Setting Up A Raid 1

The primary purpose of using redundant array of independent disks (RAID) is to improve the disk http://www.aliyun.com/zixun/aggregation/14345.html "> Data processing capabilities and to provide redundancy." RAID can be set up either through the operating system (software RAID) or through a dedicated RAID control card without setting up the operating system (hardware RAID). This chapter will explain how to configure the Redhat/fedora Linux ...

This paper is an excerpt from the book "The Authoritative Guide to Hadoop", published by Tsinghua University Press, which is the author of Tom White, the School of Data Science and engineering, East China Normal University. This book begins with the origins of Hadoop, and integrates theory and practice to introduce Hadoop as an ideal tool for high-performance processing of massive datasets. The book consists of 16 chapters, 3 appendices, covering topics including: Haddoop;mapreduce;hadoop Distributed file system; Hadoop I/O, MapReduce application Open ...

IBM Infrastructure Cloud (IaaS) solution, can integrate service management platform to build public cloud/private cloud/mixed cloud, not only support web2.0 (work together, community), but also support including line trading (Bank, securities), Business processing (ERP, CRM), online analysis (risk assessment, strategy), 　　Other key business workload requirements such as high performance operations (weather forecasts, genetic research). IBM Blue Cloud architecture, IBM's cloud computing architecture, comes from the blue cloud solution. It is an enterprise-level cloud developed by IBM Cloud Computing Center ...

Cloud computing (Cloud Computing) is an internet-based Super computing model in which thousands of computers and servers are connected to a cloud of computers in remote data centers. The user uses the computer, the notebook, the handset and so on the way to pick up the data center, according to own demand carries on the computation. There is still no universally agreed definition of cloud computing. Combined with the above definition, we can sum up some essential features of cloud computing, that is, distributed computing and storage characteristics, high scalability, user-friendly, good management. 1 Cloud storage schema orange as storage node (Storag ...)

With the start of Apache Hadoop, the primary issue facing the growth of cloud customers is how to choose the right hardware for their new Hadoop cluster. Although Hadoop is designed to run on industry-standard hardware, it is as easy to come up with an ideal cluster configuration that does not want to provide a list of hardware specifications. Choosing the hardware to provide the best balance of performance and economy for a given load is the need to test and verify its effectiveness. (For example, IO dense ...

Most of the existing energy-saving technologies do not take into account the main factors of the growth of power demand, only consider how to reduce the overall energy costs. There are more effective ways for companies to conserve energy and improve efficiency at the data center. Fast-growing energy consumption can be addressed by efficiently storing data and reducing the number of machines and disks. 　　This strategy can not only reduce the complexity of the system, reduce costs, but also improve network efficiency and performance, so as to better respond to new business needs. 1. Consolidated server and Storage System server itself consumes half of the data center ...
