HPE 25GbE 48SFP28 12QSFP28 Power to Connector Airflow Switch SN3420M with NVIDIA Cumulus

The HPE Storage Switch M-series SN3420M is a data center switch offering a 1U 48-port 25 GbE SFP28 + 12-port 100 GbE QSFP28 connectivity.
Each switch delivers forty-eight SFP28 25 GbE ports and also twelve 100 GbE ports, that may be further split into forty-eight 1, 10, or 25 GbE ports, twelve 40 GbE ports, or twenty-four 50 GbE ports.
Each switch delivers data rates from 1 GbE to 100 GbE (1, 10, 25, 40, 50, 100 GbE) providing future-proofing for connectivity options.

The HPE Storage Switch M-series SN3420M delivers predictable and consistent throughput (3.58 Bpps) regardless of the packet size being transferred, the mixture of ports that are sending data, and even within mixed-speed environments.
It provides wire-rate performance with zero packet loss across frame sizes, avoiding any negative impact on applications that could occur with frame loss as unexpected packet loss is unacceptable in modern data centers, especially within a storage network.

The HPE Storage Switch M-series SN3420M provides a flexible combination of ports, allowing great flexibility and efficiency, simplifying scale-out environments, and saving on total cost of ownership (TCO).
Enhanced port configuration enables high-speed rack connectivity to the server at 1/10 GbE or 25 GbE speeds with 100 GbE uplink ports that allow for a variety of blocking ratios that suit specific application requirements.

The HPE Storage Switch M-series SN3420M provides ultra-low latency of under 425 ns port-to-port. This is advantageous for flash storage, which has moved latency bottlenecks from storage access to the network, as well as for the burst nature of today’s software-defined and cloud data center traffic.
The buffering architecture of HPE Storage M-series SN3420M switches provides superior microburst absorption for applications that burst data at random intervals.
