HPE Storage Fibre Channel Switch B-series SN3700B
As data volumes explode and applications demand instant response times, legacy storage networks can become a critical bottleneck. To stay competitive, organizations need a storage area network (SAN) that is not only fast and reliable but also intelligent and adaptive. The HPE Storage Fibre Channel Switch B-series SN3700B is engineered to meet these modern challenges head-on, delivering an affordable, high-performance foundation for flash, NVMe storage, and hyper-scale virtualized environments.
Built on cutting-edge Gen7 64Gb Fibre Channel technology, the SN3700B provides the bandwidth and ultra-low latency required to eliminate I/O bottlenecks and accelerate data access. It offers a simple, scalable, and always-on infrastructure designed for small to mid-sized organizations, enabling them to harness enterprise-class capabilities without the associated complexity or cost. This switch is the building block for a modern, autonomous SAN that can keep pace with your evolving business requirements.
The HPE SN3700B moves beyond simple data transport to create a truly intelligent storage network. It is designed to enable a self-learning, self-optimizing, and self-healing autonomous SAN. By integrating powerful analytics and advanced automation, the switch can proactively monitor data flows, identify potential issues, and adapt to changing workloads, ensuring resilient, 24x7 operations with minimal manual intervention.
This switch delivers a significant performance leap, with 64Gbps line-rate speed and an aggregate throughput of 1.536 Tbps. Its switching latency is an exceptionally low 460 ns, making it a perfect match for latency-sensitive solid-state and NVMe storage architectures. With a flexible Port-on-Demand (PoD) model, you can start with just 8 active ports and scale seamlessly to 24 as your needs grow, protecting your initial investment and providing a clear path for expansion.

Q: What is the main performance advantage of the Gen7 64Gb Fibre Channel in the SN3700B?
A: The Gen7 64Gb Fibre Channel technology provides double the speed of the previous 32Gb generation. This results in an aggregate throughput of 1.536 Tbps and an extremely low switching latency of 460 ns, which is critical for accelerating performance in modern flash and NVMe-based storage environments.
Q: What does 'autonomous SAN' mean in the context of this switch?
A: An autonomous SAN, as enabled by the SN3700B, refers to a storage network with self-learning, self-optimizing, and self-healing capabilities. It uses integrated analytics and automation to monitor the network, predict potential issues, and adapt to changing workloads, which increases reliability and significantly reduces manual administration.
Q: How does the Port-on-Demand (PoD) scalability work?
A: The HPE SN3700B switch is physically equipped with 24 ports. It can be purchased with a base configuration of 8 active ports. As your connectivity needs grow, you can purchase Port-on-Demand software license kits to activate additional ports in increments, allowing you to scale up to the full 24 ports without needing to replace the hardware.
Q: Is the SN3700B suitable for NVMe storage?
A: Yes, it is explicitly optimized for NVMe and solid-state storage. Its ultra-low latency (460 ns) and high throughput are designed to eliminate network bottlenecks, allowing organizations to realize the full performance benefits of NVMe-oF (NVMe over Fibre Channel) storage arrays.
Q: Can I use both 32Gb and 64Gb devices with this switch?
A: Yes. The switch ports are flexible and can operate with either 32Gb SFP28 or 64Gb SFP56 transceivers, providing backward compatibility with existing 32Gb infrastructure while enabling a seamless path to upgrade to 64Gb speeds.
Q: What is the form factor of the HPE SN3700B?
A: The switch has a compact 1U rack-mountable form factor, making it an efficient choice for saving valuable space in data center racks.
Q: How can I determine if the 8-port base model is sufficient or if I need more ports?
A: The ideal number of ports depends on your current device count and projected growth. Nexus ITX can help you analyze your server and storage connectivity requirements, plan for future expansion, and evaluate whether starting with the 8-port model and utilizing PoD upgrades is the most effective strategy for your organization.
