質問 5

A customer has two Isilon clusters in an Active-Passive setup. The customer has latency sensitive media editing workflows. Most of the media editing work occurs prior to broadcasting between 7:00-8:00, 11:00- 12:00, 17:00-18:00 and 19:00-20:00.
What should be recommended to minimize the risk of including latency to the client workflow?
Response:

（A）Create and set a custom job impact policy that would exclude the running of the Job Engine jobs. Do not run SyncIQ policies during the given hours.

（B）Retain the default job impact policies that would run the Job Engine jobs. Run SyncIQ policies during the given hours.

（C）Create and set a custom job impact policy that would exclude the running SyncIQ policies during the given hours.

（D）Retain the default job impact policies that would run the Job Engine jobs. Do not run SyncIQ policies during the given hours.
