Introduction of Lifekeeper Multi-platform fault-tolerant cluster software

American Steeleye Company's lifehttp://www.aliyun.com/zixun/aggregation/19458.html ">keeper is a kind of support for a variety of soft (WINDOWNT, Windows2000, A variety of Linux and other hardware platform high-performance fault-tolerant software, can support up to 16 server clusters. Lifekeeper software originated in NCR, USA and the famous At&t Bell Labs. For enterprises, banks, Governments and other information services, business services, government services, such as the provision of high availability solutions.





Lifekeeper is a highly available fault tolerant clustering software that runs on NT, Windows 2000, Linux, and NCR UNIX platforms. It also supports pure software mirroring and shared disk array cabinets, and supports remote disaster real-time replication backup and recovery system. Keep users ' servers, operating systems, database systems, and critical data and applications up to 7 days of uninterrupted x24 hours, providing 99.99% of high availability. The software includes core parts and some ark for different applications.




Key features of
Lifekeeper





1. Without adding any additional hardware investment, the Pure software method realizes the dual-computer fault-tolerant, and has no hardware configuration requirements for the standby machine.


　　


2. Supports application layer thermal recovery for a variety of systems, such as notes, Exchange, SQL Server, Sybase, Informix, Oracle, SAP, and more.


　　


3. Is the world's first operating system based on NT fault tolerant software and support Linux platform. Support for remote disaster backups.


　　


4. The support of shared disk array cabinets and extended mirrors are two ways to provide users with the flexibility to choose, but also to adapt to a variety of models, network structure, software platform and application system.


　　


5. Lifekeeper in any mode of extended mirror or shared disk array, the two servers can run different applications and heat backup mutually, that is, realize dual active operation mode.


　　


6. When using shared disk array cabinets, you can support up to 16 nodes, much larger than the number of 2 nodes supported by other similar systems.


　　


7. Maximize the protection of client application continuity. User's hardware resources (such as network card), software resources (such as NT operating system, database management system, database application system, e-mail system, etc.) can be under the protection of lifekeeper, when these protected resources appear technical failure, lifekeeper can implement system resource switching at any time. In this way, Lifekeeper truly realizes the online hot switching on the system and the application layer when the user hardware or software resources fail.


　　


8. Lifekeeper occupies very little system resources, does not increase network load, and does not disturb any specific application system operations.


　　


9. Lifekeeper really realize unattended, fully automatic application resource switching, and graphical interface operation, simple and convenient.


　　


10. Since put into use, has experienced a large number of transaction peaks of the actual test, its implementation efficiency is very high and running very stable and reliable, the global market share first.
