Abstract
A hypervisor preferably provides VM (virtual machine) identification, priority and LUN/LBA range information to the HBA (hoist bus adapter) when a VM is created. Alternatively, the HBA can determine that a LUN/LBA range is new and request VM identity, priority and LUN/LBA range from the hypervisor. The HBA creates a table containing the VM identification, priority and LUN/LBA range. The HBA then detects operations directed to the LUN/LBA range and does a lookup to determine VM identification and priority. VM identification and priority are then mapped into a field in a frame using a unique identifier. The unique identifier can be placed using reserved bits on the existing Fiber Channel (FC) header or can use bits in an additional header, such as a modified IFR header or an optional device header. The VM identification aware HBAs register with the NS.
