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.
