High-performance network and channel-based storage

R.H. Katz
1992 Proceedings of the IEEE  
In the traditional mainframe-centered view of a computer system, storage devices are coupled to the system through complex hardware subsystems called I/O channels.  ...  A highly tuned remote file system on a 10 megabit (Mbit) per second Ethernet can provide perhaps 500K bytes per second to remote client applications.  ...  The VAXCluster is a collection of hardware and software services that closely couple together VAX computers and Hierarchical Storage Controllers (HSCs).  ...

DataMesh, house-building, and distributed systems technology

John Wilkes
1992 Proceedings of the 5th workshop on ACM SIGOPS European workshop Models and paradigms for distributed systems structuring - EW 5  
System design reconsidered as architecture The past several years have shown a steady increase in knowledge about building (distributed) computer systems.  ...  Consider the analogy of a distributed computer system as an ensemble of buildings. Rooms might represent address spaces; their occupants, threads; buildings the nodes of the distributed system.  ...  The former is a result of our desires to design a system capable of scaling up to a couple of hundred disk drives.  ...

Network attached storage architecture

Garth A. Gibson, Rodney Van Meter
2000 Communications of the ACM  
At its simplest, the difference between a NAS storage abstraction and a SAN storage abstraction is that NAS systems offer file system functionality to their clients and SAN systems do not.  ...  From the perspective of a datapath abstraction, there is little functional difference between the interfaces of a NAS system and those of a traditional local file system.  ...

Scalable coordination of a tightly-coupled service in the wide area

Kevin C. Webb, Bhanu C. Vattikonda, Kenneth Yocum, Alex C. Snoeren
2013 Proceedings of the First ACM SIGOPS Conference on Timely Results in Operating Systems - TRIOS '13  
In contrast, this work presents a way to scalably deploy tightlycoupled distributed systems that require significant coordination among a large number of nodes in the wide area.  ...  We characterize our abstraction in the context of a distributed rate limiting (DRL) service's deployment on a global testbed infrastructure.  ...  VAXclusters maintained a great deal of shared global state [18] , but assumed the nodes of the system were in close physical proximity, with relatively reliable, highspeed connectivity between them.  ...
