As storage networks mature, evolve, and must deliver ever-larger amounts of data, storage network congestion is becoming a critical problem. In this guide, a team of Cisco experts show how to detect, troubleshoot, and prevent congestion in any storage network, no matter whose storage arrays it uses. Writing for every IT professional involved in delivering storage services, this guide takes a balanced approach, addressing both mature and emerging technologies, from conventional Fibre Channel to the latest all-flash arrays and NVMe over Fabrics (NVMe-oF) solutions. The authors thoroughly explain congestion handling mechanisms of networking technologies such as Fibre Channel, lossless Ethernet, and TCP, offering a proven troubleshooting methodology they''ve developed working with customers of all kinds, and best practices for making future congestion less likely. Their practical case studies show how to monitor storage fabrics and gain insights for anticipating, detecting, and resolving congestion in any large-scale storage network. This isn''t just general conceptual education: it''s a go-to reference packed with reliable solutions you can rely on whenever you''re encountering storage network congestion-or making plans to avoid it. It will help you improve user experience, increase ROI from external storage, increase uptime, simplify your hybrid cloud transition, and even reduce support and training costs.

Autorenporträt
Paresh Gupta, CCIE No. 36645, has almost two decades of experience in the computer industry. Currently, as a senior leader of Technical Marketing Engineering for Cisco, he drives the technical and market evolution of products, technologies, and solutions such as SAN Analytics, Nexus Dashboard, UCS, MDS, and Nexus switches. He has been testing and validating congestion in storage networks for many years. In his multiple roles, he has invented/patented many ideas, developed many features, and trained thousands of people in sales, partner, and customer communities. Paresh is the creator of the fullblown traffic monitoring apps for Cisco UCS Servers (UTM) and MDS switches (MTM). Hundreds of organizations use Pareshs apps in production around the world.   Edward Mazurek, CCIE No. 6448, has more than 40 years of experience in the computer networking industry. The first 18 were with IBM, supporting products such as Virtual Machine (VM) and VTAM. He has spent the last 22+ years with the Cisco TAC. As a principal engineer, he supports data center networking technologies, including storage-area networking, Fibre Channel, and FCoE in the MDS, UCS, and Nexus 5000, 6000, 7000, and 9000 series. He holds two CCIEsSNA/IP Integration (2000) and Storage Area Networking (SAN)and is presently a CCIE Emeritus. Ed has spearheaded the congestion-handling mechanisms on the Cisco MDS 9000 switches and Nexus 9000 switches. Based on his deep understanding, Ed developed an app that is being used by other Cisco engineers and continues to be in high demand by various partners. In addition to inventing multiple features on Cisco products, Ed holds multiple patents in the field of network congestion.
