WS-C4948-10GE-S Use Case
Data Center Leaf-Spine Fabric for Virtualized Workloads
In a VMware ESXi cluster supporting 2,000+ VMs, the WS-C4948-10GE-S Cisco 4948 Switch acts as a leaf node, aggregating 48 Gigabit server uplinks and four 10GbE spine connections. This architecture delivers sub-microsecond latency, non-blocking 720 Gbps throughput, and seamless VM mobility—ensuring predictable performance during live migrations and peak I/O bursts.
Campus Aggregation Switch for Unified Communications and HD Video
An enterprise campus with 10 office buildings uses the WS-C4948-10GE-S Cisco 4948 Switch at each building’s telecom room to aggregate 48 edge access switches into two redundant 10GbE uplinks. Advanced QoS and jumbo-frame support guarantee jitter-free HD videoconferencing and VoIP traffic, improving collaboration uptime by 99.99% and simplifying network operations with Cisco IOS-XE automation.
High-Performance Computing Interconnect for Data-Intensive Research
A university HPC cluster running genomics analysis leverages the WS-C4948-10GE-S Cisco 4948 Switch as its core interconnect. With 720 Gbps non-blocking bandwidth and low-latency forwarding, large data sets move between 100+ compute nodes at line rate. This reduces job completion times by 40% and accelerates time-to-insight for critical scientific workloads.
