Be careful what you wish for in sharing storage - especially if they're running Oracle. We hit something called "sibling pend" at my last site - not DS8K disk, but a different vendor. Had mainframe LUNs and Oracle LUNs on same spindles and whenever the Oracle folks would kick off some kind of replication process. My disk response time would immediately go from 1-2 milliseconds to 500-600 milliseconds. The disk vendor tried to tell me it was the mainframe's fault until I showed them the RMF reports showing the response time. Their response was to provide additional spindles at no charge to segregate the data.

Very interesting update that brought up issues that may become useful to us in the future. If we ever get a unified storage organization at our site, the idea of an onsite/offsite key management would make us look good. The biggest hurdle for me is the 'My Side/Your Side' dichotomy of management. ---- "This is mine", "That is Yours" This is a part of my life here. Since day one of our DS8000 we offered to carve out our excess space as SAN LUNs. You would have thought I was asking to shoot their pet dog. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- The information contained in this message is confidential, protected from disclosure and may be legally privileged.
