Failover Link
Failover link is used to communicate each other's working status between devices, and the information passed on Failover link includes:
o Current status of the device (active and Standby)
O Power status (only based on dedicated failover

The transformation of Google architecture from failover system to multi-homed architectureRunning a single data center is difficult, so switch to a dual datacenter if you need to support multiple data centers in different geographies. Google has a thoughtful, thought-provoking paper that describes the process-"large-scale high availability: Building Google's advertising data infrastructure."The main idea is that a typical
Using shared folders to implement the quorum disk for a failover clusterIn the previous blog post we've introduced how to build a Distributed File System (DFS), and we've explained how to configure DFS to be highly available, so today's blog post We'll show you how to use DFS to make our Windows cluster arbitration disk.Don't know if you know me in front of the blog post Why do I want to be highly available for DFS configuration, in fact, I configure
Before leader triggers failover, wait a few seconds (then 0~5) for other Sentinel instances to prepare and adjust. If all is well, then leader needs to start upgrading a salve to master, which must be in a good state (not in the Sdown/odown state) and with the lowest weight value (redis.conf), when Master is confirmed, Start failoverA) "+failover-triggered": Leader began
15.7 multi-subnet failover clusters15.7.1 Multi-subnetSQL Server 2012 introduces a stretch cluster set (Stretch Clusters) that enables clustering across geographically dispersed sites. Each failover cluster node is connected to a different subnet (or subnet group) and is therefore referred to as a multi-subnet failover cluster.In a multi-subnet cluster, there is
The impact of messages on SOA
In the first part of the message, I wrote about many long-standing best practices from the point-to-point messaging architecture to the service-oriented development requirements update message domain. Here, we will consider a case study to understand the migration, failover, and extension of the queue manager, and the impact on naming conventions, tools, management processes, and operations when considering these activit
