Subject: Re: [foxboro] P92 Quad KVM Extension

Shaun,
My solution may not work for you, but I'll chime in here anyway.  We're
going another route for our workstation upgrades.
I'm putting P91s in our cabinets (big cabinets!) and using IGEL 2110 LX
thin clients at the operator stations.  Thin clients have come a very
long way since we struggled with the WYSE ones 4 or 5 years ago.  I'm
pretty pleased with these things, the following is me being
enthusiastic, not a sales pitch or recommendation:

These IGELs have two video outputs so I can run dual headed.  The
resolution runs up to 1920x1440 on the VGA and 1600x1200 on the DVI.
Mine run Linux (the LX model) but they are also available with CE or XP
embedded.  There is a 4 headed version that might work for you in lieu
of KVM extenders, but I've never tried to RDP a really big desktop with
multiple monitors.

I can use these to connect to ALL of my IA boxes - they will get RDP
sessions from my P91s, and X windows from my Solaris 10 and 51 series
boxes.  I can connect to a different server on each head for redundancy,
or I can extend a single desktop across both heads.  I get an XDMCP
session from a 51 series box and run it at 256 colors for DM on session
or head and another XDMCP session from a Solaris 10 box with 65K colors
for FoxView to do side by side evaluations as I migrate from DM to
FoxView - makes it very easy for the operators to show me their
concerns.

Although I do have access to the shell, I haven't needed it, as the
setup & configuration menues are excellent.  For around US$250 I'm very
pleased with these.  They have an evaluation program, so if you want to
try some you don't have to buy first.

My overall plan is to have 2 P91s and a P82 in each major plant area,
and run the 2 headed thin clients in the control rooms off of these,
with each client connecting to two of the servers, one session on each
head.  I'll preserve a local head on each server for engineering or
emergency operator access.  This should let me go from about 50
workstations to 15 over the next few years, and actually improve
reliability in most plant areas.

Cheers,

Kevin
