General concepts

This section presents an overview of the Cross-Platform Data Sharing (CDS)

feature of Symantec’s Veritas Storage Foundation™ software. CDS provides you

with a foundation for moving data between different systems within a

heterogeneous environment. The machines may be running HP-UX, AIX, Linux

or the Solaris™ operating system (OS), and they may all have direct access to

physical devices holding data. CDS allows Symantec’s Veritas products and

applications to access data storage independently of the operating system platform,

enabling them to work transparently in heterogeneous environments.

The Cross-Platform Data Sharing feature is also known as Portable Data Containers

(PDC). For consistency, this document uses the name Cross-Platform Data Sharing

throughout.

The following levels in the device hierarchy, from disk through file system, must

provide support for CDS to be used:

Application level.End-user applications

File system level.Veritas™ File System (VxFS)

Volume level.Veritas™ Volume Manager (VxVM)
