Physical System Notes

• Firmware settings used:
• Memory.PagePolicy=Adaptive
• OperatingModes.ChooseOperatingMode=Maximum Performance
• Power.PlatformControlledType=Maximum Performance
• Processors.C1EnhancedMode=Disable
• Processors.CPUPstateControl=None
• Processors.EnergyEfficientTurbo=Disable

• Processors.L1=Disable
• Processors.MONITORMWAIT=Enable
• Disable adapter option ROM on PCI slots with network adapters installed.

Storage Notes

• The System Under Test has 24 800GB internal SSDs configured as two RAID5 arrays with twelve disks each.
• One of the arrays contains the logical volume for the hypervisor OS that is booted.
• Each RAID disk has a large parition that is made into a volume group. The disks for the VMs are each allocated as a logical volume from one of the volume groups.

Virtualization Software Notes

• The following kernel boot options were used:
• audit=0 elevator=deadline hpet=disable clocksource=tsc tsc=reliable nohz=on highres=off cgroup_disable=cpu,cpuacct,memory,blkio,hugetlb intel_iommu=on iommu=pt pci=realloc nosoftlockup intel_idle.max_cstate=0 mce=ignore_ce nmi_watchdog=0 ipv6.disable=1 default_hugepagesz=1G hugepagesz=1G
• The following services were disabled after OS installation:
• irqbalance, postfix, smartd
• The following items were added in /usr/lib/sysctl.d/99-specvirt.conf:
• fs.aio-max-nr = 3145728
• kernel.perf_event_max_sample_rate = 1000
• kernel.sched_compat_yield = 1
• kernel.sched_min_granularity_ns = 10000000
• kernel.sched_wakeup_granularity_ns = 15000000
• kernel.sched_latency_ns = 20000000
• kernel.sched_migration_cost_ns = 150000
• kernel.numa_balancing = 0
• vm.dirty_background_ratio = 5
• vm.dirty_ratio = 10
• vm.swappiness = 0
• Configuration file /etc/modprobe.d/i40e.conf includes:
• blacklist i40evf
• options i40e max_vfs=0,0,64,64,64,64,64,64,64,64,64,64,64,64,64,64,64,64
• Network configuration is as follows:
• Ethernet devices eth2, eth3, eth4, eth5, eth6, eth7, eth8, eth9, eth10, eth11, eth12, eth13, eth14, and eth15 are the physical functions that are used by the host to provide physical transport for the virtual functions.
• Kernel module i40e does not have a max_vfs option and ignores it. Instead, a systemd initialization script reads the max_vfs option from /etc/modprobe.d/i40e.conf and allocates the virtual functions.
• 609 virtual functions were used for all the VMs.
• App, Db, Web, and Batch VMs are assigned a VF that is routed to the NUMA node to which the VM's VCPUs are pinned. Infra and Mail VMs are assigned VFs round-robin from the physical functions listed above.
• After the system booted, 1GB huge pages were manually allocated on the NUMA nodes. 336 hugepages were each allocated on nodes 0 and 2. 358 huge pages were allocated on node 1. 337 huge pages were each allocated on nodes 4, 5, 6, and 7.
• 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:

• Eight client systems each host thirteen prime client VMs. One client system hosts twelve prime client VMs. One client system hosts the prime controller VM.
• Each prime client VM has 6 VCPUs, 9 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.

Power Configuration Notes

• The SUT has four power distribution units (PDUs) each with its own power cable.
• The two power meters were each connected to two of the SUT's power cables.
• There is no power meter for external storage because there is no external storage.

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 four 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 SFP+ DAC 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.
