The layered caching is useful when your data can't be stored into the GPU because they're too big. Then, you really use the VBO as a buffer, you need several passes to transfer the content from the CPU to the GPU and to draw them. When your content can't be stored into the RAM, you can use the disk. Imagine that you have some mesh data about 100 times larger than the indirect NIO buffer you use to store the data in memory and your direct NIO buffer mapped on the GPU is 10 times smaller than your indirect NIO buffer, you'll have to perform 100 * 10 passes to draw your mesh with this layered caching.
