General Requirements

The following tables specify the minimum server and proxy requirements.

Do not use NFS for storage because it does not support SELinux file labeling.

1. Server Requirements

Table 1. Server Requirements for x86-64 Architecture
Software and Hardware	Details	Recommendation
Tumbleweed	Clean installation, up-to-date	Tumbleweed
CPU	-	Minimum 4 dedicated 64-bit CPU cores (x86-64)
RAM	Test or Base Installation	Minimum 16 GB
	Recommended	Minimum 32 GB
Disk Space	`/` (root directory)	40 GB
	`/var/lib/containers/storage/volumes`	Minimum 150 GB (depending on the number and type of the product) 50 GB for each SUSE product and Package Hub * 360 GB for each Red Hat product
	`/var/lib/containers/storage/volumes/var-pgsql`	Minimum 50 GB
Swap space	Systems can benefit from additional swap space. It is recommended to use a swap file instead of a swap partition.	8 to 12 GB

2. Proxy Requirements

Table 2. Proxy Requirements
Software and Hardware	Details	Recommendation
Tumbleweed	Clean installation, up-to-date	Tumbleweed
CPU		Minimum 2 dedicated 64-bit CPU cores
RAM	Test Server	Minimum 2 GB
	Production Server	Minimum 8 GB
Disk Space	`/` (root directory)	Minimum 40 GB
	`/var/lib/containers/storage/volumes`	Minimum 100 GB

Uyuni Proxy caches packages in the /var/lib/containers/storage/volumes/uyuni-proxy-squid-cache/ directory. If there is not enough space available in /var/lib/containers/storage/volumes/uyuni-proxy-squid-cache/, the proxy will remove old, unused packages and replace them with newer packages.

As a result of this behavior:

The larger /var/lib/containers/storage/volumes/uyuni-proxy-squid-cache/ directory is on the proxy, the less traffic there will be between it and the Uyuni Server.
By making the /var/lib/containers/storage/volumes/uyuni-proxy-squid-cache/ directory on the proxy the same size as /var/lib/containers/storage/volumes/var-spacewalk/ on the Uyuni Server, you avoid a large amount of traffic after the first synchronization.
The /var/lib/containers/storage/volumes/uyuni-proxy-squid-cache/ directory can be small on the Uyuni Server compared to the proxy. For a guide to size estimation, see the Server Requirements section.
