  • Page 59: Logical Volumes

    Logical volumes A logical volume is the storage medium that is associated with a logical disk. It typically resides on one or more hard disk drives. For the storage unit, the logical volumes are defined at logical configuration time. For count-key-data (CKD) servers, the logical volume size is defined by the device emulation mode and model.

  • Page 60: Lun Calculation

    Managed EAM Once a volume is managed by Easy Tier, the EAM of the volume is changed to managed EAM, which can result in placement of the extents differing from the rotate volume and rotate extent rules. The EAM only changes when a volume is manually migrated to a non-managed pool.

If the number of cylinders that you specify is not an exact multiple of 1113 cylinders, then some space in the last allocated extent is wasted.

  • Page 66: Easy Tier: Automatic Mode

    1. Easy Tier features include extendable support in automatic mode for FC (enterprise class) and SATA storage tiers. 2. SATA drives are not available for DS8800 in SAS 2, 2.5” form factor. 3. For version 6, release 2 and later, the top tier in a three-tier configuration can only be SSD.
  • Page 67 This now includes support for extent pools with three tiers (SSD, SAS Enterprise, or Near-line SAS for DS8800 and SSD, FC, or SATA for DS8700). With the latest enhancements to Easy Tier you can use automatic mode to help you manage the thin provisioning of your ESE FB volumes.
  • Page 68 Warm demotion Warm demotion operation demotes warm (or mostly sequential-accessed) extents in SSD to HDD, or from Enterprise SAS to NearLine SAS drives (DS8800) to protect the drive performance on the system. Warm demotion was first available in version 6, release 1, the second release of Easy Tier. In both this release and the previous release, the ranks being demoted to are selected randomly.
  • Page 69 Cold demotion Cold demotion recognizes and demotes cold or semi-cold extents to an appropriate lower-cost tier. Cold extents are demoted in a storage pool to a lower tier as long as that storage pool is not idle. Cold demotion occurs when Easy Tier detects any of the following scenarios: v Extents in a storage pool become inactive over time, while other data remains active.

  • Page 70: Easy Tier: Manual Mode

    Easy Tier: manual mode Easy Tier in manual mode provides the capability to migrate volumes and merge extent pools, under the same DS8700 and DS8800 system, concurrently with I/O operations. In Easy Tier manual mode, you can dynamically relocate a logical volume between extent pools or within an extent pool to change the extent allocation method of the volume or to redistribute the volume across new ranks that have been added.
  • Page 71 Functions and features of Easy Tier: manual mode This section descries the functions and features of Easy Tier in manual mode. Volume migration Volume migration for restriping can be achieved by: v Restriping - Relocating a subset of extents within the volume for volume migrations within the same pool.

  • Page 75: Easy Tier Considerations And Limitations

    Limitations The following limitations apply to the use of Easy Tier for DS8700 and DS8800: v TSE logical volumes do not support extent migration. This means these entities do not support Easy Tier manual mode or Easy Tier automatic mode.

    When a host system requests IBM HyperPAV processing and the processing is enabled, aliases on the logical subsystem are placed in an IBM HyperPAV alias access state on all logical paths with a given path group ID. IBM HyperPAV is only supported on FICON channel paths.

  • Page 77: Copy Services

    With multiple allegiance, the storage unit can execute concurrent, multiple requests from multiple hosts. Traditionally, IBM storage subsystems allow only one channel program to be active to a disk volume at a time. This means that, once the subsystem accepts an I/O request for a particular unit address, this unit address appears "busy"...

The following Copy Services functions are available as optional features: v Point-in-time copy, which includes IBM System Storage FlashCopy and Space-Efficient FlashCopy The FlashCopy function enables you to make point-in-time, full volume copies of data, so that the copies are immediately available for read or write access.

    When managing a single-tenant installation, the partitioning capability of resource groups can be used to isolate various subsets of an environment as if they were separate tenants. For example, to separate mainframes from distributed system servers, Windows from UNIX, or accounting departments from telemarketing. Using resource groups to limit Copy Service operations Figure 15 illustrates one possible implementation of an exemplary environment that uses resource groups to limit Copy Services operations.

  • Page 97 To use data encryption, a DS8000 must be ordered from the factory with all IBM Full Disk Encryption drives. At this time, DS8000 does not support intermix of FDE and non-FDE drives so additional drives added to a DS8000 must be consistent with the drives that are already installed.
