WS-C4900M Use Case

Data Center Top-of-Rack High-Density Aggregation

In a hyperscale data center, the Cisco WS-C4900M (4948) delivers 48 Gigabit Ethernet ports plus four 10Gb SFP+ uplinks in a 1RU chassis, consolidating server connections and simplifying cabling. Its non-blocking switching fabric and modular uplinks optimize east-west traffic flows, reducing latency by up to 30% and increasing rack consolidation efficiency. The result is scalable, high-performance aggregation that supports rapid VM provisioning and seamless capacity expansion.

Enterprise Campus Distribution for Converged Voice, Video and Data

As a distribution-layer switch in a large corporate campus, the Cisco 4948 WS-C4900M unifies Gigabit Ethernet connectivity for voice, video surveillance and desktop data over a single, resilient platform. Advanced QoS, Intelligent Resilient Fabric (IRF) and IEEE 802.1Q VLAN segmentation ensure predictable service-level performance and secure traffic isolation. The outcome is simplified network architecture, 99.999% availability and streamlined operations for converged enterprise applications.

Low-Latency Backbone for Financial Trading and HPC Clusters

In demanding environments like high-frequency trading floors or HPC compute clusters, the WS-C4900M (Cisco 4948) provides sub-microsecond latency and jitter-free packet forwarding across 48 GbE ports. Its wire-speed throughput and deep buffer architecture maintain transactional integrity under burst loads, while redundant power supplies and hot-swappable fans guarantee nonstop operation. This yields deterministic performance, reduced transaction times and enhanced compute-to-network synchronization.
