    Hi All,

    I'm configuring Commvault v11sp18, spanning across two data centers (DC1and DC2).

    Each DC has two physical MediaAgents and one HPE StoreOnce 5650s.

    StoreOnce appliances have few stores created for a particular data type, e.g. DC1-Windows, DC1-Vmware, DC1-SQL etc.

    The primary backup copy should go to StoreOnce at DC1-Windows, then secondary copy (Catalyst Copy) should be replicated to DC2-Windows

    The whole system should be highly available, even in case of one DC1 failure all data should be restored in DC2.

    My question is about GridStor and data paths at the library level sharing.

    What is the difference between Alternate Data Path in Storage Policy and Share Mount path at HPE Catalyst library level?

    What should I use “Alternate Data Path in Storage Policy” or “Share Mount paths at HPE Catalyst library level”? Or may be a combination of both?

    Thanks for suggestions

    Hi Radek 

    While using the HPE StoreOnce are you planning to use the Catalyst Integration for both DC1 and DC2?

    When using Catalyst as a Commvault Library, the MediaAgent will be sending Catalyst API calls to the StoreOnce when doing Backups. This will mean Backups will be leveraging Hardware Side Deduplication


    Note - catalyst also support Commvault Aux Copy, leveraging Catalyst Copy where the two StoreOnce will replicate the data set across the replication network. 


    If you are planning to use HPE StoreOnce Catalyst, then configuring the “Share Mount paths " to both the MediaAgent will be sufficient. So if one MediaAgent is offline, the other online MediaAgent will still have access to the Catalyst Store.
