If you mean the 43P-270, those are nice machines too. I just checked my
files and found various models of 43P at four different customers, and all
were performing fine for small-medium networks. It is available with 1-4
375Mhz
processors, but  the most I saw was two processors. The F50 is a tower,
intended as a server, and can have slow or fast processors; and the 43P is
a
workhorse of a desktop workstation. For your purposes, either one can be
equipped with the processors and memory and disk and network connection
you need, so you can choose based on price performance.

Whether the hardware supports 64-bits is irrelevant so far as I can see.
You
don't need that much precision for NetView, and it runs just fine on an
F50.
What is important in the hardware decision is how many processors you have,
how
fast they are, and how much memory you need.

There are sizing considerations in the back of the NetView Installation
manual
you should look at to see about memory, and the rule about processors is
the
more the better, so long as they are fast (an F50 is better box than a J30
because though an F50 has only 4 processors versus the J30's 8, the J30
processors are only something like 83 MHz while the F50's are 233 MHz.  The
F50
is the performance platform of choice the last time I heard a
recommendation
from Tivoli Performance.

But I am not familiar with the 44P.  To evaluate it you should compare
processors and memory.

And you will also have to get memory  requirements for Cisco works and the
other
Tivoli products you need to run.  Best rule of thumb I ever heard was:
"Determine how much memory you think you will need, double it, and add 20
per
cent".  The second best one I ever heard was "Buy as much as you can
afford.
You cannot be too rich or too thing or have too much memory."   :-)

We are planning for new hardware for Tivoli, Netview and CiscoWorks and
have
been doing comparisons on the F50 to the 44P-270.  Currently the F50 is a
32 bit
processor and the 44P a 64 bit processor.

Most importantly we need to determine if the applications will support 64
bit.

It seems that the trade-offs on the two hardware platforms are the 32bit vs
64bit, disk and memory expansion and number of slots available.

Any advice would be appreciated greatly.
