OceanStor SNS2624/SNS3664/SNS3696E Switches

Huawei OceanStor SNS2624/SNS3664/SNS3696E Switches are the purpose-built network infrastructure for mission-critical storage.

Using Gen 6 Fiber Channel, Fabric Vision technology deliver unmatched 32 Gbit/s performance, increased scalability, and operational stability to ensure hyper-scale virtualization, larger cloud infrastructures, and growing flash-based storage environments.

Purpose-built for enterprise deployments, a cost-effective choice for network expansion

  • High performance: Purpose-built for enterprise deployment. Power up from 16 Gbit/s to 32 Gbit/s
  • Expand on demand: Provide “pay-as-you-grow” flexibility and Ports-on-Demand (PoD) capabilities for port expansion
  • Intelligent and flexible: Provide affordable storage switches that redefine simplicity and flexibility. Deliver proactive, non-intrusive, real-time monitoring and alerting of storage IO health and performance with IO Insight
