A management controller of a computer platform, determines whether an ownership history of management firmware for the management controller represents multiple owners. The management controller includes a set of one-time programmable elements that represent a first secret. The management controller manages use of the first secret based on the ownership history. The management includes, responsive to determining, by the management controller, that the ownership history represents multiple owners, generating, by the management controller, a second secret to replace the first secret. The management further includes, responsive to determining, by the management controller, that the ownership history represents multiple owners, storing, by the management controller, the second secret in a non-volatile memory and generating, by the management controller, cryptographic keys based on the second secret.

Managing use of management controller secrets based on firmware ownership history

Data is organized in a hierarchical data tree having nodes, and is formatted in human-readable data according to a schema. The data is canonically ordered in correspondence with a canonical ordering of a schema dictionary generated from the schema. The canonically ordered data is encoded into binary, including for each node, removing a label of the node, and adding a sequence number of the node corresponding to the canonical ordering, in binary.

Encoding of data formatted in human readable text according to schema into binary

Techniques for management controllers are provided. In one aspect, a processor of a resource registration service of a management controller may receive, from a resource provider, a resource registration request to allocate a resource object in a data model. The resource registration request may include an indication that the resource object is to be joined to a public resource tree. The processor may then allocate the resource object within the data model. In allocating the resource object, the processor may update the public resource tree to link to the resource object based on the indication.

Techniques for using device provided scripts to convert commands are provided. In one aspect, a scripting engine may be implemented to execute a script provided by a device. The script may convert the command from a first format to a second format. A command may be received in the first format. The script may be executed by the scripting engine to convert the command to the second format.

Device provided script to convert command

A data processing system transforms a physical server into multiple virtual servers. The illustrative data processing system comprises a physical server and a virtualization platform integrated into the physical server that is configured to run multiple operating systems simultaneously one or more physical servers. A baseboard management controller integrated into the physical server controls the virtualization platform and the operating systems including physical and virtual resources. The virtualization platform operates according to state data accessed from the baseboard management controller.

Server virtualized using virtualization platform

In one embodiment, a computer system comprises a host machine comprising a plurality of compute resources, at least one management processor, a hypervisor, at least one persistent state data store location coupled to the host machine, wherein the persistent state data store location stores configuration data for the hypervisor, and a persistent state module coupled to a management processor coupled to the host machine, wherein the persistent state module maps hypervisor configuration data to a persistent state data store.

Method and apparatus for configuring a hypervisor during a downtime state

A method and apparatus for booting a system are provided. The apparatus may comprise a boot block and a baseboard management controller coupled together in the system. The baseboard management controller may be configured to receive a request from the boot block for a basic input/output system image; determine at least one location to access the basic input/output system image; and obtain the basic input/output system image from the at least one location.

Apparatus and method for booting a system

A data processing system enables configuration of a virtual connect functioning in combination with a virtualization platform. The illustrative data processing system is used with a virtualization platform which is configured to run multiple operating systems simultaneously on one or more physical servers and a virtual connect device which is communicatively coupled to the virtualization platform. The virtual connect device virtualizes connections between the physical server or servers and a network infrastructure. The data processing system comprises a configuration manager that integrates migration and failover of virtual machines operating under the virtualization platform with migration and failover of physical servers operative under the virtual connect device for management of virtual and physical migration and failover using common commands.

Virtualization platform configured with virtual connect control

The specification discloses a structure and related method for determining whether a particular BIOS routine is supported on a computer system, and if so, the service number for that BIOS routine. This determination is made by a software program accessing a table which correlates unique identification numbers for each BIOS routine with a BIOS call service number. The presence or absence of a unique identification number in the table is an indication to the calling program whether the BIOS implements the desired BIOS routine. If the unique identification number exists in the table, it thus identifies the service number for the particular BIOS routine.

Entrypoint discovery techniques in a bios entity

The disclosed embodiments relate to the field of remote server management. More particularly, the embodiments relate to providing an embedded JTAG master in a remote server management controller. In an exemplary embodiment, the JTAG master is adapted to perform command and control functions on a wide range of integrated circuit components within a managed server. The JTAG master may also be configured to provide communication according to the In-Target Probe (ITP) and In-Circuit Emulation (ICE) test methodologies.

Method and apparatus for providing JTAG functionality in a remote server management controller

A christmas tree to control the production from a subsea oil or gas well is disclosed. The christmas tree design including a tree body having a first flow port and a tree cap; a tubing hanger landed within the tree body; an actuation mandrel landed within the tree body, the actuation mandrel having a flow port; and a flow diverter disposed within the tree cap to divert flow through the flow port. The christmas tree arrangement allows for dual barriers within the tree cap without placing or retrieving any plugs from within the tubing hanger, thereby reducing the number of downhole trips required to complete and/or service the subsea well.

A computer system provides a unified password prompt for accepting a user power-on password or an administrator password. A password string entered by the system administrator at the unified password prompt is compared with a stored power-on password. If the user password string matches the stored power-on password, then access to system resources is granted. If the user password string does not match the stored power-on password, then the user password string is compared to a stored administrator password. If the user password string matches the stored administrative password, then access to system resources is granted. If the user password string does not match the stored administrative password, then the system administrator is given a predetermined number of times to enter a password string matching either the stored power-on password or the stored administrator password. If a password string matching either the stored power-on password or the stored administrator password is not provided in the predetermined number of times, access to system resources is denied. The unified password prompt does not require a system administrator to know a user's power-on password in order to access system resources. The unified password prompt also permits a system administrator to configure a plurality of computer systems by providing a single administrative password rather than a plurality of user power-on passwords.
