CISCO N9K-C93400LD-H1 NEXUS 9K 48X 50G SFP56 + 4X 400G QSFP-DD

The advent of 5G networks creates unprecedented opportunities and challenges for telcos and enterprises to deliver secure services and new user experiences. Each new generation of mobile networks has driven the need for increased precision and accuracy in synchronization standards and solutions. 5G technology is needed to support Ultra-Reliable Low-Latency Communications (URLLC) services, and new revenue-generating services such as autonomous vehicle connectivity and eHealth services are simply not possible without highly accurate and reliable time synchronization. Even such services as massive Industrial Internet of Things (IoT) and other industrial automation services require reliable time synchronization.

Furthermore, Artificial Intelligence and Machine Learning (AI/ML) applications are being used increasingly in today's data centers, and the Cisco Nexus 9000 Series Switches have the hardware and software capabilities to provide the right latency, congestion-management mechanisms, and telemetry to meet the requirements of those applications. The Cisco Nexus 9000 Series Switches address the need for high-performance, power-efficient, compact switching in the networking infrastructure, designed to support 400G fabrics for next-generation leaf and spine designs.

Large-cloud and data-center networking teams require a flexible, reliable solution that efficiently manages, troubleshoots, and analyzes their IT infrastructure. In addition, they need security, automation, visibility, analytics, and assurance. Coupled with tools such as Cisco Nexus Dashboard Insights for visibility and Nexus Dashboard Fabric Controller for automation, Cisco Nexus 9000 Series Switches are ideal platforms to build a high-performance AI/ML network fabric.

The Cisco Nexus 93400LD-H1 Switch introduces Precision Time Protocol (PTP) with Class C 1588 timing accuracy to the Nexus 9000 fixed-switch portfolio. Through PTP and Synchronous Ethernet (SyncE), it delivers frequency and time distribution with high accuracy. The switch is built with backward-compatible 400G optical interface Quad Small Form-Factor Pluggable-Double Density (QSFP-DD) ports for high density aggregation at 400 Gbps speed; it also offers various lower port speeds and densities, including 10, 25, and 50 Gbps. The Cisco Nexus 93400LD-H1 Switch is based on Cisco^®Cloud Scale technology equipped to support next-generation cloud architecture.

The Cisco Nexus 93400LD-H1 is a 1-Rack-Unit (1RU) 48-port 50 Gigabit Ethernet, 4-port 400 Gigabit Ethernet switch that supports 8 Tbps of bandwidth. The switch provides 40MB of on-die packet buffer with MACsec capability on all ports.

Architectural flexibility

Cisco Nexus 9000 Series Switches support Cisco Application Centric Infrastructure (Cisco ACI^®), Cisco NX-OS VXLAN EVPN, Cisco IP Fabric for Media, Cisco Nexus Data Broker, and IP routed on Ethernet switched Layer-2 fabrics using a comprehensive set of unicast and multicast IPv6/IPv4 and Ethernet protocols.

• Purpose-built Cisco NX-OS Software operating system with comprehensive, proven innovations. The operating system is modular, with a dedicated process for each routing protocol: a design that isolates faults while increasing availability.
• Industry-leading Cisco Software-Defined Networking (SDN) solution with Cisco ACI support. Cisco ACI is a holistic, intent-driven architecture with centralized automation and policy-based application profiles.
• Support for standards-based VXLAN EVPN fabrics, inclusive of hierarchical multisite support (Refer to VXLAN network with MP-BGP EVPN control plane for more information.)
• Three-tier BGP architectures, enabling horizontal, nonblocking IPv6 network fabrics at
