Here's some of the performance-related options from one of our dsm.opt's, just for comparison's sake.
TCPBUFFSIZE 127 TCPWINDOWSIZE 64 TXNBYTELIMIT 25600 ResourceUtilization 4 >>> [EMAIL PROTECTED] 2/2/2006 12:38:41 PM >>> Hi all, Netware group at our location is not happy with backup and restore performance using TSM. We are seeing roughly 4 to 5 GB per hour at best. We have tested going to SSA disk pools, SATA disk pools and directly to 3590/3592 tape FC. We don't see very much difference in these methods. Typical Netware client is 150,00+ files with 25 to 40 GB per client. We also have Groupwise and the performance for those is roughly 20 percent worse. Clients are mostly 5.1 and 5.2. TSM servers are P615/4GB ram and P520/4GB ram running AIX 5.2 and TSM server 5.2.3 Most clients are GB Eth and we see similar performance on Windows servers with similar volume sizes/number of files. It seems to me that this is mostly a function of a large number of small files. We also have AIX, Solaris and Oracle clients and performance is generally better on those clients (especially Oracle Rman/TDP). I have looked through the postings and have not been able to glean much of a consensus about what throughput should be for this type of configuration. We have tried many of the parameter changes that have been suggested ( buffer/tcp window sizes, quiet option, etc.) without much success. If anyone has overcome these types of problems or can give me some definitive answers ( even if the answer is 'that's the best you'll get' ), please e-mail me offline.
