Configuring RDMA and RoCE on Netgear M4300-24X24F stack
Good morning all, I am working on a hyperconverged Hyper-V 2016 environment with Storage SPaces Direct (S2D) on 2 hosts, which requires Remote Direct Memory Acces (RDMA) over Converged Ethernet (...
So the short answer is: No it is not possible to use RoCE with M4300?
Let me take that back: I think you can use M4300 for RoCE.
Please keep me honnest here, but first I believe RoCE can work either in Lossless Ethernet environments (so, in a network with Global Flow Control enabled, or Priority Flow Control - PFC - implemented), or Lossy Ethernet environments (so, without any Flow control).
In Lossy Ethernet environment, RoCE can be configured in Resilient RoCEv2 mode on server/storage side.
M4300 can certainly be configured for RoCE Lossless Ethernet mode instead, either using standard 802.3x Flow Control, or better, the only feature inherited from M6100, namely Priority Flow Control in order to be able to differentiate between different flows.
PFC is available in M4300 CLI . You can download the CLI manual here http://www.netgear.com/support/product/M4300-24X24F#docs
PFC configuration commands and examples can be found starting page 980. Pleae kindly let us know how it goes. Please follow the configuration flow starting page 980.
Regards,
I had already found the PFC indeed, and in the edployument guide they also talk about priority 3.
I have now configured the ports which have the servers connected and the stacking ports for PFC.
Now to configure the WIndows servers and see :)
