We have a customer that is experiencing slower performance running Oracle DB on ZFSSA ( 7310). OEM shows high User I/O.
Customer has deployed RAC DBs using iSCSI LUNs. Are there any tests to show if NFS is faster than iSCSI?
What values for the should we look for in the analytics to recognize we are reaching the capacity limits of the ZFSSA?
These are vague questions with many possible answers, looking for some pointers to address the issue.
