Gen 7 Fiber Channel infrastructure unleashes the performance of NVMe workloads with reduced latency and increased bandwidth. The FS8720 switch delivers unmatched 64 Gbps performance and industry-leading port density and provides advanced modules that support data growth, demanding workloads, and data center consolidation. With a 50% latency reduction compared to its predecessor, the FS8720 enables maximum storage performance of NVMe drives. In addition, it combines powerful analytics and advanced automation features to maximize performance and ensure reliability, providing a solid foundation for building autonomous SANs.

Key Features
On-demand scalability

FS8720 features exceptional scalability among 1U 64-port switches. Enterprises can scale from 24 ports to 64 SFP+ ports in an efficient 1U form factor that delivers industry-leading port density and space utilization.

Each SFP+ port supports a Fiber Channel speed of 64/32/16/8 Gbps.

Flash ready

Gen 7 Fiber Channel delivers advanced 64 Gbps performance, full-duplex operation mode, and a total bandwidth of up to 3.5 Tbps to redefine application performance limits and release the full potential of flash storage.

Supports NVMe over Fiber Channel, allowing enterprises to seamlessly integrate Gen 7 Fiber Channel networks and next-generation flash storage systems, without disruptive elimination and replacement.

Autonomous SAN

Adopts Fabric Vision technology to provide a robust analytics architecture that delivers autonomous SAN technology through self-learning, self-optimizing, and self-healing capabilities.

The Fabric Vision technology is a collection of features that leverage comprehensive data collection capabilities with powerful analytics to quickly understand the health and performance of the environment and identify any potential impacts or trending problems.
