Dell PowerStore Importing External Storage to PowerStore Guide

PDF

Non-disruptive import of external storage to PowerStore overview

The software that runs on the PowerStore cluster and manages the entire import process is known as the Orchestrator. In addition to the Orchestrator, host multipath I/O (MPIO) software and a host plug-in are required to support the import process. The host plug-in is installed on each host that accesses the storage to be imported. The host plug-in enables the Orchestrator to communicate with the host multipath software to perform import operations.

The Orchestrator supports Linux, Windows, and VMware host operating systems. The Orchestrator supports the following host MPIO configurations:

  • Linux Native MPIO and Dell PowerStore Import Plugin for Linux
  • Windows Native MPIO and Dell PowerStore Import Plugin for Windows
  • Dell PS Series
    • Dell MPIO in Linux - Provided through Dell Host Integration Tools (HIT Kit) for Linux
    • Dell MPIO in Windows - Provided through Dell HIT Kit for Microsoft
    • Dell MPIO in VMware - Provided through Dell MEM Kit
NOTE:If you are using native MPIO and the Dell HIT Kit is not installed on the hosts, the PowerStore ImportKit must be installed on the hosts to support import to a PowerStore cluster. If the Dell HIT Kit is already installed on the hosts, ensure that the Dell HIT Kit version matches the version listed in the PowerStore Simple Support Matrix. If the HIT Kit version is earlier than the version that is listed in the Simple Support Matrix, it must be upgraded to the supported version.

For the most up-to-date supported versions of the supported combinations of host operating system, multipath software, host protocol to the source and to the PowerStore cluster, and the type of source system for non-disruptive (seamless) import, see the PowerStore Simple Support Matrix document at https://www.dell.com/powerstoredocs.

If the version of the operating environment running on your source system does not match what is listed for non-disruptive (seamless) import in the PowerStore Simple Support Matrix document, you may be able to use agentless import. The Simple Support Matrix also lists the most up-to-date information for supported versions of source systems and operating environment that are required for agentless import.

NOTE: For PowerStore with operating system versions 3.0 or later, the connection from some source systems to the PowerStore cluster for import can be over either iSCSI or FC. The Simple Support Matrix document for PowerStore lists what protocol is supported for the connection between the source system and PowerStore. When FC connections are used between the source system and PowerStore, only FC connections between the hosts and the source system and the hosts and PowerStore are supported. For PowerStore with operating system versions 2.1.x or earlier, the connection from the source system to the PowerStore cluster for import is only over iSCSI.
NOTE:For the most up-to-date supported versions of software, see the Simple Support Matrix document for PowerStore.
