QW937A Use Case
Mission-Critical Data Center SAN Consolidation
In a large enterprise data center running Oracle and SAP databases, the QW937A-SN3000B 24/12 16Gb FC Switch consolidates multiple storage arrays into a unified Fibre Channel SAN. This deployment reduces port sprawl by 30%, ensures sub-microsecond latency, and delivers uninterrupted access for 24x7 operations, boosting overall storage efficiency and SLA compliance.
High-Performance Virtualization for VDI and Cloud
A global financial firm uses VMware vSphere with NVIDIA GPU-accelerated workloads to power VDI and private cloud services. Integrating the QW937A-SN3000B 16Gb FC Switch provides low-latency, high-throughput SAN connectivity that scales to 2,000 virtual desktops. The result is 40% faster I/O performance, predictable user experience, and simplified storage management through VSAN and NPIV support.
Disaster Recovery and Synchronous Replication
A healthcare network implements synchronous replication between primary and remote sites for patient record databases. The QW937A-SN3000B 24/12 16Gb FC Switch enables 16 Gbps encrypted FC tunnels, maintaining RPO of zero and RTO under 30 seconds. This solution ensures HIPAA-compliant data continuity, automated failover, and dramatically lowers the risk of data loss during outages.
