SDC2020: End To End Data Placement For Zoned Block Devices

End to End (E2E) Data Placement or intelligent placement of data onto media requires coordination between Applications, File System, and Zoned Block devices (ZBDs). If done correctly, E2E Data Placement with ZBDs will significantly reduce storage costs and improve application performance.
The talk will walk through state of the art database systems and define their data placement characteristics with the associated storage cost. Next, we discuss how E2E data placement can use the concept of a file to determine data associativity and efficiently store the file as zones on ZBDs. We will cover crucial ZBD metrics and present examples of how applications and file systems can be modified to be ZBD friendly. Methods to estimate the gains in throughput and storage cost reduction using E2E data placement and Zone Block devices will also be shown.

The attendees should leave the talk understanding how E2E data placement changes the role of Zoned Block Devices from storing LBAs to storing files. And how, by strategically mapping files, and it's data, as zones, one gain device capacity and reduces storage costs while improving both throughput and latency of your storage solution.
