Intel AS/400 RISC Server, 170 Servers, 7xx Servers manual 19.7 AS/400 NetFinity Capacity Planning

NOTE:

It is very difficult to predict the improvement of adding storage to a pool, even if the potential gain calculated above is high. There may be instances where adding storage may not improve anything because of the application design. For these circumstances, changes to the application design may be necessary.

Also, these calculations are of limited value for pools that have expert cache turned on. Expert cache can reduce I/Os given more main storage, but those I/Os may or may not be page faults.

19.7 AS/400 NetFinity Capacity Planning

Performance information for AS/400 NetFinity attached to a V4R1 AS/400 is included below. The following NetFinity functions are included:

yTime to collect software inventory from client PCs

yTime to collect hardware inventory from client PCs

The figures below illustrate the time it takes to collect software and hardware inventory from various numbers of client PCs. This test was conducted using the Rochester development site, during normal working hours with normal activity (i.e.. not a dedicated environment). This environment consists of:

y16 and 4Mb token ring LANs (mostly 16)

yLANs connected via routers and gateways

yDedicated AS/400

yTCP/IP

yClient PCs varied from 386s to Pentiums (mostly 100 MHz with 32MB memory), using OS/2, Windows/95 and NT

yAbout 20K of data was collected, hardware and software, for each client

While these tests were conducted in a typical work environment, results from other environments may vary significantly from what is provided here.
