The Conquest file system - life after disks
A.-I.A. Wang, Peter L. Reiher, Gerald J. Popek, Geoff Kuenning · 2005
Summary form only given. The Conquest file system is designed to provide a transition from disk- to persistent-RAM-based storage. Initially, we assume 2 to 4 Gbytes of persistent RAM and the popular single-user desktop environment. Unlike other memory file systems, Conquest can incrementally assume more responsibility for in-core storage as memory prices decline. The Conquest approach realizes most of the benefits of persistent-RAM-based file systems before persistent RAM becomes cheaply abundant. Conquest also benefits from the removal of disks as the primary storage by identifying disk-related complexities and isolating them from the critical path where possible. The Conquest prototype is operational under Linux 2.4.2. It is POSIX compliant and supports both in-core and on-disk storage.
