>>I have been told that the NT scales to about 1000 devices and the UNIX

These numbers are really low and I don't recognize them. The NetView which
comes with the IT Director product is the only one with a built-in limitation.
Otherwise, the real limitations are the size of the box, cpu and memory, and the
number of operators expected and so on. The UNIX installation manual has an
appendix which deals with sizing equations and we routinely deal with customers
who have well over 20,000 objects -- 50,000 to 60,000 is not uncommon (remember
that objects include boxes, interfaces, networks, and segments) and 80 to 90,000
are not unheard of. Most of these large implementations employ several MLMs to
offload polling to downstream agents.
NetView for NT can handle several thousand objects as well, but it is perhaps a
bit more performance sensitive than UNIX .
But being newer there are no benchmarks that I know of.
I am sorry that I cannot point you to any more definitive information and I urge
you to try the Tivoli web site or the marketing folks to see what they have. I
start my vacation today, so I'm afraid I don't have anything else I can offer.

Subject: NT vs UNIX for NetView 5.1.1???
I know you have probably done this a million times, but I need any WHITE
Papers from TIVOLI or other recommendations you can make on what are the
limitations of the NT vs UNIX Netview 5.1.1.
I have been told that the NT scales to about 1000 devices and the UNIX
scales to 20,000.
I know its not a device but object scaling I need to look at. We think we
are in the 4000 to 7000 object range in our network. Its a world wide,
Frame relay based WAN.
Any response is appreciated
