Where is the data coming from? During the testing I did on LTO vs. SDLT I observed similar behavior. I concluded that the RAID5 set containing my disk storage pools was the bottleneck. The paper is a

If you are using a SAN DATa Gateway to bridge the gap between your FC and SCSI drives then that might be the bottle neck. So it is worth checking it out. Regards, Michael Swinhoe Storage Management G

What you really need to find out is how fast are you sending data to the LTO tape drives. The tape drives can only go as fast as the data stream you send to them. Or as fast as the destination can ac

James, The backup is made from the TDP for R/3 running on the same system as TSM. The backup is around 100 GB. The backup is indeed from the local storage (SSA in mirror). We've already tried the set

Richard -- We run our TSM server on a system that serves as our SAP fallover box, and I've more experience than I'd like with both services running on the same physical system. What I had at the time

Tom, The strange thing is that when I backup the production system (which is connected with two separate Gigabit Ethernet adapaters) to the TSM server I get a higher throughput (34 MB/s instead of 20

You mention 20 MB/sec and that the SAP database is on an SSA array. Well some SSA array's have a maximum throughput of 20 MB/sec. This depends on the adapter, and how you have the SSA array configure

It's not an SSA array, it's a JBOD in mirror. I can't give you more machine details alas (customer confidential). The only details I can give you are: RS/6000 model F80 2 CPU 1 GB memory SAP DB size

Richard, Are you using all the 8 drives of LTO? When the backup is running you type q mount, how many drives you see mounted? On init<SID>.utl, which values are you using for multiplex and maxsession
