Michael, Regarding automation of collecting throughput performance stats directly from SAN switches, I would suggest, although I haven't tried it, that automation is possible through the SNMP agent on most switches. IBM 2109's, for example, I recall have a fairly comprehensive set of data available reporting throughput per port, and an SNMP get script could pull these stats at a given interval to a machine elsewhere on the network. IBM/Tivoli Netview I seem to remember has performance monitoring via MIB's in-built and can automate this fairly easily, even displaying the data in a chart if necessary.
That being said, I'm sure there are dozens of other SAN management tools out there which perform similar performance/stat/event gathering functions - it's just a question of how complex they are, and how much you'd want to pay for them!

This isn't easily automatable, but it is a very accurate representation of what you are seeing in terms of throughput.

Are you just going by the activity log? Thanks! Shawn >>> [EMAIL PROTECTED] 07/08/03 1:34 PM >>> >I'm curious as to what kind of MB/sec throughput people are seeing with TSM and LTO drives. It varies drastically for us based upon the objects being moved, of course. 10-15MB/s / drive is normal for us overall. >How many MB/sec does a migration process produce in your environment? We achieve about 12-14MB/s per drive when performing migration. >Does anyone have any DB's streaming directly to LTO and some figures? Appreciate any feedback Yes, our Exchange boxes stream nicely at about 15MB/s per drive. HTH!
