Alveo SN1000 SmartNIC Accelerator Card

Important Information

While the Alveo SN1022 adaptive SmartNIC is actively being supported for current users, AMD recommends that all new designs target the Alveo U45 network accelerator. Contact an AMD product specialist for any questions.


Product Description

The AMD Alveo SN1000 is the industry’s first SmartNIC offering software-defined hardware acceleration for all function offloads in a single platform. SN1000 SmartNICs directly offload CPU-intensive tasks to optimize networking performance, with an architecture that can accelerate a broad range of custom offloads at line rate, including support for customer-built and third-party offloads.

Based on the AMD 16nm UltraScale+™ architecture, SN1000 SmartNICs are powered by the low-latency AMD XCU26 FPGA and a 16-core Arm® processor.

Key Features & Benefits

P4 Programmability

The SN1000 features full protocol-level offload acceleration customization, application-specific data paths, and the ease of P4 high-level language programming. Vitis Networking,  P4 toolkit from AMD, enables customers to compose custom offloads and tweak existing offloads to handle new protocols and applications without replacing hardware.

Customized Offloads

SN1000 SmartNICs provide software-defined hardware acceleration for a wide range of networking, security, and storage offloads.

  • Network: Open vSwitch and virtualization acceleration (
  • Security: IPsec, kTLS and SSL/TLS
  • Storage: Virtio.blk, NVMe™ over TCP, Ceph, and compression and crypto services

Onload™ - Application Acceleration Software

Onload™ dramatically accelerates and scales network-intensive applications such as in-memory databases, software load balancers, and web servers. With Onload, data centers can support 400% or more users on their cloud network while delivering improved reliability, enhanced quality of service (QoS) and higher return on investment, without modification to existing applications.

Onload allows data centers to realize:

  • Improved elasticity and efficiency, leading to a lower total cost of ownership (TCO)
  • Increased peak transaction rates, eliminating service brownouts
  • Reduced network jitter with greater response times, equating to superior quality of service


  • Add 400% or more users
  • Improve messagerates by 100%
  • Minimize server footprint 25%
  • Reduce Latency by 50%
  • Experience near zero jitter
  • Maxmize capex & opex
  • Enhance quality of service

Extending Data Center Investments

Onload delivers a return on capex investments by allowing data centers to redeploy 25% or more of their load-balancing servers for other tasks. Alternatively, data centers can attain a reduction in operational expenses (opex) by shrinking the overall server footprint.

Use Case Application(s) Performance Increase Benchmark Documents
In-Memory Databases Couchbase, Memcached, Redis 100%
Software Load Balancers NGINX Plus, HAProxy 400%
Web Servers/ Applications NGINX Plus, 50%

How Fast Can Your Applications Go?

Onload accelerates nearly all network-intensive TCP-based applications. Typical performance improvements when utilizing Onload include:

AMD has produced a series of cookbooks that outline the servers we used, the configuration done, and exactly what testing was completed. The purpose of these cookbooks is to enable customers to reproduce the results obtained, as sometimes they can appear somewhat remarkable.

Ensuring Uptime and Network Compatibility

Onload is built from the same I/O software technology that powers nearly every financial market and high-frequency trading application on the planet. POSIX compliant, Onload ensures compatibility with TCP-based applications, management tools, and network infrastructures. In addition, Onload provides RDMA-like performance without requiring a forklift upgrade to the data center’s network infrastructure and can be deployed across x86-based platforms running Linux – bare metal, virtual machine or container.
