In Huawei all-flash storage, SmartVirtualization supports online and offline takeover of services. During offline takeover, the connection between the heterogeneous storage system and the application server will be disconnected, and the service needs to be interrupted. However, if online takeover is configured, the connection does not need to be interrupted during the entire takeover process. The service flow will automatically switch after a short interruption, and online takeover can be achieved without the service being aware of it.
