UHA

In recent years, with the extensive application of enterprise information systems and in-depth development of the user's core applications more and more, by the upgrade, maintenance and repair plans downtime or human error, Of the system downtime to the enterprise has brought incalculable losses.

  • Scope of application:

    UIT launched UHA high availability software to manage the complex enterprise internal system, automatic detection system failure, the business will be switched to the standby server in a timely manner to ensure business continuity.

In recent years, with the wide application and development of the enterprise information system, the user's core application number increasing, system downtime caused by upgrading, maintenance and repair plan downtime or human error, fault, power failure, disaster accidents such as the enterprises to bring immeasurable losses. Users need more and more strong business continuity, not only in the key business, but also in improving the service server availability and database system data security, and so on, the demand is also increasing. At the same time, in recent years, the frequent occurrence of natural calamities and man-made misfortunes, make more users aware of the necessity of the application of remote disaster recovery. UIT launched UHA high availability software to manage the complex enterprise internal system, automatic detection system failure, the business will be switched to the standby server in a timely manner to ensure business continuity.



更高可用性

       有效應對更多故障,實現360°故障檢測

基本故障監測:OS故障、網絡故障、硬件故障、服務器宕機

高級故障監測:磁盤故障、軟件異常(包括應用和服務進程)、異常高負荷及因維護性而導致的停機等

       更快速實現切換,保證系統可用性

領先的差分鏡像技術,使鏡像型應用在故障恢復時僅對主備服務器間磁盤差分數據進行同步和恢復,大幅縮短恢復時間,提高鏡像集群性能

 


更高靈活性

       基於用戶資源,構建不同級別高可用解決方案

       共享型

兩台以上服務器共享磁盤陣列方式

適用於大規模的集群系統(2~32節點)

支持FC SAN,IP SAN等多種存儲架構

       鏡像型

通過本地或遠程的磁盤鏡像方式實現數據同步

適用於小規模、低成本的集群系統

支持3節點以上的多點鏡像

       共享+鏡像型

實現本地共享和本地鏡像共存於一個集群的應用場景

重要數據可存放於鏡像盤中,以保證數據實現物理備份,避免單點故障

       混合型

本地共享型和遠程鏡像共存的方式,保證業務萬無一失

支持磁盤陣列間的鏡像

可實現遠程應用容災方案

 


基於用戶資源,構建多種高可用模式 

       多台服務器間的一備一、一備N、N備一、N備N等多種工作模式

 

       服務器節點最多可擴展至32個,更好的保證用戶業務連續性


遠程應用容災 

       基於遠程鏡像的異地應用容災,不僅能夠異地鏡像業務數據,還可對軟硬件資源進行監視

       獨創的混合型集群可以實現同步/異步鏡像,當主節點發生故障時,能夠在鏡像節點恢復業務

 


遠程應用容災

更高管理性

        支持網卡(私網/公網)、COM口、磁盤心跳等多種心跳監測方式,時刻監視系統健康狀態

 

       獨特的內核空間心跳探測技術,保證心跳探測不受系統負荷影響 

       故障報警功能,可通過電子郵件或手機短訊向管理者發送故障通知 

       跨平台遠程管理,不需安裝客戶端程序,可在任意一台裝有Java運行環境的機器上利用瀏覽器進行系統監控、維護和配置操作,極大的方便了系統管理員的操作和管理
