Mellanox Spectrum-3 SN4700 - Switch - L3 - managed - 32 x 400 Gigabit QSFP-DD - front to back airflow - rack-mountable

• Performance without compromise
  Packet buffer architecture has a major impact on overall switch performance. The Mellanox Spectrum-3 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, Mellanox Spectrum-3 is able to provide a high-performance fair and bottleneck-free data path for mission-critical applications.
• Pervasive visibility for simplified operations
  Mellanox Spectrum-3 provides deep and contextual network visibility, which enables network operators to proactively manage issues and reduce mean time to recovery/innocence. Mellanox Spectrum's What Just Happened (WJH) feature leverages the underlying silicon and software capability to provide granular and event-triggered information about infrastructure issues.
• Features without compromise
  For modern data center infrastructure to be software defined and agile, both its compute and network building blocks need to be agile. Mellanox Spectrum-3 features a unique feature rich and efficient packet processing pipeline that offers rich Data Center Network virtualization features without compromising on performance or scale. Mellanox Spectrum-3 is a programmable pipeline and a deep packet parser/editor that can process payloads up to the first 512B. Mellanox Spectrum-3 supports single pass VXLAN routing as well as bridging. Additionally, Mellanox Spectrum-3 supports advanced virtualization features such as IPv6 segment routing, and Network Address Translation (NAT).
• Scale without compromise
  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 and mega-clouds increase by up to an order of magnitude or more. To answer these needs for scalability and flexibility, Mellanox Spectrum-3 uses intelligent algorithms and efficient resource sharing, and supports unprecedented forwarding table, counters and policy scale.

Mellanox SN4700 spine/super-spine offers 32 ports of 400GbE in a compact 1U form factor. It enables connectivity to endpoints at varying speeds and carries a throughput of 25.6Tb/s, with a landmark 8.4Bpps processing capacity. As an ideal spine solution, the SN4700 allows maximum flexibility, with port speeds spanning from 1GbE to 400GbE per port.
