HPE SN6650B Fibre Channel Switch

Designed for mission‑critical data centers, the HPE SN6650B Fibre Channel Switch delivers flash‑ready performance, ultra‑low latency, and scalable SAN fabric capabilities that power intense storage workloads. As a member of the HPE B‑series, the SN6650B is built to accelerate database, virtualization, and backup operations while maintaining robust reliability and straightforward management. With a non‑blocking, cut‑through architecture and substantial bandwidth, this switch helps storage networks meet today’s demands and scale for tomorrow’s growth.

• Flash‑Ready performance for storage‑intensive workloads: The SN6650B provides up to 4 Tbps of total bandwidth with exceptionally low latency, measured at under 780 nanoseconds including FEC. This cut‑through switching approach minimizes buffering delays, delivering near‑line‑rate performance across the fabric. For enterprises running databases, virtualized environments, large backups, and high‑demand file services, this means faster data access, quicker failovers, and smoother operational workflows. The combination of high bandwidth and low latency helps reduce queueing, enabling more consistent response times even in dense, multi‑host SAN deployments.
• Exceptional IOPS and frame handling for peak workloads: With support for up to 200 million IOPS and a frame‑switch capacity reaching hundreds of millions of frames, the SN6650B is engineered to handle sudden bursts and long‑running storage tasks with ease. This capability translates to sustained performance under concurrency, improved queue depth handling, and reliable throughput for mixed workloads, including highly transactional databases, virtual machine migrations, and large sequential data transfers. The switch’s architecture is designed to minimize fragmentation and maintain steady throughput as fabric traffic grows.
• Reliability, availability, and data integrity built in: The HPE SN6650B is designed to deliver consistent performance under load while providing robust resilience features common to enterprise SAN fabrics. Cut‑through switching reduces latency and buffering, while built‑in fault tolerance and fault management practices help prevent single points of failure from impacting data paths. Sophisticated error detection and adaptive retry mechanisms contribute to more stable, predictable fabric behavior during routine maintenance windows or firmware updates, enabling more reliable backups, restores, and replication tasks.
• Seamless integration and comprehensive management: This switch is engineered to integrate smoothly with existing SAN fabrics and storage ecosystems, offering compatibility with standard Fibre Channel protocols and common storage array configurations. Centralized management through familiar CLI and GUI interfaces, along with compatibility with HPE management tools and monitoring platforms, helps administrators provision zoning, mask lun configurations, and monitor port statistics efficiently. The SN6650B supports streamlined fabric provisioning, QoS for traffic classes, and simplified firmware updates to keep the fabric current without disruptive downtime.
• Future‑ready scalability and flexible deployment: The SN6650B is built to scale with growing data center needs, supporting expansion within the HPE B‑series family and integration into larger SAN topologies. It enables organizations to consolidate storage networks, optimize resource utilization, and plan capacity with a forward‑looking approach to backup windows, archival storage, and disaster recovery. With resilient hardware, scalable fabric options, and straightforward lifecycle management, this switch supports long‑term investment protection while delivering sustained performance gains over time.
