Kuli,

What hardware do you use to attach your ATM network to your mainframe?  Are
you using Classical IP over ATM or LAN Emulation?

Subject:  ADSM V3R1.1.2 Throughput problems.




Hello,

Is there anyone out there running v3r1.1.2 using an ATM backbone?.

We have an MVS server running  OS390 v1R2.

When backing up out AIX clients we get through put of about 2MB/Sec.

This is while running 1 client to 1 server.

We then ran a second backup,to a separate server with exactly the same
parameters on the client and server as the current one running and saw a
dramatic fall in throughput down to about 400k /Sec per client.

Any ideas?

We have gone through all the tuning parameters recommended by IBM and still
get nowhere.

Thanks,

Kuli.
