"Systems and Methods for Mirroring Virtual Functions in a Chassis Configured to Receive a Plurality of Modular Information Handling Systems and a Plurality of Modular Information Handling Resources" in Patent Application Approval Process

By a News Reporter-Staff News Editor at Information Technology Newsweekly -- A patent application by the inventors Devarapalli, Kiran Kumar (Bangalore, IN); Koladi, Krishnaprasad (Bangalore, IN), filed on January 28, 2013, was made available online on August 7, 2014, according to news reporting originating from Washington, D.C., by VerticalNews correspondents.

This patent application is assigned to Dell Products L.p.

The following quote was obtained by the news editors from the background information supplied by the inventors: "As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option available to users is information handling systems. An information handling system generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes thereby allowing users to take advantage of the value of the information. Because technology and information handling needs and requirements vary between different users or applications, information handling systems may also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information may be processed, stored, or communicated. The variations in information handling systems allow for information handling systems to be general or configured for a specific user or specific use such as financial transaction processing, airline reservations, enterprise data storage, or global communications. In addition, information handling systems may include a variety of hardware and software components that may be configured to process, store, and communicate information and may include one or more computer systems, data storage systems, and networking systems.

"Existing server architectures either provide a single monolithic server capable of running one operating system (or a single hypervisor running multiple virtualized operating systems) and input/output ('I/O') resources at a time, or bulky blade server chassis providing multiple servers and I/O control modules in a single chassis. A system chassis with multiple information handling systems with various peripheral and I/O capabilities common to the chassis as a whole may provide advantages, as it allows a blade server chassis in a small form factor, thereby providing a blade server chassis with a size comparable to the size of a monolithic server. Implementation of a system chassis with multiple information handling systems with various peripheral and I/O capabilities common to the chassis as a whole presents numerous challenges."

In addition to the background information obtained for this patent application, VerticalNews journalists also obtained the inventors' summary information for this patent application: "In accordance with the teachings of the present disclosure, the disadvantages and problems associated with mirroring virtual functions have been reduced or eliminated.

"In accordance with embodiments of the present disclosure, a system may include a chassis and a management processor. The chassis may be configured to receive a plurality of modular information handling systems and a plurality of modular information handling resources. The management processor may be disposed in the chassis and configured to be communicatively coupled to modular information handling systems received in the chassis and further configured to. The management processor may also be configured to expose a first virtual function instantiated on the management processor to a switch interfaced between a modular information handling system and the management processor. The management processor may additionally be configured to communicate an input/output request from the modular information handling system received by the first virtual function to at least one of a second virtual function instantiated on a first storage controller communicatively coupled to the management processor and a third virtual function instantiated on a second storage controller communicatively coupled to the management processor. The management processor may further be configured to receive an acknowledgment of completion of the input/output request from at least one of the second virtual function and the third virtual function. The management processor may also be configured to communicate the acknowledgement to the information handling system via the switch and the first virtual function.

"In accordance with these and other embodiments of the present disclosure, a method may include, in a chassis configured to receive a plurality of modular information handling systems and a plurality of modular information handling resources, exposing a first virtual function instantiated on a management processor disposed in the chassis to a switch interfaced between a modular information handling system and the management processor. The method may also include communicating, by the management processor, an input/output request from the modular information handling system received by the first virtual function to at least one of a second virtual function instantiated on a first storage controller communicatively coupled to the management processor and a third virtual function instantiated on a second storage controller communicatively coupled to the management processor. The method may further include receiving, by the management processor, an acknowledgment of completion of the input/output request from at least one of the second virtual function and the third virtual function. The method may additionally include communicating, by the management processor, the acknowledgement to the information handling system via the switch and the first virtual function.

"Technical advantages of the present disclosure will be apparent to those of ordinary skill in the art in view of the following specification, claims, and drawings.

BRIEF DESCRIPTION OF THE DRAWINGS

"A more complete understanding of the present embodiments and advantages thereof may be acquired by referring to the following description taken in conjunction with the accompanying drawings, in which like reference numbers indicate like features, and wherein:

"FIG. 1 illustrates a block diagram of an example system chassis with multiple information handling systems and with various peripheral and I/O capabilities common to the chassis as a whole, in accordance with embodiments of the present disclosure;

"FIG. 2 illustrates a more detailed block diagram of an example system configured for switches and devices in a multi-root I/O virtualization environment for multiple information handling systems, in accordance with embodiments of the present disclosure;

"FIG. 3 illustrates a virtual stack for I/O communication between an information handling system and target storage controllers, in accordance with embodiments of the present disclosure; and

"FIG. 4 illustrates another virtual stack for I/O communication between an information handling system and target storage controllers, in accordance with embodiments of the present disclosure."
