All mainframe. The TagmaStore subsystems can be configured with all ExSA (no FC ports). This type of subsystem is called an all-mainframe subsystem. FX is not used on the all-mainframe TagmaStore subsystem.

Note: The Hitachi Multiplatform Backup (MBU) feature of the TagmaStore USP and NSC subsystem enables you to implement z/OS-based backup/restore operations (device-level only) for the open-system data stored on the multiplatform TagmaStore USP and NSC. For further information on HMBR, please refer to the Hitachi Multiplatform Backup (MBU) (MK-94RD209) or contact your Hitachi Data Systems account team.

Note: For FAL/FCU versions earlier than 01-XX-50, Multiple Volume Dataset is not supported. When a dataset is spanned over multiple volumes, only the portion of the dataset within one volume will be processed. For FAL/FCU versions 01-XX-50 or later, Multiple Volume Dataset is supported only for FXmto.

Note: FAL/FCU supports two kinds of mainframes, MVSTM and VSE®. For Multiple Volume Dataset, FAL/FCU is only supported on MVS.

Note: When the mainframe OS is VSE, the supported version is 2.3 or earlier.

FX provides the following benefits for the user:

FX provides a centralized data management and disaster recovery environment for both z/OS and open-system data.

FX provides high-speed data transfer over ExSA™ (ESCON ®) and fibre channels, freeing up valuable network resources and communication links for application use.

FX’s high-speed data exchange enables you to implement file-level backup of open-system data to z/OS storage (e.g., using Harbor).
