Got this card to play with, haven't installed it yet. I'll install it in my storage ESXi server so SR-IOV/NPAR will definitely help a lot. All the offloading features will help NSX-T as well. I don't have 20gb switch so it has to run at 10gb speed for now.
Based on FastLinQ 41000 chipset, I think it's same as Qlogic QL41212. I have CX-3 but SR-IOV is not supported anymore, I have one CX-4 too and will see which one works better.
Interesting feature
I/O Virtualization and Multitenancy
• SR-IOV (up to 192 virtual functions)
• Switch-independent NPAR, NPAReP
• GRE and NVGRE packet task offloads
• VXLAN packet task offloads
• GENEVE packet task offloads
RDMA Universal RDMA
• RoCE
• RoCEv2
• iWARP
• Storage over RDMA: iSER, SMB Direct, S2D, and NVMe-oF
• NFSoRDMA
• iSCSI extensions for RDMA (iSER)
• Low latency
RDMA Use Cases
• S2D
• PVRDMA
• Live Migration
• SMB Direct
• NVMe-oF
• NFS
• CEPHS over RDMA
