Remember last year that you wrote a piece of Exchange Server 2007 SP1 CCR, but it's a Windows Server 2003-based platform. The failover cluster for Windows Server 2008 has been a number of projects, including SQL 2005, Exchange 200

If we want to ensure high availability of SQL Server, we can adopt a Failover cluster. The simplest failover cluster is two servers, one active server and the other standby

, data transmission and images are not involved. Instead, two or more computers are connected to each other in a shared external storage, usually a storage area network (SAN ). The database files are stored in the shared storage, and the SQL Server instances configured in the same settings run on the cluster nodes. Of all the nodes in the

We've written a lot of SQL Server-related articles in the near future, in order to improve the usability of the service, we think of the deployment AlwaysOn, the previous environment just deployed SQL Server Failover Cluster, so d

Received a mail consultation today how to implement a virtual machine affinity policy in Windows Server 2012, a technical home familiar with VMware vsphere Solutions is sure to be familiar with a dynamic migration strategy called DRS, The VM affinity policy can be configured to control two virtual machine applications running on different physical ESXi hosts. This function is still very practical, for example, if a virtual machine application runs a g

Myth #1: After a server failover, a running transaction continues to execute Of course it's wrong! Each failover is accompanied by some form of recovery. However, if a connection is disconnected because of a server or instance crash that occurs when a transaction is not being executed,

Misunderstanding #1: After server failover, ongoing transactions continue to be executed Of course this is wrong! Each failover is accompanied by some form of recovery. However, if the transaction being executed does not have a Commit, the connection is disconnected because the server or instance crashes,

. Applications that use failover clustering may require special coding to ensure that the failover process is transparent to the user when a failure occurs, and that the application is still available. For example, if you place time-outs and retries in the code used to save data to the database, you can ensure that the transaction will complete when the failover
