In accordance with the present disclosure, a system and method for performing a system memory save in tiered or cached storage during transition to a decreased power state is disclosed. As disclosed herein, the system incorporating aspects of the present invention may include a flash or other nonvolatile memory such as a solid-state drive, volatile memory, and at least one alternate storage media. Upon transition to a decreased power state, at least some of the data in the solid-state drive, for example, may be transferred to the at least one alternate storage media. After the SSD data is transferred, data stored in volatile system memory, such as a system context, may be transferred to the SSD memory. With the system context saved in SSD memory, power to the volatile system memory may be turned off.

In accordance with the present disclosure, a system and method are herein disclosed for managing memory defects in an information handling system. In an information handling system, a first quantity of memory, such as RAM, may contain defective memory elements. A second quantity of memory is physically coupled to the first quantity of memory and is used to store a memory defect map containing information regarding the location of defective memory elements in the first quantity of memory. The memory defect map may then be referenced by the BIOS or the operating system to preclude use of regions of memory containing defective memory elements.

A system and method for managing the recovery key of a computer system is disclosed. The computer system includes a security layer, and the recovery key is stored locally to a memory location on the computer system, including, as examples, flash memory on the motherboard of the computer system or a USB port on the computer system. In operation, when it becomes necessary for the computer system to authenticate the recovery key, the recovery key may be retrieved from the local memory. The retrieval and storage of the recovery key may be managed by a remote administrator. The recovery key may be stored in a hidden partition in the storage location, and the recovery key may be cryptographically wrapped to add an additional layer of security.
摘要:
During execution of BIOS at an information handling system, a processor communicates with the storage controller via a command line protocol (CLP) communications channel. Via the channel, the processor obtains identification information for storage devices associated with the storage controller. The processor communicates the identification information to a key management client, which obtains encryption keys based on the identification information from a key management server. The processor receives the encryption keys, and communicates them to the storage controller via the CLP communications channel. The CLP communications channel thus provides a convenient and flexible interface for communication of security information prior to execution of an operating system.
摘要:
A system and method are herein disclosed for managing memory defects in an information handling system. More particularly, a system and method are described for generating a usable memory map which excludes memory locations containing defect memory elements. In an information handling system, a memory defect map, which contains information about the location of defective memory elements, is coupled to the memory device. As a map of memory usable by the system is created, usable memory regions containing defective memory elements are excluded from the memory map. The memory map is passed to the operating system, which uses only those regions of memory designated as usable and non-defective.

A method of routing data in an information handling system can include receiving a notification from a management controller at a basic input/output system (BIOS) that includes a system management interrupt (SMI) handler. The a notification can indicate that the management controller has a data packet bound for a peripheral component interconnect express input/output (PCIe I/O) device coupled to a secondary processor. The method can include generating a system management interrupt at the information handling system via the BIOS SMI handler in response to the notification. The method can also include retrieving the data packet from the management controller via the BIOS SMI handler and sending a payload associated with the data packet from the BIOS SMI handler to the PCIe I/O device.

摘要:
Installable device drivers may be stored on a partition, e.g., Utility Partition (UP) or other OEM partition, of an original equipment manufacturer (OEM) storage device, e.g., hard disk drive, by associating an INT13h Basic Input-Output System (BIOS) interrupt call, e.g., reading from floppy disk drive a: or drive b: a desired storage device driver during the normal course of installing an operating system (OS), e.g., Microsoft Windows, Linux, BSD, Unix, etc., on the information handling system, e.g., personal computer, server, blade server, storage array, workstation, etc. The run-time loading of a raw floppy image having OS installable drivers residing in the Utility Partition or other hidden partition on the hard disk may be presented as a virtual floppy disk drive to the OS installer, e.g., person (manual) or scripted (automated) process.
摘要:
A method for handling memory defects during the POST phase and memory calibration in single processor and multiprocessor information handling systems is disclosed whereby information regarding the location of a known memory defect is utilized to optimize the performance of an information handling system. Memory defects within system memory are identified and replaced during operation with error free memory space.
摘要:
An information handling system including a local event timer operably associated with a management application interface is disclosed. The information handling system can also include a remote event timer accessible by a system management application. The remote event timer can be used relative to use of the local event timer. The information handling system can also include an event timer detection module operable to determine an availability of the local event timer relative to an operating system type. The event timer detection module can also initiate use of the local event timer, and disable use of the remote event timer in response to detecting a local event timer enabled operating system. A method and a chipset configured to be used by an information handling system are also disclosed.
