not sure if i'd second your conclusion on the "monolithic direction"
subject. For me it seems, TSM is going to evolve further towards a
classic 3-tier client/app/db setup with the first step being the switch
to DB2. There's already the support for a DB2 HADR setup with TSM, so
i expect the appearance of (DB-wise) detached TSM application servers
to be only a matter of time. For me it seems the only way to overcome
the HA, DR and scalability problems TSM has today. I don't know how
exactly TSM development is going to implement this, but it wouldn't
surprise me if a mixed hardware setup - DB2 on AIX/Power in the back
and several application servers on Linux/x86 in front - would be

using ElCheapo cards. We're not there yet ourselfs, just started the
preperations. But from what i can tell right now, it looks like its
going to be a lot harder to utilize the additional bandwith, than back
