Recently storage vendors have advocated 'shingled media recording' devices. These drives are estimated to provide larger capacity than existing drives, but at the same time introduce a new access model. Hence it will not be possible to use them as all-purpose drives without modifications to the storage stack. For Linux there are two different proposals for handling these devices, either by using modified filesystems or by adding a device-mapper module.
This talk gives an overview about the technology behind shingled media recording and the proposed changes to the linux storage stack.
I will also present the results from running a modified stack on a pre-production device and its implications for further development.
