Migration using CLI
We had to migrate 35TB of Delphix storage from one SAN Array to another. Our main requirement was to perform this migration online without any VDB downtime and ensuring minimal impact to VDB performance. To accomplish this task, we used a Delphix capability: Online Storage migration. It worked seamlessly without any issues and we were able to migrate to the new SAN storage without any impacts to the End-users!!
We first added 35TB of new Storage to Delphix, so for brief time we had both the existing as well as new storage allocated to storage pool, for a total of 70TB. Then we started removing one Device at a time, which took around 7 to 9 hours for each 5TB device to move the data over to the remaining Delphix devices. The nice thing about this capability is the storage de-allocation process works in background and uses minimal memory footprint.
We loved this capability and if you have similar requirement, we would recommend you to use this route. It does not require any additional Delphix appliances.
