1-2 Overview of Hitachi Cross-OS File Exchange (FX)
Hitachi USP V Cross-OS File Exchange User’s Guide
• 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, MVS TM 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).
