Nexus 9372TX with B22HP FEX compatibility via QSFP+ breakout cables

[Radovan Djogo]

Hello,

I am interested if this configuration is supported:

- B22HP FEX module for c7000 blade chassis connected to 9372TX parent Nexus switch. 

  The only option I see is to connect the QSFP+ end of the breakout cable to one of 6 40G ports on Nexus 9372TX and one to four of SFP+      breakouts to B22HP uplink ports.

Based on these release notes, I don't think it's supported:

http://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus9000/sw/7-x/release/notes/70341_nxos_rn.html#_Toc430850301

even though 9372PX is (FETs can be used, no need for breakout, etc)

However, 9372PX can't support 100Mbps connections still present on iLO and similar mgmt intefraces.

Thanks.

Hi,

According to the link you posted, 9372TX supports the breakout cable.

The following switches support QSFP+ with the QSA (QSFP to SFP/SFP+ Adapter) (40G to 10G QSA):

¯    N9K-C93120TX

¯    N9K-C93128TX

¯    N9K-C9332PQ

¯    N9K-C9372PX

¯    N9K-C9372PX-E

¯    N9K-C9372TX

Also, most new servers support Gig iLO
