hot standby is the most important part of VMware vsphere 5.1, high availability is not unique to vsphere, enterprise use is high availability for service continuity and data security, HA is a group of ESXi server-based clustering features, The main purpose is to transfer the host in a timely manner to avoid prolonged downtime when the host machine running the VM fails. While the FT dual standby is to ensure that the maximum time the virtual machine d

Latch ha is an XLinux Latch series high-reliability server cluster system solution. Today, the smooth operation of various industries depends on computer systems. The ordering, distribution, customer service, financial settlement, insurance, and reservation of commodities all require highly reliable information service systems. This naturally requires the shorter the computer downtime, the better. Latch ha

OpenStack is an open source project designed to provide software for the building and management of public and private clouds. Its community is home to more than a few companies and 1350 developers, both of which use OpenStack as a common front-end for infrastructure as a service (IaaS) resources. The first task of the OpenStack project is to streamline the deployment of the cloud and bring it to a good scale. As a cloud computing IaaS layer de facto standard, OpenStack has a wide range of appli

If the primary server goes down, the loss is immeasurable. To ensure uninterrupted services on the master server, you need to implement redundancy on the server. Among the numerous solutions for implementing server redundancy, heartbeat provides us with a cheap and scalable high-availability cluster solution. We use heartbeat + drbd to create a high availability (HA) cluster service in Linux. if the master server goes down, the loss is immeasurable. T

We have been experimenting with the RedHat5 and 6 Versions of HA since January May of this year. I found the HA manual of version 6 on the Internet and found that although the project uses the dual-node mode most, if the dual-node mode is only for HA, A three-node or more arbitration disk is required. In addition, the HA
