ADVANCED FEATURES

Extreme 400G Power:

The Dell EMC Z9664F-ON is purpose-built to deliver unprecedented 400GbE switching density and performance. Powered by the Broadcom Tomahawk 4 ASIC, it achieves 25.6 Tbps of non-blocking throughput and ultra-low latency under 700 ns, ensuring uncompromised performance even in the most demanding east-west traffic environments. This makes it ideal for AI/ML clusters, HPC workloads, and cloud-scale data center fabrics. With 64 × QSFP56-DD ports supporting flexible breakout modes (2×200GbE or 4×100GbE), network architects can scale from 100G to 400G seamlessly without infrastructure redesign.

Freedom to Choose OS:

Engineered for true open networking, the Z9664F-ON supports ONIE (Open Network Install Environment), allowing administrators to deploy their preferred network operating system. It is fully compatible with Dell SmartFabric OS10, SONiC, and Cumulus Linux, giving organizations freedom of choice in automation, telemetry, and orchestration. This flexibility simplifies integration with multi-vendor environments and supports network-as-code workflows, enabling programmable infrastructure that evolves with operational needs.

Built for Automation:

Designed for fully automated operations, the Z9664F-ON integrates natively with Ansible, Puppet, Chef, and Python SDKs. Its RESTCONF, NETCONF, and JSON-RPC APIs enable granular programmability for provisioning, telemetry, and lifecycle management. Zero-Touch Provisioning (ZTP) allows rapid deployment across large-scale environments, while streaming telemetry and real-time analytics deliver deep visibility into link utilization, packet latency, and device health. Together, these capabilities reduce operational complexity, speed up configuration, and ensure consistency across large multi-site networks.

Built-In Resilience:

Reliability is central to the Z9664F-ON design. It incorporates dual hot-swappable AC or DC power supplies and N+1 redundant fan modules, ensuring continuous operation during maintenance or component replacement. Airflow options—Front-to-Back (I/O to PSU) or Back-to-Front (PSU to I/O)—support flexible deployment in diverse data center cooling topologies. The system includes advanced health monitoring, predictive diagnostics, and field-replaceable components, minimizing downtime and improving mean-time-between-failure (MTBF) performance for critical infrastructure.

Smarter L2/L3 Virtualization:

The switch supports an extensive Layer 2/3 feature set with BGP, OSPF, IS-IS, and VRF-Lite routing capabilities, ensuring smooth integration into complex enterprise and service provider networks. Hardware-accelerated VXLAN and EVPN overlays deliver scalable, high-performance multi-tenant segmentation—ideal for modern cloud and edge environments. With IGMP Snooping, PIM-SM/SSM, and multicast optimization, the Z9664F-ON efficiently handles broadcast and streaming applications in converged network topologies.

Intelligent Traffic Control:

To maintain consistent performance across diverse workloads, the Z9664F-ON uses dynamic buffer allocation, WRED, and CoS-based scheduling to manage congestion intelligently. Each port supports 8 egress queues, allowing granular prioritization for latency-sensitive applications like AI inference, storage replication, and financial trading. Priority Flow Control (PFC) and DCBX/ECN ensure lossless Ethernet transmission in converged environments, while per-port statistics and telemetry enable proactive network optimization.

Multi-Layer Security:

Security is enforced through Layer 2/3/4 ACLs, RADIUS/TACACS+ authentication, and MAC-based port control, ensuring only authorized devices gain access. The switch supports DHCP Snooping, Dynamic ARP Inspection, and IP Source Guard to defend against spoofing and man-in-the-middle attacks. With Secure Boot, firmware integrity verification, and encryption protocols (SSHv2, SSL, SNMPv3), the Z9664F-ON provides a hardened, trusted networking foundation. Its hardware-level DoS protection ensures resilience against volumetric attacks and control-plane saturation.

Deep Network Insight:

Built-in telemetry, sFlow, Syslog, and SNMPv3 capabilities deliver continuous insights into network health, performance, and security. Advanced monitoring allows administrators to capture microbursts, detect anomalies, and implement predictive maintenance before service impact. Environmental sensors for temperature, power, and fan speed enable early detection of physical anomalies, while integration with analytics platforms supports centralized management, capacity planning, and trend analysis across distributed data centers.

Cloud-Native Ready:

With full support for VXLAN, EVPN, and automation-driven orchestration, the Z9664F-ON is optimized for leaf-spine, super-spine, and AI fabric architectures in cloud-native data centers. Its high density and low latency enable efficient east-west data flow, while interoperability with leading virtualization platforms such as VMware NSX, OpenStack, and Kubernetes supports elastic and programmable cloud environments. Combined with SmartFabric OS10 or SONiC, it forms a scalable, open, and automation-ready infrastructure for modern workloads.

Energy-Smart Design:

Built to support evolving network demands, the Z9664F-ON balances performance and sustainability with energy-optimized components and adaptive fan speed control. The efficient cooling design and variable power modes reduce operational expenses without compromising reliability. Its modular design ensures easy serviceability, while compliance with RoHS, WEEE, and REACH standards reinforces Dell’s commitment to eco-friendly, sustainable data center technology.
