on these events. (4) The Action (action) event occurs when HA response, action is controlled by the shell, for example, when a node failure, the backup node will be programmed by the execution of the script to shut down or start the service. And then take over the resources of the failed node. Two, heartbeat composition (1) Heartbeat structure heartbeat1.x and 2.0.x version of the structure is very simple, each module is concentrated in the heartbeat, to the 3.0 version, the entire Heartbeat

Some knowledge about storageAccording to the different transmission protocols, the network card can be divided into three kinds, one is the Ethernet card, the second is the FC network card, the third is the iSCSI network card. Ethernet Card: The Scientific name Ethernet Adapter, the transmission protocol for the IP protocol, generally via fiber optic cable or twisted pair with Ethernet switch connection. The interface types are divided into optical and electrical ports. Optical ports ar

, thus forming a network of hardware devices. So, the fiber-optic network card is the name in the end is the fiber port HBA card? In fact, the fiber-optic network card that you often refer to is the HBA card in the Fibre Channel networks. Because of the different transmission protocol, the network card can be divided into three kinds, one is Ethernet cards, the other is FC network card, the third is iSCSI network card. • Ethernet Card: Scientific name Ethernet Adapter, transport protocol fo

From the data, we can see that the bandwidth of the Ethernet switch stack is dozens of times the speed of the switch port, which can effectively improve the network performance, when the number of ports that a single switch can provide is insufficient to meet the requirements of the network computer, more than two switches must provide the corresponding number of ports, which also involves the connection between switches. Basically, there are two ways to connect a vswitch: Ethernet switch stack

There is a binary file of about MB, which stores multiple JPG images. The file format is as follows: Unrelated data ZoneJpg image data ZoneUnrelated data ZoneJpg image data ZoneUnrelated data ZoneJpg image data Zone...... The starting mark of the jpg image is "FF D8 FF E0 00 10 4A", and the ending mark is "FF D9 ". What should I do if I want to read the jpg image data from this file and generate separate image files? I helped you write a program and tested a file containing only one picture.Int

This paper is a DSP and FPGA communication test based on chuanglong TL665xF-EasyEVM Development Board. The brief introduction of the TL665xF-EasyEV Development Board is as follows: consists of the core board + the bottom board. The core board DSP end adopts single-core tms320c6655 or dual-core tms320c6657 processor, FPGA end adopts Xilinx Artix-7 processor to realize heterogeneous multi-core processor architecture, DSP and FPGA internal through UPP, emif16, SRIo connection; The baseboard interfa

The Fiber jumper (also known as the optical fiber connector), which is the optical connector to access the optical module, also has many kinds, and can not be mutually used. The SFP module is connected to the LC fibre optic connector, while the GBIC is connected to the SC fiber optic connector. The following is a detailed description of several commonly used optical fiber connectors in Network engineering: ①FC Type fiber jumper: The external streng

It is to split the HA project into several relatively scattered projects, it is developed and maintained by different project teams.

heartbeat GUI tool can be used to connect any machine to a cluster. The cibadmin command must be used on the cluster node and is not limited to the DC node only. Policy Engine (PE) and Transition Engine (TE) need to change the cluster range whenever a coordinator is specified (rebuilding the new CIB ), the policy engine is used to compute the next State and (Resource) of a cluster to implement the list of operations required by the cluster. The commands calculated by the policy engine are then

available clusters are measured by system reliability (reliability) and maintainability (maintainability). In engineering, the reliability of the system is usually measured with mean time-free (MTTF), and the maintainability of the system is measured by mean time to repair (MTTR). The availability is then defined as: ha=mttf/(mttf+mttr) *100%Specific HA measurement criteria:99% downtime of less than 4 days a year99.9% downtime of less than 10 hours a year99.99% downtime of less than 1 hours a y

) Crm,cluster Resources ManagerThe cluster resource Manager relies on the underlying heartbeat information layer. This layer is because the non-ha_aware software itself does not have the ability to cluster high availability, only through the use of CRM to achieve, and if an application can use the underlying heartbeat information transfer layer function to complete the cluster transaction decision-making software is called Ha_aware.In this layer, in fact, there is a layer called
