Type 1 (CXL.io) CXL device
This protocol is used for device initialization, link-up, enumeration and device discovery. It is used for devices like FPGAs and IPUs that support CXL.io. Type 1 devices implement a fully coherent cache but no host-managed device memory.
Type 2 (CXL.缓存)CXL设备
This protocol implements an optional coherent cache and host-managed device memory. Typical applications are devices that have high-bandwidth memory attached.
Type 3 (CXL.mem) CXL device
This protocol is used only for host-managed device memory. Typical applications are as memory expanders for the host.

Modern compute architectures are prone to the “memory wall” problem. CXL提供了必要的体系结构来平衡计算和内存的伸缩差距. 它创造了一个新的载体，通过内存扩展实现经济可行的内存解决方案, 影响DRAM位增长率.
Additionally, CXL灵活且可扩展的体系结构提供了更高的计算和内存资源利用率和操作效率，可以根据工作负载需求扩展或扩展资源.

现代并行计算机体系结构容易出现限制应用程序处理性能的系统瓶颈. Historically, 这被称为“记忆墙”。, 微处理器性能的提高速度远远超过DRAM内存速度的提高速度.
用于内存-设备内聚和一致性的CXL协议属性通过支持服务器DIMM插槽之外的内存扩展来解决内存墙问题. CXL内存扩展是一种双管齐下的方法，通过增加带宽来克服内存墙，同时为支持CXL的服务器增加数据密集型工作负载的容量.
CXL附加内存为分层内存存储的新领域提供了巨大的增长机会，并支持独立于CPU内核的内存扩展. CXL将有助于维持较高的DRAM位增长率, but don’t expect CXL to cause an acceleration in DRAM bit growth. 总体而言，这对DRAM的净增长是有利的.

CXL是一种经济有效的方法, flexible, and scalable architectural solution that will shape the data center of the future. 它将改变传统的机架和堆栈架构的服务器和fabric交换机在数据中心的部署方式.
Purpose-built servers that have dedicated fixed resources comprised of CPU, memory, 网络和存储组件将让位于这些更灵活和可扩展的架构. Servers in the rack – once interconnected to fixed resources for network, 存储和计算——将动态组合，以满足人工智能和深度学习等现代和新兴工作负载的需求. Eventually, the data center will migrate towards complete disaggregation of all server elements, 包括计算, memory, network, and storage.
