Grid Infrastructure was installed to use Oracle ASM for DATA and LOG disk groups.
Oracle database processes run in 2 processor sets where each pset is configured with 96 HW strands.
Each process runs in the FX class using /usr/bin/priocntl -s -c FX -i pid PID.
Oracle Log Writer runs in a processor set containing a single core,
and runs in RT class using /usr/bin/priocntl -s -c RT -p 1 -i PID.
Oracle DB writers run in a processor set containing a single core.
The remaining cores were used for HBA and network interrupts.

NIC Tuning for driver and emulator communication:
ndd -set /dev/ixgbe[4/5/2/3] intr_throttling 2000


Configuration Notes:
Four application server instances were hosted in 4 separate Solaris Zones.
The 4 Zones were bound to separate processor sets where each pset consisted of 60 HW strands
using /usr/sbin/psrset -b PSET PID. Interrupts were enabled on remaining HW strands in the default processor set.
Each Zone on the system was configured with 2 subnets.
4x 10 Gbit NIC ports were used for driver requests.
2x 10 Gbit NIC ports were for JDBC access where each NIC was shared with 2 Zones.
Interrupts from the Network controllers were configured across the
processors in the default set using the /usr/sbin/pcitool utility.
Stop intrd.

Mirrored SSDs were used for JMS and server log files.

Configuration Notes:
1x 10 Gbit PCIe NIC port used for DNS requests.
2x 10 Gbit onboard NIC ports were for JDBC access.
Interrupts from the HBAs & Network controller were configured across the
processors in the default set using the /usr/sbin/pcitool utility.
Stop intrd.

External storage configuration:
1x Oracle Server X5-2L configured with 4x 1.6 TB NVMe PCIe SSDs,
2x 600GB SAS-2 Disks, and 1x Sun 16Gb FC Dual Port HBA for the database files.
1x Oracle Server X5-2L configured with 14x 600 GB disks, 1x Sun 16Gb FC

Configuration Notes:
Eight application server instances were hosted in 8 separate Solaris Zones.
The 8 zones were bound to separate processor sets where each pset
consisted of 10 cores using /usr/sbin/psrset -b PSET PID.
