Abstract
We present the design of AppNVM, a software-defined, application-driven solid state drive (SSD) inspired by Software-Defined Networking. AppNVM exposes an application-defined interface without sacrificing performance by separating the
data plane from the control plane. Applications control App-NVM SSDs by installing rules, which define (i) the logical address space exposed to the application, and (ii) how application requests are handled. A controller then transforms those rules and installs them onto the device, enforcing permissions and global policies such as wear-leveling and garbage collection when needed. Once rules are set up, the application sends requests directly to the device. By separating the data plane from the control plane, AppNVM scales to high-performance million-IOPS devices and beyond. In this paper, we describe the
architecture of AppNVM and discuss technical challenges.
