Hi All, We are now evluating the IOPS for some DASD (3390-3 and 3390-9). Because the DASD are shared by all LPARs in the sysplex. As per RMF IO activity, there are a few DASDs which were accessed 2000 per second at a specific time. We are afraid there may be hotpot problem occur in the near future.
Is there any reference which clearly states the benchmark or thredhold for the IBM DASD (3390-3 and 3390-9)? The DASD IOPS may be 300 at a specific time in the sysplex. Is it acceptable or do we need to tune that DASD? Looking forward to hearing from you. Thanks! ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
