Intel 170 Servers User Manual

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.

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

y

Time to collect software inventory from client PCs

y

Time 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:

y

16 and 4Mb token ring LANs (mostly 16)

y

LANs connected via routers and gateways

y

Dedicated AS/400

y

TCP/IP

y

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

y

About 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.
