Notes/Summary Of Tuning Parameters

Note: Storage Processors are referenced as SP0, SP1; File Processors as FP0, FP1; Ethernet Processors as EP0, EP1.
All Load Generators used same LADDIS Mount Points list with same /etc/fstab entries.
The LADDIS Prime Client was the server Host Processor (no router was needed). ThinNet Ethernet cables/transceivers were used.
The adb tool was used to enable UDP checksumming on the IPX load generators.
adb -w /vmunix/dev/kmem
udp_cksum?W1
udp-cksum/W1
