N2 - Because of its high throughput, low CPU utilization, and direct data placement, RDMA (Remote Direct Memory Access) has been adopted for transport in a number of storage protocols, such as NFS and iSCSI. In this presentation, we provide a performance evaluation of RDMA-based NFS and iSCSI on Wide-Area Network (WAN). We show that these protocols, though benefit from RDMA on Local Area Network (LAN) and on WAN of short distance, are faced with a number of challenges to achieve good performance on long distance WAN. This is because of (a) the low performance of RDMA reads on WAN, (b) the small 4KB chunks used in NFS over RDMA, and(c)the lack of RDMA capability in handling discontinuous data. Our experimental results document the performance behavior of these RDMA-based storage protocols on WAN.
