Abstract

Methods, apparatus, and systems for sharing resources across a plurality of computing platforms. Firmware provided on each platform is loaded for operating system runtime availability. Shared resources are presented to operating systems running on the platforms as local resources, while in reality they are generally hosted by other platforms. An operating system resource access request is received by a requesting platform and rerouted to another platform that actually hosts a target resource used to service the resource access request. Global resource maps are employed to determine the appropriate host platforms. Communications between the platforms is enabled via an out-of-band (OOB) communication channel or network. A hidden execution mode is implemented to effectuate data rerouting via the OOB channel such that the method is performed in a manner that is transparent to operating systems running on the platforms. The shared resources include storage, input, and video devices. The method can be used to support shared KVM resources, and shared disk storage.

Description

FIELD OF THE INVENTION

[0001] The field of invention relates generally to clustered computing environments, such as blade server computing environments, and, more specifically but not exclusively relates to techniques for sharing resources hosted by individual platforms (nodes) to create global resources that may be shared across all nodes. BACKGROUND INFORMATION

[0002] Information Technology (IT) managers and Chief Information Officers (CIOs) are under tremendous pressure to reduce capital and operating expenses without decreasing capacity. The pressure is driving IT management to provide computing resources that more efficiently utilize all infrastructure resources. To meet this objective, aspects of the following questions are often addressed: How to better manage server utilization; how to cope with smaller IT staff levels; how to better utilize floor space; and how to handle power issues.

[0003] Typically, a company's IT (information technology) infrastructure is centered aroun...
