Why E-series
Traditional DPUs use rigid pipelines with Arm cores only for exception handling. E-Series places all 64 Arm cores directly in the data path, delivering 4× the CPU performance of existing designs with a standard Linux programming model.
Software-defined architecture
Accelerate innovation and efficiency with easily programmable, software-defined silicon built for rapid development. Program with XDP, DPDK, SPDK. No proprietary SDK required. Arm System Ready.
There is no slow path
Unlike other DPUs the E1 places all cores on the data path, maximizing data throughput and efficiency across all workloads. 64 Neoverse N2 cores process every packet. The only DPU with no exception-handling slow path.
Built to scale
Converge compute, storage, and networking to simplify and scale your infrastructure.
E-Series DPUs
E1 Data Processing Unit
800G | 64 Arm Cores | 5nm
The industry's first 800G DPU. 64 Arm Neoverse N2 cores in the data path deliver 4× the CPU performance of existing designs. No slow path. Standard Linux development.
Available in three form factors:
- E1-Server: 1RU edge server
- E1-AIC: PCIe add-in card
- E1-SoC: Silicon for custom designs
Key features
64 Arm N2 cores
All cores in the data path. No slow path for exception handling.
800 Gbps networking
Flexible network port configuration up to 2× 400GbE ports with line-rate processing.
Standard Linux
XDP, DPDK, SPDK. Your existing tools and code work here.
Arm SystemReady Certified
Runs unmodified Linux distributions including Debian, Ubuntu, and SONiC.
Coherent architecture
Unified control and data plans
E-Series architecture
E-Series integrates compute, networking, and storage acceleration on a single die with a coherent memory architecture. Unlike traditional DPUs that require packet copies between domains, E-Series enables zero-copy data movement across all functions.
Familiar development model
Unlike DPUs that require P4 or proprietary tools, E-Series uses the same Linux frameworks your team already knows.
XDP
Express Data Path for high-performance packet processing.
DPDK
Data Plane Development Kit for userspace networking.
SPDK
Storage Performance Development Kit for NVMe acceleration.
Sonic
Full SONiC DASH support for cloud-native networking.
Validated performance
Unlike DPUs that require P4 or proprietary tools, E-Series uses the same Linux frameworks your team already knows.
First to Pass DASH Testing at 800G Scale
E1 exceeded SONiC-DASH Hero 800G benchmark requirements by 19%, achieving 14.3 million connections per second with zero dropped packets.
Key Results:
- 14.3M connections/second (19% above requirement)
- 120M background connections maintained
- Zero packet drops under full load
— Independent test lab validation, November 2024
“E1 should deliver about four times the CPU performance of existing DPU designs.”
