You could try for an Arista DCS 7050s. It does PFC, not sure if that‘s enough for you with DCBX and ETS if you‘re looking at RoCE or other RDMA projects.
That's a beast of a switch... interestingly they don't actually state in the spec that it supports the IEEE 802.1Qbb standard, yet it does do Priority Flow Control, does one assume that this implies the switch's PFC is not fully standard compliant?
I'm not sure if the VDX6740 support this ... but I might be able to get one for you.. although the shipping might kill the budget (from Dubai)
seems to support it:
The following draft versions of the Data Center Bridging (DCB) and
Fibre Channel over Ethernet (FCoE) standards
are also supported on
the VDX 6740:
•IEEE 802.1Qbb Priority-based Flow Control
•IEEE 802.1Qaz Enhanced Transmission Selection
•IEEE 802.1 DCB Capability Exchange Protocol (Proposed under theDCB
Task Group of IEEE 802.1 Working Group)
•FC-BB-5 FCoE (Rev 2.0)
As long as all the features on the VDX6740 are not locked away by licensing fees, I would indeed be quite keen, if you could PM an approximate total door to door when you have the chance that would be greatly appreciated. Thank you.
