                                IBM System Storage DS8000 Technical Solutions Sample Questions:

                                1. A client has purchased an IBM DS8870to addressitsrequirementsfor both a long-term archive solution managed by a single PowerAIX server, as wellasa separate PowerAIX DB2 database server solution running its OLTP application.
                                The storage that was purchased for these requirements includes 12 managed arrays of 4 TB Nearline drives and 24 managed arrays of 600 GB 15,000 RPM Enterprise drives. The client intends to use the Nearline capacity for its long-term archive and the Enterprise capacity for theOLTPrequirements.
                                What is the logical configuration to implement for this solution?

                                A) Define two extent pools:one pool containing the Nearline ranks and being used to hold all long-term archive LUNs, and one pool containing the Enterprise ranks and being used to hold all of the OLTP server LUNs.
                                B) Define four extent pools, with one pool pair containing Nearline ranks and the other pool pair containing Enterprise ranks. LUNs created for archive purpose should use the Nearline pools evenly and LUNs created for OLTP should use the Enterprise pools evenly.
                                C) Define a single extent pool containing the Nearline and Enterprise ranks and being used to hold all of the archive LUNs and the OLTP LUNs.
                                D) Define four extent pools, with one pool pair containing Nearline ranks and the other pool pair containing Enterprise ranks. DS Storage Manager will automatically direct allocations to the correct pool pair based on which application server the LUNs are associated with.

                                B) Of the four RAID ranks in one HPFE, two could be formatted for Mainframe/CKD, and two could be formatted for Open/FB volumes.
                                C) A HPFE supports encryption.
                                D) There can be up to eight HPFEs in one IBM DS8870.


                                5. Where is the information stored todeterminehas performedremote services on a storage system and to find the time when the service was performed?
