Method and Apparatus for Registering and Storing Virtual Machine Unique Information Capabilities

摘要

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 Fibre 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.

1. An apparatus comprising:
a network interface configured to incorporate a unique identifier of a virtual machine into a frame; and a switch coupled to the network interface, the switch configured to provide a unique identifier for a virtual machine, the switch including a fabric name server accessible to the network interface, the fabric name server including a database of devices, wherein the network interface provides virtual machine information to the switch and registers its capabilities of incorporating the unique identifier into frames with the fabric name server, wherein the switch provides a unique identifier to the network interface in response to receiving the virtual machine information from the network interface, and wherein the fabric name server stores the network interface capability in the database of devices.
