A flexible storage system. A storage motherboard accommodates, on a suitable connector, a storage adapter circuit that provides protocol translation between a host bus interface and a storage interface, and that provides routing, to accommodate a plurality of mass storage devices that may be connected to the storage adapter circuit through the storage motherboard. The storage adapter circuit may be replaced with a circuit supporting a different host interface or a different storage interface.

Multi-protocol IO infrastructure for a flexible storage platform

A method of operating a computer network system configured with disaggregated inputs/outputs. This system can be configured in a leaf-spine architecture and include a router coupled to a network source, a plurality of core switches coupled to the router, a plurality of aggregator switches coupled to each of the plurality of core switches, and a plurality of rack modules coupled to each of the plurality of aggregator switches. Each of rack modules can include an I/O appliance with a downstream aggregator module, a plurality of server devices each with PCIe interfaces, and an upstream aggregator module that aggregates each of the PCIe interfaces. A high-speed link can be configured between the downstream and upstream aggregator modules via aggregation of many serial lanes to provide reliable high speed bit stream transport over long distances, which allows for better utilization of resources and scalability of memory capacity independent of the server count.

Multi-protocol I/O infrastructure for a flexible storage platform

A system and method for managing garbage collection in Solid State Drives (SSDs) in a Redundant Array of Independent Disks (RAID) configuration, using a RAID controller is described. A control logic can control read and write requests for the SSDs in the RAID configuration. A selection logic can select an SSD for garbage collection. Setup logic can instruct the selected SSD to enter a garbage collection setup phase. An execute logic can instruct the selected SSD to enter and exit the garbage collection execute phase.

Display data used in display frame generation are compressed for efficient storage in a local memory within a graphics processing unit. The compression technique used is difference encoding and before performing difference encoding, display data in RGB format are converted into YCbCr format. Since the component values of adjacent pixels in YCbCr format typically vary less than the component values of the same adjacent pixels in RGB format, converting the display data to YCbCr format before performing difference encoding improves the compression efficiency.
