Abstract
Embodiments that process data are described. For instance, a method includes receiving, at a first disk management device in a storage system, an access request for accessing data in a plurality of disks associated with the storage system. The method further includes determining whether a first access engine for accessing the plurality of disks in the first disk management device is available. The method further includes redirecting the access request to a second disk management device in the storage system if it is determined that the first access engine is unavailable, wherein a second access engine in the second disk management device is available to access the plurality of disks. By means of this method, effective data access can be performed when an access engine of a disk management device is unavailable, thus realizing a more stable access capability and improving the user experience.
