    Abstract: Methods and systems provided herein involve extracting an input/output (I/O) operation from a packet received over an I/O pipeline, the I/O operation comprising either a read request to read data from at least one storage device or a write request to write data to the at least one storage device; determining that an address associated with the I/O operation exists in a lookup table that is provided for thin provisioning of the at least one storage device; performing one or more RAID calculations associated with the at least one storage device based on the address and the I/O operation; and accessing the at least one storage device to perform the I/O operation based on the one or more RAID calculations; and second processing component configured to carry out a second set of operations that occur when the address associated with the I/O operation does not exist in the lookup table.

    Abstract: Methods, systems, and devices for message signaled interrupt (MSI-X) tunneling on a host device exposed by a bridge connection are described. A device may receive data and a first interrupt signal from a remote destination over a network protocol. The device may receive the data and/or the first interrupt signal over the bridge connection, via a tunneled communication from the remote destination. The device may generate a second interrupt signal based on the first interrupt signal and a local interrupt configuration provided by a system bus driver of the device. The device may inject the data and the second interrupt signal over the system bus. Injecting the data and injecting the second interrupt signal may include ensuring the data is made available to the system bus driver, prior to the interrupt handler receiving the second interrupt signal.

    Abstract: API in conjunction with a bridge chip and first and second hosts having first and second memories respectively. The bridge chip connects the memories. The API comprises key identifier registration functionality to register a key identifier for each of plural computer processes performed by the first host, thereby to define plural key identifiers; and/or access control functionality to provide at least computer process P1 performed by the first host with access, typically via the bridge chip, to at least local memory buffer M2 residing in the second memory, typically after the access control functionality first validates that process P1 has a key identifier which has been registered, e.g., via the key identifier registration functionality. Typically, the access control functionality also prevents at least computer process P2, performed by the first host, which has not registered a key identifier, from accessing local memory buffer M2, e.g., via the bridge chip.

    Abstract: Systems and methods herein are for one or more processing units of a subnet manger (SM) to communicate configuration information with at least one subnet management agent (SMA) that is associated with at least one switch and with a host machine, the configuration information to enable the at least one switch to configure a forwarding table based in part on a mapping of at least one virtual network address to physical network addresses of two or more physical ports of the host machine, and the configuration information to enable the host machine to communicate with other host machines using the at least one switch and the at least one virtual network address.

    Abstract: A method for data storage includes provisioning, in a cluster of computers, including at least first and second computers, which are connected to a packet data network, a range of RAM on the second computer for use by the first computer. Blocks of data are stored in the provisioned range for use by programs running on the first computer. Upon incurring a page fault on the first computer in response to a request for a page of virtual memory by a program running on the first computer, a block swap request is directed to the NIC of the first computer with respect to the requested page. In response to the block swap request, an RDMA read request is initiated by the NIC via the network to the NIC of the second computer, to retrieve the requested page from the provisioned range, so as to resolve the page fault.
