Disk Space Requirements

CA CSM has the following disk space requirements:

Note: All space allocations are described for 3390 DASD.

For the installation and setup of CA CSM:
- Hierarchical File System (HFS) or zSeries File System (zFS) space = 680 cylinders
  Note: We recommend using zFS file systems. For information about how to migrate from HFS file systems to zFS file systems, see the latest IBM z/OS Migration guide.
- z/OS space = 678 cylinders
  This space contains the CA Datacom/MSM SMP/E environment and runtime libraries. The SMP/E environment contains the CA Datacom/MSM, [assign the DSV variable value for your book], and CA CSM components.
- SDS root space = 100 tracks (approximately)
  For the Software Deployment Service (SDS), the aggregated amount of DASD space for the initial DASD setup is 100 tracks. This amount includes CA CSM and SDS space on the CA CSM host only, and does not include space for the deployment snapshot file system. Additional space is needed for the SDS target system.
- SDS deployment space = 500 cylinders
  For the SDS, each target system needs 500 cylinders of 3390, except CA Database Management Solutions for DB2 for z/OS, which needs 1500 cylinders.
For the operation of CA CSM:
After initial setup, CA CSM allocates additional HFS or zFS files depending on the download of products and maintenance. The amount of space that is allocated varies depending on the number of products and maintenance, and the size of any associated files.
