Ha Cluster Configuration

Introduction to Namenode in Hadoop is like the heart of a human being, and it's important not to stop working. In the HADOOP1 era, there was only one namenode. If the Namenode data is missing or does not work, the entire cluster cannot be recovered. This is a single point in the Hadoop1 and a hadoop1 unreliable performance, as shown in Figure 1. 　　HADOOP2 solved the problem. The high reliability of HDFs in hadoop2.2.0 means that you can start 2 name ...

Cluster is a hot topic, in the enterprise more and more application of Linux operating system to provide mail, Web, file storage, database and other services, with the growing application of Linux, high availability and http://www.aliyun.com/zixun/aggregation/ 13996.html "> Load balanced Linux cluster is also developing gradually in the enterprise. The low cost, high performance and high scalability of the Linux platform enable the Linux cluster to meet at a low price ...

This recipe provides an example of how to set up a FortiGate for redundant Internet connectivity using SD-WAN and then convert this single FortiGate into an FGCP HA cluster of two FortiGates.

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 ...

This recipe describes how to add a third FortiGate to an already established FGCP cluster (the cluster from High Availability with FGCP) and configure active-active HA.

Primecluster has a history of nearly 20 years, with Fujitsu's Siemens computer company in the global business, across various industries and fields, in Europe, the Middle East, Africa and Asia have a large number of http://www.aliyun.com/zixun/ 　　Aggregation/7565.html "> Success stories. Supports multi-platform ――primecluster support Linux/intel and SOLARIS/SPARC platforms. It maintains at the user level ...

In this recipe you set up a FortiGate Clustering Protocol (FGCP) virtual clustering configuration with four FortiGates to provide redundancy and failover protection for two networks.

Simply put, a cluster (cluster) is a group of computers that provide users with a set of network resources as a whole. These individual computer systems are the nodes (node) of the cluster. An ideal cluster is that the user never realizes the nodes at the bottom of the cluster system, in their view, the cluster is a system, not multiple computer systems.     And the administrators of the cluster system can add and revise the nodes of the cluster system at will. Below on the server commonly used three cluster software to do a comparative analysis of the introduction: 1 ...

This article shows how to setup an active-passive session-aware load balancing cluster (SLBC) consisting of two FortiGate-5000 chassis, four FortiController-5103Bs two in each chassis, and six FortiGate-5001Bs acting as workers, three in each chassis.

In this recipe you set up a FortiGate Clustering Protocol (FGCP) virtual clustering configuration with two FortiGates to provide redundancy and failover protection for two networks.
