A comparative study of cloud storage structure model and cloud storage architecture The concept of Wang Hachen cloud storage is a new concept, which includes cluster computing, distributed File system and Grid computing technology. These heterogeneous storage systems form a virtual, huge storage system as a whole to provide data storage and business access functions together. This paper expounds the cloud storage structure model, and makes a comparative study on several typical cloud storage architectures. A comparative study of cloud storage structure model and cloud storage architecture

NoSQL storage scheme for large scale equipment monitoring data Zhongyu Huang Xiangdong Liu Huangyuxia Tian Wei Wang faced with massive data storage, fast read-write response, large-scale data analysis and other problems encountered in large-scale mechanical equipment monitoring data management, proposed to use based on NoSQL (not only SQL) Laud-ms System for monitoring data management of the storage architecture. A multi-column family free table model is designed, and the performance of reading and writing is analyzed and compared with the theory and experiment, which proves that this storage scheme can solve the storage problem of massive monitoring data and meet the ...

Dell and Hewlett-Packard were again on 27th, raising their bids for the US data storage provider 3PAR, which has risen to about $2 billion trillion. Dell took the lead on the day and said that 3PAR had accepted its new offer of $27 per share. The price was unchanged from HP's 26th offer, but Hewlett-Packard then announced that it would raise its offer to $30 a share, once again crimping Dell. 3PAR's shares were less than $10 per share before Dell initially announced the intent to buy it. HP's latest offer has reached more than 3 times times that number ...

Scache is a different method of PHP session data management. It provides a common key-value data cache for transient session data storage. Scache also provides a shared key space, shared counters, and simple caching capabilities. Scache distinguishes the other implementations from a tree-like key space, where people can easily manipulate the parts that are required to store session data and the data groups stored in the entire subtree that expire. Scache stores all session data inserts until the data is corrupted, thus reducing the redundant storage of the same data in other ...

From an article in the Openmymind blog, the author introduces two MongoDB monitoring gadgets, Mongospy and Mongowatch, which they write with Node.js, and then puts forward the idea of using compression to save space when storing text in MongoDB. These two gadgets are not very powerful and simple to implement, and if you can manipulate MongoDB in any language, believe you can write a similar thing. Mongospy: A MongoDB slow query to monitor ...

Often listen to entrepreneurs say their company will produce/record a lot of data every day, although they have not yet figured out how to use the data, but the data are saved first. They often say that through these data their products/services will be greatly improved, as if the data is the company's savior. This article does not want to discuss whether this view is correct or not, but would like to explain two common misconceptions about large data: First, data is not equal to information often people use data and information as synonyms. In fact, data refers to an original data point ...

From ancient to ancient times, people are always in the record, are in storage. From ancient stone carvings, bamboo slips, to cloth, paper, to compact discs and flash memory, storage has been becoming simpler and more massive. In the field of computers and Internet, storage has changed dramatically in just ten years. From small-capacity floppy disks to oversized removable hard disks, from portable high-capacity discs to smaller USB drives, from solid media to network-based cloud storage. Regardless of capacity, media or use, personal storage has a qualitative upgrade. In the past, we save data to disk, CD, hard disk ...
