HPE adds groundbreaking 200GbE platform to M-series Ethernet Switch Family

Hewlett Packard Enterprise introduces the next generation of the M-series 200GbE data center switching platform, addressing evolving data center demands for workloads needing high performance and low latency.

M-Series_Ethernet-Switch_200GbE_blog.pngHPE is expanding the M-series offering with the introduction of the 32-port 200GbE SN3700M switch. Powered by the 50G PAM-4 based Spectrum-2 ASIC, the SN3000M carries a bidirectional switching capacity of up to 12.8Tb/s with a landmark 8.33Bpps packet processing rate. Purpose-built for the modern data center, the HPE M-series switches combine high-performance packet processing, rich data center features, cloud network scale, and visibility with flexible form factors.

As an ideal spine solution, the SN3700M allows maximum flexibility, with port speeds spanning from 10GbE to 200GbE per port. The SN3700M is also available for dedicated 100GbE Data Center connectivity. SN3700cM can also be used as a high density 10/25GbE leaf when used with splitter cables. The SN3700cM allows for maximum flexibility, with ports spanning from 1GbE to 100GbE with port densities enabling full rack connectivity to any server at any speed and a variety of blocking ratios. Ports are fully splittable up to 128 x 10/25GbE ports.

The HPE M-series SN3000M platforms deliver high performance, consistent low latency, along with support for advanced telemetry features, making it the ideal choice for web-scale IT, cloud, hyperconverged storage, and data analytics applications. There is an increasing need to access data faster than ever before, and – to accommodate growing workloads, rising east-west traffic levels, and flash-based storage – high bandwidth, low-latency networks become paramount.

HPE’s SN3000M provides full wire speed, cut through-mode latency, on-chip fully-shared 42MB packet buffering, and flexible port use, in addition to advanced capabilities. Combining a wide range of innovations in the area of programmability, telemetry, and tunneling with industry-leading performance, it is also capable of addressing complex storage networking requirements in modern data centers.

Features of the HPE M-series SN3000M Ethernet switches, built on the Spectrum-2 ASIC

Groundbreaking performance

Packet buffer architecture has a significant impact on overall switch performance. The Spectrum-2 packet buffer is fully shared across all ports, supporting cut-through line rate traffic from all ports without compromising scale or features. With its fast packet buffer, it’s able to provide a high-performance fair and bottleneck-free data path for mission-critical applications.

Fine-grain visibility

The SN3000M provides deep and contextual network visibility, enabling network operators to proactively manage issues and reduce mean time to recovery/innocence. The What Just Happened (WJH) feature leverages the underlying silicon and software capability to provide granular and event-triggered information about infrastructure issues.

Unprecedented agility

For a modern data center infrastructure to be software-defined and agile, both its compute, and network building blocks need to be agile. The SN3000M features a unique feature-rich and efficient packet processing pipeline that offers rich data center network virtualization features without compromising performance or scale.

Massive Scale

The number of endpoints in the data center is increasing exponentially. With the current shift from virtual machine-based architectures to container-based architectures, the high-scale forwarding tables required by modern data centers increase up to an order of magnitude or more. HPE M-series spectrum-based switches use intelligent algorithms and efficient resource sharing and support unprecedented forwarding tables, counters, and policy scales.

End-to-end solution

Rapid data center computing and low-latency storage solutions have transferred data center performance bottlenecks to the network. 10GbE networks create delays, becoming a significant constraint in network performance. Therefore, data centers need to handle anticipated bandwidth with low latency, lossless Ethernet storage fabrics. Beyond the performance advantages, the economic benefits of running NVMe and AI workloads over Ethernet are substantial. M-series switches deliver unbeatable performance at an even more unbeatable price point, yielding outstanding ROI.

 Ensure your M-series fabrics allows for implementing significant speed and architecture upgrades over time with cost-effective options such as pay-as-you-grow licensing, seamless speed transition from 1GbE to 200GbE, along with support for next-generation storage such as software-defined, scale-out, distributed, and NVMe storage.

The HPE M-series Ethernet switch family offers industry-leading, high-bandwidth, and the lowest-latency for a cost-effective solution to connect primary, secondary, hyperconverged, software-defined infrastructure, NAS, and object-based storage systems.
