Storage Notes

• The System Under Test has 4 3.2TB NVMe SSDs configured as one RAID5 arrays in BIOS by Intel(R) Virtual RAID on CPU.
• The System Under Test has one NVMe SSD contains the logical volume for the hypervisor OS that was booted.
• The RAID disk is formated by xfs and mounted to a directory. The disks for the VMs were in that directory.

• All VMs were assigned a VF that is routed to the NUMA node to which the VM's VCPUs were pinned.
• After the system booted, 1GB huge pages were manually allocated on the NUMA nodes. 961 1GB huge pages were allocated on each NUMA node.

• Three client systems each host ten prime client VMs, One client system host twenty prime client VMs. One client system hosts the prime controller VM.
• Each prime client VM has 10 VCPUs, 16 GB memory, and a 12 GB disk. 1 ixgbevf and 1 virtio_blk device were used in all client VMs.
• All prime client VMs run Red Hat Enterprise Linux 8.0.The first prime client acted as prime controller therefore had one more ixgbevf device for management

Other Notes

• An external 10Gb Ruijie RG-S6220-48XS3QXS switch was used to connect the client systems to the system under test (SUT).
• The SUT used the four dual-port 10Gb PCIe NICs for communication with the VMs.
• The SUT NICs and the external client systems were connected to the switch using 10Gb SFP+ DAC cables.
