What is the purpose of issuing the batch-migrate check-plan command?
A.
Verifies that the source devices are not in a storage view
B.
Verifies that the target devices have no virtual volumes configured
C.
Determines if there is currently enough back-end bandwidth
D.
Determines if the front-end IO rate is below the predetermined threshold
The Answer Is:
C
This question includes an explanation.
Explanation:
The batch-migrate check-plan command in Dell VPLEX is used to determine if there is currently enough back-end bandwidth to carry out a migration plan. This is crucial to ensure that the migration does not negatively impact the performance of other operations within the VPLEX environment.
Back-End Bandwidth: The back-end bandwidth refers to the data transfer capacity between the VPLEX and its connected storage arrays.Adequate back-end bandwidth is essential for migration operations to prevent bottlenecks1.
Migration Plan: Before executing a migration plan created by the batch-migrate create-plan command, it is important to check that the system has the necessary resources, such as sufficient back-end bandwidth, to support the migration without disruption1.
Command Function: The batch-migrate check-plan command analyzes the current system load and the expected load from the migration to determine if the migration can proceed without exceeding the system’s bandwidth capabilities1.
Ensuring Performance: By verifying the availability of back-end bandwidth, the command helps to ensure that the migration will not interfere with the normal operations of the VPLEX system, maintaining overall system performance1.
Pre-Migration Assessment: This command is part of the pre-migration assessment process, which is critical for planning and executing migrations effectively and efficiently within the VPLEX environment1.
The batch-migrate check-plan command is an important tool for administrators to validate the feasibility of migration plans and to ensure that migrations do not adversely affect the performance of the VPLEX system.
