Embodiments of the present invention address deficiencies of the art in respect to trusted platform module (TPM) unification in a trusted computing environment and provide a novel and non-obvious method, system and computer program product for trusted platform module data harmonization. In one embodiment of the invention, a TPM log harmonization method can include designating both a single master TPM for a master node among multiple nodes, and also a multiplicity of subsidiary TPMs for remaining ones of the nodes. The method further can include extending the single master TPM with a measurement representing a rendezvous operation for the nodes.

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.

Remote management of boot application

A method for interlocking a plurality of servers to a server system is disclosed. The method comprises assigning an identifier to each of the plurality of servers, wherein the identifier associates each of the plurality of servers to the server system, thereby defining a plurality of interlocked servers.

An aggregated server blade system includes a plurality of individual server blades and a management module which can be designated as a bootable device. A boot list maintained and executed in each server blade includes a management module entry in its list of bootable devices. In response to the management module entry being selected or otherwise made active as the bootable device for a particular blade, an alternative bootable-devices list maintained on the management module is referenced and the boot process proceeds according to the alternative list.

Multi-tiered boot list

A system, computer program product and method for booting to a partition in a non-volatile storage unit without a local operator. In one embodiment, one or more bits in a BOOT register may be set by an operating system indicating if the BIOS should boot to the partition. The BIOS may then read the BOOT register to determine if the BIOS is to boot to the partition as well as any activities to perform if the BIOS is to boot to the partition. In another embodiment, a network interface card may insert directive information received from a packet in a register within the network interface card. The BIOS may then read the register within the network interface card to determine if the BIOS is to boot to the partition as well as any activities to perform if the BIOS is to boot to the partition.

Booting to a recovery/maintenance environment

Methods, systems, and computer program products are provided for glyphword-based security. Embodiments include establishing a glyphword comprising a plurality of glyphs; and creating a plurality of glyphsheets wherein each glyphsheet includes one or more glyphs included in the established glyphword and one or more glyphs not included in the established glyphword; and for each glyphsheet: presenting to a user the glyphsheet; receiving from the user at least one selection of a glyph included in the glyphsheet; determining whether the glyphsheet is the last glyphsheet if the glyph selected by the user is not included in the glyphs of the glyphword; and providing access to a resource if the glyphsheet is the last glyphsheet.

Glyphword-based security

A flash memory is provided that includes a primary flash bank and a secondary flash bank. The primary flash bank includes CRTM logic and BIOS logic and the secondary flash bank comprises a backup copy of the CRTM logic and the BIOS logic. A switching mechanism is configured to selectively activate the primary flash bank or the secondary flash bank.

Providing core root of trust measurement (CRTM) for systems using a backup copy of basic input/output system (BIOS)

A method and system for a failover management module for a server blade chassis. A virtual out-of-band network connects management modules in different server blade chassis. Upon a detection of a failure of the management module(s) in a first server blade chassis, a management module in a second server blade chassis takes over control of the first server blade chassis.

Management module failover across multiple blade center chassis

Embodiments of the invention address deficiencies of the art in respect to boot ROM handling and provide a method, system and computer program product for optimized boot ROM handling for I/O devices. In one embodiment of the invention, a ROM scan area optimization method can be provided. The method can include pre-processing multiple boot ROM images to determine memory space requirements in the ROM scan area for all of the boot ROM images. The method further can include partitioning the ROM scan area into multiple, different static portions and at least one dynamic paged portion. Finally, the method can include generating an optimal arrangement of the boot ROM images defining placement of some of the boot ROM images in corresponding ones of the static portions, and others of the boot ROM images in the dynamic paged portion.

Boot read-only memory (ROM) configuration optimization

A method and system for load balancing switch modules in a server system and a computer system utilizing the same is disclosed. In a first aspect, the method comprises assigning each of a plurality of servers to a switch module of a plurality of switch modules, such that a number of servers assigned to each of the plurality of switch modules is substantially equal. In a second aspect, a computer system comprises a plurality of servers coupled to a plurality of switch modules, a management module, and a load balancing mechanism coupled to the management module, wherein the load balancing mechanism assigns each of the plurality of servers to a switch module of the plurality of switch modules, such that a number of servers assigned to each of the plurality of switch modules is substantially equal.

The invention discloses a method for loading data from a disk. The method may comprise comparing a current sequence of disk requests to data indicative of a previous disk request sequence. Responsive to detecting a match between the current disk sequence and the previous disk I/O sequence, a copy of data blocks accessed during the current disk sequence may be stored in a contiguous portion of the disk. Responsive to a subsequent request for data in the disk sequence, the request may be mapped to and serviced from the sequential portion of the disk: The continuous portion of the disk to which the data is copied may be on a different partition of the disk than a disk partition on which the original data is stored. A sequence of disk accesses may be recorded. Responsive to retrieving data from the continuous portion, additional data from the contiguous portion of the disk may be prefetched and may be cached in a buffer. Responsive to an I/O request, it may be determined whether the requested data resides in the buffer, and if so, the data from the buffer may be retrieved without accessing the hard disk. In an exemplary embodiment, the disk sequence may represent a boot sequence of the system.
