Client Driver Notes

• The client systems VMs using Red Hat Enterprise Linux 6.5.
• Two virtual clients were used for each tile,One virtual client per tile ran the webserver workload and the other virtual client per tile ran the other workloads.
• The first virtual client is the prime controller.
• Each prime client VM has 10240 MB memory, and a 20 GB disk,1 ixgbevf device and 1 virtio_blk device are used.
• Each prime client has 4 VCPUs.
• Each webserver client VM has 10240 MB memory, and a 20 GB disk,1 ixgbevf device and 1 virtio_blk device are used.
• Each web client has 4 VCPUs.

Other Notes

• A H3C S6812 24-port switch was used to connect client systems to SUT.
• The 10GbE ports were attached to a dual port 10 GbE SFP+ expansion module.
