Introduction
The iSR6200-based data migration service (DMS) is block-based data migration
that is independent of a SAN, server, storage protocol (Fibre Channel and iSCSI),
and storage vendor. Application downtime during data migration is always critical.
DMS supports both online and offline data migration across Fibre Channel and
iSCSI storage arrays. Even offline data migration using DMS is designed to
minimize application downtime by allowing the user to configure all migration
related tasks while the application remains online, and to migrate the data at a
very high speed while the application is offline. DMS is designed such that any
person with knowledge of SAN or SAN storage administration can use this
service.
Important data migration features include following:
Fibre Channel SAN vendor independent: The iSR6200 supports
Brocade
®
/McDATA
®
, Cisco
®
, and QLogic Fibre Channel fabrics. iSR6200
also supports data migration across multi-vendor Fibre Channel fabrics.
Heterogeneous array support: The iSR6200 supports data migration
across heterogeneous arrays (arrays manufactured by different vendors).
For a list of the storage array types for which DMS currently provides
support, see
“Supported Storage Arrays” on page 2-8 .
Multi-protocol support: The iSR6200 supports data migration across
multiple storage networking protocols, including Fibre Channel, iSCSI, and
Fibre Channel over Ethernet (FCoE). The iSR6200 allows data migration
between storage arrays of the same or different protocols.
Ease of use: Manage the iSR6200 using the intuitive graphical user
interface (GUI) that provides many wizard-based operations, and the
command line interface (CLI). Both provide user-level protection and ease of
use. Any SAN administrator or storage administrator can perform safe and
quick data migration.
Data security and sanity: The iSR6200 provides features to classify a
storage array as “source only.” This classification ensures that you cannot
configure LUNs out of this array as destination LUNs, and thus minimizes
the chances of data corruption. It also provides a Verify Migration Job wizard
to compare data on the source LUN with that on the destination LUN to
indicate that the data copy occurred without any data loss or corruption.
