Modern storage systems are required to scale to large storage capacities and I/O throughput in a cost effective manner. For this reason, they are increasingly being built out of commodity components, mainly PCs equipped with large numbers of disks and interconnected of high-performance system area networks. A main issue in these efforts is to achieve high I/O throughput over commodity, low-cost system area networks and commodity operating systems.In this work, we examine in detail the performance of remote block-level storage I/O over commodity, RDMA-capable network interfaces and networks. We examine the support that is required from the network interface for achieving high throughput. We also examine in detail the overheads associated in kernel-level protocols for networked storage access. We find that base system performance is limited by (a) interrupt cost, (b) request size, and (c) protocol message size. We examine the impact of techniques to alleviate these factors and find that our techniques combined can improve throughput by up to 100% over a simpler unoptimized configuration. Our current prototype is able to achieve a throughput of about 200 MBytes/s over a network that is capable of delivering about 500 MBytes/s. We identify major limiting factors, mostly at the I/O target-side.
