Abstract: Technologies for eliminating duplicate data within a storage system. De-duplication may be performed done at physical chunk level, where the data is not copied or moved to different location. A logical mapping is modified using a thin de-duplication kernel module that resides between a distributed volume manager (DVM) and a logical disk (LD). De-duplication is achieved by changing pointers in the mapping to land at a physical location. De-duplication is performed as post-process feature where duplicates are indentified and the duplicates are marked in the mapping table, thereby claiming free space through de-duplication. Block-level de-duplication in accordance with the above can co-exist with existing storage architectures for thin provisioning and snapshot management.

Abstract: A virtual disk carousel is provided that is capable of creating disk images from optical disks and storing the disk images. The virtual disk carousel includes a bridge device configured to expose disk images stored at the virtual disk carousel to a computer by way of a standard storage device.

The bridge device might also include a display and user input controls for managing the operation of the bridge device. The virtual disk carousel might also provide a user interface for managing the disk images, selecting a disk image to be exposed to the computer, and for performing other functions.

Abstract: An aspect relates to fail safe flashing techniques for a management device of a computer system. A non-volatile memory of the management device stores a current firmware, an actual critical information and a backup critical information, which is rewritable in a booting mode and read-only in a flash mode. A flasher module is launched to operate the management device in the flash mode. The actual critical information is copied to a volatile memory and erased in the non-volatile memory. A replacement firmware is used to upgrade the current firmware. The actual critical information is mixed and matched with a new critical information. A user input is requested to write the mixed and matched critical information back to the non-volatile memory as the actual critical information. When the user input is not received after a first predetermined time period, the mixed and matched critical information is automatically written back.

Abstract: Certain aspects direct to data transfer between a baseboard management controller (BMC) and a host computer. When the BMC is connected to the host computer via a universal serial bus (USB) interface, the BMC sends USB descriptors to the host computer such that the host computer recognizes the BMC as a specific human interface device (HID) device based on the USB descriptors. To transfer data to the host computer, the BMC converts the data to an Intelligent Platform Management Interface (IPMI) message, and generates a USB HID report containing the IPMI message as the report data. The BMC then sends the USB HID report to the host computer through the USB interface. When the BMC receives a USB HID report from the host computer, the BMC retrieves the report data, which is an IPMI message, from the USB HID report, and process the IPMI message to obtain the data.
