Storage Notes

• The System Under Test has 16 400GB internal SSDs configured as two RAID5 arrays with eight disks each.
• Only one of the arrays is used and contains the logical volume for the hypervisor OS that is booted.
• The SUT is connected to the external IBM Storwize V7000 controllers using all eight ports of the four dual-port QLogic adapters.
• The 24 disks in each V7000 are configured into three 8-disk RAID5 arrays. Each array is allocated to its own storage pool.
• Each storage pool contains 16 logical volumes for VM images, enough for 96 tiles, though only 88 are used.
• Each of the VM logical volumes has 6 partitions, 1 for each of the 6 VM types in a tile.

• The IRQs for each virtual function PCI device are pinned to the CPUs on the socket to which the PCI device is routed.
• Each VM is given a virtual function that is routed to the NUMA node to which the VM's VCPUs are pinned.
• VM configurations are as follows:
• All VMs are managed with libvirt and created using the virsh utility.
• All VMs are created with the following XML template (exceptions noted below template):

• Seven client systems each host eleven prime client VMs. One client system hosts eleven prime client VMs and one VM for the prime controller.
• Each prime client VM has 4 VCPUs, 8 GB memory, and a 16 GB disk. 1 ixgbevf and 1 virtio_blk device are used in all client VMs.
• All prime client VMs run Red Hat Enterprise Linux 6.6.

Other Notes

• An external 10Gb Lenovo RackSwitch G8264 switch was used to connect the client systems to the system under test (SUT).
• The SUT used the eight dual-port 10Gb PCIe NICs for communication with the VMs.
• The SUT NICs and the external client systems are connected to the switch using 10Gb direct connect cables.
• An external 1Gb Lenovo RackSwitch G8052 switch was used to manage all the systems.
• All systems are connected to the 1Gb switch via a separate cable plugged into a 1Gb port on the system.
