Multidimensional data organization and random access in large-scale DNA storage systems

With impressive physical density and molecular-scale coding capacity, DNA is a promising substrate for building long-lasting data archival storage systems. To retrieve data from DNA storage, recent implementations typically rely on large libraries of meticulously designed orthogonal PCR primers, which fundamentally limit the capacity and scalability of practical DNA storage. This work combines nested and semi-nested PCR to enable multidimensional data organization and random access in large DNA storage. Our strategy effectively pushes the limit of DNA storage capacity and dramatically reduces the number of orthogonal primers needed for efficient PCR random access. Our design uses only k⁎n primers to uniquely address nk data-encoding oligos. The architecture inherently supports various well-defined PCR random-access patterns that can be tailored to organize and preserve the underlying DNA-encoded data structures and relations in simple database-like formats such as rows, columns, tables, and blocks of data entries. We design in silico PCR experiments of a four-dimensional DNA storage to illustrate the mechanisms of sixteen different random-access patterns each requiring no more than two PCR reactions to selectively amplify a target dataset of various sizes. To better approximate the physical system, we formulate mathematical models based on empirical distributions to analyze the effect of pipetting, PCR bias, and PCR stochasticity on the performance of multidimensional data queries from large DNA storage.

One of the efforts to support the management of archives in the field of the General Bureau at the Secretariat General of the Ministry of Public Works and Public Housing of West Sumatra is to create an archival application system that can be operated via a computer network, with the aim of increasing the acceleration of the search service process for an archive. This research is: 1) To find out what are the obstacles faced in the archive management system in the General Bureau at the Secretariat General of the Ministry of Public Works and Public Housing of West Sumatra; 2) To find out what are the efforts made to overcome the obstacles in the archive management system in the field of the General Bureau at the Secretariat General of the Ministry of Public Works and Public Housing of West Sumatra; 3) To find out what are the efforts made to overcome the obstacles in the archive management system in the field of the General Bureau at the Secretariat General of the Ministry of Public Works and Public Housing of West Sumatra. This type of research is qualitative research. Qualitative research is research that intends to understand the phenomena experienced by research subjects (such as behavior, perception, action, etc.), holistically, and by means of descriptions in the form of words and language, in a specific natural and natural context. by utilizing various natural methods (Moleong, 2012;: 87). Informants are people who are used to provide information about the situation and conditions of the research background. So he continues to have a lot of experience in the research setting. As a team member with kindness, volunteering can provide views of values, attitudes and culture, which are the background for local research (Moleong; 2012: 90). The types of data are primary data and secondary data collected through interviews, observation and library research. The analysis technique used is qualitative analysis. The results of this study indicate that: recording or distribution of archives in the General Bureau of the Secretariat General of the Ministry of Public Works and Public Housing of West Sumatra Province uses several types, namely the Electronic Service Manuscript System (TNDE) and the outgoing mail agenda book. The conclusion that can be drawn is the dynamic archive management system in the field of the General Bureau at the Secretariat General of the Ministry of Public Works and Public Housing of West Sumatra Province in the aspects of creating and receiving archives, storing, maintaining, and shrinking, namely: in terms of creating and receiving archives, they have followed the existing archival provisions The most frequently created and received dynamic archives are correspondence records (letters). The archive storage system used at the General Bureau is the Electronic Service Manuscript Administration (TNDE) system. This TNDE system is so that letter data will be stored in a centralized database management system, making it easy to maintain data. The search for the TNDE system cannot be done automatically in the access feature in the system. For archival maintenance, the implementation of fumigation is carried out twice every year. In the context of shrinking the archives, there is an alternating dynamic archive assessment team. Archive shrinkage is in accordance with the Archive Retention Schedule (JRA), archives that have passed JRA will be immediately destroyed by burning. Suggestions include the implementation of a good archive management system at the Secretariat General of the Ministry of Public Works and Public Housing of West Sumatra, it should be equipped with supporting facilities and infrastructure.

Random access DNA memory using Boolean search in an archival file storage system.

DNA is an ultrahigh-density storage medium that could meet exponentially growing worldwide demand for archival data storage if DNA synthesis costs declined sufficiently and if random access of files within exabyte-to-yottabyte-scale DNA data pools were feasible. Here, we demonstrate a path to overcome the second barrier by encapsulating data-encoding DNA file sequences within impervious silica capsules that are surface labelled with single-stranded DNA barcodes. Barcodes are chosen to represent file metadata, enabling selection of sets of files with Boolean logic directly, without use of amplification. We demonstrate random access of image files from a prototypical 2-kilobyte image database using fluorescence sorting with selection sensitivity of one in 106 files, which thereby enables one in 106N selection capability using N optical channels. Our strategy thereby offers a scalable concept for random access of archival files in large-scale molecular datasets.

Training of alphanumeric filing system and electronic filing to teachers and administrative staffs of junior high school in Dolok Ilir

The archiving process uses a certain system in the preparation, maintenance of records so that they can be recovered quickly and precisely and easily for destruction of archives based on certain criteria. The archive itself has enormous benefits for educational organizations, because the archive is information on activities carried out by schools. Archives in schools need to be well managed, so that archives can be used effectively and efficiently and have good accessibility. The arrangement of archives usually has several problems including, documents cannot be recovered because they are lost, the number of documents is always increasing every day, the storage area for documents is too small compared to the number of documents, so the space is insufficient, not to mention the lack of staff capacity, and the system. The storage is not in accordance with the principles of archiving. For this reason, this service is aimed at providing knowledge and skills in arranging archives in accordance with RI archiving principles, namely using an alphanumeric archive storage system, through training followed by practice and evaluation. Adequate archive facilities and infrastructure are needed in schools for this training. After the dedication was carried out, teachers and administrative staff experienced an increase in knowledge and skills in compiling personal archives and schools got the facilities and infrastructure that supported archiving. Furthermore, an evaluation of the application of archiving in schools is carried out in order to determine its effectiveness in school management.

DNA Data Storage and Hybrid Molecular–Electronic Computing

Moore’s law may be slowing, but our ability to manipulate molecules is improving faster than ever. DNA could provide alternative substrates for computing and storage as existing ones approach physical limits. In this paper, we explore the implications of this trend in computer architecture. We present a computer systems perspective on molecular processing and storage, positing a hybrid molecular–electronic architecture that plays to the strengths of both domains. We cover the design and implementation of all stages of the pipeline: encoding, DNA synthesis, system integration with digital microfluidics, DNA sequencing (including emerging technologies such as nanopores), and decoding. We first draw on our experience designing a DNA-based archival storage system, which includes the largest demonstration to date of DNA digital data storage of over three billion nucleotides encoding over 400 MB of data. We then propose a more ambitious hybrid–electronic design that uses a molecular form of near-data processing for massive parallelism. We present a model that demonstrates the feasibility of these systems in the near future. We think the time is ripe to consider molecular storage seriously and explore system designs and architectural implications.

An OAIS-Based Hospital Information System on the Cloud: Analysis of a NoSQL Column-Oriented Approach.

The Open Archive Information System (OAIS) is a reference model for organizing people and resources in a system, and it is already adopted in care centers and medical systems to efficiently manage clinical data, medical personnel, and patients. Archival storage systems are typically implemented using traditional relational database systems, but the relation-oriented technology strongly limits the efficiency in the management of huge amount of patients' clinical data, especially in emerging cloud-based, that are distributed. In this paper, we present an OAIS healthcare architecture useful to manage a huge amount of HL7 clinical documents in a scalable way. Specifically, it is based on a NoSQL column-oriented Data Base Management System deployed in the cloud, thus to benefit from a big tables and wide rows available over a virtual distributed infrastructure. We developed a prototype of the proposed architecture at the IRCCS, and we evaluated its efficiency in a real case of study.

The MDS Queue: Analysing the Latency Performance of Erasure Codes

In order to scale economically, data centers are increasingly evolving their data storage methods from simple data replication to more powerful erasure codes, which provide the same level of reliability as replication, but at a significantly lower storage cost. In particular, it is well known that maximum-distance-separable (MDS) codes, such as Reed–Solomon codes, can achieve a target reliability with the maximum storage efficiency. While the use of codes for providing improved reliability in archival storage systems, where data is less frequently accessed (or so-called “cold data”), is well understood, the role of codes in storing more frequently accessed and active “hot data”, where latency is the key metric, is less clear. In this paper, we study data storage systems based on MDS codes through the lens of queueing theory, and term the queueing system arising under codes as an “MDS queue.” We provide lower and upper bounds on the average job latency for both centralized and decentralized versions of MDS queues. We also provide extensive simulations to corroborate our analysis as well as obtain additional insights.

Test Data Reader for Write Once, Read Forever (WORF) Interference Spectra Archival Media

We report on the test results of a recently fabricated data reader for our Write Once, Read Forever (WORF) high-density, very long-term archival data storage system. At the 2014 and 2015 IS&T Archiving conferences we described our technology and our progress establishing that multi-state data can be stored on monochromatic, dye-free, silver halide (AgX) media using our patented processes. WORF "freezes the wavelength" configuration of light within the media, which is restructured as a data constellation. Hitherto unreported chemical and optical phenomena are documented. WORF presents novel opportunities for security, encryption, data compression, and simple information recovery for the far future. It is known that AgX will last many centuries in ambient room temperature without continuous energy inputs or continual replication and authentication. This is an "existence proof" for the long-term archivability of data storage based on AgX chemistry.

A DNA-Based Archival Storage System

Demand for data storage is growing exponentially, but the capacity of existing storage media is not keeping up. Using DNA to archive data is an attractive possibility because it is extremely dense, with a raw limit of 1 exabyte/mm 3 (109 GB/mm 3 ), and long-lasting, with observed half-life of over 500 years. This paper presents an architecture for a DNA-based archival storage system. It is structured as a key-value store, and leverages common biochemical techniques to provide random access. We also propose a new encoding scheme that offers controllable redundancy, trading off reliability for density. We demonstrate feasibility, random access, and robustness of the proposed encoding with wet lab experiments involving 151 kB of synthesized DNA and a 42 kB random-access subset, and simulation experiments of larger sets calibrated to the wet lab experiments. Finally, we highlight trends in biotechnology that indicate the impending practicality of DNA storage for much larger datasets.

Measurement of slot misalignment in an optical archive data storage system using dual sensing

Optical disc cartridges for archive data storage are made up of multi-slot arrays, where each slot holds a disc. An archive data storage system should tolerate some level of misalignment between the disc and the cartridge slot. However, misalignment can lead to disc crashes against the slot walls or into other discs, and is often caused by poor positioning of the disc-transfer robot. Therefore, detecting misalignment is important to ensure the reliability of optical archive data storage systems. Here, we analyze the misalignment and propose a dual-sensing method based on a 4F imaging system. The method can simultaneously detect the top and bottom parts of the slots using only one detector.

National Center for Atmospheric Research storage accounting and analysis possibilities

SUMMARYWhile most high‐performance computing system operators diligently track computing usage and utilization on a job‐by‐job basis, far fewer sites have implemented mechanisms for tracking and accounting for usage of their storage systems. As we enter an era of larger and larger data holdings, the need to monitor, track, and analyze users' consumption of storage resources becomes more critical for planning, operating, and managing petascale storage environments. The National Center for Atmospheric Research has long had a formal accounting mechanism in place for its archival storage system and has recently extended a similar mechanism to its recently acquired 11‐PB disk resource. The collected data help National Center for Atmospheric Research's users manage their data holdings, provide administrators with reporting and analysis capabilities to guide the use and management of these vital resources, and offer necessary information to support data management policies.
