Multiple IB Fabrics on a Single BX5020?

Infrastructure & Networking Switches and Gateways Gateways
1

Is it possible to use a single BX5020 gateway to connect multiple IB fabrics to multiple Ethernet networks?

For instance, could I have one IB fabric connected to port A1, bridged to an Ethernet network via a LAG on ports A2 and A3, and a different IB fabric connected to port B1, bridged to a different Ethernet network via a LAG on ports B2 and B3?

Bonus question: If it is possible to do this, how does having multiple bridges affect the limit on the number of vNICs? Is the 1k/4k limit global across the BX5020, or per bridge group?

Thanks in advance for any answers or suggestions,

Hi Rusty,

Answer is yes for the first question.

Second question: it’s a per Bridge Group Limitation ( A,B,C,D), but please note that the BX5020 supports/tested up to 5k vnics in total, mentioned in the FIT-BXM relesae notes
