Before you create a SQL Server 2000 failover cluster, you must configure Microsoft Cluster Service (MSCS) and use the Cluster Administrator in Microsoft Windows NT4.0 or Windows 2000 to create at least one cluster disk resource. Before running SQL Server Setup, note the location of the cluster drive in the Cluster Administrator because this information is required to create a new failover cluster. Only SQL

A failover cluster must meet certain requirements of the hardware, software, and network infrastructure, and it requires an administrative account with the appropriate domain permissions. Specifically as follows: (i) Hardware requirements for failover clusters In a failover cluster, the following hardware is required: (1) Server: It is recommended that you use

This topic explains how to use the Failover Cluster Management tool or Cluster.exe to evict a node from a Windows Server 2008 failover cluster. After a node is exited from the cluster, the node cannot host the clustered mailbox server. If, for any reason, you attempt to evict a node from a failover cluster, you can use the last procedure in this topic to force t

Problem Database mirroring has become a popular feature in SQL Server 2005. With the following simple steps, using the SQL Server Management suite or running some T-SQL commands, you can easily create database mirroring in one or more of your databases. One of the configuration options for database mirroring is high availability mode. With this option, the principal, mirror, and witness three servers are placed in the appropriate location. This is the only option that allows automatic troublesh

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 decided to put the cloud in a SQL Server to configure AlwaysOn, the idea is to add a node to the local SQL Server Failover cluster, then place the new home node in the Azure cloud a

, D: Virtual Machine to the host.A. Assume that we use three virtual machines as testing virtual machines, and run the loop script bat in the Virtual Machine. One or more of the three virtual machines will be migrated to other idle hosts.B. Suppose we set these three VMS to a test group and run the loop script bat in the VM, 3 Virtual opportunities are migrated to a host with a large amount of idle resources (including the local machine. This method applies when there is a Dongle)C. Suppose we s

Recently I changed my work. During work handover, I found that many esxi hosts do not have a password and all of them can only be cracked. To restore the password, perform the following operations: Use Linux to start a CD, such as an rhel5 installation CD or knoppix.

Thin provisioning (thin):Thin provisioning is the amount of storage that is used now, regardless of how large the disk is allocated, and how much is used. When the client has input and output, Vmkernel first allocates the required space and clear 0 operations, that is, if the use of thin configuration when there is IO need: Wait for the allocation of space and zeroing, these two steps to complete before the operation, for the IO called frequent applications such performance will be reduced, Alth
