Linux Installer - System Requirements
The Linux servers are provided by you. The Linux installer installs the appliance administration console, along with MSS.
Supported Operating Systems
The following operating systems are supported. These versions or greater.
- SUSE Linux Enterprise Server 15 SP4
- OpenSUSE Leap 15.4
- Red Hat Linux 9
- Rocky Linux 9
- Oracle Linux 9
- AlmaLinux 9
Minimum CPU and memory requirements
The following minimum resources are required for each node. These requirements assume that no other production software is installed on the node. If additional software will be run on the node, more resources need to be added to accommodate the other software accordingly.
- 8 CPU Cores
- 16 GB RAM - with swap space disabled
- 100 GB disk space (SSD)
Note
Be sure that a large part of the disk space is available to /var/opt/opentext/csp.
Fast storage
To ensure optimal performance and reliability, the use of a solid-state drive (SSD) or other fast storage solutions is required. Not using SSD based storage may lead to inconsistent behaviors and errors.
Disable swapping
For optimal performance and reliability, swap must be turned off on every node. Please refer to the specific documentation of your Linux distribution for guidelines on how to accomplish this.
Fixed IP address
A fixed, non-changing IP address is required for each node. DHCP (Dynamic Host Configuration Protocol) is supported but the IP must be reserved and cannot change.
Network ports
The following ports must be exposed and available between all nodes:
| Port | Purpose |
|---|---|
| 6443 | Kubernetes API Server |
| 8472 | Virtual LAN |
| 10250 | Kubernetes metrics |
| 2379-2380 | etcd |
The following ports must be exposed for outside access:
| Port | Purpose |
|---|---|
| 443 | Product access |
| 3000 | Security Proxy Server * |
| 8001 | AJP ** |
* The Security Proxy port use is optional.
** The AJP port is used when optionally integrated with Microsoft's IIS web server.
Additional firewall rules
The following source IP ranges must be added to the trusted zones list:
| Source IP Range | Purpose |
|---|---|
| 10.42.0.0/16 | Pod communication |
| 10.43.0.0/16 | Service communication |
Required Third Party Packages
The following third-party Linux packages are required for installation: bash, curl, grep, gawk, wget, jq, haveged, zip, bind-utils, sysstat, strongswan, apparmor-parser, util-linux, iscsi-initiator-utils or open-iscsi, nfs-utils or nfs-common, supportutils or sos
In most supported Linux distributions, these packages will be installed automatically for you during product installation. In the case of Red Hat, you must add the EPEL (Extra Packages for Enterprise Linux) repository in order to gain access to these packages. Specifically, the epel-release repository is required. Some of these packages are platform specific and are not required on all platforms.
Supported web browsers
The following web browsers are supported:
- Google Chrome (recommended)
- Mozilla Firefox (recommended)
- Microsoft Edge
