Fully programmable bare-metal smart switch provides greatest service density available at less than half the power with four times the performance per rack units.

News Highlights:

Xsight Labs announces collaboration with Interface Masters Technologies on the Tahoe 3828 EXA (Enhanced Switch Appliance), the industry’s highest performance Ethernet port speeds and connection-per-second flow learning rate, lowest power-per-connection, and highest all layer SDN service density.

Unparalleled 1 RU EXA supports advanced applications including AI Edge Inference Gateway, AI-enabled Distributed Firewall Security appliance, and highest performing cloud-scale AI enabled real-time analytics and packet-broker platform.

The Enhanced Switch Appliance is an Open Networking Platform and will begin shipping to strategic customers in early Q1 2026 with general availability from software partners beginning in Q2 2026.

SAN JOSE, Calif. & TEL AVIV, Israel--(BUSINESS WIRE)--

Xsight Labs today announced a strategic collaboration with Interface Masters Technologies to deliver the industry’s greatest service density and lowest power-per-RU Smart Switch offering fully programmable SDN for all layers – OSI L2-L7. The Tahoe 3828 EXA Enhanced Switch Appliance delivers over four times the service density with half the power per Gbps over alternative Smart Switch options, while only requiring 1RU of rack space. The SONiC Network Operating System, including support for a 1.6T SONiC DASH Hero datapath is available. The EXA will be offered by both Interface Masters and their partners with complete software applications.

Examples include:

AI Edge Inference and cloud gateways, including Carrier NAT and load balancing services

Enabling next generation hyperscale and Neocloud multitenancy with extreme scale and the highest networking bandwidth

In-network distributed stateful security

Advanced AI microservice orchestration with advanced dynamic policy enforcement

Packet brokers, advanced instrumentation telemetry, and packet tracing

High Availability Network and security appliances

5.5G and 6G terrestrial and satellite base stations

Warm storage controller for CDN media & broadcast applications

The Interface Masters EXA is built on two TSMC N5 chips by Xsight Labs employing 112G SerDes on both the switch and DPUs, ensuring the highest performance and superior economics. The Xsight Labs development model avoids unnecessary complexity and proprietary vendor lock-in. The E1 supports off-the-shelf Linux and standard DPDK or other common data plane tools, as opposed to overly complex architectures found in other DPUs. This open-programming model enables the fastest time to market with the greatest feature velocity.

“As AI redirects budgets away from large established markets, including traditional mobility, enterprise, and cloud, these new all-layer smart switches will enable the delivery of new mission-critical services,” said Ted Weatherford, VP Business Development, Xsight Labs. “With the disruptive TCO and the extreme feature velocity offered by the Tahoe 3828 EXA, software-defined smart switches are destined to replace dumb switches in the rapidly evolving AI era.”

The initial EXA is available in a 1RU form factor with 28 x 400GE networking ports of connectivity and with 128 x N2 Arm cores running Ubuntu. The system is Arm SystemReady (SR) Level 6, allowing any standard Linux distribution to run 64-bit cloud-native applications. The accelerating pace of AI and Edge Inference applications is best served by an open community with a democratized approach provided by the T3828 EXA.

Feature Highlights:

Edge SDN & Linux Compute Leadership (128 Arm N2 cores total; 11.2Tbps) 28 x 400G QSFP-112 Ethernet networking

High-end timing, supporting multiple 1588v2 Precision Time Protocol (PTP) profiles for emerging AI, mobility, and legacy applications

1.6T SONiC DASH performance leadership, hundreds of millions of flows with zero packet loss

Greater than 28 MCPS Vnet-Vnet DASH smart NIC virtual services pooling performance

128GB deep buffer Traffic Management with Hierarchical Quality of Service scheduling
