We are investigating the potential for intermediate file servers to address scaling problems in increasingly large distributed file systems. To this end, we have run trace-driven simulations based on data from DEC-SRC and our own data collection to determine the potential of caching-only intermediate servers. The degree of sharing among clients is central(More)
distributed file system, distributed namespace, fault tolerance, Storage Area Network (SAN) A number of ongoing research projects follow a partition-based approach in order to achieve high scalability for access to the distributed storage service. These systems maintain a namespace that references objects distributed across multiple locations in the system.(More)
distributed file service, namespace, resource aggregation, manageability Monolithic file servers are limited by the power of an individual system. Cluster file servers are limited by resource sharing and recovery issues as the number of cluster nodes increases. DiFFS is a file service architecture that allows system resources to be added (or removed)(More)
Employing a delayed-write caching policy in a multilevel cache hierarchy may allow significant improvements in file system storage capacity as well as improving file system access over low-speed links. Cheap, high capacity mass storage systems can be viable as primary data repositories if front-end caching is used to mask the high access times typical of(More)
Advances in network monitoring protocols, such as SNMP and RMON, combined with their widespread availability from commercial vendors, has led to the development o f t o o l s that enable system administrators to eectively manage problem domains, such a s n e t w ork con-guration and troubleshooting. The abundance of monitoring and data-gathering tools(More)
