Maybe someone has already installed/upgraded a configuration
somewhat close to what we will be doing next.  Management wants
to be sure that this will work before issuing a purchase order.
Any information, previous experiences, or pitfalls to avoid would
be appreciated.


Current configuration

swap drives strictly for storage pools (no fault tolerance)

The intent is to backup 25 OS/2 servers (LAN), 10 OS/2 servers across
frame relay, 6 Novell Servers, 4 AIX servers, a handfull of
Windows NT Servers, and approx 850 workstations (windows 3.1 and 95).


Also:
We are looking at alternatives for backing up workstations across
the network (server initiated, forced upon login, overnight, etc).
Has anybody out there designed and/or installed a large workstation
backup scenario?  The workstations involve desktops and laptops...

Another Also:
How many people (full time and part time) are required to
administer/monitor a typical ADSM installation?  What skill
level (expert, advanced, average, entry level) are the people
out there monitoring/administering/designing ADSM?
