Claim of US Patent No. 9,281,992

1. A method for identifying a storage device, wherein the storage device is in a distributed storage system based on heterogeneous
storage architecture, and identifiers of various storage devices are different, comprising:
obtaining, by a master control server, disk information of a storage device through a storage server;
determining, by the master control server, that there is a storage device matching a device identifier according to the disk
information, and entering a monitoring state; and

determining, by the master control server, that there is no storage device matching a device identifier according to the disk
information, creating a unique device identifier for the storage device randomly so that identifiers of various storage devices
are unified and then various storage devices are managed through unified identifiers and entering the monitoring state;

wherein the determining that there is a storage device matching a device identifier comprises:
comparing the received disk information of the storage device with disk information in an identifier table;
determining that the storage device fully matches the device identifier in the identifier table when the disk information
of the storage device fully matches the disk information in the identifier table;

otherwise, determining that the storage device fuzzily matches the device identifier in the identifier table when a half or
more of the disk information of the storage device matches the disk information in the identifier table.
