if I want to create cluster how to create cluster for e.g sccm server so it needs to install on both server? or one server is is enough since it is shared location sccm 2012 server includes sql 2012 installation and sccm installation so it is possible to create cluster?

If I am reading that correctly I wouldn't use a cluster for Configuration Manager,

You question is a bit unclear but SCCM 2012 do support clustering for the site database only.

• Site system roles are not supported on an instance of a Windows Server cluster. The only exception to this is the site database server.

When you use a remote SQL Server, the instance of SQL Server used to host the site database can also be configured as a SQL Server failover cluster in a single instance cluster, or a multiple instance configuration. SQL Server cluster configurations that have multiple active nodes are supported for hosting the site database. The site database site system role is the only System Center 2012 Configuration Manager site system role supported on an instance of a Windows Server cluster. If you use a SQL Server cluster for the site database, you must add the computer account of the site server to the Local Administrators group of each Windows Server cluster node computer.

Thanks a lot sccm 2012 R2 clustering support for only for SQL data base I am right? not sccm 2012 R2 application for e.g I have 2 VMs hosted on2 ESXI box. I have used shared storage and created cluster installed SQL and SCCM on one server so same will be shows in other server? in other words how to setup sccm 2012 R2 clustering setup in simple setps

As stated you cannot cluster the ConfigMgr 2012 R2 application. You can cluster SQL - however this is a remote instance

Thanks kindly elaborate what is mean by "You can cluster SQL - however this is a remote instance" means install SQL server on shared storage and create SQL server between 2 VM's?

Yes. Standard SQL clustering.

By remote I mean that the SQL is not installed locally on the ConfigMgr site server.
