When delivering a flash storage project, Huawei engineers introduced the arbitration mechanism of HyperMetro to the customer. Which of the following statements is false about the arbitration modes?
This question is a piece of cake. Option A is the false statement, as the preferred site should not always win the arbitration in static priority mode.
I believe option B is false, because in static priority mode, the non-preferred site should automatically take over services if the preferred site fails.
D is definitely the correct answer. In quorum server mode, the storage systems send arbitration requests to the quorum server when the link between them is down.
I think Option B is false. In static priority mode, the non-preferred site should automatically take over the HyperMetro services if the preferred site breaks down.
B) In static priority mode, if the preferred site of a HyperMetro pair breaks down, the non-preferred site does not automatically take over HyperMetro services. As a result, the services stop, and the customer must forcibly start the services at the non-preferred site.
A) If no quorum server is configured, HyperMetro works in static priority mode. When an arbitration occurs, the preferred site wins the arbitration and provides services.
