  • Page 21 (ESS) Models 750 and 800. The DS6000 series has a number of advanced Copy Services functions that are part of the IBM TotalStorage Resiliency family. Copy Services is a collection of functions that provides disaster recovery, data migration, and data duplication functions.
  • Page 22: Flashcopy

    FlashCopy The FlashCopy function enables you to make point-in-time, full volume copies of data, with the copies immediately available for read or write access. You can use the copy with standard backup tools that are available in your environment to create backup copies on tape.
  • Page 23 Multiple Relationship FlashCopy Allows a source volume to have multiple target volumes at the same time. Persistent FlashCopy Allows the FlashCopy relationship to remain even after the FlashCopy operation completes. You must explicitly delete the relationship. Refresh target volume Provides the ability to “refresh” a FlashCopy relationship, without recopying all tracks from the source volume to the target volume.

    (target volumes). Note: Remote mirror and copy was referred to as Peer-to-Peer Remote Copy (PPRC) in earlier documentation for the IBM TotalStorage Enterprise Storage Server. Currently, the remote mirror and copy feature name is used generically for all methods of synchronous and asynchronous methods. In...
  • Page 25 Global Copy Global Copy functions offer a nonsynchronous long-distance copy option whereby write operations to a storage unit at your production site are considered complete before they are transmitted to a storage unit at your recovery site. Global Copy is a nonsynchronous mirroring function and is an alternative mirroring approach to Metro Mirror operations.
  • Page 26 Global Mirror provides a two-site extended distance remote copy option for disaster recovery. With Global Mirror, the data that the host writes to the storage unit at the production (local) site is asynchronously shadowed to the storage unit at the recovery site.
  • Page 27 You can enable the fast reverse option by accessing Copy Services functions from the Web interface called the IBM TotalStorage DS Storage Manager and navigating to the FlashCopy page and then to the Select copy options page.
  • Page 28 Maximum time writes are inhibited to the remote site Indicates the maximum time (in seconds) that write operations are not allowed at the recovery site before the storage unit stops forming a current consistency group. If the drain time is maintained for an extended period of time, the number of write operations that are required to transfer the data to the recovery site can become large enough to increase the time to form a consistency group.
  • Page 29 The automation program is not a part of the software provided with the storage unit; it must be supplied by the user. However, IBM has offerings to assist with this automation. For more information, contact your IBM storage representative.
  • Page 30: Z/Os Copy Services

    There are times, both planned and unplanned, when it is necessary to suspend disk mirroring and to make use of the secondary storage unit in your configuration. As a manual process, this can be complex. However, failover and failback recovery operations are available to simplify this process and reduce the risk of error and the time it takes to switch sites and restart I/O operations.

When selecting RAID disk groups within a cluster for a critical application, spread them across separate device adapters. v Activity to fibre-channel or FICON ports. Use the IBM TotalStorage Multipath Subsystem Device Driver (SDD) or similar software for other platforms to balance I/O activity across fibre-channel ports.
  • Page 32: Count Key Data

    Although sharing resources in the storage unit has advantages for storage administration and resource sharing, there are additional implications for workload planning. The benefit of sharing is that a larger resource pool (for example, disk drives or cache) is available for critical applications. However, you must ensure that uncontrolled or unpredictable applications do not interfere with critical work.
  • Page 33: Parallel Access Volumes

    Parallel access volumes Parallel access volumes (PAVs) allow your system to access volumes in parallel. A PAV capability represents a significant performance improvement by the storage unit over traditional I/O processing. With PAVs, your system can access a single volume from a single host with multiple concurrent requests. You must configure both your storage unit and operating system to use PAVs.

  • Page 39: Licensed Function

    Upon activation, disk drives can be logically configured up to the extent of authorization. As additional disk drives are installed, the extent of IBM authorization must be increased by acquiring additional DS6800 feature numbers (5xxx). Otherwise, the additional disk drives cannot be logically configured for use.
