摘要
In a method for allocating SAS addresses to SAS expander devices in an SAS expander system, the SAS expander system includes a master SAS expander device, a slave SAS expander device and an EEPROM. The method defines an address parameter for specifying a master SAS address for the master SAS expander device and specifying a slave SAS address for the slave SAS expander device, and obtains an original SAS address from the EEPROM when the original SAS address is identical to either the master SAS address or the slave SAS address. The method adds the address parameter to the original SAS address to generate a first SAS address and allocates the first SAS address to the master SAS expander device. The method adds the address parameter to the first SAS address to generate a second SAS address, and allocates the second SAS address to the slave SAS expander device.
