I have BL460c Gen8 with 554FLB each with 4 FlexNics. I configured the two management nics to auto and configured the other two for 10Gbps which gives it a minimum 5.5Gbps to 10Gbps.
My issue is I cannot get 10Gbps speeds between two hosts in the same enclosure. I am using iPerf but it appears I can only get a maximum of ~5.3Gbps on a 10Gbps link. What exactly and I missing here? I have also enabled SR-IOV on the hosts (Hyper-V) and those can only get a maximum of ~4Gbps becacuse the guest only sees the minimum speed (which is 5.5Gbps).
Shouldn't I be able to achieve closer to 10Gbps? These servers have plenty of CPU and memory and since iPerf runs in memory the disk shouldn't be causing a problem.
Ignore the right blade enclosure:
Please check configration speed set on the server profiles , do any other server with same nic getting 10gb speed, update the firmwares of nic to latest and see.
