Abstract
Customers of SSDs have very different requirements. While a single uniform space of non-volatile storage media may satisfy some, others require independent areas with performance isolation. Still others may require a small amount of low-latency storage and a much larger amount of higher-latency storage. To enable a single SSD type to be configured by the customer to satisfy their particular requirements, NVM express has defined a mechanism to configure non-volatile media in not just SSDs but also in storage arrays.
