[gpfsug-discuss] Spectrum Scale, InfiniBand and QoS

[Thomas Bernecker]

Dear all,

we recently found this presentation from 2021: https://www.spectrumscaleug.org/wp-content/uploads/2021/05/SSSD21DE-06-Improving-Spectrum-Scale-performance-using-RDMA.pdf On page 10 it explains by setting the RDMA device in a specific way one could employ QoS with InfiniBand, which is something we would like to achieve as well. Has anyone a working environment using QoS with InfiniBand outside of the ESS domain? If so, would you share your experience? Sorry for asking a rather broad question, but it seems that this is not well-known stuff ...
