Detailed explanation of node behavior in cluster creation and cluster operations

Once the Cluster service is installed and running on the server, the server can join the cluster. Clustering can reduce the number of single points of failure and enable high availability of clustered resources.   The following sections briefly describe node behavior in cluster creation and cluster operations. Note: For information on installing the cluster server, see the Windows server http://www.aliyun.com/zixun/aggregation/19058.html >2003 product family ...

Strategies for delving into the Hadoop node deployment

Each http://www.aliyun.com/zixun/aggregation/14119.html ">hadoop cluster includes more than one node." These nodes can be grouped into several groups, such as the master group, the worker group, the client group, and so on.   The nodes in each group have different resource requirements, such as CPU, memory, storage. There is one or more virtual clusters (Cluster) in the Virtual Data Center (DataCenter) ...

Upgrade storage nodes to multi-node distributed, cloud storage innovation

From turtle bones to bamboo and then to paper, storage media such as magnetic tapes, disks, optical disks, hard disks, and data are constantly evolving. From small volume to large volume, storage technology is getting more and more advanced. However, these storage media are not perfect to solve the data security and long-lasting problems. Therefore, to create persistent storage based on these fragile storage media, you must rely on the appropriate policies and technologies. Traditional storage devices will adopt the scale-up architecture to solve the problem of storage scalability. However, this structure in dealing with massive data ...

A distributed algorithm for deeply analyzing NoSQL database

The scalability of the system is the main reason for promoting the development of NoSQL movement, including distributed system coordination, failover, resource management and many other features. That makes NoSQL sound like a big basket that can be stuffed with anything. Although the NoSQL movement does not bring fundamental technological changes to distributed data processing, it still leads to extensive research and practice on protocols and algorithms. It is through these attempts to gradually summarize some effective database construction methods. In this article, I will focus on the distributed features of the NoSQL database ...

Windows Server 2003 dual-node cluster installation Guide

During installation, other nodes are closed when certain nodes are installed. This step helps ensure that data on disks attached to the shared bus is not lost or compromised. Data loss or damage can occur when multiple nodes try to write to a disk that is not protected by the cluster software at the same time. Unlike http://www.aliyun.com/zixun/aggregation/11208.html ">microsoft Windows 2000 systems, Windo ...
