2.2.2. s/390x Hardware Requirements
The following list shows the required and recommended hardware configurations on the s/390x mainframe platform for a Red Hat Satellite server:
CPU
- Required: 1 IFL, either in LPAR configuration or shared through z/VM
- Recommended: 2 or more IFLs on z9 or earlier, 1 or more IFL on z10
Memory
- Required: 4 GB of memory
- Recommended: 8 GB of memory
Storage
- Required:
- 1 GB swap on ECKD DASD
- 1xMod3 ECKD DASD or ≥ 2 GB FCP SCSI LUN for base installation
- A minimum of 40 GB storage per software channel (including
Baseand child channels), in/var/satellite/, configurable at install - A minimum of 10 GB storage for cache files stored within
/var/cache/rhn. See Section 2.4.4, “Caching” for more information.
- Recommended:
- 512 MB swap on VDISK + 1 GB swap on ECKD DASD
- 1xMod9 ECKD DASD or ≥ 2 GB multipathed FCP SCSI LUN for base installation
- A minimum of 40 GB storage per software channel (including
Baseand child channels), in/var/satellite/, configurable at install - A minimum of 10 GB storage for cache files stored within
/var/cache/rhn. See Section 2.4.4, “Caching” for more information.
Database
- See Section 2.3.1, “Database Sizing Requirements” for standard database requirements.
- Embedded Database: A minimum of 12 GB storage for the database repository in the
/var/lib/pgsql/partition. - Managed Database: See Section 2.3.2, “Managed Database Requirements”.
- External Database: See Section 2.3.3, “External Database Requirements”.
Important
Red Hat Satellite 5.6 now stores Embedded Database files within
/var/lib/pgsql/ instead of /rhnsat/. Take in consideration this change of disk location for Embedded Database files for previous Satellite deployments. Ensure to allocate sufficient disk space for the /var/lib/pgsql/ directory.
Other
- z/VM 5.3 or later for kickstart and provisioning of guests.
- VSWITCH or Hipersocket LAN for high speed connections to guests
