I think this question has been asked number of times. However, I am
looking for some specific information. Perhaps some of you can help
close the gap. Or perhaps you can point me towards right direction.

Perhaps this group can help me fill in ms-sqlserver related following
questions.

1. Do this database have data Clustering capabilities?
1a. If yes, what mechanism is used such as shared disk, share nothing,
etc.
2. Do these dB have Security features?
2a. If yes, what security features are supported? For instance do they
support encryption or SSL connection?
3. How does the database perform and what is the criteria for the
performance matrix?
4. Do they have inbuilt load balance capabilities?

I want to thank everyone for taking your time to read this
correspondence. I will also greatly appreciate your efforts in sharing
your thoughts.

Regards,
Manish

What sort of clustering do you have in mind? Clustering in MS SQL
Server is all about high availablility. That is two or more machines
that share disk. If one machine dies, another in the machine in the
cluster can take over very quickly.

I know that in other products, clustering is about scalinng out, but
MS SQL Server does not offering anything like that.

Yes, there are security features in MS SQL Server. :-)

You can encrypt data in SQL 2005, and you can also use SSL for
encrypting the connection.

I'm not sure that I understand these questions. But if they were asked
with a scale-out solution like Oracle's RAC in mind, they are not
applicable to SQL Server.

How does the database perform and what is the criteria for the
performance matrix? To clarify, how will one collect performance data
related to MS-SQLserver? What is the criteria for collecting such
data?

You can use performance counters, Profiler, query dynamic management views.

I'm afraid that I can't answer why you would like to collect some data.
Or I am not understanding your question.
