Latency reduction in network data transfer operations
First Claim
1. A method, comprising:
- performing, at an initiator driver in a computing system, a first write operation to a target system wherein the write operation transfers a block of data from the computing system to the target, the write operation including sending a plurality of data packets which together form the block of data, wherein some or all of the data packets are sent only after the driver receives a ready to transfer command from the target;
receiving, at the initiator driver, a request for a second write operation from the computing system before all the data packets for the first write operation have been sent, and sending a write command to the target in-between sending two of the data packets so that the second write command is sent before completion of the first write operation.

Abstract
Apparatus, method and computer readable medium are provided for data transfer wherein an initiator driver in a computing system performs a first write operation to a target system wherein the write operation transfers a block of data from the computing system to the target, the write operation including sending a plurality of data packets which together form the block of data, wherein some or all of the data packets are sent only after the driver receives a ready to transfer command from the target. The initiator driver receives a request for a second write operation from the computing system before all the data packets for the first write operation have been sent, and sending a write command to the target in-between sending two of the data packets so that the second write command is sent before completion of the first write operation. According to another aspect, the initiator driver receives a request from the computing system to perform two or more write operations prior to initiating the first write operation and while no other write operations are being performed, and wherein the initiator system sends at least two write commands, one for each request for a write operation, to the target system prior to receiving a ready to transfer command from the target system.

3. Apparatus, comprising:
-
an initiator driver in a computing system including a first software component that performs a first write operation to a target system wherein the write operation transfers a block of data from the computing system to the target, the write operation including sending a plurality of data packets which together form the block of data, wherein some or all of the data packets are sent only after the driver receives a ready to transfer command from the target; the initiator driver including a second software component receiving a request for a second write operation from the computing system before all the data packets for the first write operation have been sent, and sending a write command to the target in-between sending two of the data packets so that the second write command is sent before completion of the first write operation. - View Dependent Claims (4)
