Hi all,
the reason to talk about it is, that I have had a discussion with an other
vendor of a backup product about performance in an SAP enviroment. My
questionsTSM related which are still not answered yet are as follows and maybe
someone can help.
the SAP backup description talks about multiple sessions. These sessions
execute in parallel. Does this mean different ways (different Lan
connections) to the *SM Server? If yes, how is it managed? Can I use a switch in
between? For example 4 times 100Mb out of the node into the switch as an
uplink to 1 Gb link to the server?
a storage device (tape drive) must be associated with a session. Isn't it
possible to write first to a diskpool and migrate then into a library using the
number of drives available in that library? If yes, will the max. number
of drives equal in the number of sessions or is it like Gary explained "one
single migration process per unique node's data in the diskpool"
are there any informations available to get a better knowledge about backup
of SAP date by using TSM .
many thanks in advance
