Notes/Summary Of Tuning Parameters
Note: Storage Processors are references as "SP0,SP1"; File Processors as "FP0,FP1"; Ethernet Processors as "EP0,EP1"
The filesystems were mapped to the File Processors as follows - FP0:F1,F3,F71 FP1:F2,F4,F72,F74
All Load Generators used the same LADDIS Mount Points list with the same /etc/filesystems entries
The LADDIS Prime Client was "client1e". The 7051 acted as the router between networks. ThinNet Ethernet cables/tranceivers were used.
1GB drives are packaged in 1 Disk Modules. Automatic striping between the two drives is provided by the controller using 128K striping width.
Each drive provides 256KB buffer (512KB per Module)
