Abstract:
Provided are a system, memory controller, and method for using counters and a table to protect data in a storage device. Upon initiating operations to modify a file in the storage device, a storage write counter is incremented in response to initiating the operations to modify the file. In response to incrementing the storage write counter, write table operations are initiated including setting a table write counter to a storage write counter and setting a table commit counter to the storage commit counter plus a value. The operation to modify the file in response to completing the write table operations. The system commit counter is incremented by the value in response to completing the operation to modify the file.
Abstract:
Provided is a technique for power and performance management of one or more storage devices. With a power and performance management agent, a power change notification identifying a power set point is received and a power state of at least one storage device is adjusted.
Abstract:
Electronic assemblies including coreless substrates and their manufacture using electrolytic plating, are described. One method includes providing a core comprising a metal, and forming a dielectric material on the core. The method also includes forming vias in the dielectric material, the vias positioned to expose metal regions. The method also performing an electrolytic plating of metal into the vias and on the metal regions, wherein the core is electrically coupled to a power supply during the electrolytic plating of metal into the vias and delivers current to the metal regions. The method also includes removing the metal core after the electrolytic plating of metal into the vias. Other embodiments are described and claimed.
Abstract:
Provided are techniques for processing a data segment by stripping a header from a transport layer segment, performing protocol data unit detection to determine data for a protocol segment that is part of the transport layer segment data, and performing marker validation and stripping. Also provided are techniques for processing a data segment in which a header portion of a protocol data unit is received. A number of bytes of data to be stored in an application space is determined using the received header portion. Also, a next header portion of a next protocol data unit is determined using the received header portion. Then, a peek command is issued to obtain the next header portion. Additionally provided are techniques for performing cyclic redundancy checks using a stored partial cyclic redundancy check digest and residual data.
Abstract:
Provided are an apparatus and method for processing sequential writes to a block group of physical blocks in a memory device. Sequential write data for a plurality of consecutive logical addresses is received and a determination is made of consecutive physical blocks comprising a block group. Each of the physical blocks has data for a plurality of the consecutive logical addresses. The sequential write data is written to consecutive physical data locations having data for the determined consecutive physical blocks of the block group. The block group metadata for the block group is updated.
Abstract:
A method and system to improve the performance and/or reliability of a solid-state drive (SSD). In one embodiment of the invention, the SSD has logic compress a block of data to be stored in the SSD. If it is not possible to compress the block of data below the threshold, the SSD stores the block of data without any compression. If it is possible to compress the block of data below the threshold, the SSD compresses the block of data and stores the compressed data in the SSD. In one embodiment of the invention, the SSD has logic to dynamically adjust or select the strength of the error correcting code of the data that is stored in the SSD. In another embodiment of the invention, the SSD has logic to provide intra-page XOR protection of the data in the page.
Abstract:
Provided is a method, system, and program for coordinating access to memory locations for hardware transactional memory transactions and software transactional memory transactions. A hardware transaction executing in hardware transactional memory initiates a request to access a memory location. A fault is returned to the hardware transaction request in response to an operation by one software transaction executing in a software transactional memory.
