OpenSDN (Tungsten Fabric)

This section provides information about deprecated and removed functionality in Mirantis OpenSDN.

OpenSDN HAProxy-based LBaaS

Deprecated	MOSK 27.1
Unsupported	MOSK 27.2
Details	Starting with MOSK 27.1, Octavia Amphora load balancing on OpenSDN becomes generally available (GA). The native OpenContrail (OpenSDN) LBaaS implementation based on HAProxy, which is exposed through the Octavia OpenSDN driver, is deprecated in MOSK 27.1 and becomes unsupported in MOSK 27.2. Mirantis recommends using Octavia Amphora as the load balancing backend for OpenSDN-based deployments. For details, refer to Octavia Amphora load balancing. Existing load balancers that use the OpenSDN HAProxy backend continue to function during the deprecation window. In-place migration of load balancer workloads from the OpenSDN HAProxy provider to Amphora is not supported.

Tungsten Fabric API v1alpha1

Deprecated	MOSK 24.2
Unsupported	MOSK 24.3
Removed	MOSK 25.1
Details	Instead of v1alpha1, MOSK introduces support for the API v2 for the Tungsten Fabric Operator. The new version of the Tungsten Fabric Operator API aligns with the OpenStack Controller API and provides better interface for advanced configurations. In MOSK 24.1, the API v2 is available only for the new product deployments with Tungsten Fabric. Since 24.2, MOSK API v2 becomes default for new product deployments and includes the ability to convert existing v1alpha1 `TFOperator` to v2 during update. For details, refer to Operations Guide 25.1: Convert v1alpha1 TFOperator custom resource to v2 . During the update to the 24.3 series, the old Tungsten Fabric cluster configuration API v1alpha1 is automatically converted and replaced with the v2 version.

Tungsten Fabric analytics services

Deprecated	MOSK 24.1
Unsupported	MOSK 24.2
Removed	MOSK 25.2
Details	Tungsten Fabric analytics services, primarily designed for collecting various metrics from the Tungsten Fabric services, have been deprecated. All greenfield deployments starting from MOSK 24.1 do not include Tungsten Fabric analytics services. The existing deployments updated to 24.1 and newer until 25.2 include Tungsten Fabric analytics services as well as the ability to disable them as described in Deployment Guide 25.1: Disable Tungsten Fabric analytics services. During MOSK cluster update to 25.2, all Tungsten Fabric analytics services are automatically removed and the `spec.services.analytics` section is reset in the `TFOperator` custom resource.
