Technologies for accelerating data writes include a managed node that includes a network interface controller that includes a power loss protected buffer and non-volatile memory. The managed node is to receive, through the network interface controller, a write request from a remote device. The write request includes a data block. The managed node is also to write the data block to the power loss protected buffer of the network interface controller, and send, in response to receipt of the data block and prior to a write of the data block to the non-volatile memory, an acknowledgement to the remote device. The acknowledgement is indicative of a successful write of the data block to the non-volatile memory. The managed node is also to write, after the acknowledgement has been sent, the data block from the power loss protected buffer to the non-volatile memory. Other embodiments are also described and claimed.
