Notes/Summary Of Tuning Parameters
Note: Storage Processor is referenced as SP0; File Processor as FP0; Ethernet Processor as EP0.
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
