Highlights
In the case of a large bank migrat-
ing to new storage arrays, Softek
TDMF was the only option consid-
ered because no other solution
could perform the migration with-
out requiring downtime.
• Large number of volumes — Four hundred volumes had to be moved from the
old to new storage array.
• Budget constraints — The migration budget did not include the anticipated
need for outside consulting resources with migration expertise.
In this case, Softek TDMF technology was the only option considered, because
no other solution could accomplish the migration without requiring downtime.
Using Softek's solution, the bank's migration project was completed on schedule
and required no outside resources so the budget was not affected. And because
no application performance impact or outages were experienced, the bank could
continue to generate revenue during the migration.
Softek solution: local mainframe array-to-array migration
1. Softek TDMF software was installed nondisruptively on the host.
2. Storage administrators, without formal training, used examples in Softek's
manual to perform TDMF initialization, activation and copy tasks.
3. In the first week, administrators migrated 50 percent of volumes to target
storage arrays with no performance degradation. Migration took place
during peak periods of activity because TDMF software has a dynamic
throttling capability that speeds up or slows down migration as applica-
tion requirements change.
4. Refreshes were performed periodically so that updates made to source
volume during the copy phase were made to target volume, ensuring
synchronization between source and target.
