Abstract: Methods, apparatus, and systems, for interfacing one or more storage devices with a plurality of bridge chips. An apparatus may include a memory, a communication bus coupled to a device, and a processor communicatively coupled to the communication bus and the memory. The processor may be configured to implement storage traffic between a storage device and a central processor via a first storage port of a first bridge chip of a plurality of bridge chips. The processor may be further configured to multiplex, by the first bridge chip, the storage traffic to at least one bridge chip of the plurality of bridge chips, and distribute data across the plurality of bridge chips to produce a data distribution enabling each of the bridge chips to communicate with each other.

Abstract: The present disclosure relates to techniques for providing data redundancy after reducing memory writes. In one example implementation according to aspects of the present disclosure, a storage controller receives a storage command for providing data redundancy in accordance with a first data redundancy scheme. The storage controller then translates the storage command for providing the data redundancy in accordance with a second data redundancy scheme.

Abstract: A storage subsystem receives writes via a storage subsystem interface and reduces a number of the writes. Data associated with the reduced number of writes is stored in storage devices of a single drive. Computed redundancy information is stored in the storage devices. A data redundancy scheme is implemented via a disk controller that is enabled to operate without a loss of data in the presence of at least a single failure of any of the storage devices.

Abstract: The present disclosure relates to examples of reducing memory write operations using coalescing memory buffers. In one example implementation according to aspects of the present disclosure, a method comprises computing a difference between a current state of data of at least one block of a storage device to which data is to be written and a state that would result from a write operation. The method further comprises populating at least one coalescing memory buffer with difference information associated with the difference and to be used to update an associated block of the storage device.
