PROVIDING A GLOBAL UNIQUE IDENTIFIER FOR A STORAGE VOLUME

摘要

Provided are techniques for providing a global unique identifier for a storage volume. Under control of a storage initiator, a Global Universally Unique Identifier (GUUID) is identified for a storage volume of a storage device in a cloud system storing a plurality of storage devices, wherein the GUUID is generated for use with an ATA over Ethernet (AoE) protocol. The GUUID is stored in bytes of a packet header structure. Metadata is stored in remaining portions of the packet header structure. A request with the packet header structure is sent to a storage target.
