The WebSphere application server clustering mechanism allows a complete application server (including EJB container, EJBs, Web containers, Web modules, and servlets) to be copied as a cluster.
WebSphereApplicationServer集群机制允许将整个应用服务器(包括ejb容器、EJB、web容器、Web模块和Servlet)作为一个集群进行复制。
If one of the servers in the high availability cluster was to fail, then clustering software would transfer the failed server's workload to a surviving server in the cluster.
如果高可用性集群中的某一个服务器出现故障，那么集群软件将把出故障的服务器上的工作负载转移到集群中仍然正常的一个服务器上。
If one of the servers in the cluster was to fail, then clustering software would transfer that failed server's workload to a surviving server in the cluster.
如果集群中的某一个服务器出现故障，那么集群软件将把出故障的服务器上的工作负载转移到集群中仍然正常的一个服务器上。
The load that clustering adds to a server is proportional to disk write rates due to the workload on the server.
受到服务器工作负载的影响，集群向服务器增加的负载与磁盘读比率是成比例的。
GlassFish Clustering is centered around an administrative domain which can then create a single server instance or clusters with multiple instances spread across distributed machines.
GlassFish集群以管理域为中心，然后可以创建单独的服务器实例或是使用遍布在分布式机器上的多个实例创建集群。
Ideally, you would want the router to follow an appropriate load balancing strategy and also maintain the required server affinity. Thus, the quintessence of super clustering is to.
理想情况下，您希望路由器执行一个合理的负载平衡策略，同时维护必要的服务器亲缘性。
Vertical clustering: Running multiple nodes or instances of an application server on the same host.
垂直集群：在同一主机上运行应用服务器的多个节点或实例。
You reap the benefits of clustering and load balancing from one single installation of the server, improving scalability and ensuring high availability in case one instance crashes or hangs.
您只需要安装一个服务器，就可以获得集群和负载平衡的优点，从而在某个实例崩溃或者挂起的情况下，改善可伸缩性，并确保高可用性。
Horizontal clustering: Running multiple nodes or instances of an application server on different hosts.
水平集群：在不同的主机上运行应用服务器的多个节点或实例。
This function is enabled by features of the application server to support dynamic clustering techniques.
这个功能是由支持动态集群技术的应用程序服务器的特性实现的。
Another area related to clustering in an application server is caching.
与应用服务器中的集群有关的另一个领域是缓存。
Horizontal clustering - Various instances of the server or cluster members are on different nodes.
水平集群化—服务器或者集群成员的不同实例处于不同的节点。
The new messaging engine takes full advantage of the clustering and load-balancing features of the application server.
新的消息传递引擎充分利用了应用程序服务器的集群以及负载平衡的特性。
This default setting was appropriate for "the average server" when clustering was first shipped several years ago, but it is too large for the current generation of servers.
在几年以前开始附带集群时，该默认设置适用于一般的服务器，但是对于现代的服务器，该值太大了。
The main reasons for clustering an application server are to increase its performance and stability.
把应用服务器进行集群化的主要原因是提升它的性能和可用性。
It would normally be better, though, to use MQ clustering techniques to achieve this, giving each application server its own queue manager.
但是在通常情况下，一种更好的解决此问题的方法是使用MQ集群技术，这将为每个应用程序服务器提供自己的队列管理器。
For super clustering, the advantage of using a proxy server in this configuration instead of the HTTP plug-in router is that there is no need to manually edit any static routing information.
对于超级集群，与使用HTTP插件路由器相比，使用代理服务器的优势在于不需要手动编辑任何静态路由信息。
How clustering affects the load on a server?
