IHAC requirement to migrate nearly 200TB from DMX to Hitachi array
EMC DMX3/4 migration to Hitachi. Current SAN in DMX has VM & physical servers.
(1) Whats the best approach for migration & methodology?
(2) Whats the best tool can be used for migration from Array side?
(3) Whats the best tool can be used for if its host based migration?
Any best practice documents?
Many thanks in advance.
They have many EMC boxes which going to be replaced with VMAX. The 30% of the data would be moved to Hitachi and remaining to EMC VMAX at later stage. My queries are only for Hitachi....... Any thoughts would definitely help!
Welcome to EMC community!
EMC OR hot push can be used for data migration from EMC DMX3 to Hitachi (you can check the support matrix for Hitachi model).
PPME might be a good option only IF Powerpath can manage your Hitachi devices. Kindly refer to support matrix for latest version of Powerpath. If not then EMC Open migrator can do the job.
Hope that helps
When you go out from EMC to Hitachi, its better to check with Hitachi for accurate support.
Otherwise, I would suggest using host based migration like Powerpath Migration Enabler (PPME) which is more time consuming and performance worried than the array based as it consumes host resources. The benefit, with PPME you can switch between source (EMC) and target (Hitachi) before you run the "commit".
