Named volumes on raw flash, with wear levelling, power-cut safety and authenticated metadata.
Named volumes of logical blocks, created, resized and removed at run time. A block is replaced atomically, or appended to without an erase.
Logical and physical blocks
Erases are spread over the whole partition, on a budget the application chooses.
Wear levelling
Block updates, volume changes, erases and maintenance leave the old state or the new one.
Power loss
Headers and the volume table carry an AES-CMAC. Tampering is reported apart from damage, and the state callback lets the application detect a rollback.
Security
Adding the module, attaching, volumes, appends, key provisioning and maintenance on a work queue.
Examples
What each error and event means, what a power cut leaves behind, when to run maintenance, resources and limits.
