Data Storage

HSM Hierarchical Storage Management abbreviation, meaning "hierarchical storage management", refers to the data in the storage device to automatically migrate between the process. Hierarchical storage management can be stored at a lower cost, providing cost-effective storage services. But reduces the access performance. Even before there were vendors claiming that tiered storage management was dead. The reason is that HSM reduces overall storage performance, and today's mechanical hard disks and hard disk density solve all of today's storage problems. However, in recent years, with the large number ...

Research on cloud data storage security and Privacy protection strategy in IoT Environment Ming, familiarise, Liang Wenhui, Raihai, early morning IoT relies on cloud computing's powerful data-processing capabilities to implement information intelligence, and the current cloud computing management of data and services does not deserve the full trust of users. In order to ensure the accuracy and privacy of the data in the cloud, the paper puts forward a security and privacy protection strategy for cloud data storage under the environment of IoT environment. The experimental results show that the scheme is effective and flexible, and can resist byzantin ...

Do you need a lot of data to test your app performance? The easiest way to do this is to download data samples from the free data repository on the web. But the biggest drawback of this approach is that the data rarely has unique content and does not necessarily achieve the desired results. Here are more than 70 sites with free large data repositories available. Wikipedia:database: Provide free copies of all available content to interested users. Data can be obtained in multiple languages. Content can be downloaded together with pictures. Common crawl to establish and maintain a human being ...

In 2012, "big data" has been greatly developed. However, it is not hard to see from the perspective of the enterprises themselves, service prices and the limitation of "big data". Not everyone needs big data. From social media startups to New York's Central Park, big data analytics are spread across almost every company. This is an era of "big data" flooding. This is also evidenced by a recent report from Gartner, a well-known data analyst firm that shows that big data will drive $ 28 billion in global IT spending in 2012 and more than $ 230 billion in 2016. 230 ...

As social networking boomed, the Library of Congress had to deal with Twitter, which reached 133TB, and, thankfully, they had found a way to manage such data. As of now, the Library of Congress has kept the number of Twitter information has reached 170 billion, the volume of storage files to reach 133tb--because each piece of information has been shared and reproduced in this social network, the library's technical team needs to find a way to provide users with practical search solutions. In the current project report, the library Manager ...

According to Gartner's estimates, the number of consumers adopting cloud services will grow year after year, and by 2016 at least one-third of consumers will store their personal data in the cloud. Currently, personal data stored in the cloud only accounts for about 7%. However, Gartner researchers say future consumers' ability to capture data on cameras and camcorders on smartphones and tablets will be greatly enhanced, prompting the storage of data on local legacy devices such as PC hard disks Or external hard drive) outside of the development. At the same time, because allow ...

Research on cloud storage security technology based on HDFs Yu Qi Lingtie The security problems such as data leakage and data tampering existing in cloud storage technology, and combining with the characteristics of HDFS data integrality checking mechanism, this paper designs and realizes a data storage security technology scheme based on HDFS. To the user uploaded to the HDFS data file implementation of AES encryption, files in ciphertext form storage, and the application of RSA algorithm to protect the encryption of AES key, can effectively prevent the data in the transmission and storage process is leaked. The paper designs two storage formats of file cipher text and document plaintext based on HDFs.

Key-value Storage systems based on Linux kernel--kstore Shephandong key-value storage systems are widely used in a variety of internet services, but existing key-value storage systems are typically designed and implemented in user-state space, Because of frequent mode switching and context switching, the efficiency of the access interface and transaction processing is not high, especially in the high concurrency and low latency data storage requirements. To solve this problem, a kernel state Key-value storage System is presented--kstore: Provide kernel space ...

The Murdoch Children's Institute of Australia (MCRI) is trying to strengthen its data-storage capabilities because they are plagued by big data problems in the next generation of DNA sequencing technology.
