The development of spark for a platform with considerable technical threshold and complexity, spark from the birth to the formal version of the maturity, the experience of such a short period of time, let people feel surprised. Spark was born in Amplab, Berkeley, in 2009, at the beginning of a research project at the University of Berkeley. 　　It was officially open source in 2010, and in 2013 became the Aparch Fund project, and in 2014 became the Aparch Fund's top project, the process less than five years time. Since spark from the University of Berkeley, make it ...

Research and realization of security data management system based on cloud the dream of the 祎 in this paper, a cryptographic index generation algorithm based on the underlying metadata set is proposed to encode the protected plaintext data. At the same time, based on the structural characteristics of relational database, the paper designs a database ciphertext storage model for storing ciphertext data and cipher index code. According to the query problem of database ciphertext data in Das model, this paper presents a query algorithm of ciphertext data based on filtering query technique. In the process of data query, the algorithm is first generated according to the user input of the clear text query conditions ...

The "3Par takeover Incident", which began in August this year, has been abuzz with the first head-on showdown between HP and two large companies in the takeover case. 　　After two weeks of intense competition, Hewlett-Packard finally bought 3Par companies at a high price of 2.35 billion dollars. HP and Dale 3Par to become the focus of the industry why do two of companies value a storage enterprise that is not big?

Two companies are willing to pay a large price to collect ...

The storage system is the core infrastructure of the IT environment in the data center, and it is the final carrier of data access. Storage in cloud computing, virtualization, large data and other related technologies have undergone a huge change, block storage, file storage, object storage support for a variety of data types of reading; Centralized storage is no longer the mainstream storage architecture of data center, storage access of massive data, need extensibility, 　　Highly scalable distributed storage architecture. In the new IT development process, data center construction has entered the era of cloud computing, enterprise IT storage environment can not be simple ...

Henry and I are working on an examination of the big data and its true meaning. Large data is a popular language. As with many popular words, the word "big data" is a bit overused, but it contains some real usability and technology. 　　We decided to analyze the big data on this topic and try to find out the authenticity of it and what they mean to storage solutions. Henry started this series with a good introduction. His definition of big data is the best definition I have ever seen. So I'm going to repeat this definition: Big data is turning data into information ...
