What protocol is required to utilize SCM for high performance?

The correct protocol for utilizing SCM (Storage Class Memory) for high performance is NVMe (Non-Volatile Memory Express). NVMe is specifically designed to unlock the potential of high-speed storage technologies, such as SSDs, by providing a more efficient and faster data transfer path between the storage media and the CPU.

One of the key advantages of NVMe is its ability to handle multiple queues and a large number of commands in parallel, which significantly reduces latency and increases throughput compared to older storage protocols. This capability is crucial for applications that demand high performance and low response times, making NVMe the ideal choice for leveraging the advanced capabilities of SCM.

While the other protocols mentioned—HTTPS, FTP, and TCP/IP—are widely used for data transmission and communications, they are not optimized for the unique performance characteristics required by SCM technology. HTTPS and FTP are primarily application layer protocols designed for secure web browsing and file transfer, respectively, while TCP/IP serves as the foundational communication protocol for networks but does not address the high-speed data transfers necessary for leveraging SCM effectively.
