Client Driver Notes

• Each prime client VM has 8 VCPUs, 16 GB memory, and a 12 GB disk. 1 vfio_pci and 1 virtio_blk device were used in all client VMs.
• All prime client VMs run Red Hat Enterprise Linux 8.0.

Other Notes

• An external 100Gb H3C S6850-56HF switch was used to connect the client systems to the system under test (SUT).
• The SUT used the four dual-port 100Gb PCIe NICs for communication with the VMs.
• The SUT NICs were connected to the switch using 100Gb QSFP28 DAC cables, the external client systems were connected to the switch using 25Gb SFP28 DAC cables.
