摘要:
A technique is disclosed for storing an electronic record of the existence of licenses available for use in a network of computers and the deployment status of programs covered by the licenses. License tokens are stored on a license server, and the stored license tokens are used to validate the deployment of applications stored on clients associated with the license server. The license server maintains the license tokens for all licensed applications used by the associated clients and maintains a license file for each client. Periodically, the license file containing token data is sent to the pre-boot environment of each client in the system, e.g., by a synching process. A license-maintenance application residing in the pre-boot environment of each client validates the applications stored on the client by comparing them with the token data in the license file upon the occurrence of a pre-boot process.

Systems and arrangements for remotely selecting a bootable image via a WOL packet for a wake-on-LAN (WOL) capable computer are contemplated. Server-side embodiments include hardware and/or software for determining a client to be managed, determining whether the client is active on the network, and transmitting a WOL packet having a vector, or operating system partition identification (OSPID), to describe a bootable image accessible by the WOL capable computer. Some embodiments may include an OSPID that points to a secure bootable image such as a bootable image on a hard drive, a compact disk (CD) connected to the computer, or other local resource. Client-side embodiments may receive the WOL packet at, for instance, a network interface card (NIC), recognize that the WOL packet includes an OSPID that describes the bootable image to boot, and implement an alternative boot sequence to boot from that bootable image.

A data processing system service includes enabling the system to perform diagnostic processing in response to a system failure and enabling the system to perform corrective action during the automated diagnostic processing to attempt to resolve the system failure. The service further includes configuring the system to generate a trouble ticket containing information characterizing the system failure and any attempted corrective action regardless of whether the corrective action was successful in resolving the system failure. The system may be further enabled to forward the trouble ticket to an external database for analysis and to access the external database to determine whether the detected failure has been encountered previously. The system may be partitioned into two partitions including a diagnostic partition. The system boots to the diagnostic partition following a failure or in response to a request from a user.

A data processing system service and method includes enabling the system to perform diagnostic processing in response to identified system problems and enabling the system to generate a trouble ticket containing machine and problem-specific information. The service and method further include forwarding the trouble ticket to an external server which responds with a unique identifier tied logically to the trouble ticket. The service and method of the present invention requires that requested services such as a help desk call or the return of the system for repair or replacement be obtained only upon presentation of the unique identifier. The system may be partitioned into at least two partitions including a diagnostic partition wherein the diagnostic processing is performed. The system boots to the diagnostic partition upon recognition of a system problem, either automatically or by a user.

A security system for computers defines a control zone using radiation, preferably at radio frequency, having a distinctive characteristic, such as a particular frequency. The zone may be established, for example, at a door exit or other limited passage to a secured area. The radiation triggers a device in the computer that in turn sends out a serial number signal. To further prevent unauthorized removal a personal identification number is required of the person in the zone with the computer, either by key input or an encoded radio signal. A receiver located near the control zone applies the serial number to a table look up computer that triggers an emergency signal if a match to an authorized list of serial numbers for the computer and corresponding person does not occur. The emergency signal activates a transmitter that sends out an emergency radiation signal with a different distinctive characteristic. A second receiver in the computer then responds to the emergency radiation signal to trigger the security logic to render the computer inoperative.

A method and system for booting up multiple PCI peripheral devices, such that the number of bootable PCI peripheral devices is not limited by the amount of computer system memory that is dedicated to storing executable boot code for the peripheral devices. The executable boot code is stored on a Read Only Memory (ROM) on each peripheral device. When a new PCI peripheral device begins to boot up, a check for available memory space in a ROM scan memory address space is performed. If there is not enough available room in the ROM scan memory address space for the new device's executable boot code, then a ROM scan detection logic pages an image of another peripheral device's executable boot code out of the ROM scan memory address space before storing the new device's executable boot code into the ROM scan memory address space.
摘要:
A method and system for correlating location information of a server. More particularly, embodiments of the present invention provide a method that includes causing a node to obtain correlation of a first address of at least one target server with a second address of the at least one target server based on the second address of the at least one target server and a plurality of addresses similar in type to the first address. The method further includes retrieving the correlation from the node. As a result, a client may access the correlated location information and communicate directly with the target server.

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.

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 method, software, and system for loading data from disk include comparing a current sequence of disk I/O requests to data indicative of a previous disk I/O request sequence. Responsive to detecting a match between the current disk I/O sequence and the previous disk I/O sequence, a copy of data blocks accessed during the I/O sequence is stored in a contiguous portion of the disk. Responsive to a subsequent request to data in the disk sequence, the request is mapped to and serviced from the sequential portion of the disk. In one embodiment, the disk sequence represents a boot sequence of the system.
