  • Page 6: Overview

    About Parallel Access Volumes The Parallel Access Volumes (PAV) feature enables an IBM zSeries or S/390 host system to issue multiple I/O requests in parallel to individual logical devices (LDEVs) in the XP7 Storage (XP7) system. Devices used in Parallel Access Volumes operations The two device types used in Parallel Access Volumes operations are base devices and alias devices: •...

    Workload Manager (WLM) and the WLMPAV parameter setting in the HCD file. The XP7 Storage system uses the I-2107 control unit emulation. You can use one of the following modes: • Dynamic Parallel Access Volumes mode For more information about this mode, see Parallel Access Volumes in dynamic mode on page •...

  • Page 8: Parallel Access Volumes In Static Mode

    Parallel Access Volumes in static mode In Parallel Access Volumes static mode, the number of alias devices assigned to each Parallel Access Volumes base device remains the same, even when the number of I/O requests to each device changes. To use static Parallel Access Volumes, set the WLM operational mode to compatibility mode. The WLM operational mode must be set to compatibility mode to support static Parallel Access Volumes operations.

  • Page 9: Wlm In Goal Mode

    WLM supports dynamic and static Parallel Access Volumes operations and manages workloads using one of the following operational modes: • Goal mode For more information about this mode, see WLM in goal mode. • Compatibility mode For more information about this mode, see WLM in compatibility mode. WLM in goal mode The WLM must be in goal mode to support dynamic Parallel Access Volumes operations.

  • Page 10: I/O Request Workflow Using Hyper Parallel Access Volumes

    parallel I/Os is the number of aliases assigned to the base plus 1 for static or dynamic configurations. When HPAV is used, the maximum number of parallel I/Os to a base address is the number of aliases configured in the CU plus 1. If multiple base devices are using aliases, the maximum number for any individual base device is reduced accordingly.

  • Page 11: I/O Request Workflow Using Compatible Super Pav

    As illustrated with the arrows in the figure, I/O requests converge on base device 1 when a host computer accesses the device using PAV. I/O requests are automatically issued to unused alias devices among the nine alias devices in the CU. Similarly, if a host computer accesses base devices 2, 3, and 4, the I/O requests are automatically issued to unused alias devices among the nine alias devices.

  • Page 16: Cautions On Using Compatible Super Pav

    • Increase in the processor availability ratio and delay in the associated I/O processing (increase in the amount of queuing time and response time). • Suspend due to full journal volume caused by data inflow increase. • Overload of the connection path between the primary and secondary storage systems. In particular, in a system that contains a CU (a CU with a high IOSQ at all times) in which alias volumes are always depleted, using Compatible Super PAV causes the increase in the load on the system, and therefore the system balance might be lost.

    Assigning alias volumes to base volumes You can assign aliases to base volumes in XP7 Storage. You can assign up to 255 aliases to a base device in a single CU. Aliases are assigned in the storage system by selecting LDEV addresses that do not have any provisioning (for example, emulated devices such as a 3390-x) assigned to them.
