Hello everyone,

We are migrating our Delphix environment to Exadata. When using a "full" Exadata environment, we are able to leverage the flash included in the storage cell to host heavily used tables. Are we able to leverage the flash storage in the Delphix environment? Will a VDB be able to access and use the flash in the storage cell?

Hi Bill-

I have a short answer and a long answer:

The short answer is that wherever some activity related to Delphix is limited by I/O speed, flash storage should improve that process.

The long answer is that there are some instances where Delphix benefits from faster I/O, and other instances where the benefit is negligible.

When the source database is on a server that uses flash storage, JDBC queries between the Delphix Engine and the source database should run faster. Disk I/O should be faster, and the database should, therefore, return results faster.

On the other hand, a VDB is nfs-mounted from the Delphix Engine by the target server. Even if the target server uses flash for storage, I would not expect much benefit, because Delphix holds those data on the DE. With the possible exception of the Delphix toolkit, Delphix performs very little disk I/O on the target server.

I hope this helps, let me know your progress,
