A Metadata Kernel for Electronic Permanence

John A. Kunze
2001 International Conference on Dublin Core and Metadata Applications  
It starts with the Dublin Core consensus and distills out a subset of four semantic buckets − a metadata kernel − that balances the needs for adequate identification of persistent objects and for low cost  ...  This paper presents a streamlined metadata record format designed to support the permanence of network discoverable objects.  ...  The author is grateful for Jane Greenberg's helpful comments.  ...

Digital Object Identifiers and Their Use in Libraries

Jue Wang
2007 Serials review  
Answers for a number of basic questions about the identified resource (kernel metadata elements, a minimum level of publicly available structured metadata) should be known by the RA at the time the DOI  ...  Therefore when the publishers register DOIs, they also register kernel metadata that associated with the DOIs.  ...  Even though some issues are still around DOI, such as copyrights protection for DOI; metadata standards via assigning DOIs and missing links, we should continue to educate and market on DOI and to encourage  ...

NVMFS: A hybrid file system for improving random write in nand-flash SSD

Sheng Qiu, A. L. Narasimha Reddy
2013 2013 IEEE 29th Symposium on Mass Storage Systems and Technologies (MSST)  
We have implemented a prototype NVMFS within a Linux Kernel and compared with several modern file systems such as ext3, btrfs and NILFS2.  ...  However, the random write performance is still a concern for SSDs. Random writes could also result in lower lifetimes for SSDs.  ...  We use the higher performance NVRAM as both a cache and permanent space for data.  ...

Performance evaluation of distributed file systems for the phase-II upgrade of the ATLAS experiment at CERN

Adam Abed Abud, Fabrice Le Goff, Giuseppe Avolio
2020 Journal of Physics, Conference Series  
A possible implementation for such a design is based on distributed file systems (DFS) which are becoming ubiquitous among the big data industry.  ...  This will create a harsher radiation environment and higher detector occupancy.  ...  Therefore, it is worth selecting technologies that do not use dedicated metadata servers such as for example key-value stores.  ...

Hardware-assisted Trusted Memory Disaggregation for Secure Far Memory [article]

Taekyung Heo, Seunghyo Kang, Sanghyeon Lee, Soojin Hwang, Jaehyuk Huh
2021 arXiv   pre-print
It allows a node to use part of memory in remote nodes in the same cluster.  ...  With its own networks, a set of FPGA-based engines form a trusted memory disaggregation system, which is isolated from the privileged software of each participating node.  ...  Reprogramming of an FPGA can be permanently blocked by disabling a JTAG port. A JTAG port can be disabled by blowing up a corresponding electronic FUSE (eFUSE).  ...

End-to-end Data Integrity for File Systems: A ZFS Case Study

Yupu Zhang, Abhishek Rajimwale, Andrea C. Arpaci-Dusseau, Remzi H. Arpaci-Dusseau
2010 USENIX Conference on File and Storage Technologies  
This section provides the motivation for our study by describing how potent the problem of disk and memory corruptions is to file system data integrity.  ...  We present a study of the effects of disk and memory corruption on file system data integrity. Our analysis focuses on Sun's ZFS, a modern commercial offering with numerous reliability mechanisms.  ...  We thank Asim Kadav for his initial work on ZFS on-disk fault injection. We also thank the members of the ADSL research group for their insightful comments.  ...

ScaleFFS

Dawoon Jung, Jaegeuk Kim, Jin-Soo Kim, Joonwon Lee
2008 ACM Transactions on Multimedia Computing, Communications, and Applications (TOMCCAP)  
In this article, we design and implement a scalable flash file system, called ScaleFFS, for mobile multimedia systems.  ...  A key issue in designing storage systems for mobile multimedia systems is handling large-capacity storage media and numerous large files with limited resources such as memory.  ...  On the other hand, JFFS2 permanently keeps all metadata of files in memory while the files are being used by a user or the kernel.  ...

Operating system level data tiering using online workload characterization

Reza Salkhordeh, Hossein Asadi, Shahriar Ebrahimi
2015 Journal of Supercomputing
