Should you use InfiniBand or RDMA over Converged Ethernet as an interconnect? We discuss each technology's effect on performance features such as latency, IOPS and throughput
"Storage sharing has been an important aspect of storage cost control and performance optimization for more than two decades," writes Marc Staimer, in SearchStorage.
"The goal has been to squeeze the best performance for the lowest cost out of the shared storage.
"There are essentially four types of shared storage -- block, file, object and parallel file -- commonly found in high-performance computing (HPC) environments. And while each approach must solve multiple storage bottlenecks to achieve its optimal performance, this article focuses on issues related to external interconnect performance to client endpoints..."
