Hybrid System

A 61000/41000 Security System Hybrid System is a deployment that includes SGMs with different numbers of physical CPU cores. In a Hybrid System, the total number of CoreXL and Performance Pack instances that can run on one SGM is equal to the number of physical installed CPU cores. All SGMs must have the same number of CoreXL instances. The number of Performance Pack instances can be different.

For example, a Hybrid System can contain these SGMs:

How this works:

When an SGM boots, the 61000/41000 Security System makes sure that the number of CoreXL instances on the SGM matches the number defined for all other SGMs. Typically, this information comes from the SMO.

If the SGM has too many CoreXL instances, the system automatically reassigns these instances as Performance Pack instances. If the SGM has insufficient CPU cores, the SGM stays in the Down state. You must manually change the number of CoreXL instances and then reboot the SGM.

To see the number of CoreXL instances defined for ALL SGMs:

Run:

> asg_cores_stats

To manually change the number of CoreXL instances for ALL SGMs:

Run:

> cpconfig corexl instances <num_instances>

Important Notes:

• There is always at least one CPU core configured as a CoreXL instance and one as a Performance Pack instance.
• The maximum number of Performance Pack instances on an SGM is the lesser of Physical cores -1 or 16.
• The maximum number of CoreXL instances on an SGM is Physical cores -1.
• If manual Performance Pack core configuration for one SGM causes an invalid configuration on a different SGM, it automatically goes back to the default Performance Pack configuration.
• It is possible to have overlapping CoreXL and Performance Pack instances, where the number of instances is greater than the number of physical cores. We do not recommend this configuration.
