question about Priority Flow Control and RDMA

question about Priority Flow Control and RDMA

[Andrea Gozzelino]

Hi all,

I use RDMA verbs (iWARP on IntelNetEffect adapters, RoCE on Mellanox
cards, ...), but I would like to insert the Priority Flow Control (PFC).
Mellanox cards support it, but I have not idea about switch. I study
both the configuration back to back and the configuration with switch.
The actual experimental setup has an Extreme Summit X650-24x switch,
without optional parts. In next future, probably I will use Juniper
JUNIP 4500 switch.

Could you please suggest me switch and adapters to obtain a corret use
of PFC feature?

Thank you.
Best regards,

Andrea Gozzelino

Cisco Nexus switches support PFC and other DCB standards.
