Physical System Notes

• BIOS settings used:
• Workload Profile: Virtualization - Max Performance
• Thermal Configuration : Maximum Cooling

Storage Notes

• 6 x 1.6TB internal SAS drives were connected to the P408i-a and P408i-p SR Controllers
• Create 1 x RAID 5 array containing 3 x SSD drives, on P408i-a.
• Create 1 x RAID 5 array containing 3 x SSD drives, P408i-p.
• Create 17 x logical disks on first RAID array and 16 x logical disks on the second RAID array.
• First logical disk was used for OS and remaining logical disks were partitioned for the VMs of 1 tile.

Client Driver Notes

• All prime clients were VMs running Red Hat Enterprise Linux Server 7.1 KVM
• The prime controller ran on the first vClient.
• One vClient per tile ran all the workloads
• Each vClient has 6 vCPUs, 12GB memory, 16GB disk, 1 virtio_blk device and 1 i40evf device
• The first vClient acted as prime controller therefore had one more virtio_net device for management
• All physical clients have 2 x 10 Gbps ports, which were configured to have 16 VFs each. Each vClient used one VF.
• The client VM images were provided by the system local disk
• Three physical clients each hosted 10 vClients, and one physical client hosted 2 vClients for a total of 32 vClients.

Other Notes

• 1 x HP H3C S5820-24XG-SFP+ switch was used to connect the clients and the SUT
