The Innodisk CXL Add-in Card (AIC) is a CXL-based memory expansion solution designed for edge servers and on-premises AI computing environments.
By leveraging standard PCIe Gen 5 x8 interfaces and connectors, the CXL AIC enables flexible memory expansion without occupying traditional DIMM slots. As a CXL 2.0 Type 3 device supporting CXL.mem and CXL.io, it enables memory pooling and sharing, optimizing system memory resources to be allocated more efficiently across changing workload demands. Delivering scalable DDR5 capacity up to 256GB with 32GB/s of additional bandwidth, the CXL AIC supports fast memory access for latency-sensitive workloads. Its compact HHHL form factor ensures seamless integration into space-constrained edge systems, making it ideal for low-latency, real-time applications such as AI inference, 5G networking, high-frequency trading, and smart medical imaging.
EXPANDED MEMORY CAPACITY REQUIRES NO ADDITIONAL DIMM SLOTS
By utilizing standard PCIe Gen5 interfaces and connectors, the CXL AIC overcomes limitations in CPU-usable memory bandwidth and expands memory capacity for edge systems without occupying additional DIMM slots.
MEMORY POOLING FOR ELASTIC WORKLOADS
As a CXL 2.0 Type 3 device with CXL.mem and CXL.io support, the CXL AIC enables dynamic memory pooling and sharing at low latency. This capability ensures that memory resources can be flexibly allocated across hosts and workloads, significantly improving overall system efficiency.
HIGH BANDWIDTH, RAPID ACCESS FOR REAL-TIME APPLICATIONS
Built on PCIe Gen 5 x8 with up to 32GB/s of additional bandwidth, the CXL AIC delivers rapid memory access for high-frequency data workloads. By reducing memory access delay and communication overhead between the CPU and shared memory, it minimizes performance bottlenecks and enables faster data flow for latency-sensitive applications such as AI inference and network edge processing.
FLEXIBLE SCALABILITY WITH DDR5 UP TO 256GB
The CXL AIC supports flexible memory expansion up to 256GB, allowing capacity to be easily adjusted by swapping DDR5 RDIMM modules based on system requirements. When paired with Innodisk DDR5 RDIMM VLP memory, it further reduces space usage and improves internal layout flexibility for edge systems.
COMPACT HHHL DESIGN FOR EDGE DEPLOYMENT
The compact HHHL form factor of the CXL AIC ensures seamless integration into space-limited edge servers and systems. Its small footprint and optimized design make it ideal for space-constrained edge deployments such as micro data centers, 5G network infrastructure, and embedded AI platforms.
