Abstract: 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.

Abstract: DCMI functionality is extended to platforms of a datacenter by integrating a management controller in each of plural platforms and interfacing the management controllers with a management server through a network. End users interface with platforms of the datacenter using DCMI protocol communications. The management server supports communication with management controllers by receiving DCMI messages and translating the DCMI messages to a text-based protocol for communications with the management controllers. In one embodiment, the management controllers push sensor information for their associated platforms to a sensor cache of the management server so that the management sensor references the cache to respond to DCMI requests for sensor information.

Abstract: 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.

Abstract: An information handling system tray component is selected for a depth to fit into chassis support components to provide processing resources in a space having different depths. An end user selects a chassis component having a depth that fits a data center and then installs tray components into the chassis component by selecting the tray component depths to fit in that of the chassis component. The tray component supports different processing components depending upon the selected depth so that information handling system features are adapted to chassis depth while using a common infrastructure component.

Abstract: A system and method are disclosed for using directory services to manage resources in a virtual execution environment. A directory repository is populated with resource, administration, roles, policy, and service-level agreement (SLA) objects. A service request is received by a virtual machine manager (VMM) administrator, which determines its requirements. The directory repository is queried with a directory service to identify available resources to fulfill the service request. The service request is routed to the VMM of the virtual machine (VM) host comprising the available resources. If an active VM comprises the available resources, then its roles, policy, and SLA objects are retrieved from the directory repository. The objects are then used to respectively determine if the service request has sufficient authentication and authorizations, if the VM's configuration meets the service request's resource requirements, and if service-levels requirements can be maintained.

Abstract: A system and method are disclosed for the transcoding of data from a first format to a second format. A data format transcoder receives a request for data from a requester. The desired format of the requested data is determined. A descriptor file containing formatting information describing the requested format is loaded into the data format transcoder. The requested data is retrieved in its native format along with its corresponding common descriptor. The requested data is read in its native format, using the formatting information from its associated common descriptor. The data format transcoder then uses the formatting information in the common descriptor of the requested format to perform transcoding operations to convert the requested data from its native format into the requested format.
