Logical Partition and Cluster Partition

Logical partition is a logical entity which contain a set of Application Services and a set of Shared Objects to which the App Svcs need to refer to and are either defined locally or have a reference link to the Provider level Shared Objects.


The Provider Level shared objects are shared among all tenants of the provider. These Logical Partitions form a set of configurations equivalent to the Show Running command on ACOS minus the Network and System specific attributes or attributes that are different in the member devices of a cluster (such as weights of partition on a device for a specific VRID for HA failover). Each Logical Partition maps to a slice of Partitions that are the set of shared or L3V Partitions of the same pid with same resource assignments on all member devices of a Cluster.

A Cluster Partition is also a logical entity that holds the logical Partition and adds the Networking and System attributes. As part of Deployment all the attributes that need to be different for each Device Partition (D1:P1 or D2:P2,D3:P2 or D4:P3,D5:P3,D6:P3 in the figure above) are bound to the config to derive the specific config that needs to be programmed on each of the device.

Usage in Harmony Controller

Harmony Controller Services Page

On the Services page are listed all the App Services, Logical Partition against which they are mapped, and the physical Cluster Partition to which these Logical Partitions are mapped.


The following image shows second example where the mapping to a physical cluster has not been made:


ADC Config

All Configurations are grouped by Logical Partition and lists all the App Services that the Logical Partition contains as well as the associated Shared Objects:


Service Configuration using Object Explorer

The Global Object Explorer is a Utility tool in Troubleshooting that can be used to make any type of service configuration by using the Logical Partition:
