Local UNIX array-to-array migration
In this example, a manufacturing company running a mission-critical Oracle
customer order and tracking system on Solaris needed to move 3TB of legacy
data from an old storage array to a new storage array.
The challenges that the company faced were as follows:
• Limited downtime — Downtime was limited to four hours on the weekend.
• Large volume of data — Application storage spanned ten 300GB volumes.
• Increase in volume size — The planned capacity growth required an increase
in volume size during migration.
The company considered the pros and cons of several different migration
options, including:
• Restore from backup tapes — This option would have required more than
four hours to copy the data, exceeding application downtime restrictions.
• Sun Solstice Volume Manager — This would not support the increase in
volume size.
• Array-based replication — This option would have been expensive to install,
and the company did not plan to use it following the migration. In addition,
firmware upgrades required on the legacy arrays to support the current
array-based replication version would have added downtime and complex-
ity to the project.
• VERITAS Volume Replicator (VVR) — This option would have required
installing the prerequisite VERITAS Volume Manager.
Storage migrations made simple.
