    Reprotect in the SRM. Concept diagram The IBM DS8000 storage system can use the IBM DS8000 SRA add-on that works with each instance of VMware vCenter SRM (protected or recovery). Figure 1 shows how the IBM DS8000 Storage Replication Adapter is integrated in a typical VMware SRM disaster recovery solution.

  • Page 12: System Requirements

    Metro Mirror/Global Mirror must be activated at both the protected and recovery sites. v The DS8000 storage must run on microcode version 6.3.2 (DS8800) or version 7.0 and later (DS8870). v The space-efficient (SE) volumes feature must be enabled on the DS8000, if you want DS8000 SRA to use SE volumes during test failover operations and backup in failover operations.

    DS8000 storage system at the recovery site and are visible by that DS8000 storage system. v The name of each DS8000 storage system is unique on both the protected and recovery sites. v The storage extent pools that contain the replicated volumes at both sites have sufficient free capacity for creating the snapshots of all replicated volumes concurrently.

    Attention: Confirm with your storage administrator that all the requirements are met. Verifying the VMware vCenter SRM installation Before you install the IBM DS8000 SRA, ensure that the VMware SRM is installed. The VMware SRM must be accessible at the protected (primary) and recovery (secondary) sites.

    Chapter 4. Configuration IBM DS8000 SRA works with Metro Mirror, Global Mirror (with or without master ® and subordinate), Metro-Global Mirror, and IBM Tivoli Storage Productivity Center for Replication Coexistence. A shortcut that is named IBMDS8000SRAUtil.exe is created on the desktop during the DS8000 SRA installation.

  • Page 28: Configuration Of Ds8000 Remote Copy For Sra

    The DS8000 Command Timeout specifies the maximum time, in seconds, to wait for a required state of volume, command results, FlashCopy, or remote copy. The wait is after certain DS8000 commands run, or to wait for command results. For example: v SRA waits for the volume initialization to be completed before it establishes a FlashCopy relationship.
