The FastWrite feature is used to optimize the storage transmission protocol. It can reserve cache space for receiving write requests on the target side in advance, saving the () link and reducing the interaction to only one time. The data synchronization delay between arrays is shortened by half, thereby improving the overall active-active solution performance.
