LN-4248Y-6Z is a high port density switch with (25GbE/100GbE) suitable for TOR and Datacenters Application switches that builds upon 10/40Gbe models success.

With 48-Port x 25GbE and 6 uplink ports of 100GbE it is ideally suited for deployment at the server access layer in large enterprise data centers. These switches are also designed for deployment at the core layer of data centers at medium-size enterprises. With support for secure Infrastructure as a Service (IaaS) these devices meet the needs for higher-performance server connectivity, convergence of Ethernet,
storage and video traffic with capability to handle virtual environments, and ultra-low latency – all in a single device.

Main applications for LN-4248Y-6Z are: Enterprise, Campus Aggregation and Core, Data Center Aggregation and Core, Spine/Leaf Switches. Use of Intel C2538 CPU with SO-DIMM memory and mSATA flash expansion enables custom software configurations.

Programmable header architecture allows support of VXLAN, NVGRE and future possible VXLAN-GPE, Geneve and NSH encapsulation. With support for encapsulated traffic routing switch can serve as gateway between MPLS (VPLS, EVPN) and VXLAN domains, processing packets in single-pass. Switch supports two-step and one-step Precision Time Protocol (PTP), providing high-accuracy clock synchronization, required by data center applications, such as financial trading and time-based updates in SDN. Cascading is available with previous generations of switches and Marvell PIPE units that support Marvell eDSA/DSA tagging.
