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
DellPowerStore Import Plugin for Linux
Windows Native MPIO and
DellPowerStore 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
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.
