Chapter 7Failover Clustering and Migration Technologies

As previously discussed, when implementing virtualization, you consolidate your operating systems onto fewer pieces of hardware, effectively putting your eggs in a smaller number of baskets. It's therefore important that those baskets are as secure as possible and, in the event a basket breaks, there is another basket underneath to catch the eggs that fall.

Failover clustering provides resiliency for Windows services such as SQL, Exchange, file, and print, and now Hyper-V. By leveraging the failover cluster feature, Hyper-V servers can share storage resources such as LUNs on a SAN. But more important, clustering provides high availability from a node failure by moving virtual machines ...
