QuantaMesh 3000 Series BMS T3048-LY2R

A Powerful Top-of-Rack Switch for Datacenter and Cloud Computing 

Datacenter networks are facing a major paradigm shift toward the disaggregation of software and hardware. This move, combined with the benets of software-dened networking (SDN) allows network administrators respond quickly to changing business requirements at a lower capital cost as well as reducing the network operations complexity.

QuantaMesh BMS products oer higher performance, increased availability, low latency and better serviceability. QuantaMesh T3048-LY2R supports 48 SFP+ (1/10GbE speed) and 4 QSFP+ (10/40GbE speed) ports in a compact 1U size. By leveraging merchant silicon chips, T3048-LY2R is a high performance high density Ethernet switch with an aordable price for the deployment of data center infrastructure. With ONIE (Open Network Installation Environment) pre-loaded on QuantaMesh BMS switches, it provides the exibility and allows choice of network operating system supported by ONIE installer. This provides agile installation process and faster response for the changing business demand.
