Hi Fernando,

Yes you can use only 1 DDB by placing it on the storage Shared.

Thanks,

hello @Ssripada 

Can you send the link where do you find this information?

Thanks

Hello Fernando,

I would prefer to use 2 DDB partitions, one on each MA with SSD (not shared!) for each DDB

@ThomasG 

I need the best practices for this case. 

what is the best solution, indicated by commvault?

Hello Fernando,

Please have a look at Deduplication Building Block Guide (commvault.com)

Best practice is to place the DDB in dedicated local disk.

When you use two cluster nodes: node1 and node2 with MA component on them, then you need to assign the DDB or ddb partition location on the local disk. However if you are planning to use a clustered Media Agent, then the DDB should be located in disk cluster resource for the clustered media Agent not for the physical nodes that are also Media Agents. However a disk cluster resource is not dedicated disk as it is located in storage array.
