HPE StoreOnce Systems can be configured using Catalyst stores as a storage device in the Commvault software.
HPE StoreOnce Catalyst is a data protection optimized interface unique to HPE StoreOnce Systems. It provides higher performance and more flexible control than traditional emulated tape (VTL) targets or NAS Shares. StoreOnce Catalyst is supported over Ethernet and also over Fibre Channel.
Catalyst stores are also available as a cloud based service on demand from the HPE Cloud Volumes Backup Service. Catalyst stores from HPE Cloud Volumes Backup can backup and restore data directly from Commvault software, or copied to, from a StoreOnce appliance using Catalyst Copy.
