Oracle processes run in 4 processor sets containing 27 cores in all, using psrset -b pset pid
and each process run in the FX class using /usr/bin/priocntl -s -c FX -i pid
Oracle Log Writer bound to a HW strand within a processor set
containing 4 HW strands using /usr/sbin/pbind -b processor_id pid
and run in the RT class using /usr/bin/priocntl -s -c RT -p 1 -i pid
The remaining 4 cores were used for network and disk interrupt handling

Network configuration:
2x XAUI 10Gbit NICs, 2 onboard 1Gbit NICs, and 1 Quad Gbit NIC
Disk configuration:
1x 4 Gb PCI-E Dual Port FC/AL card attached to an ST3510 FC Array.
Configuration notes:
Eight application server instances were hosted in 8 separate Solaris Containers.
Seven Containers were bound to separate processor sets where each pset
consisted of 4 cores (32 HW threads) using /usr/sbin/psrset -b PSET PID.
The eighth container used the default processor set.
The Solaris Container and Processor Set configuration is in the FDA.
Interrupts were enabled only in the default processor set.
Each Container on the system was connected to 2 subnets.
The first subnet in each container was used for driver access and
connected to the 10 GbE switch.
4 containers shared one 10Gbit NIC for this subnet and 4 containers
shared a second 10Gbit NIC for this subnet.
The second subnet in each container was used for database access
where 2 containers each shared 1 of 4 1GBit NICs for these subnets.
Mounted 2 disk mirror from ST3510 for the server logs and
JMS persistence filestore.
