Support Matrix - Harvester v1.1.0 Support Matrix

Product Lifecycle & Support Phases

Release Released EOM EOL Supported Latest Version
1.1 (latest) Oct 26, 2022 Oct 25, 2023 Dec 25, 2023 Yes 1.1.0

Harvester follows an N -1 support policy (meaning that the 2 most recent minor versions receive security and bug fixes) along with a 26-week release cycle. This results in a release being supported for 14 months (12 months of support and 2 months of upgrade period).


GA to EOM

Upon General Availability of all major and minor releases, products are fully supported and maintained until the End of Maintenance date. Support entails general troubleshooting of a specific issue to isolate potential causes. Issue resolution is pursued through one or more of the following: 

  • Applying configuration changes.
  • Upgrade recommendation to an existing newer version of product.
  • Code-level maintenance in the form of product updates; typically, results in a maintenance release, which is a newer version of product that was not existing at the time the issue was encountered.
EOM to EOL

After a product release reaches its End of Maintenance date, no further code-level maintenance will be provided, except for critical security-related fixes on a request basis. Product will continue to be supported until it reaches End of Life, in the form of: 

  • General troubleshooting of a specific issue to isolate potential causes.
  • Upgrade recommendation to an existing newer version of product - Issue resolution limited to applying configuration changes and/or an upgrade recommendation to an existing newer version of product.
EOL

Once a product release reaches its End of Life date, the customer may continue to use the product within the terms of product licensing agreement.

- Support Plans from SUSE do not apply to product releases past their EOL date.
PHASES DESCRIPTION

Scope of Support

A Harvester support entitlement includes support for the components that are bundled with the Harvester appliance. Certain components such as Longhorn storage are subject to additional usage based entitlement, see SUSE T&C or speak to your Account Executive for details.

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 preferred
Memory 32 GB minimum, 64 GB or above preferred
Disk Capacity 200 GB minimum for testing, 500 GB or above recommended for production. Custom partitioning not supported.
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 recommended for production. 
Network Switch Trunking of ports required for VLAN support

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

We recommend server-class hardware for the best results. Laptops and nested virtualization are not officially supported.
