Detecting, Troubleshooting, and Preventing Congestion in Storage Networks
by Paresh Gupta, Edward Mazurek
Foreword
Storage infrastructure has changed considerably in the past few years due to the adoption of all-flash storage through technologies like NVMe and NVMe over Fabrics (NVMe-oF), which have made storage devices even faster. Today, performance at millions of input/output per second (IOPS), response times in microseconds, and throughput of hundreds of gigabytes per second are the new norm. Together with demanding applications for AI/ML use cases, 5G connectivity, and business-critical transactional workloads, this ultra-fast storage can transfer huge amounts of data with requirements for much lower response times.
These realities are stress-testing existing storage networks running older and lower-performance technologies such as rotational ...
