G Offline Data Migration; Features Overview - HP StorageWorks 6100 - Enterprise Virtual Array User Manual

G Offline Data Migration

Data Migration Service (DMS) is a block-level, offline, data migration service in the HP StorageWorks
MPX200 Multifunction Router data transport device.

Features overview

The HP StorageWorks mpx Manager for Data Migration Services software is designed to simplify
data migration jobs for minimum downtime, while providing protection against common user errors.
The Data Migration Service technology deployed on the MPX200 software has the following features:
• Fibre Channel SAN vendor independent: The MPX200 supports B-series and C-series Fibre Channel
fabrics. HP StorageWorks mpx Manager allows data migration across multi-vendor fabrics.
• Heterogeneous array support: The mpx Manager for Data Migration Services supports data mi-
gration across heterogeneous arrays (arrays manufactured by different vendors). For a list of the
storage array types for which DMS currently provides support, see
rays" on page 253.
• Ease of use: The mpx Manager for Data Migration Services is simple to use. The graphical user
interface (GUI) and command line interface provide many wizard-based operations and user-level
protection.
• Data security and sanity: The mpx Manager for Data Migration Services provides features to
classify a storage array as source only, making it impossible to write data to that array and thus
minimizing 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.
• Migration job scheduling: Data migration may be disruptive to business-critical applications;
therefore, minimizing application downtime is very important. DMS provides several job
scheduling options, which allows you to complete the time-consuming task of configuring data
migration jobs without requiring any downtime. The different I/O size capabilities for migration
jobs enables you to tune the storage array's performance during sequential read/write operations.
The Load Balancing option is also very useful when dealing with older-generation, lower-speed
arrays (such as 2-Gb an-d 4-Gb Fibre Channel) being migrated to higher speed (4-Gb and 8-Gb
Fibre Channel) arrays using higher-speed (4-Gb and 8-Gb) Fibre Channel switches.
• 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.
• 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 the
"save capture" on page 347) helps to capture the configuration details, system logs, and MPX200
state at any time, and can be used for troubleshooting if the need arises.
• Licensing: DMS licenses provide capacity- (per TB) and array-based licenses. For more information,
see "Data migration licenses" on page 289.
