Highlights
A Fortune 500 financial services
firm chose TDMF UNIX (IP) software
for its migration based on its ability
to migrate between disparate plat-
forms and its flexibility in working
with various logical definitions.
Softek's implementation meth-
odology ensured that there were
no manual errors and the onsite
resources were used efficiently.
Softek's TDMF UNIX (IP) software was chosen based on its ability to migrate
between disparate platforms and its flexibility in working with various logical
definitions. The benefit of the TDMF solution is that the data migration could
be performed in a challenging environment well within scheduled windows.
The firm was finally able to take advantage of its new hardware, which enabled
it to run queries four times more quickly with the new array, improve data
layout, and greatly simplify administration. Most important, end user complaints
about performance were eliminated almost entirely. In addition, the firm was
no longer paying lease charges for unused or outdated hardware. Softek's
implementation methodology ensured that there were no manual errors and the
onsite resources were used efficiently.
Softek solution: multiserver UNIX array-to-array migration with
consolidation
1. In the premigration stage, Softek worked with the storage vendor to perform
comprehensive testing and proof of concept to prove the viability of the migra-
tion strategy. The firm elected to perform migration over scheduled weekend
downtime, with an estimated 24 hours for total migration.
2. In the migration stage, the migration team was given the system at 8 p.m.
on Saturday night; it installed TDMF software on seven AIX hosts in less
than 15 minutes.
3. The migration process was initiated with migration configuration in loop-
back. The actual migration started at 12 a.m. and ended at 4 a.m., moving
22TB of data in four hours.
4. As part of the migration process, the implementation team resized physical
partitions on volume groups, improved the layout of the volumes on the new
array, and resized the IBM Journaled File System (JFS) logs.
5. The system was handed back at 3 p.m. on Sunday, well ahead of schedule,
for preliminary testing. The DB2 data warehouse started correctly and the
verification script launched.
