Highlights
A Fortune 500 bank chose Softek's
TDMF Windows (IP) software for
its ease of use, price and ability to
maintain continuous application
availability during data migration.
The key migration challenges were as follows:
• Adding new storage — The goal was to free up existing storage and implement
new faster, cheaper storage.
• Limited downtime — The application had a limited downtime window from
12 a.m. to 6 a.m. Saturday morning and from 12 a.m. to 2 a.m. Tuesday
morning — but it was estimated that the full migration would take a week.
• Reconfiguration of a large number of volumes — There were 30 volumes to
be moved, creating potential configuration issues.
The bank considered these options:
• Restore from tape backups — This was not possible due to application avail-
ability requirements.
• EMC Open Migrator — This was initially selected but failed during an early
migration test.
• File-level migration/replication — This was considered but found to be too
expensive and difficult to configure for users lacking expert-level implemen-
tation experience.
Softek's TDMF Windows (IP) software was chosen because of its ease of
use, price and ability to maintain continuous application availability during
data migration.
Softek solution: local Windows array-to-array migration
1. During scheduled Saturday downtime, Softek TDMF software was installed
on the production server. Target volumes were connected to the volume/disk
manager and the system was rebooted to allocate the BAB buffer (RAM)
and register target volume at volume/disk manager. Installation took ten
minutes per server. Application was restarted at the end of scheduled downtime.
