NVMe Management Interface – Part Four

By |2018-12-07T14:30:29+00:00December 7th, 2018|Media Coverage|

NVMe Management Interface Architectural Overview NVMeTM Management Interface (NVMe-MITM) is targeted at enterprise and hyperscale applications and currently not at client applications. The use cases include: Inventorying (Asset Management), Health Monitoring (Identify bad drives), Wear Monitoring (Replace drives nearing wear-out), Temperature Monitoring (Fan throttling), Power Monitoring and configuration, Configuring (format drives, crypto erase), Change Management (update [...]
