JE073B Use Case
Enterprise SAN Fabric for Virtualized Data Centers
In a global enterprise running VMware and Hyper-V clusters, the JE073B-HPE 5120 16G SI Switch is deployed as top-of-rack SAN aggregation to deliver 16 Gb/s Fibre Channel connectivity. This configuration ensures low-latency, high-availability storage access, simplifies zoning and management, and boosts application performance and VM density across multi-site data centers.
Disaster Recovery Replication Over Metro Fibre Channel
A financial services firm uses JE073B-HPE 5120 16G SI Switches at primary and backup sites to create a resilient metro-area SAN fabric. Leveraging native Fibre Channel IP (FCIP) tunnels and multipath failover, the solution achieves sub-1 ms latency and sustained 16 Gb/s throughput. The outcome: reduced RPO/RTO, seamless data mirroring, and compliance with stringent uptime SLAs.
High-Performance Computing Storage Backbone
In an HPC research lab, the JE073B-HPE 5120 16G SI Switch forms the backbone of a parallel file system connecting GPU compute nodes to high-throughput storage arrays. The 16 Gb/s Fibre Channel fabric delivers deterministic I/O and low jitter for simulation workloads. Benefit: accelerated data analysis, streamlined management with intuitive zoning, and scalable expansion for future compute clusters.
