    Hi all,
    I have searched about with real application clustering in SQL Server latest version. In oracle there is a feature named RAC. and it provides high availability and Load Balancing together. I wonder how can i achive this (RAC feature in oracle) using SQL Server? coz SQL server uses windows clustering service and windows clustering service only provides high availability.
    Tnanks in advance

    Is this a generic comparison you want to know or something planned in your organisation?
    If you hover through the search engines there are multiple posts talking about pros and cons. In a nutshell what the application needs is scalability and load balancing in ther terms of RAC. There are valueable HA features avalable in SQL Server that will satisfy their HA / DR needs.
    The recovery of data depends on how the database is designed to handle the trnsactions and HA features http://www.microsoft.com/sql/technologies/highavailability/default.mspx and see RAC#s problem http://sqlblog.com/blogs/joe_chang/...inking-oracle-rac-think-again-whitepaper.aspx here. I see that peer-to-peer replication provides such an equivalent feature in SQL Server.

    Microsoft provide only High Availability and active/passive nodes,there is no active active and no load balancing,if you are trying to find a solution for Load Balancing then check NLB by microsoft and there are such other software base load balancing are available
