Exchange 2013的Hyper-V物理集群 [英] Physical Cluster of Hyper-V for Exchange 2013

问题描述

嗨！

任何人都可以解释什么是Exchange 2013的最佳容错和负载平衡解决方案，以及物理Hyper-V之间的目的和区别是什么集群和Exchange DAG？

Can anybody explain what is the best fault tolerant and Load Balancing Solution for Exchange 2013 and what is the purpose of and difference between a Physical Hyper-V cluster and Exchange DAG?

谢谢。

推荐答案

您好，

为单个VM提供容错功能的虚拟机管理程序只能防止硬件故障。例如存储失败，或计算节点失败。然后，Hypervisor将虚拟机重新启动到正在使用的Hypervisor的
高可用性配置中的其他冗余硬件上。

A hypervisor providing fault tolerance for a single VM is only good to protect against hardware failure. for example storage fails, or a compute node fails. The Hypervisor will then bring the virtual machine back up on other redundant hardware within the high availability configuration of the Hypervisor in use.

如果您有一个Exchange框，则可以保护它反对硬件故障。它没有"保护它"是OS上的服务器应用程序或实际操作系统本身的问题。

If you have a single Exchange box, this protects it against hardware failure. What it doesnt' protect it against is issues with Server Applications on the OS, or the actual OS itself.

DAG将创建邮箱数据的多个副本，以防止该逻辑损坏，因此如果在操作系统或服务器应用程序中出现问题，可以对已知良好的工作DAG成员进行故障转移，并且可以继续提供可用性。

A DAG will create multiple copies of mailbox data, protecting against that logical corruption, so if an issue occurs within the OS or the Server application, failover can occur to a known good working DAG member and availability can continue.

这是对您的高级问题的高级答案。

This is a very high level answer to your high level question.

两者文章不是最近的，但应该让你了解你需要的理解水平。

Both articles are not recent, but should give you the insight to the level of understanding you need.
