摘要:
A management computer controlling operations of computer systems in a number of positions within a chassis is programmed to receive a signal indicating that one of the computer systems has been installed and to determine whether it has been installed in a previously unoccupied position, installed in a previously occupied position, or moved from one position to another. If it has been installed in a previously unoccupied position, an operating system is installed for remote booting; if it has been installed in a previously occupied position, it is allowed to continue booting the operating system used by the computer it replaced; if it has been moved from one position to another, it is allowed to continue booting as before.

A method, system and service for providing on-demand computing power to an owner of a multi-blade computer in a server blade chassis. The server blade chassis is delivered fully populated with server blades to a customer. However, only a portion of the total number of server blades is initially enabled. A management module in the server blade chassis monitors usage of the enabled server blades and associated hardware. If the usage of the enabled server blades exceeds a pre-defined parameter, then additional server blades in the server blade chassis are permanently turned on using the management module and a remotely provided key from the manufacturer of the multi-blade computer.

A method and system for managing a secure network boot of a secondary server (server blade). The server blade sends a request, via an Ethernet switch, for a boot program to multiple Dynamic Host Configuration Protocol (DHCP) servers. One of the DHCP servers responds with an address of at least one Pre-boot Execution Environment (PXE) server that can upload a boot program to the server blade. Only if the responding DHCP server is on a list of known trusted DHCP servers will the Ethernet switch allow the server blade to receive the response from the responding DHCP server, thus allowing the download of a boot program from a PXE server.

An arrangement which eliminates the need to remove a computer system from its packaging in order to initiate a re-imaging process. Particularly, there is broadly contemplated herein the use of a position-sensitive switching arrangement, such as a mercury switch, that is configured to power selected control circuitry in a computer so as to receive additional information or data as needed to update imaging or other aspects of a computer's operating system.

A method and system for managing a secure configuration of a server blade on a network. The server blade has a Remote Supervisor Adapter (RSA) card, which contains a list of trusted Dynamic Host Configuration Protocol (DHCP) servers. A remote manager, which communicates with the RSA card via a hyper-secure network, maintains the list of trusted DHCP servers on the RSA card. When the server blade broadcasts a request for configuration parameters to join the network, a response offer is returned from a DHCP server. If the responding DHCP server is not on the list of trusted DHCP servers contained in the RSA card, then the offer is refused, and another DHCP server's offer is evaluated.

A method and system for managing a download of software from an application server to a client computer depending on a physical location of the client computer. The client computer transmits a real-time Global Position System (GPS) coordinate to the application server. This location is then compared to a list of authorized location ranges associated with the requested application. If the client computer is located within an authorized location range, the application server then downloads the application to the client computer. If the client computer is not within an authorized area, then the application is not allowed be downloaded.
摘要:
A method and system for managing a secure network boot of a server blade. The server blade is part of a server blade chassis, which holds multiple server blades that communicate with outside devices via a Pre-boot eXecution Environment (PXE) enabled network interface card. When a server blade receives a response from a PXE boot server offering a boot program download, a Remote Supervisory Adapter (RSA) card, managed by a remote manager, compares the identity of the responding PXE boot server with a list of trusted PXE boot servers. Only if the responding PXE boot server is on the list of trusted PXE boot servers will the server blade be allowed to use a boot program provided by the responding PXE boot server.

A data processing system and method are described for booting a computer system from a virtual floppy diskette. A native operating system is executed by the computer system which utilizes a native file system. A boot able floppy diskette image is stored on the hard drive. The image includes a second operating system which utilizes a second file system. A master boot record stored on the hard drive is modified to include a boot bit. The boot bit is set in response to a storage of the image. The computer system is then booted from the image in response to the boot bit being set. The native operating system and the native file system are unchanged during the booting of the computer system from the image.

Embodiments of the invention address deficiencies of the art in respect to load balancing for servers having multiple blades and provide a novel and non-obvious method, system and computer program product for load balancing at the blade level for servers having multiple blades. In one embodiment of the present invention, a blade server for performing load balancing may comprise a plurality of blades, each blade coupled with a plurality of outgoing ports. The blade server may further include a blade management module configured for monitoring throughput performance of the server and the plurality of blades, wherein each blade is coupled with a plurality of outgoing ports, instructing a blade to switch from a first outgoing port to a second outgoing port when throughput performance decreases and instructing the blade to switch from the second outgoing port back to the first outgoing port when throughput performance increases.
