Notes/Summary Of Tuning Parameters

The adb tool was used to enable UDP checksumming on all load generators.
  adb -w /vmunix /dev/kmem
  udp_cksum?W 1
  udp_cksum/W 1

The Auspex NetServer responds to checksummed requests wih checksummed replies,
by default.

The LADDIS Prime Client was the Server's Host Processor (no router was needed).

All load generators used the same LADDIS mount points list with the same 
/etc/fstab entries.

The filesystems were mounted across the 4 NP's in a round-robin fashion 
(eg. F1 on NP0, F2 on NP1, etc.).

Each Load generator mounted filesystems from 4 different NPs and 4 different SPs.

Network Processors: NP0, NP1, NP2, NP3; Storage Proseccors: SP0, SP1, SP2, SP3.

On all the load generators, udp_sendspac - 32768 and udp_recvspace = 32768.

Detailed Server Description

Network Subsystem
Network Processor (Model NP-III):
    - Dual HyperSPARC (66MHz), 256MB
    - One processor does protocol processing, and the other does filesystem processing
    - 4MB Static RAM
    - 1 MLT3 FDDI Adapter
Number of NP-III processors: 4 

Disk Subsystem & Filesystems
Storage Processor (Model SP-V):
    - M68030 (50MHz), 1MB local memory  
    - 2MB NVRAM Write Accelerator
    - 6 SCSI Channels
    - 30 data disks (4.29GB Seagate "Barracuda") configured
    - 5 Virtual Partitions: Each Virtual Partition stripes across 6 disks (unit-128KB)
      on 6 different channels
    - 5 Filesystems (1 Virtual Partition each)
