Using the Emulex BIOS configuration utility the following settings were configured for each of the FCoE ports:
Change 'Personality' to 'FCoE'

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 2 RAID5 arrays, and each array having 6 x 200GB SSDs. Storage pool 1 contains 5 LUNs, Storage pool 2 contains 5 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 pci=lastbus=0xff
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 NO_WAKEUP_PREEMPT >/sys/kernel/debug/sched_features
The following items were added in /etc/sysctl.conf:
kernel.sched_min_granularity_ns = 4000000
kernel.sched_wakeup_granularity_ns = 4000000
kernel.sched_latency_ns = 32000000
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
33 virtual functions were used for the Web, Infra, App, and DB VMs. Ethernet devices
eth0, eth1, eth4, and eth5 are the 4 physical functions that are used by
the host to provide physical transport for the virtual functions.
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):
<domain type='kvm'>
<name>$vm_name</name>
<memory>$vm_memory</memory>
<currentMemory>$vm_memory</currentMemory>
<vcpu cpuset='$host-cpu-list'>$vm_vcpus</vcpu>
<os>
<type arch='x86_64' machine='pc'>hvm</type>
<boot dev='hd'/>
</os>
<features>
<acpi/>
<apic/>
<pae/>
</features>
<cpu match='exact'>
<model>Westmere</model>
<feature policy='force' name='x2apic'/>
</cpu>
<clock offset='utc'>
<timer name='pit' tickpolicy='delay'/>
</clock>
<on_poweroff>destroy</on_poweroff>
<on_reboot>restart</on_reboot>
<on_crash>restart</on_crash>
<devices>
<emulator>/usr/libexec/qemu-kvm</emulator>
<disk type='block' device='disk'>
<driver name='qemu' type='raw' cache='none' io='native'/>
<source dev='$vm_disk'/>
<target dev='vda' bus='virtio'/>
</disk>
<hostdev mode='subsystem' type='pci' managed='no'>
<source>
<address domain='0x0000' bus='$bus' slot='$slot' function='$function'/>
</source>
</hostdev>
<serial type='pty'>
<target port='0'/>
</serial>
<console type='pty'>
<target type='serial' port='0'/>
</console>
<input type='mouse' bus='ps2'/>
<graphics type='vnc' port='-1' autoport='yes' keymap='en-us'/>
<memballoon model='none'/>
</devices>
</domain>
Mail and Batch VMs do not use SR-IOV for network adapter, and therefore have the following declaration instead of 'hostdev' block above:
<interface type='bridge'>
<mac address='$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:
All VMs of tiles 1, 2, 3, and 4 are bound to NUMA node 0
All VMs of tiles 5, 6, 7, and 8 are bound to NUMA node 1
App and Db VMs of tiles 9 and 10 are bound to NUMA node 0
Web and Infra VMS of tiles 9 and 10 are bound to NUMA node 1
Mail and Batch VMs of tile 9 are bound to NUMA node 0
Mail and Batch VMs of tile 10 are bound to NUMA node 1
App and DB VMs are reniced -10
Mail and Web VMs are reniced +16

Client Driver Notes

The first and second client systems (IBM Flex System x240) each host 5 prime client VMs using Red Hat Enterprise Linux 6.4. The third client system (IBM 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 an IBM Storwize V7000 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 Storwize V7000 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.
