Modern Data Center Demands and the Case for NVMe/TCP with Hitachi VSP and Cisco UCS

By Arvin Jami posted 23 days ago
Be the first person to like this.
In today’s enterprise and cloud infrastructures, achieving high throughput, low latency, and efficient scale-out is increasingly critical. Storage bottlenecks are often the culprit—especially in virtualization, AI/ML, analytics, and database workloads where I/O demands are intense. Traditional SANs (Fibre Channel or iSCSI) have served well, but newer protocols such as NVMe over Fabrics (NVMe-oF) promise lower latency, improved parallelism, and better use of NVMe SSDs/disaggregated storage. Among NVMe-oF transports, NVMe/TCP provides an attractive trade-off: leveraging existing TCP/IP networks rather than requiring specialized fabrics such as RDMA (RoCE). ...

Best Practices for Configuring NVMe-TCP on ESXi Hosts with Hitachi VSP One Block 20 Series Storage

By Payel Sarkar posted 09-12-2025
3 people like this.
Introduction: NVMe over TCP (NVMe/TCP) is becoming increasingly popular as it delivers high performance and scalability over standard Ethernet networks. When deployed with VMware ESXi and Hitachi VSP One Block 20 Series storage, it can support critical workloads efficiently. However, in ESXi 8.0U3f and earlier builds, default configurations may lead to performance delays. Additionally, presenting many namespaces across multiple subsystems can result in excessive NVMe controllers, straining ESXi resources during outage recovery. This blog explains and highlights the issues, root causes, and best practice recommendations to optimize NVMe/TCP with Hitachi ...
