xv6 uses an inode based filesystem where each inode contains 12 direct data block pointers and 1 single indirect block pointer, where a block "pointer" is just a 4-byte disk block number (indexed from the first sector on the drive). Because a block is 512 bytes large, the indirect block can hold an additional 128 block numbers, resulting in a ...

xv6 is a nifty operating system that is essentially a reimplementation of Sixth Edition Unix that, unlike most of the huge montholithic Linux or BSD distributions that you'd run on your workstation or server, is simple enough to be used as a learning tool.
