Peeling Back the Layers of Storage - John Hawley, VMware

Linux has a myriad of storage options, and a number of layers that can be built one on top of another, to form some very robust, but potentially very complex, stacks that provide the entirety of the storage system. My intention is to work my way up from the most basic storage layer, physical storage, and explain what options there are from basic single disk and a file system type systems, to a full layered look at a system with raided disks, ssd caching, deduplication, all the way up through file systems in user space. This is specifically targeted as a high level overview of the systems involved, block, volume, and filesystems but it's also intended to go over some more complex systems, and how to achieve things like on the fly disk compression, deduplication, and give an overview of the different technologies available to achieve similar ends.
