Hardware Requirements

For best results, SUSE recommends using YES certified for SLES 15 SP3 or SP4 Hardware with Harvester: https://www.suse.com/yessearch/. Harvester is built on SLE technology and YES certified hardware has additional validation of driver and system board compatibility.

To get the Harvester server up and running, the following minimum hardware is required:

Type	Requirements
Cluster	Minimum of 3 servers in each cluster
CPU	x86_64 only. Hardware-assisted virtualization is required. 8-core processor minimum for testing; 16-core or above is required
Memory	32 GB minimum, 64 GB or above required
Disk Capacity	200 GB minimum for testing (180 GB minimum when using multiple disks); 500 GB or above is required for production.
Disk Performance	5,000+ random IOPS per disk(SSD/NVMe). Management nodes (first 3 nodes) must be fast enough for Etcd. Only local disks or Hardware RAID is supported.
Network Card	1 Gbps Ethernet minimum for testing, 10Gbps Ethernet minimum required for production.
Network Switch	Trunking of ports required for VLAN support

Testing environments with 1 GB NIC / 140 GB disk are not supported
