The complete practical guide to architect storage networks for maximum efficiency, and to quickly troubleshoot congestion issues.
Data is the most important entity in a data center. In addition to being stored securely for the long term, data must be accessible to applications with low latency so that high performance can be maintained 24/7. To meet this performance goal of applications, the storage infrastructure services must be designed accordingly.
In Detecting, Troubleshooting, and Preventing Congestion in Storage Networks, leading Cisco experts take a practical approach to explaining the congestion handling mechanisms of the transport technologies like FC, FCoE, RoCE, and TCP. The authors share proven troubleshooting methodology developed through years of firsthand experience as well as analytical techniques for monitoring the storage fabrics and gaining predictive insights.
Through real-world experiences and case study examples, you'll learn what questions to ask, how to start planning, what exists today, what components still must evolve, and how to drive value in building custom applications in detecting congestion in large-scale storage networks.
- Optimize user experience with faster resolution of congestion in storage networks in production data centers
- Master congestion handling mechanisms in technologies like FC, FCoE, RoCE, and TCP
- Applicable to networks connected to all storage array types and vendors including Dell, HPE, IBM, NetApp, Hitachi
- Real-world case studies and troubleshooting methodology ensuring storage SLAs are consistently met
- Increase uptime with custom analytical tools for predicting and resolving congestion
- Boost storage infrastructure efficiency in a hybrid cloud model
- Save on employee training and reduce support ticket hassles with vendors
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.
