Other Notes

There are 96 disks (80 filesystems) per disk controller. 6 disks per
logical disk volume (16 logical disk volumes per disk controller): 1 disk
contains filesystem logs, and each of the other 5 contain filesystem data.
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=80, nfs_server_clread=0,
nfs_max_threads=400, nfs_socketsize=800000
Client tuning: Gigabit Ethernet adapter jumbo_frames=yes
