Physical System Notes

Firmware settings used:
Power.PlatformControlledType=Efficiency - Favor Performance
DevicesandIOPorts.PCI64-BitResourceAllocation=Enable
Using the Emulex BIOS configuration utility the following settings were configured for each of the FCoE ports:
Change 'Advanced Mode' to Enable and 'Personality' to 'FCoE'
Set 'Configure DCBX Mode' to 'CEE'
Select 'Configure CEE FCF Parameters', highlight record 1, and set record state to 'Active'

Storage Notes

The IBM Flex System V7000 Storage Node provides VM disk images for the System under test.
There are 2 storage pools, each pool comprising of 2 RAID5 arrays, and each array has 6 x 200GB SSD. Storage pool 1 contains 5 LUNs, Storage pool 2 contains 2 LUNs. Each LUN has 6 partitions, 1 for each of the 6 VM types in a tile. Hypervisor image is provided by mirrored local-attach 600GB SAS disks.

Virtualization Software Notes

The following boot options were used:
intel_iommu=on iommu=pt selinux=0 elevator=deadline cgroup_disable=memory,blkio
The following services are configured to be disabled during runlevel initialization:
abrt-ccpp, abrt-oops, abrtd, atd, auditd, autofs, certmonger, cgconfig, cgred, cpuspeed, crond, cups, dnsmasq, ebtables, elxdiscoveryd, elxhbamgrd, elxmilid, elxsnmpd, fcoe, ip6tables, iptables, irqbalance, iscsi, iscsid, ksm, ksmtuned, lldpad, netconsole, nfs, ntpd, ntpdate, numad, oddjobd, postfix, psacct, quota_nld, radvd, rdisc, restorecond, rhnsd, rhsmcertd, rngd, rpcsvcgssd, saslauthd, smartd, sssd, svnserve, sysstat, winbind, ypbind
/etc/rc.local was modified to include:
echo 4000000 >/proc/sys/kernel/sched_min_granularity_ns
echo 4000000 >/proc/sys/kernel/sched_wakeup_granularity_ns
echo 32000000 >/proc/sys/kernel/sched_latency_ns
echo 1000000 >/proc/sys/kernel/sched_shares_ratelimit (although present in rc.local the sched_shares_ratelimit is not available in the current RHEL 6.4 config and this command is effectively a noop)
echo NO_WAKEUP_PREEMPT >/sys/kernel/debug/sched_features
for i in `find /sys/devices/system/cpu/ | grep scaling_governor`; do
echo "performance" >$i
done
Network configuration is as follows:
Two software bridges are created (br2 & br6) and each have their own 10Gb port assigned (eth2 & eth6)
The first port (eth0) is for host access.
Configuration file /etc/modprobe.d/be2net.conf for 10Gb Ethernet includes:
options be2net num_vfs=30
23 virtual functions were used for the Web, Infra, App, and DB VMs. Ethernet devices
eth0, eth1, eth4, and eth5 are the 4 physical functions which are used by the host to provide physical transport for the virtual functions.
eth2, eth3, eth6, and eth7 are used by the host to provide FCoE function.
VM configurations are as follows:
All VMs are managed with libvirt and created using virsh utility
All VMs are created with the following XML template (exceptions noted below template)
<domain type="kvm">
<name>$vm_name</name>
<memory>$vm_memory</memory>
<currentMemory>$vm_memory</currentMemory>
<vcpu placement="static" cpuset="$vm_cpumask">$vm_numberofcpus</vcpu>
<cputune>

<input type="mouse" bus="ps2"/>
<graphics type="vnc" port="-1" autoport="yes" keymap="en-us"/>
<memballoon model="none"/>
</devices>
</domain>
Batch & Mail VMs do not use SR-IOV for network adapter, and therefore have the following declaration instead of "hostdev" block above:
<interface type="bridge">
<mac address="$mac"/>
<source bridge="$bridge"/>
<target dev="$target_dev"/>
<model type="virtio"/>
</interface>
VMs are bound to host CPUs via their XML configuration in the following manner:
The 1st dbserver and 2nd dbserver were bound to core0-3,16-19 of NUMA node 0
All VMs of tiles 1,2,3,4 are bound to NUMA node 1
All VMs of tiles 5,6,7 are bound to NUMA node 0
Web, Mail, and Infra VMs have a cputune shares value of 1024
DB and APP VMs have a cputune shares value of 16384
Batch VMs have a cputune shares value of 128
Batch VMs also have a nice value of +10 set by the test automation software (as shown in the SUT running-vms.txt data collection file)
The cgconfig service is started by the test automation software (the default cgroup mount points are shown in the SUT proc/mounts data collection file)

Client Driver Notes

The first client system (Flex System x240) hosts 4 prime clients VMs using Red Hat Enterprise Linux 6.4, the second client system (Flex System x240) hosts 3 prime clients VMs using Red Hat Enterprise Linux 6.4. The third client system (System x3650 M3) is the prime controller.
Each prime client VM has 2 vCPUs, 16384 MB memory, and a 20 GB disk. 1 virtio_net device and 1 virtio_blk device are used in all client VMs. Client VM images are provided from a v7000 storage array via FCoE.

Other Notes

Two IBM EN4093R 10Gb Scalable Switches are installed in switch bays 1 and 2 and two IBM CN4093 10Gb Converged Scalable Switches are installed in switch bays 3 and 4 in the IBM Flex System Enterprise Chassis. The system under test has connectivity to all 4 switches via 8 10-Gigabit Ethernet ports.
The IBM Flex System V7000 Storage Node is also located in the IBM Flex System Enterprise Chassis and has connectivity to all 4 10Gb switches. The IBM Flex System V7000 Storage Node, the System under test, and all clients use FCoE for storage connectivity. An external IBM v7000 Storage controller is used to provide disk images for client VMs and is connected to the first CN4093 10Gb Converged Scalable Switch via 8 Gbps FC.
