产品介绍 RoseHA Product Introduction

高可用系统解决方案 , 由两台服务器和一台共享存储设备组成主要硬件环境,通过 RoseHA 持续、稳定、高效的软件系统,实现两个节点的高可用功能。 The RoseHA high-availability system solution consists of two servers and a shared storage device to form the main hardware environment. Through RoseHA's continuous, stable, and efficient software system, high-availability functions of two nodes are realized. Rose 基于共享存储的高可用解决方案,实现企业关键业务 7×24 小时不间断运营,是企业最佳之选。 Using Rose 's high-availability solution based on shared storage to achieve 7 × 24 hours of uninterrupted operation of key business of the enterprise is the best choice for enterprises.

的工作原理 How RoseHA works

双机系统的两台服务器(主机)都与磁盘阵列(共享存储)系统连接,用户的操作系统、应用软件和 RoseHA 高可用软件分别安装在两台主机上,数据库等共享数据存放在存储系统上,两台主机之间通过私用心跳网络连接。 Both servers (hosts) of the RoseHA dual-system are connected to the disk array (shared storage) system. The user's operating system, application software, and RoseHA high-availability software are installed on the two hosts, and the shared data such as databases are stored in the storage system. The two hosts are connected through a private heartbeat network. RoseHA 软件开始监控系统,通过私用网络传递的心跳信息,每台主机上的 RoseHA 软件都可监控另一台主机的状态。 After the configured system host starts to work, RoseHA software starts to monitor the system. Through the heartbeat information transmitted through the private network, RoseHA software on each host can monitor the status of the other host. RoseHA 软件捕捉。 When the working host fails, the heartbeat information will change, and this change can be captured by RoseHA software through the private network . RoseHA 就会控制系统进行主机切换,即备份机启动和工作主机一样的应用程序接管工作主机的工作(包括提供 TCP/IP 网络服务、存储系统的存取等服务)并进行报警,提示管理人员对故障主机进行维修。 When this change is captured, RoseHA will control the system to switch hosts, that is, the backup machine starts the same application as the working host to take over the work of the working host (including providing TCP / IP network services, storage system access and other services) and An alarm is issued to remind the management personnel to repair the faulty host. RoseHA 的设定自动或手动再切换回来,也可以不切换,此时维修好的主机就作为备份机,双机系统继续工作。 After the repair is completed, you can switch back automatically or manually according to the settings of RoseHA , or you can not switch back. At this time, the repaired host will be used as the backup machine, and the dual system will continue to work.
实现容错功能的关键在于,对客户端来说主机是透明的,当系统发生错误而进行切换时,即主机的切换在客户端看来没有变化,所有基于主机的应用都仍然正常运行。 The key to RoseHA's implementation of fault tolerance is that the host is transparent to the client. When a system error occurs and the switch occurs, that is, the switch of the host does not appear to the client to change, and all host-based applications are still running normally. 采用了虚拟 IP 地址映射技术来实现此功能。 RoseHA uses virtual IP address mapping technology to achieve this function. The client communicates with the working host through the virtual address. The virtual address always points to the working host regardless of whether the system is switched. RoseHA 提供一个逻辑的虚拟地址,任何一个客户端需要请求服务时只需要使用这个虚拟地址。 When performing network services, RoseHA provides a logical virtual address, and any client only needs to use this virtual address when requesting services. In normal operation, the virtual address and network services are provided by the master server. RoseHA 会将虚拟地址转移到另外一台服务器的网卡上,继续提供网络服务。 When the primary server fails, RoseHA will transfer the virtual address to the network card of another server and continue to provide network services. After the switchover is complete, the system does not appear to the client to be faulty, and network services are still available. IP 地址外, HA 还可以提供虚拟的计算机别名供客户端访问。 In addition to IP addresses, HA can also provide virtual computer aliases for client access. For the database service, when a primary server fails, another server will automatically take over, and start the database and application at the same time, so that the user database can operate normally.

主要功能特点 RoseHA main features

简洁直观的管理方式 Simple and intuitive management
提供了友好直观的图形安装界面和监控管理界面。 RoseHA provides a friendly and intuitive graphical installation interface and monitoring management interface. Java Applet 管理界面,用户可以交互式地对集群系统进行配置、监控和管理,并可以利用 Applet 的网络特性,通过网络对系统进行远程管理,实时地显示出主机系统及服务的状态。 Through the intuitive and convenient Java Applet management interface, users can interactively configure, monitor and manage the cluster system, and can use Applet 's network features to remotely manage the system through the network, displaying the host system and services in real time. status.
灵活的高可用应用模式 Flexible and highly available application mode
支持 Active-Active 模式和 Active-Standby 模式。 RoseHA supports Active-Active mode and Active-Standby mode. active or standby ),指定要监控的服务和硬件部分,定义指定的服务发生故障后要采取的进一步行动(如是否重新启动该服务、允许的最大启动时间等)。 Users can specify the role of each server ( active or standby ), specify the services and hardware parts to be monitored, and define further actions to be taken after a specified service fails (such as whether to restart the service, the maximum allowed startup time, etc.) .
适应复杂网络环境 Adapt to complex network environments
在网络环境中,每个 IP 与唯一的 MAC 绑定在一起。 1. In a network environment, each IP is bound to a unique MAC . IP 在不同时刻绑定不同的 MAC 地址,导致跨网段通信出现问题。 However, under the traditional cluster structure, the active IP of the cluster will be bound to different MAC addresses at different times , causing cross-network segment communication problems. RoseHA 提供了支持虚拟 MAC 地址的功能,使集群环境 IP 地址实现与唯一 MAC 地址绑定。 In order for the cluster software to better support this network security level network environment, RoseHA provides the function of supporting virtual MAC addresses, enabling the cluster environment IP address to be bound to a unique MAC address.
支持 IPV4 网络通信协议以及未来适用的 IPV6 网络通信协议。 2. RoseHA supports IPV4 network communication protocol and future applicable IPV6 network communication protocol.
支持动态卷切换机制 Supports dynamic volume switching mechanism
支持 Windows 2008 R2 以后的平台上的动态卷,增强卷切换的效率。 1. Supports dynamic volumes on platforms after Windows 2008 R2 , enhancing the efficiency of volume switching.
支持 Linux 平台 LVM 卷设备切换。 2. Support Linux platform LVM volume device switching.
集群的容错可靠性 cluster fault tolerance reliability
集群具有容错可靠性, RoseHA 集群的拓扑包括两台服务器和一台磁盘阵列,硬件实现了容错可靠。 1. The RoseHA cluster has fault-tolerant reliability. The topology of the RoseHA cluster includes two servers and a disk array. The hardware achieves fault-tolerant and reliable performance.
具有两个核心进程,它们互相监控,如果其中一个进程失败,另一个进程会立即进行恢复,避免了 RoseHA 自身服务的单点故障。 2. RoseHA has two core processes, which monitor each other. If one process fails, the other process will immediately recover, avoiding a single point of failure in RoseHA's own service.
支持 Socket RS232 两种类型的心跳,配置多条心跳路径可以避免心跳的单点故障。 3. RoseHA supports two types of heartbeat: Socket and RS232 . Configuring multiple heartbeat paths can avoid single point of failure.
支持仲裁盘 4. Support arbitration
提供磁盘仲裁资源。 RoseHA provides disk arbitration resources. Even if all the communication between the cluster nodes is disconnected, the operating status of the cluster can be determined by arbitrating the resources to avoid resource competition between the cluster nodes.
丰富的附加功能 Various additional functions
Agent 程序,使服务监控更切实际,更加有效。 Provide different application-specific Agent programs to make service monitoring more practical and effective.
系统资源监控 System resource monitoring
        
CPU ,内存)。 In-depth and continuous monitoring of the system's operating status, intelligent analysis of system resource usage, and ensuring the health and stability of the system's resource environment (including CPU , memory).
集群环境监控 Cluster environment monitoring
RoseHA 集群服务通过 IP 网络链路互相通信,传递应用程序及主服务器运行状态信息。 The RoseHA cluster services on the active and standby nodes communicate with each other through the IP network link, passing information about the running status of the application and the active server.
RoseHA 心跳超时,所以建议管理员配置 2 条或 3 IP 网络作为私网心跳,避免因网络拥塞、服务器繁忙等非常规性网络或服务器故障,造成集群间通信不畅的情况发生。 When the cluster service cannot respond to the heartbeat sent by the other node within a preset time range due to network failures such as network congestion, network card failure, network operation service interruption, or server power failure, server downtime, system maintenance, etc. Information, may cause RoseHA heartbeat timeout, so it is recommended that the administrator configure two or three IP networks as private network heartbeats to avoid unconventional network or server failures caused by network congestion, server busy, etc., resulting in poor communication between clusters. The situation happened.
多样化的报警方式 Various alarm methods
针对各种意外提供了多种报警方式,如:在线日志,邮件通知,短信通知, SNMP 协议通知等,以便管理员及时监控管理集群。 RoseHA provides a variety of alarm methods for various accidents, such as online logs, email notifications, short message notifications, and SNMP protocol notifications, so that administrators can monitor and manage the cluster in a timely manner.
