“…Antonelli and Honeyman describe the integrated mass storage system under consideration at CITI [Antonelli, 1993]. This system uses the mass store as a first-class data repository, with a disk-based file system and RAM serving as a cache of the mass store.…”

“…We are studying the organization and optimization of an integrated mass storage system based on a cache hierarchy [Antonelli, 1993], similar to that used by Plan 9 from Bell Labs [Pike, 1990, Quinlan, 1991. The system consists of a file system based on a mass store, e.g., magnetic tape or optical-based storage, attached to a file server with several gigabytes of disk cache and possibly hundreds of megabytes of RAM cache.…”

Delayed write in a multilevel file system cache hierarchy offers a way to improve performance in diverse client/server scenarios, such as integrating mass store into a distributed file system or providing distributed file system access over low-speed links. Using file system traces and cache simulations, we explore extensions and modifications to the traditional client caching model employed in such file systems as AFS, Sprite, and DFS.High cache hit rates at an intermediate cache server-a machine logically interposed between clients and servers that provides cached file service to the clients-combined with high client cache hit rates lend practicality to an integrated mass storage file system. In such a system, magnetic tape or optical-based mass storage devices may be used as a first-class data repository, fronted by disk and RAM caches to offer acceptable access times to the large, but slow, mass storage system.Similarly, a high cache hit rate is necessary for users accessing file systems via low-speed links, where a delayed write intermediate caching server can mediate traffic to make better use of available bandwidth. In an example taken from mobile computing, an intermediate server might be used as a docking station at a user's home. This arrangement would be convenient for users of mobile computers who upload large amounts of data generated while operating in disconnected mode. Simulations of delayed write caching strategies are applicable to both the mass storage and low-speed link scenarios .A. Schill et al. (eds.), Distributed Platforms

“…For example, [Anto93] describes the need for considering "cost of acquisition" for page replacement in deep-store file systems involving tertiary mass storage. This issue is also addressed forclient-server database systems in which a global memory hierarchy is created by allowing clients to obtain data from other clients that have that data cached~ran92].…”

This paper proposes the use of repetitive broadcast as a way of augmenting~he memory hierarchy of clients in an asyrnmdric communication environment.We describe a new technique called "Broadcast Disks" for structuring the broadcast in a way that provides improved performance for non-unformly accessed data.The Broadcast Disk superimposes multiple disks spinning at different speeds on a single broadcast channel-in e~ect creating an arbitrarily fine-grainedmemory hierarchy. In addition to proposing and defining the mechanism, a main result of this work is that exploiting the potential of the broadcast structure requires a reevaluation of basic cache managementpolicies.We examine several "pure" cache management policies and develop and measure implementable approximations to these policies. These results and others arepresented in a set of simulation studies that substantiates the basic idea and develops some of the intuitions required to design a particular broadcast program.
