Use this procedure to ensure that the target system is configured to provide CPU, memory, networking, and storage resources for the incoming source environment.
CPU Resources – During the shift, you can assign any amount of CPU resources to the solaris10 branded zone that are appropriate for the workload. However, prior to the lift and shift, you must ensure that those CPU resources are available as described in this procedure.
If you are uncertain about the CPU utilization of the workload on the target system, then the target system should provide at minimum the same available CPU and memory resources that the solaris10 branded zone had on the source system. This conservative approach helps maintain the same or better performance level of the workload after the migration. On the other hand, if the CPU utilization is estimated to be significantly lower for the branded zone on the target system, for example, if the target system has faster CPUs, then the target system can provide fewer CPU resources to the branded zone. In some cases, using fewer CPU cores reduces software licensing costs.
Memory Resources – By default, the target solaris10 branded zone is allocated the same amount of memory that it had on the source system. Ensure that there is at least the same amount of memory available on the target system, as described in this procedure.
Storage Resources – The number of virtual disks and sizes on the target must match the source system's disk configuration, as described in this procedure.
Network Resources – A network data link created from the global zone to be used by the solaris10 branded zone as its network interface. Redundancy of links can leverage aggregations available from the global zone.
In this example, the target system has 16 cores.
