Hi All,

Does anybody here on the list have experience with EMC/symmetrix storage units.?

We have our databases on this machine and I have a feeling the the I/O performance is not very good. I can not proof it since I do not have any experience/data/access to that machine. We do however have a very cooperative UNIX group but they also lack experience with performance on this machine.

Who can give me pointers about I/O throughput that can be reached, configuration pittfalls etc..

RS6000 8CPU's and 4Gb memory with storage on EMC/symmetrix. Job takes about 2 hours to complete.

F50 1 CPU 1Gb memory (TEST machine) local disks. same job takes 0.5 hours to complete.
