The described technology is generally directed towards accelerating data handling in a cloud data storage system by using smart network interface cards (SmartNICs) at the nodes. Instead of copying data to kernel space, many input/output (I/O) operations can be handled primarily by the SmartNIC, using the SmartNIC's memory. For example, mirrored data writes can be sent directly from the SmartNIC's memory associated with the node handling the write to other nodes, without first copying the data to kernel space. Object reads can be handled at a node by having segments of the object queued, in order, in the node's associated SmartNIC's memory, and sent to a requesting client without having to be copied to the handling node's kernel space, unless low memory conditions exist in the SmartNIC's memory.
