Application Note
Remote Data Migration for iSR6200
1
Introduction
This application note provides instructions for performing remote data migration using the QLogic
iSR6200 Series of intelligent Storage Routers listed in the
Products Affected
table. These routers are
collectively referred to as the
iSR6200
throughout this application note. The iSR6200 command line
interface is referred to as the
CLI
, and the SANsurfer
®
Router Manager utility is referred to as the
GUI
throughout this document.
Remote data migration jobs are run as asynchronous mirror operations. During the initial copying
phase of remote online migration, the iSR6200 tracks I/Os occurring in the already copied blocks by
creating dirty region logs (DRLs). Remote online migration also keeps track of the I/Os after the initial
copying phase and creates DRLs. The DRLs are stored in the data management LUN (DML). After the
initial copying phase is complete, the DRLs are flushed continually.

Prerequisites
Before configuring remote data online migration jobs, you must configure the DML on the iSR6200. If
you choose to migrate to a remote array in the offline mode, you need not create a DML. DMLs created on
one blade are available for remote migration jobs across both blades. You can configure up to eight LUNs
as DMLs. The maximum supported DML capacity is 2TB. For more information, see the
Data Migration
Service for iSR6200 User’s Guide.

Remote Migration Use Cases
The iSR6200 supports the following use cases for remote migration.
provides
details on setting up the iSR6200 for these use cases:
Use Case 1:
The source array is at the local site, and the destination array is at a remote site.
Use Case 1 typically applies to scenarios where the servers in a data center at Site A (the local site)
are moved to a data center at Site B (the remote site) and the data storage associated with the servers
are consolidated with existing or new storage arrays at Site B.

Summary
4 – Configuration SN0051424-00 B 2 Use Case 2: The source and destination arrays are at the local site initially. For Use Case 2, after the initial copying operation, the remote migration is moved to the remote site. The iSR6200 supports a maximum of eight paths per array. When using the topology ...
