UCS 5108 con C3260

Buenos días,

Tengo un chasis blade (PN: UCSB-5108-AC2=) con dos Fabric Interconnect UCS-FI-M-6324 internos configurados en cluster. De otro lado tengo un c3260 (UCSC-C3260) con un SIOC (UCSC-C3K-M4IO) con dos puertos 40G habilitados. Quiero que este storage server funcione como una suerte de SAN hacia los blades del chasis 5108, he intentado varias formas de configuración de los puertos del FI 6324 (Por cierto estoy utilizando el cable QSFP-4SFP10G-CU3M= el cual me permite tener de un lado un conector QSFP (en el SIOC) y del otro lado 4x10 SFP 10G, de los cuales estoy conectando sólo dos puertos (3 y 4) en ambos FI 6324 del cluster). Logro conexión hacia la LAN ya que el puerto 01 del FI6324, que físicamente va hacia mi switch LAN, está configurado como "Uplink port", pero mi problema es como haría para "ver" el c3260 o que configuración de puerto deben tener los puertos del FI6364 para que haya conexión?

Adjunto un pequeño diagrama para que se entienda mejor.

Hi Joe.

If I'm reading your diagram right, you need to get 40Gb QSFP cables, and connect your SIOC up to your 6332 FI (40Gb QSFP to 40Gb QSFP)

I'll need to check the SIOCs based vics, but I know the 1387 40Gb MLOMs will not correctly connect 6300 series FIs via 10Gb end links (i.e. breakout cable, or CSV 40Gb to 10Gb).  You could connect the 40Gb breakout if going to a 6200 series I believe.

Other considerations for the Cisco VIC 1387 card:
  — VIC 1387 natively supports 6300 series FI.
  — VIC 1387 also supports Cisco QSA Modules when working with HX-FI-6248UP or
     HX-FI-6296UP is desired.
  — Breakout cables cannot be used to connect to 6200 series fabric interconnects. Use
     a QSA instead. Use of 10GbE is not permitted with 6300 series FI.

 

If the 3260 was in standalone mode, you could probably connect it to upstream switch with breakout cables.

You might be able to connect 3260 with breakout cables, if the FI interfaces are in appliance mode (non-ucsm integration for 3260)

 

Kirk...

 

I understand that it is a design flaw.
But the c3260, through the SIOC2, is seeing the existing connections in its two ports and detects that in "operating speed" there is a 4x10Gbps connection, this is fine ?.

I show you what the SIOC2 is seeing:
