC ports show for port 3 or 11 ?

 

My customer was expecting the 1st FLB to show as port 3. I figure both 3 & 11 would be valid for a full slot blade.

 

Please confirm “normal” or expected behavior.

Info from Norman:

For your reference. A single image depicting the port mapping assignments for various blade formats.

 

Note that the term LOM should be replaced/substituted for FLB for ProLiant Gen8 or later.

 

Note that I/O Capacity will have changed with the introduction of the 20GB Ethernet capability.

Yes, this is as designed.  Here is a screenshot of a BL660 I have in the lab:

Notice the blade is in Device Bay 1 and the FLB is only using port 9 (covered bottom bay port).

 

Here is another BL660 with 2x FLBs installed:

This one has FLB2 mapped to port 1.  Hope this helps.
