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.
