Xsight Labs Launches E1L DPU for Global Edge AI Networks

Xsight Labs announced on October 8, 2026, the launch of the E1L, the newest member of its E-Series data processing unit (DPU) portfolio. The Arm-based device brings fully programmable DPU capability at up to 200G to power envelopes as low as 25 watts TDP, or 15 watts typical, in its eight-core, 100G configuration.

A power-efficient DPU solution for edge and embedded infrastructure

The chip is powered by Arm Neoverse N2 cores and is designed for edge, embedded, and other power-constrained infrastructure.

The company positions the E1L as addressing a gap for operators: until now, bringing DPU offload into a power-constrained site has meant either a proprietary software stack sized for one chip or leaving offload out entirely.

The E1L offers full DPU offload from 25 watts, running on the same architecture and software as the company's 800G E1 DPU.

According to Xsight Labs, the two chips share full cross-platform compatibility, so software written for one runs on the other, using standard Linux tools and no proprietary licensing.

AI agents and the case for offload at the edge

In its announcement, Xsight Labs framed the E1L against a shift in AI workloads, from models that answer questions to agents that take action. In that model, every agent query, lookup, and tool call becomes traffic to databases, storage, and the network, and that infrastructure work lands on the same host CPUs intended for the AI workload itself.

Agents touching critical systems also raise the bar for isolation, the company noted. The E1L is designed to take that infrastructure work off the host, fully or in part, and run it in a separate, isolated domain, at a power envelope that fits sites outside the data center.

Open standards and merchant silicon

Unlike conventional network interfaces, DPUs offload networking, security, and storage tasks from the main server CPU. While a network interface card simply moves data, a DPU carries its own processors and memory and runs the infrastructure software itself.

By building on open standards, Xsight Labs provides a fully programmable, merchant-silicon alternative to proprietary DPUs, one that accelerates software-defined infrastructure without proprietary architectures or licensing, according to the company.

The E1L is built on Arm Neoverse CSS N2 and designed for Arm SystemReady compatibility. It runs standard Linux and familiar software frameworks, including XDP, DPDK, and SPDK, allowing infrastructure teams to develop and deploy programmable networking, storage, and security services without a proprietary software environment.

The power figures start with the silicon: the E1L is built on TSMC's N5 process, the same node as the E1, which the company says allows it to do the same work in a smaller form factor with less energy and less heat. Total power is configurable at 25 W, 30 W, and 40 W TDP, with typical draws of 15 W, 18 W, and 25 W, respectively.

Alongside the 800G E1, which draws under 75 W, the E1L completes an E-Series that runs one software stack from 100G at the edge to 800G in the core.

Key specifications

The E1L is offered in configurations with 8, 16, or 22 Arm Neoverse N2 cores. Networking capacity reaches up to 200 Gbps over 4 SerDes lanes. Memory support extends to two DDR5-5200 interfaces with inline encryption.

On the security side, the device provides line-rate AES-GCM for IPsec offload. The host interface consists of 20 PCIe Gen5 lanes across 6 dual-mode controllers with SR-IOV support.

The device is available in three form factors: a discrete device, a COM Express module, and a 1RU server, all sharing the same software and feature set.

Executive commentary

"The E-Series now scales from 100 gigabits at the edge to 800 gigabits in the core on a unified architecture and software stack. Operators told us they needed DPU capability within the power envelopes they already rely on.

The E1L delivers that," said Yossi Meyouhas, CEO of Xsight Labs. Eddie Ramirez, Vice President of Go-To-Market, Cloud AI at Arm, said, "AI infrastructure is expanding across a broader range of environments, making performance per watt and software flexibility critical for deployment.

By building on Arm Neoverse CSS N2, Xsight Labs is bringing programmable, efficient compute from the edge to the data center while giving developers the benefits of a common software ecosystem."

Availability

The E1L is scheduled to begin sampling in the second quarter of 2027. Xsight Labs will present the E1L at the 2026 Open Compute Project (OCP) Global Summit, held October 12 to 15 in San Jose, where the company is participating as an OCP Bronze member.
