铠侠展示针对NVMe驱动器的RAID卸载方案Kioxia Demonstrates RAID Offload Scheme for NVMe Drives
➀ 铠侠在FMS 2024上展示了针对企业级SSD的新RAID卸载方法，旨在解决RAID阵列中的性能扩展问题。➁ 该方案利用PCIe直接内存访问和SSD控制器的内存缓冲区（CMB）来避免数据传输到CPU。➂ 概念验证显示了CPU和系统DRAM利用率的显著降低，铠侠计划将此功能贡献给NVM Express工作组，以期实现标准化。➀ Kioxia demonstrated a new RAID offload methodology for enterprise SSDs at FMS 2024, aiming to address performance scaling issues in RAID arrays. ➁ The proposed solution utilizes PCIe direct memory access and the SSD controller's memory buffer (CMB) to avoid data movement to the CPU. ➂ The PoC showed significant reductions in CPU and system DRAM utilization, and Kioxia plans to contribute this feature to the NVM Express working group for potential standardization.---
