Cisco Nexus 56128P 2RU Chassis, 48x10G SFP, 4x40G QSFP | Data Center — CON-SSSNT-NCS2K9SF

Consolidate access and aggregation traffic into a compact 2RU platform designed for dense data center fabrics. The Cisco Nexus 56128P chassis provides 48 x 10G SFP ports and 4 x 40G QSFP uplinks, giving infrastructure teams the port mix needed to attach servers, storage, and adjacent switching layers without overcommitting rack space. This chassis is a strong fit when port density, predictable uplink capacity, and operational consistency matter more than chasing lower-cost edge hardware. The 10G SFP footprint supports high-volume east-west traffic patterns, while the 40G QSFP uplinks provide the backbone bandwidth needed to keep oversubscription in check as workloads grow. In practice, that means fewer chassis swaps, cleaner cabling, and a better path for standardizing on a fabric architecture that can absorb expansion. For teams planning around long service windows and controlled refresh cycles, the 56128P offers the kind of physical density and interface balance that justifies its place in a production network. It is built for environments where downtime is expensive and switch selection has to align with both current throughput and future topology planning. Ideal For Data center leaf or aggregation switching High-density server connectivity in virtualized clusters Storage and compute fabric attachment Network refreshes requiring compact 10G access with 40G uplinks Why This Product 1 Higher port density than typical access switches 2 40G uplinks support aggregation-layer throughput 3 2RU footprint preserves rack space 4 Better fit for fabric designs than edge-only switches
