CXLcache

CXLcache is a high-speed, hardware-based caching technology designed for commodity servers and datacenter environments. It is based on the Cache Express and Link protocol, a low-latency interconnect standard for fast data transfer between components. CXLcache integrates directly with the CPU's memory controller, enabling accelerated data access and reduced latency for frequent and random workload access patterns.

The primary purpose of CXLcache is to alleviate memory bottlenecks in modern workloads, such as large-scale databases, cloud storage, and real-time analytics. By providing a separate, high-speed cache, CXLcache can significantly reduce memory latency and data transfer times, leading to improved system responsiveness and overall performance.

CXLcache is designed to work seamlessly with existing server systems, without the need for CPU or system architecture changes. It integrates with the system's memory hierarchy, including DRAM and NVMe storage, to provide a single, unified memory platform. This ensures maximum flexibility and compatibility for various use cases, from large-scale cloud deployments to on-premises datacenter environments.

CXLcache is built for low-latency, high-bandwidth applications that require fast and efficient data access. Its architecture is optimized for multitenant environments and supports both single-root and multi-root interconnects, providing a scalable and flexible solution for modern datacenter workloads. By leveraging CXLcache, system administrators and developers can build performant, high-density server systems that meet the demands of modern computing workloads.
