Calculate a maintenance window duration for update

This section provides an online calculator for quick calculation of the approximate time required to update your MOSK cluster that uses Open vSwitch as a networking back end.

Additionally, for a more accurate calculation, consider any cluster-specific factors that can have a large impact on the update time in some edge cases, such as number of routers, frequency of CPU, and so on.

Number of virtual machines per compute node:

Number of OpenStack compute nodes:

Number of OpenStack gateway nodes:

Number of Kubernetes control plane nodes:

Number of Kubernetes worker nodes except Kubernetes control plane nodes under the Kubernetes worker role:

Boolean, 1 to include or 0 to skip nodes restart:

Total number of nodes in Ceph cluster:

Number of Ceph monitor nodes:

Number of Ceph manager nodes:

Number of Ceph OSD:
