Challenges and Effects of EDSFF-based NVMe-oF Storage Solution
EDSFF (Enterprise and Data Center SSD Form Factor) SSD has been widely adopted in hyper-scale data centers because of superior manageability, serviceability, and power/thermal characteristics. The new form factor provides high performance (support up to PCIe Gen6) and high capacity (up to 128TB), and allows to support new type of devices like NIC, accelerator, and CXL DRAM device in a system. However, adopting of EDSFF in NVMe-oF system is non-trivial. For example, with EDSFF SSD, the capacity of single storage server can easily have Petabyte in total.
