The interface to storage devices has not changed for the last 40-50 years while the underlying physics and characteristics of magnetic storage systems are constantly changing. One example of a change that is looming before us is Shingled Magnetic Recording where disks are no longer physically able to randomly write. Emulating a random write device (the legacy interface) with the new physics is a huge amount of work for Seagate, but it also adds complexity for systems that use these devices because the storage have less deterministic performance.
What if we thought about a new interface that allowed the device to speak a language that is closer to what the application needs rather than what is compatible with the past?
Enter Kinetic, a new storage API for disk, flash and even RAM that is focused on Key/Value storage, not sector storage, that can use log structured and other techniques to give the applications a better API and allow the underlying device to do its job better. This API can be used to create scale out Distributed Hash Tables or Storage Systems that have Exabytes of storage with dramatically reduced infrastructure. Kinetic also attaches the devices with Ethernet to enable the disaggregation of computing.
This presentation will focus on the technical aspects of the Kinetic architecture to enable this vision.
