nimble storage architecture

First, the architecture of the InnoDB storage engine is simply presented in a single diagram.As can be seen, the InnoDB storage engine has multiple blocks of memory that make up a large pool of memory, primarily responsible for the following tasks: Maintain multiple internal data structures that all processes/threads need access to Cache data on disk

1.HDFS Storage Architecture(1) HDFS Architecture--File1) The file is cut into chunks (default size 64M), in blocks, each block has multiple copies stored on different machines, the number of copies can be specified at the time of file generation (silentRecognition 3)2) NameNode is the master node that stores metadata such as file name, file directory structure, f

The presence of FCoE in the storage field has caused a stir. In order to make it healthy and fast forward, the FCOE standard was introduced in June 09, which indicates that this technology will be more mature to the data Center storage transport protocol to lead the goal of the advance. Like many of the new technologies of the past, there are some positive fcoe, some people watching and others dismissive. H

The name of the alert file is in the format AlertSID.log. The location of the alert file is determined by the initialization parameter Background_dump_ DESC is specified.

It is believed that with the application architecture of the Internet technology being accepted by the traditional industry, object storage and Swift will be more and more widely concerned.From the OpenStack kilo version of the data, the swift community presents a diversity of features and is developing healthily.This article and the next two articles in this series will introduce the

In addition, the SQL Azure service Layer also monitors the storage nodes in the Platform Layer, completes down detection and recovery, Server Load balancer, and other overall control work.
