New features¶
Hyper-converged OpenStack compute nodes¶
Implemented full support for colocation of a cluster services on the same host, for example, Ceph OSD and OpenStack compute. To avoid nodes overloading, limit the hardware resources consumption by the OpenStack compute services as described in Deployment Guide: Limit HW resources for hyperconverged OpenStack compute nodes.
LVM block storage¶
TechPreview
Implemented the capability to configure LVM as a back end for the OpenStack Block Storage service.
East-west traffic encryption¶
TechPreview
Implemented the capability to encrypt the east-west tenant traffic between the OpenStack compute nodes and gateways using strongSwan Internet Protocol Security (IPsec) solution.
Tungsten Fabric control interface specification¶
Implemented the capability to specify the TF control service interface for
the BGP and XMPP traffic, for example, to combine it with the data traffic.
Tungsten Fabric 2011¶
TechPreview
Implemented support for Tungsten Fabric 2011.
Full support for SR-IOV in Tungsten Fabric¶
Implemented full support for SR-IOV in Tungsten Fabric.
After the OpenStackDeployment CR modification, the TF Operator
now generates a separate vRouter DaemonSet with specified settings.
After the SR-IOV enablement, the tf-vrouter-agent pods
are automatically restarted on the corresponding nodes causing
the network services interruption on virtual machines running on these hosts.
Therefore, plan this procedure accordingly.
Ceph default configuration options¶
Enhanced Ceph Controller to automatically specify default configuration options for each Ceph cluster during the Ceph deployment.
Disabling of TX offload on NICs used by vRouter¶
Implemented the capability to disable the transmit (TX) offloading using the
DISABLE_TX_OFFLOAD parameter in the TFOperator CR.
targetSizeRatio in KaasCephCluster¶
Implemented the targetSizeRatio parameter for the replicated
MOS Ceph pools. The targetSizeRatio value specifies
the default ratio for each Ceph pool type to define the expected consumption
of the Ceph cluster capacity.
customIngress in KaasCephCluster¶
Added the customIngress parameter to implement the capability to specify
a custom Ingress Controller when configuring the Ceph RGW TLS.
Caution
Starting from MOS 21.3, external Ceph RGW service is not supported and will be deleted during update. If your system already uses endpoints of an external RGW service, reconfigure them to the ingress endpoints.

Improvements to StackLight alerting¶
Implemented the following OpenStack service-level alerts on public/ingress endpoints:
