The Linux File System contains files and directories. On Linux, disk storage appliances are mapped to directories of the file system. The directory an appliance is mapped to is a mount point.
CA Cloud Storage for System z records Virtual Volume data as files on disk storage appliances that are mapped to directories of the file system. Different storage devices can be mapped to different directories or mount points. The collection of mount points that hold the Virtual Volumes is collectively known as the Vault.
CA Vtape can be set up to assign specific virtual VOLSER numbers for new scratch mounts through its data set and data class policy-based filters. You control which disk storage appliance is used for z/OS applications and workloads.
Virtual Volumes are directed to a mount point by volume serial range. You have the flexibility to use one or more mount points by assigning volume serial ranges to those mount points. CA Vtape on z/OS is able to assign virtual volume serial ranges through its data set and data class policy-based filters. You decide what z/OS applications and workloads get assigned to which mount point.
The mount point storage is accessed at local disk speed. You can map each mount point to a different gateway appliance. These appliances provide features such as data compression, data deduplication, data encryption, and data replication. Deciding what features to exploit is up to you.
