Overview of Hitachi Cross-OS File
Exchange (FX)
This chapter provides a brief overview FX functions, features, and benefits.
The Hitachi Cross-OS File Exchange (FX) feature enables data stored on the
TagmaStore
® USP subsystems to be converted and transferred between z/OS ®
and open-system platforms and between different open-system platforms. The
FX mainframe-to-open (FXmto) capability enables you to transfer data from
z/OS (mainframe) datasets to open-system files. The FX open-to-mainframe
(FXotm) capability enables you to transfer data from open-system files to z/OS
datasets. The FX open-to-open (FXoto) capability enables you to transfer data
between open-system platforms without being attached to a z/OS host. FX
utilizes special FX volumes which are dedicated to data exchange operations
and are accessed as raw devices to provide the greatest platform flexibility for
multiplatform data exchange.
The Hitachi TagmaStore USP and NSC subsystems support concurrent
attachment to z/OS hosts and multiple open-system platforms, including
UNIX
® based platforms (e.g., Solaris, HP-UX, IBM ® AIX ® ) and PC server
platforms (e.g., Windows NT, Novell ® NetWare ® ). The TagmaStore USP and
NSC subsystems provide high-speed response, continuous data availability,
scalable connectivity, and expandable capacity for both z/OS and open-system
storage. The TagmaStore USP and NSC subsystem can operate with multihost
applications and host clusters, and is designed to handle very large databases
as well as data warehousing and data mining applications that store and
retrieve terabytes of data.
The Hitachi TagmaStore USP and NSC subsystems provide the following host
connectivity options:
• Multiplatform: Both fibre-channel (FC) ports and ExSA™ (ESCON) ports.
• All open: All fibre-channel (FC) ports (no ExSA). This type of subsystem is
called an all-open subsystem. FX can be used on the all-open TagmaStore
subsystems for FXoto file transfers.
