What is the form factor and scalability of this switch?

It is a 1U rack-mountable SAN switch with Ports on Demand (PoD) for scaling from 8 to 24 ports in 8-port increments, including license and optics. This enables cost-effective growth without compromising Gen6 32Gb functionality.

What performance metrics does the SN3600B offer?

Delivers 768 Gbps end-to-end full duplex aggregate bandwidth with port-to-port latency under 900 nanoseconds using cut-through switching at 32 Gbps. ISL Trunking supports up to 256 Gbps (512 Gbps full duplex) per link.

Is the SN3600B suitable for all-flash storage?

Yes, it provides flash-ready Gen6 performance with low latency and high throughput for all-flash SANs, supporting high-density virtualization and cloud architectures with 24 x 32Gb SFP+ ports.

What airflow and monitoring features are included?

Supports only back-to-front (non port-side intake) airflow with real-time power monitoring. This enhances efficiency in dense racks and aids in managing energy usage for enterprise deployments.

Does it support backward compatibility?

Yes, 32Gb/s transceivers autonegotiate to 16/8Gb/s, and 16Gb/s to 16/8/4Gb/s, replacing three generations of FC switches while protecting investments in existing infrastructure.

Product overview

The HPE SN3600B (SKU: R4G55B) is a B-series Fibre Channel Switch designed for enterprise SAN environments. It features 24 active ports with 8-port 16Gb Short Wave SFP+ transceivers, supporting 32Gb Fibre Channel speeds that autonegotiate to 16Gb, 8Gb, or 4Gb for backward compatibility. This rack-mountable 1U switch delivers 768 Gbps end-to-end full duplex aggregate bandwidth and port-to-port latency under 900 nanoseconds, ideal for high-density server virtualization, cloud architectures, and all-flash storage. Ports on Demand (PoD) enables scalable growth from 8 to 24 ports without compromising Gen6 functionality. Inter-Switch Link Trunking combines up to eight ports for 256 Gbps (512 Gbps full duplex) logical ISLs, ensuring high availability and load balancing. Real-time power monitoring and back-to-front airflow enhance operational efficiency in diverse Fibre Channel deployments, simplifying zoning and supporting F/E/M/D port types with FOS v8.1.0.
