Xsight Labs Expands E-Series DPU Portfolio with the E1L, a Fully Programmable DPU Starting at 25 Watts

Arm-based E1L delivers full DPU offload from 25 watts, on the same open software as the 800G E1

SAN JOSE, Calif. and TEL AVIV, Israel, Oct. 8, 2026 /PRNewswire/ -- Xsight Labs today announced the E1L, the newest member of its E-Series data processing unit (DPU) portfolio. The E1L brings fully programmable DPU capability, at up to 200G, to as little as 25 watts TDP (15 watts typical) in its eight-core, 100G configuration, powered by Arm® Neoverse® N2 cores and designed for edge, embedded and other power-constrained infrastructure. Like the E1, it is built on open standards and runs standard software without proprietary licensing, and with full cross platform compatibility, software written for one, runs on the other.

For operators, bringing DPU offload into a power-constrained site has meant a proprietary software stack sized for one chip, or leaving offload out. The E1L changes that: full DPU offload from 25 watts, on the same architecture and software as the 800G E1, so an offload written once runs from a 25-watt DPU at the edge to an 800G DPU in the data center, on standard Linux tools and with no proprietary licensing.

AI is shifting from models that answer questions to agents that take action. 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 meant for the AI workload. Agents touching critical systems also raise the bar for isolation. The E1L takes that infrastructure work off the host, fully or in part, and runs it in a separate, isolated domain, at a power envelope that fits sites outside the data center.

The E1L is scheduled to begin sampling in the second quarter of 2027.

Open, programmable silicon for the modern data center
Unlike conventional network interfaces, DPUs offload networking, security and storage tasks from the main server CPU. A network interface card moves data; a DPU also 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 aternative to proprietary DPUs, one that accelerates software-defined infrastructure without proprietary architectures or licensing.

The E1L: low-power DPU for edge and embedded systems
Engineered for space- and power-constrained environments and for embedded applications, where specialized data center cooling is limited or absent, the E1L brings fully programmable DPU capability, at up to 200 Gbps, with TDP from 25 W to 40 W and typical draw of 15 to 25 W. The power figure starts with the silicon: the E1L is built on TSMC's N5 process, the same node as the E1, so it does the same work in a smaller form factor, with less energy and less heat.

Built on Arm Neoverse CSS N2 and designed for Arm SystemReady compatibility, the E1L runs standard Linux and familiar software frameworks including XDP, DPDK and SPDK, so infrastructure teams can develop and deploy programmable networking, storage and security services without a proprietary software environment. The E1L is offered as a discrete device, a COM Express module and a 1RU server, all sharing the same software and feature set. 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.

E1L key specifications

• Compute: 8, 16 or 22 Arm Neoverse N2 cores
• Networking: up to 200 Gbps over 4 SerDes lanes
• Memory: up to 2 DDR5-5200 interfaces with inline encryption
• Security: line-rate AES-GCM for IPsec offload
• Host interface: 20 PCIe Gen5 lanes across 6 dual-mode controllers with SR-IOV support
• Power: configurable 25 W, 30 W and 40 W TDP (typical draw 15 W, 18 W and 25 W)
• Software: off-the-shelf Linux distributions; XDP, DPDK and SPDK integration

"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.

"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," said Eddie Ramirez, Vice President of Go-To-Market, Cloud AI, Arm.

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, October 12 to 15, in San Jose, as an OCP Bronze member.
