EX4600 RDMA over Converged Ethernet (RoCE) support?

Hi,

 

does anybody know if RDMA over Converged Ethernet (RoCE) is supported on EX4600?

 

Based on this:

https://www.juniper.net/documentation/en_US/junos/topics/concept/fibre-channel-cee-features-understa...

 

I would say yes, but since I can not find anything written specifically about RoCE & EX4600, I would like to know from knowledgable experts here?

 

Thank you in advance ...

Hi MM-Zel,

 

RoCE relies on DCBX which the EX4600 supports:

UPDATE:

 

Reply directly from Juniper ("Sr Partner SE" person) for reference:

 

"We have the number of switches supporting DCBX with ECN, but there’s no explicit support for RoCE yet.

DCBX is just one of prerequisites.

As I have mentioned, the first our platform with RoCE support will be QFX 5100. I would consider seriously QFX 5100 – it has above mentioned features and there is a chance for RoCE support yet in this year. I see RoCEv2 support for QFX5100 scheduled for 17.4."

 

So seems no explicit support for RoCE on EX4600 ...

Just FYI.  This enhanced supported is scheduled for 17.4 release, but will most likely only be supported (tested) with QFX5110, at least at that time frame.  For any new deployments, people should only consider QFX5110, and not QFX5100.  Whether EX4600 also receives this support is to be determined.

 

Again, just FYI.
