Hi all,
My main function is as a DBA. Another person manages the server and the SAN.
I just want to know if I should be worried about high disk I/O or is it irrelevant as the I/O "load balancing" will be "taken care" of by the SAN?
For example, I have hdisk1-5 and I can see that there are high disk activity for hdisk1-3 but minimal on hdisk4-5, should I be concern and move database files from hdisk1-3 to hdisk4-5 and spread them around?
FYI, I can account for when hdisk1-3 are busy which is during the data load but while this is expected, I am thinking maybe it will "help the SAN" if I move out some of the database files to the filesystem where hdisk4-4 are assigned to.
Any input will be much appreciated. Thanks in advance.
