Notes/Summary Of Tuning Parameters

Note: Storage Processors are referenced as SP0, SP1, SP2; File Processors as FP0, FP1,
FP2, FP3; Ethernet Processors as EP0, EP1, EP2, EP3.
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. All files are mounted so that clients equally access Network Processors. 
See Testbed Configuration Filesystem Mount Options.
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
