48xSFP28+8xQSFP28 ports Data Center Switch

SST-48HX8CQB-AC is a high port density switch with 48xSFP28+8xQSFP28 ports in a single 1RU for data centers and high-end campus networks.

1RU 2Tbps Top-of-Rack Date Center SWITCH

48x25Gbps and 8x100Gbps ports is ideally suited for deployment at the server access layer in large enterprise data centers.

Delivers high-performance, high interface density and low latency to
Allow enterprises and carriers to build cloud-oriented data center networks.
I deal spine and top of rack(ToR) solution,allowing maximum flexibility,with port speeds spanning from 10Gbps to 100Gbps per port and port density that enables full rack connectivity to any server at any speed.

Use of Marvell Falcon ASIC and Intel Broadwell CPU with DDR4 memory and flash

Expansion enables custom software configurations.Supports the open source Open Network Install Environment(ONIE) for zero touch installation of SONiC networking operating system.
