Sorry Marcy - Tivoli Storagte Manager (TSM). Running the server on an IFL, if
you are backing up any number of files, will drag it down to the ground in
versy short order because of the database. It always amazes me that TSM cannot
do something simple, like backing up 4 or 5 million files per night, without
busting it's database. :)
I moved it from a Linux instance here to an LS20 Dual processor Dual Core Blade
with 8gb od RAM and it is much happier. What took intolerably long times on the
IFL runs in about 1/3 the time on the blade. That surprised me so much that I
spent about three or four weeks testing and proviing it over and over and over.

Subject: Re: [IBMVM] zSeries Linux - White Paper for Management
Hey Paul -
I have the barebones of one, but nothing in shape to publish at this
time. A couple of notes though; Mainframe Linux has most of the same
issues as workstation linux, but benefits greatly from the vast I/O
resourcs of the mainframe. It works better under z/VM than on the bare
metal (LPAR or no LPAR).
It fails miserably only in one situation, and that is where whatever you
are running on it is very compute intensive. For example, Tivoli really
takes a couple of IFLSs to run all by iself, and is, IMNSHO, far better
situated on an xSeries blade or pSeries server.
Also, don't even think of running XWindows clients on it; much better to
write customer Client/Server products, or use a web interface, than to
do that. In general, avoid processor intensive work, like image
manipulation or most scientific computing.
