Abstract
Your typical SSD is very badly behaved with regard to latency. Background tasks interfere with I/O requests. As drives increase in size beyond a typical working set, multiple users interfere with each other (noisy neighbor). Scale out systems such as those assembled by Hyperscalers, are not tolerant of today’s long tail of SSD latency. In order to address these requirements, the storage industry through the NVM Express standard is adding some new features. This talk will explain those features and how they address these issues.
