An apparatus for applying database commands to one or more database tables includes a memory and a hardware-implemented pipeline. The hardware-implemented pipeline includes one or more table-processing circuits, and is configured to receive a stream of input records drawn from the one or more database tables, to parse first records, from among the input records, into a key and one or more fields other than the key, to store at least parts of the first records in the memory so as to be accessible using the key, and to apply a database command by matching at least parts of second records from among the input records to the at least parts of the first records stored in the memory, in accordance with the key.

A hardware-implemented file reader includes an interface, multiple hardware-implemented column readers and a hardware-implemented record reconstructor. The interface is configured to access a file including multiple records. The records store values in accordance with a nested structure that supports optional values and repeated values. The file is stored in a columnar format having multiple columns, each column storing (i) compressed values and (ii) corresponding compressed structure information that associates the values in the column to the nested structure of the records. Each column reader is configured to be assigned to a respective selected column, and to read and decompress both the values and the structure information from at least a portion of the selected column. The record reconstructor is configured to reconstruct one or more of the records from at least portions of the columns that are read by the column readers, and to output the reconstructed records.

Methods and systems for a virtual machine environment are provided. One method includes allocating a memory for storing a dirty pages data structure for tracking writes to a virtual machine memory by an adapter coupled to a computing device and shared by a plurality of virtual machines; initiating a tracking operation by the adapter or a virtual function driver to track writes to the virtual memory; providing access to the dirty pages data structure in response to a query command, while the adapter or the virtual function driver tracks writes to the virtual machine memory; and providing a number of dirty pages within the dirty pages data structure and a pointer the dirty pages data structure by the adapter or the virtual function driver.

A computing device having a host memory and a host processor for executing instructions out of the host memory; and a network interface card interfacing with the computing device are provided. When there is a cache hit for a read request, the network interface card processes the read request by obtaining data stored from one or both of the host memory and a storage device that the network interface card accesses without involving the host processor and when there are is a cache miss, then the read request is processed by the host processor.

Caching methods and systems using a network interface card

Methods and systems for efficiently processing input/output requests are provided. A network interface card (NIC) is coupled to a storage device via a peripheral link and accessible to a processor of a computing device executing instructions out of a memory device. The NIC is configured to receive a read/write request to read/write data; translate the read/write request to a storage device protocol used by the storage device coupled to the NIC; notify the storage device of the read/write request, without using the processor of the computing device, where the storage device reads/writes the data and notifies the NIC; and then the NIC prepares a response to the read/write request without having to use the processor of the computing device.

Methods and systems for accessing storage using a network interface card

Methods and systems for network communication are provided. One of the methods includes receiving an out of order packet at a requestor device that is communicably connected to a responder device; storing the out of order packet at an out of order buffer location; and sending a lossy reliable connection (LRC) packet to the responder device when selective acknowledgement (SACK) is supported between the requestor device and the responder device, with information regarding an updated sequence number in a LRC extended header (LRCETH) that indicates to the responder information regarding in-order packets that have been received by the requestor device.
