Abstract
A Network Address Authority (“NAA”) identifier associated with a storage device is generated from an Advanced Technology Attachment (“ATA”) serial number, or other identifier, associated with the storage device. The ATA serial number is received from the storage device and used to generate a unique string having a predefined length. In one embodiment, a hash function is applied to the ATA serial number to produce a unique value from the ATA serial number and a portion of the unique value, such as the least significant three bytes, is used as the string having the predefined length. Additional identifying data is combined with the predefined length string and reformatted to generate the NAA identifier. For example, an eight-byte data packet including a four-bit type identifier, a three-byte OUI and the three-byte predefined length string is generated and subsequently used to identify the storage device to processes or devices.
