Other Notes

There are 96 disks (84 filesystems) per disk controller. 8 disks per
logical disk volume (12 logical disk volumes per diskcontroller): 1 disk
contains filesystem logs, and each of the other 7 contain filesystem data.
The size of each filesystem log is 128MB.
Using jumbo frames (9000-byte MTU) over Gigabit Ethernet.
Server tuning: Gigabit Ethernet adapter jumbo_frames=yes; vmtune -P 100,
vmtune -r 0 -R 0, nfs_server_base_priority=60, nfs_server_clread=0,
nfs_max_threads=168, nfs_socketsize=800000, nfs_tcp_socketsize=800000
Client tuning: Gigabit Ethernet adapter jumbo_frames=yes
APAR IY09807 required on AIX 4.3.3 (9/99 release) for hardware support.
