摘要： A network and method for servicing simultaneously pending boot image download requests in a multi-client, networked environment. A boot image server on the network is configured to satisfy boot image sessions initiated by one or more client systems on the network. The image server is configured to prioritize requests from different clients to minimize or reduce the network's average download time, which represents the amount of time required to boot a theoretical average client. In one embodiment, the image server is configured to minimize the average download time by prioritizing client requests according to the amount of time required to complete a each client's download such that requests from clients with short remaining download times are given higher priority and, conversely, request from clients with long remaining download times are given lower priority. The amount of download time remaining is estimated by maintaining a log the response time (round trip delay) of recently transmitted packets for each client. In one embodiment, a rolling average of recent response times is used to provide an estimate of the client's overall response time. The image server also tracks the size of the image file remaining to be downloaded for each client. Using these two parameters, the image server estimates the remaining time to download the image file and prioritizes the processing of outstanding packet requests based thereon.

摘要： Aspects for detection and correction of entrance into an improper master boot record (MBR) state in a computer system are described. The aspects include providing a proxy MBR at a predetermined location on a storage device of a computer system to provide a proxy MBR. The proxy MBR is then utilized during a restart operation. An original MBR maintained at an original location on the storage device is then utilized during a reboot operation when the utilization of the proxy MBR is unsuccessful.

摘要： The present invention provides a way to secure data accessed by a software package pre-loaded on a computer system (for delivery to a customer). Specifically, under the present invention, customer data is loaded on a computer system along with any software package(s) that access the customer data prior to shipping the computer system to the customer. Also prior to shipping, a set (e.g., one or more) of passwords for accessing the data such as an administrative password and a hard disk password are set. After the computer system is shipped to the customer, confirmation of proper delivery will be sought. Once this confirmation is received, an access code such as a key or the set of passwords themselves will be shipped to the customer to unlock and use the data.

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.

摘要： A method, system and computer program product for remotely booting devices. A deployment server may remotely transmit authentication parameter(s), e.g., public key, secret key, to a service unit configured to establish a private connection between server blades and the deployment server. The service unit may remotely install the authentication parameter(s) onto the server blade(s) to be booted by either the deployment server or another boot server. By the service unit remotely installing the authentication parameter(s) onto the server blade(s), the need to manually install them during each network boot operation may be alleviated. By remotely transmitting authentication parameter(s) instead of manually installing them on the devices to be booted during each network boot operation, the deployment server may be able to generate unique authentication parameter(s), e.g., public/private key pair, secret key, for each network boot operation thereby substantially reducing the exposure to replay attacks.
摘要翻译：用于远程启动设备的方法，系统和计算机程序产品。部署服务器可以远程地将认证参数（例如，公共密钥，秘密密钥）发送到配置为在服务器刀片和部署服务器之间建立专用连接的服务单元。服务单元可以将认证参数远程安装到服务器刀片上，以由部署服务器或其他引导服务器引导。通过服务单元将认证参数远程安装到服务器刀片上，可以减轻在每次网络引导操作期间手动安装认证参数的需要。通过在每个网络引导操作期间远程发送认证参数而不是手动将其安装在要引导的设备上，部署服务器可以能够生成唯一的认证参数，例如公钥/私钥对，秘密密钥，用于每个网络引导操作，从而显着减少对重放攻击的暴露。

摘要： 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.

摘要： 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.
