HP MPX200 Multifunction Router - Manual (Page 8)

1 Introduction
The MPX200-based DMS is block-based data migration that is independent of a SAN, server,
storage protocol (FC and iSCSI), and storage vendor. Because application unavailability during
data migration can critically impact services, DMS is designed to reduce down time. DMS supports
both online (local and remote) and offline data migration across FC and iSCSI storage arrays.
Anyone with knowledge of SAN or SAN storage administration will be able to use DMS.
Important data migration features include the following:
•
FC SAN vendor independent: The MPX200 supports B-Series, C-Series and H-Series fabrics.
MPX200 also supports data migration across multi-vendor FC fabrics.
•
Heterogeneous array support: The MPX200 supports data migration across heterogeneous
arrays (arrays manufactured by different vendors). For a list of the storage array types for
which DMS provides support, see
“Supported storage arrays” (page 16) .
•
Multi-protocol support: The MPX200 supports data migration across multiple storage networking
protocols, including FC and iSCSI. The MPX200 allows data migration between storage arrays
of the same or different protocols.
•
Migration to thin-provisioned storage: The MPX200 supports migration to “thin-provisioned”
storage. During the data migration process, the MPX200 can migrate from regular-provisioned
storage to thin-provisioned storage. When used with space reclamation tools, this type of
storage delivers significant cost savings in deploying new enterprise storage. For more
information, see
“Migration to a thin-provisioned LUN ” (page 29) .
•
Online remote migration: The MPX200 supports online data migration between two remote
data centers. A reasonable bandwidth (fat pipe) between two data centers is required to
handle the initial copy of the data and the change rate during the data copy. The data
migration rate depends on the round-trip latencies between two locations and the available
dedicated bandwidth.
•
Data scrubbing: The MPX200 supports data scrubbing. When retiring the old storage or
redeploying the storage, scrubbing data securely overwrites existing data and ensures that
old data cannot be retrieved.
•
Ease of use: The MPX200 has an intuitive GUI that provides many wizard-based operations
and a CLI. Both GUI and CLI provide user-level protection and ease of use.
•
Data security and sanity: The MPX200 provides features to classify storage arrays as source
only. This classification minimizes the chances of accidental data loss by ensuring that source
LUNs cannot be overwritten. The MPX200 also provides the Verify Migration Job wizard to
compare data on the source and destination LUNs, and to indicate whether the data copy
process occurred without corruption.
•
Migration job scheduling: The MPX200 provides several job scheduling options that minimize
downtime and maximize ease of use.
•
Load balancing: The Load Balancing option allows the aggregation of throughput from storage
array ports, which optimizes migration throughput performance for older-generation,
lower-speed arrays (such as 2 Gb and 4 Gb FC).
•
Data migration service logs: DMS logs are maintained separately from the system logs. DMS
logs are designed to help the service professional maintain a full, detailed history of each job
performed and can be submitted as a part of the migration report to the customer.
•
Data migration service reports: Provide reporting of data migration jobs that have either been
acknowledged or removed from the system. Each migration job entry in the report lists the job
details, including source and destination LUN information.
•
Logging and troubleshooting: System logs are designed to store a significant number of details
that can be used for debugging and troubleshooting. The save capture command, see
