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

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).
