HPE introduces super-spine M-series offering with high performance SN4600M launch

SN-4600_Launch_NewBlog_shutterstock_1091738663.pngStorage networks require data transfer to be consistent. Networking for high-performance workloads and next generation storage connectivity must be predictable and fast, so transferring network and storage data over a reliable network requires predictability and guaranteed performance to handle the shared data flow. This means that dropped packets and intermittent latency on a switch can have a detrimental effect on the overall systems efficiency. HPE M-series delivers network speed and agility to keep pace with the most intense workloads.

The HPE SN4600cM Switch, the first SN4600M family member, offer a 100GbE-based network platform capable of delivering unprecedented networking speed and agility to keep pace with the most intense workloads small to large scale enterprises can produce. With port speeds spanning from 1Gb/s to 100 Gb/s and a switching capacity of 12.8Tb/s from 64 ports at 100GbE, the switch enables non-blocking throughput at wire-speed transfers-across all packet sizes. All this enables the SN4600cM to deliver a landmark 8.4Bpps processing capacity and an uncompromising ultra-low cut-through latency in a compact 2RU form factor. The SN4600cM expands the HPE M-Series Ethernet switch family to End-of-Row, Core, and Super Spine deployments and is optimized for virtualized environments, hyperconverged infrastructure, and low-latency storage deployments.

Purpose-built for the modern datacenter, the SN4000 series of switches combine high performance packet processing, rich datacenter features, cloud network scale and visibility with flexible form factors. The SN4000 platforms are based on Spectrum-3 switch silicon and support up to a whopping 25.6Tbps of bidirectional switching capacity. Built for the modern data center, the SN4000 supports:

  • Advanced in-band granular telemetry with fine-grain visibility What Just Happened (WJH)
  • Rich data center features at unprecedented scale
  • Consistent performance and ultra-low-latency
  • Fair bandwidth sharing with fully shared packet buffers
  • Comprehensive Layer-2, Layer-3 and RoCE
  • Programmable pipeline that can programmatically parse, process and edit packets
  • Intelligent hardware-accelerated data movement, congestion management and load balancing for RoCE and Machine learning applications

Delivering the highest feature set at the right price allows the Ethernet infrastructure to best support a variety of use cases, including media and entertainment/streaming video, financial services industry, virtualized data centers, and next generation storage, including software-defined storage and NVMe flash.

With HPE M-Series switches, you can:

  • Optimize Storage. Modernize your network to eliminate limitations and bottlenecks that can be caused by the addition of flash storage.
  • Enjoy efficient network performance. Avoid packet loss, provide predictable performance with line-rate packet delivery across all ports and all packet sizes.
  • Realize breakthrough economics. Make better use of your data center resources with the highest port density per rack unit, and the industry’s lowest power consumption.
  • Accelerate business innovation. Utilize 1/10/40Gbps Ethernet connectivity for existing workloads and enhance connectivity utilizing built-in 25/50/100Gbps capabilities to respond quickly to business needs, and stay on the leading edge of Ethernet switching technology

Whether you are or are not supporting AI/ML or DA workloads today, most modern data centers are highly virtualized, and run on solid-state storage. The introduction of NVMe storage is just around the corner and slated to further push performance standards. For both fast NVMe storage and all computational inferencing workloads, predictable and reliable data delivery depends on fast and accurate data delivery – and this starts at the network. The M-Series Ethernet switches meet and exceed the most demanding criteria for wire-speed performance so real-time decisions from the most robust cognitive computing applications can thrive.

Rapid improvement of data center computing and low-latency storage solutions have transferred data center performance bottlenecks to the network. 10GbE networks only create delays, and will become a major constraint in network performance. Therefore, today’s data centers should be designed to handle this anticipated bandwidth with a low latency, lossless Ethernet Storage Fabric. Beyond the performance advantages, the economic benefits of running NVMe and AI workloads over Ethernet are substantial. M-series switches deliver this unbeatable performance at an even more unbeatable price point, yielding outstanding ROI.

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, NAS, or Object storage systems. With cost-effective options such as pay-as-you-grow licensing, seamless speed transition from 1GbE to 100GbE and support for next-generation storage such as software-defined, scale-out, distributed and NVMe, ensure your M-series fabrics allows for implementing significant speed and architecture upgrades over time.
