    Abstract: Apparatus, method and system for supporting Remote Direct Memory Access (RDMA) Read V2 Request and Response messages using the Internet Wide Area RDMA Protocol (iWARP). iWARP logic in an RDMA Network Interface Controller (RNIC) is configured to generate a new RDMA Read V2 Request message and generate a new RDMA Read V2 Response message in response to a received RDMA Read V2 Request message, and send the messages to an RDMA remote peer using iWARP implemented over an Ethernet network. The iWARP logic is further configured to process RDMA Read V2 Response messages received from the RDMA remote peer, and to write data contained in the messages to appropriate locations using DMA transfers from buffers on the RNIC into system memory. In addition, the new semantics removes the need for extra operations to grant and revoke remote access rights.

    Abstract translation: 使用互联网广域RDMA协议（iWARP）支持远程直接存储器访问（RDMA）读取V2请求和响应消息的装置，方法和系统。 RDMA网络接口控制器（RNIC）中的iWARP逻辑被配置为生成新的RDMA读取V2请求消息，并响应于接收的RDMA读取V2请求消息生成新的RDMA读取V2响应消息，并将消息发送到RDMA远程 通过以太网网络实现的iWARP对等体。 iWARP逻辑还被配置为处理从RDMA远程对等体接收的RDMA读取V2响应消息，并且使用从RNIC上的缓冲器的DMA传送到包含在系统存储器中的DMA传输将包含在消息中的数据写入适当的位置。 另外，新的语义消除了额外的操作来授予和撤销远程访问权限的需要。

    Abstract: Apparatus, methods and systems for supporting Send with Immediate Data messages using Remote Direct Memory Access (RDMA) and the Internet Wide Area RDMA Protocol (iWARP). iWARP logic in an RDMA Network Interface Controller (RNIC) is configured to generate different types of Send with Immediate Data messages, each including a header with a unique RDMA opcode identifying the type of Send with Immediate Data message, and send the message to an RDMA remote peer using iWARP implemented over an Ethernet network. The iWARP logic is further configured to process the Send with Immediate Data messages received from the RDMA remote peer. The Send with Immediate Data messages include a Send with Immediate Data message, a Send with Invalidate and Immediate Data message, a Send with Solicited Event (SE) and Immediate Data message, and a Send with Invalidate and SE and Immediate Data message.

    Abstract translation: 使用远程直接内存访问（RDMA）和互联网广域RDMA协议（iWARP）支持使用即时数据消息发送的设备，方法和系统。 RDMA网络接口控制器（RNIC）中的iWARP逻辑被配置为生成具有即时数据消息的不同类型的发送，每个消息包括标识具有立即数据消息发送类型的唯一RDMA操作码的报头，并将消息发送到RDMA 使用通过以太网实现的iWARP的远程对等体。 iWARP逻辑还被配置为处理从RDMA远程对等体接收的立即发送数据消息。 使用即时数据发送消息包括发送立即数据消息，发送无效和立即数据消息，发送请求事件（SE）和立即数据消息，以及发送无效和SE和立即数据消息。

    Abstract: An embodiment may include circuitry to facilitate, at least in part, a first network interface controller (NIC) in a client to be capable of accessing, via a second NIC in a server that is remote from the client and in a manner that is independent of an operating system environment in the server, at least one command interface of another controller of the server. The command interface may include at least one controller command queue. Such accessing may include writing at least one queue element to the at least one command queue to command the another controller to perform at least one operation associated with the another controller. The another controller may perform the at least one operation in response, at least in part, to the at least one queue element. Many alternatives, variations, and modifications are possible.

    Abstract: Generally, this disclosure relates to a method of flow control. The method may include determining a server load in response to a request from a client; selecting a type of credit based at least in part on server load; and sending a credit to the client based at least in part on server load, wherein server load corresponds to a utilization level of a server and wherein the credit corresponds to an amount of data that may be transferred between the server and the client and the credit is configured to decrease over time if the credit is unused by the client.
