WebApr 7, 2024 · Both VLAN tag and PKEY are 16 bit field 2. The VLAN tag carries the priority while the PKEY field doesn't. The priority in InfiniBand is carried in the SL (Service Level) field (four bits - compare the 3 bit priority within the VLAN field) within the InfiniBand LRH (Local Route Header) header. 3. WebInfiniband is a protocol (similar to Ethernet) and could be carried over any of the above physical mediums. For example, 40Gbps Infiniband typically uses QSFP+. tallguyyo • 2 yr. ago so would a DAC for SFP+ 10gbps card work for a QSFP+ card, seeing they are same physical connector. zrgardne • 2 yr. ago Qsfp is 38 pins SFP+ is 20 WebApr 1, 2015 · Ethernet has RDMA over Converged Ethernet, or RoCE, which may not be quite as fast as 56 Gb/sec or 100 Gb/sec InfiniBand, but even at 40 Gb/sec, it is good enough for a lot of customers. You might think that InfiniBand would dominate the networking space because of its low latency advantages. teacherhub nyc sign in
