File-Holding Appliances

File system virtual appliances

Implementing and maintaining file systems is painful. OS functionality is notoriously difficult to develop and debug, and file systems are more so than most because of their size and interactions with other OS components. In-kernel file systems must adhere to a large number of internal OS interfaces. Though difficult during initial file system development, these dependencies particularly compli...

File system virtual appliances: Third-party file system implementations without the pain

File system virtual appliances (FSVAs) address a major headache faced by third-party FS developers: OS version compatibility. By packaging their FS implementation in a VM, separate from the VM that runs user applications, they can avoid the need to provide an FS port for every kernel version and OS distribution. A small FS-agnostic proxy, maintained by the core OS developers, connects the FSVA ...

File System Virtual Appliances: Portable File System Implementations (CMU-PDL-09-102)

File system virtual appliances (FSVAs) address the portability headaches that plague file system (FS) developers. By packaging their FS implementation in a VM, separate from the VM that runs user applications, they can avoid the need to port the file system to each OS and OS version. A small FS-agnostic proxy, maintained by the core OS developers, connects the FSVA to whatever OS the user choos...
