Firmware settings used:

Storage Notes

All storage accessed with 2 x 4 Gb Fibre Channel links
to DS4800 storage. DS4800 is attached
to 8 EXP3000 SAS enclosures, each enclosure with 16 73 GB SAS drives. Total storage drive
count is 114. There are 14 RAID5 arrays, each consisting of 8 drives. Each array has one
LUN defined for one Tile. Each drive defined for a Tile is divided into 12 logical volumes

Virtualization Software Notes

The following was run after each boot:
echo 242645 >/proc/sys/vm/nr_hugepages
mkdir /dev/hugepages
mount -t hugetlbfs none /dev/hugepages
for i in `seq 0 31`; do echo performance >/sys/devices/system/cpu/cpu$i/cpufreq/scaling_governor; done
The following boot options were used:
elevator=deadline intel_iommu=on iommu=pt pci=assign-busses
Network configuration is as follows:
Two software bridges are created, br0, br1, and the two Broadcom
Ethernet ports are assigned to a bridge (eth0 to br0, eth1 to br1)
For every VM, their first virtIO network device is assigned to one
of these bridges, even number tiles to br0, odd numbered tiles to br1
For each tile, there is another bridge created, name t01....tN
For all Web and Infra VMs, their second virtIO network device is
to a bridge correspnding to thie tile number.
Kernel module for Intel Gigabit ET Server adapter is loaded with
these options to create 42 virtual functions: max_vfs=7,7,7,7,7,7
These virtual functions are assigned (one per VM) to the Web, App
and DB VMs. When a virtual function is present on a VM, a script is
executed to shut down the first virtio_net device and migrate the IP
settings to the virtual function device. This is done to facilitate
easy IP/dns management when using a mix of VMs with and without
virtual functions. The scripts, convert_to_eth[1|2].sh are
available in the disclosure archive.
On the host, Ethernet devices eth2 - eth7 are the 6 physical functions
for the Intel Ethernet ports. These are not used by the host, except
to provide physyical transport for the virtual functions.
All VMs are launched with nice utility (-n 19) to adjust their scheduling priority
VMs on even numbered tiles are are bound to NUMA node 0 and have a preferred memory
allocation node of 0. VMs on odd numbered tiles are are bound to NUMA node 1 and have a preferred memory
allocation node of 1.
All VMs' memory but idle VMs are fulfilled with huge (2MB) pages.
All VMs are created with the following command line format (options in [] are for VMs which have PCI device assignment or hugepages):
/usr/libexec/qemu-kvm -name $name -drive file=$dev1,if=virtio,boot=on,cache=none -drive file=$dev2,if=virtio,boot=off,cache=none
-net nic,model=virtio,vlan=0,macaddr=$macaddr -net tap,vlan=0,ifname=webt01,script=/etc/kvm/qemu-ifup-br$bridge_id
-net nic,model=virtio,vlan=1,macaddr=$alt_macaddr -net tap,vlan=1,ifname=webt01b,script=/etc/kvm/qemu-ifup-t$tile_num
[-pcidevice host=$pci_device] -m $mem -mem-prealloc [-mem-path /dev/hugepages] -vnc :$vnc_port -smp $cpus
-monitor telnet::$monitor_port,server,nowait -serial telnet::$serial_port,server,nowait -daemonize

Red Hat Enterprise Linux 5.5 64bit is the OS used on the clients.

Other Notes

A single Cisco Catalyst switch, model 6500-E is used for all
physical network connections
All VMs were running the 2.6.18-194.el5 Linux kernel.
