The logical disk

Wiebren de Jonge, M. Frans Kaashoek, Wilson C. Hsieh
1993 Proceedings of the fourteenth ACM symposium on Operating systems principles - SOSP '93  
Abstract The Logical Disk (LD) defines a new interface to disk storage that separates file management and disk management by using logical block numbers and block lists.  ...  First, it leads to a file system structure that makes file systems easier to develop, maintain, and modify. Second, it makes file systems more flexible.  ...  We thank Eugene Belostotsky and Tom Pinckney for their work on the Mach implementation of LD.  ...

Toward optimizing disk-to-disk transfer on 100G networks

Eun-Sung Jung, Rajkumar Kettimuthu, Venkatram Vishwanath
2013 2013 IEEE International Conference on Advanced Networks and Telecommunications Systems (ANTS)  
In this paper, we first model all the system components involved in end-to-end data transfer as a graph.  ...  The experimental results show that our approach is several times faster than Globus Online -8x faster for datasets with many 10MB files and 4x faster for datasets with many 100MB files.  ...  For large files, the approach of splitting a file into multiple chunk and transferring the chunks simultaneously improve the performance.  ...

2006 Performance Evaluation Review  
As opposed to a traditional "smart" disk, an SDS has detailed knowledge of how the file system above is using the disk system, including information about the on-disk data structures of the file system  ...  We propose and evaluate the concept of a semantically-smart disk system (SDS).  ...  Finally, we thank the Computer Systems Lab for all of their tireless assistance in providing a terrific environment for computer science research.  ...

Magnetic disks for bulk storage

John M. Harker, Hsu Chang
1971 Proceedings of the November 16-18, 1971, fall joint computer conference on - AFIPS '71 (Fall)  
ACKNOWLEDGMENTS The authors gratefully acknowledge the helpful comments by R. Arnold, B. Beers, L. Comstock, F. Kurzweil, G. Santana and C. D. Mee.  ...  Consistent with the improved resolution of the recording system, the storage medium thickness has been reduced in successive improvements from 1000 microinches in the earliest disk files to below 100 microinches  ...  This approach, configured as a disk file, is attractive in concept. It shares with conventional disk equipment the simplicity of a homogeneous, stable, but reversible storage medium.  ...

Broadcast disks

Swarup Acharya, Rafael Alonso, Michael Franklin, Stanley Zdonik
1995 Proceedings of the 1995 ACM SIGMOD international conference on Management of data - SIGMOD '95  
We describe a new technique called "Broadcast Disks" for structuring the broadcast in a way that provides improved performance for non-uniformly accessed data.  ...  The Broadcast Disk superimposes multiple disks spinning at different speeds on a single broadcast channel -in effect creating an arbitrarily fine-grained memory hierarchy.  ...  Acknowledgements The authors would like to thank M. Ranganathan for providing them with a number of important insights into the properties of broadcast programs.  ...

Broadcast disks

Swarup Acharya, Rafael Alonso, Michael Franklin, Stanley Zdonik
1995 SIGMOD record  
We describe a new technique called "Broadcast Disks" for structuring the broadcast in a way that provides improved performance for non-unformly accessed data.  ...  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.  ...  Acknowledgements The authors would like to thank M. Ranganathan for providing them with a number of important insights into the properties of broadcast programs.  ...

Characterizing Disk Failures with Quantified Disk Degradation Signatures: An Early Experience

Song Huang, Song Fu, Quan Zhang, Weisong Shi
2015 2015 IEEE International Symposium on Workload Characterization  
In this paper, we present a systematic approach to provide a holistic and insightful view of disk failures. We study a large-scale storage system from a production data center.  ...  To the best of our knowledge, this is the first work that shows how to discover the categories of disk failures and characterize their degradation processes on a production data center.  ...  ACKNOWLEDGMENT The authors would like to thank the anonymous reviewers for their constructive comments and suggestions.  ...

Self-Learning Disk Scheduling

Yu Zhang, B. Bhargava
2009 IEEE Transactions on Knowledge and Data Engineering  
Experiments with real-world and synthetic workloads show that self-learning disk scheduling can adapt to a wide variety of workloads, file systems, disk systems, and user preferences.  ...  The performance of disk I/O schedulers is affected by many factors such as workloads, file systems, and disk systems.  ...  ACKNOWLEDGMENTS The authors wish to thank Kevin He at Cisco Systems Inc. for the helpful discussions.  ...

Haogang Chen, Daniel Ziegler, Tej Chajed, Adam Chlipala, M. Frans Kaashoek, Nickolai Zeldovich
2015 Proceedings of the 25th Symposium on Operating Systems Principles - SOSP '15  
To state FSCQ's theorems, this paper introduces the Crash Hoare logic (CHL), which extends traditional Hoare logic with a crash condition, a recovery procedure, and logical address spaces for specifying  ...  FSCQ provably avoids bugs that have plagued previous file systems, such as performing disk writes without sufficient barriers or forgetting to zero out directory blocks.  ...  Thanks also to the anonymous reviewers for their comments, and to our shepherd, Herbert Bos.

2013 Proceedings of the 27th international ACM conference on International conference on supercomputing - ICS '13  
Most notably, internal flash media bandwidth can be significantly (2-4× or more) higher than the external bandwidth with which the SSD is connected to a host system, and the higher internal bandwidth can  ...  Also, SSD bandwidth is projected to increase rapidly over time, creating a substantial energy cost for streaming of data to an external CPU for processing, which can be avoided via iSSD processing.  ...  Acknowledgment We thank the reviewers for their constructive comments, which helped improve the quality of this paper.  ...
