Other Notes

There are 32 disks (28 filesystems) per disk controller. 8 disks per
logical disk volume (2 logical disk volumes per disk controller): 1 disk
contains filesystem logs, and each of the other 7 contain filesystem data.
The size of each filesystem log is 256MB.
There were 2 external I/O drawers used in this configuration:
The adapters were distributed as follows:
-- I/O drawer #1 (7017-F/C6324): 2 Gigabit Ethernet and 5 SSA adapters
-- I/O drawer #2 (7017-F/C6325): 2 Gigabit Ethernet and 3 SSA adapters
JFS used for the OS, Enhanced JFS used for the test filesystems (F1-F224).
SSA adapters/disks configured in JBOD mode with fast-write enabled.
Using jumbo frames (9000-byte MTU) over Gigabit Ethernet.
Server tuning: Gigabit Ethernet adapter jumbo_frames=yes; vmtune -P 100,
nfs_server_base_priority=80, nfs_max_threads=1024, nfs_socketsize=800000,
nfs_server_clread=0, vmtune -t 100
Client tuning: Gigabit Ethernet adapter jumbo_frames=yes
APAR IY22854 (December 2001 release) applied on AIX 5L V5.1.
The number of NFS daemons (nfsd threads) is dynamic.
