Hello Norbert,
If you saved any of the rejected email to <lambert@mitvma.mit.edu>, I'd
love to see them to figure out what was broken. Vacation was great but
always too short! :)
We have not implemented IPM for printing to distributed printers. We'll
evaluate that possibility sometime in the future. Out implementation of
IPM allows authenticated file submittals from application servers and
desktops. Due to our authentication requirements, a customized secure
browser interface was developed for desktop submits. klp -- kerberized
lp can also be used from desktops. We're only managing central printers
as this time.
Our network environment on the campus is based on a 10/100Mb/s switched
ethernet topology. All servers, desktops, and printers are connected
via this topology.
You didn't mention anything about business/service recovery. I would
have a number of issues with deploying additional distributed IPM
servers at the branches if the central server can't handle the load.
Have you considered the possibility of running two central servers,
each with say 75% of the capacity to handle your entire load. That
implies you have 150% capacity to handle your production load but also
gives you 75% capacity for handling your most critical work should
one of your two production servers go down. You may have another
whole model for business/service recovery which handles the server
outage problem.
I can't provide a sizing estimate for you. IBM should be able to
do that based upon your print volumes, need for converting one
datastream type to another, and the number/size of the printers you
plan to drive at one time. IBM has a tool to estimate the server size -
both processor size as well as disk.
I'm assuming you don't have to worry about encryption of the data on
your private WAN. That's an issue for our open network but we are
living with an unencrypted solution today.
Hope this helps some...
-Dave
