The Evolution of NVM Express to Meet Cloud Determinism Requirements For NVM Devices




Abstract: SSDs are becoming very large (e.g., 16 TB in a single device). In Cloud environment, these SSDs are often hosting many different latency sensitive applications. By renegotiating the contract between the host and device, P99 and P9999 read latency can be bounded. The new contract provides other knobs, like a worse UBER to get lower maximum read time. Explore what is possible when the host and device collaborate, enabling the host to build a tapestry of fast NVMe SSDs across the Datacenter.
