The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Is SQL Server Enterprise mandatory for clustering?

Asked by JoseParrot in Windows 2003 Server, MS SQL Server, SQL Server 2005

Tags: Microsoft, SQL Server, 2008 (downgrade to 2005), Cluster and log shipping

Our web site has one server with MS SQL Server 2003 Standard under Windows Server 2000 Standard .

Now we are to install a cluster for SQL Server with two nodes.
Each node is a Dell 1950 dual Xeon Quad.
We want an active/active cluster such that they divide the job in balance.

MS reseller says it must be SQL Server Enterprise to do that, but I found that SQL Server 2008 Standard, under Windows Server Enterprise 2003 does the clustering as we want. The limitations are that SQL Standard supports only two nodes (that's what we have!) and maximum of 4 processors (we have only two!). We need also to replicate to a third server, by using log shipping, at our Secondary (backup site).

We need that at Primary site one of the servers to be capable of run alone in case of failure of the companion node. In case of failure of the entire Primary site, we can start manually the Secondary.

At Primary site, Windows is Enterprise 2003 in both nodes, at Secondary, Windows is Standard 2003.
To avoid  SQL upgrade together with so many changes, we would like to downgrade the SQL 2008 license to 2005.

In few words:
Is SQL Server Enterprise mandatory to run the 2 node active/active cluster as we want? If not, is Standard enogh to clustering in active/passive mode?

Thanks in advance,
Jose
