The Cross-Platform Data Sharing feature is also known as Portable Data Containers (PDC).
The following levels in the device hierarchy, from disk through file system, must provide support for CDS to be used:
|
Application level. |
Veritas™ File System (VxFS) |
File system level. |
Veritas™ Volume Manager (VxVM) |
Volume level. |
Operating system |
Device level. |
CDS is a license-enabled feature that is supported at the disk group level by VxVM and at the file system level by VxFS.
CDS utilizes a new disk type (auto:cdsdisk). To effect data sharing, VxVM supports a new disk group attribute (cds) and also supports different OS block sizes.
Note: |
CDS allows data volumes and their contents to be easily migrated between heterogeneous systems. It does not enable concurrent access from different types of platform unless such access is supported at all levels that are required. |
