I'm getting ready to use SQL Server 2008's FileStream capability but I'm not sure if Classic ASP can read and write from SQL 2008 FileStream. We still have an old application we'd like to update to support File Uploads to database and would like to consider FileStream. If needed I can build a COM object via .NET to handle this but would...

I had some questions around the FILESTREAM capability of SQL Server 2008. What would the difference in performance be of returning a file streamed from SQL Server 2008 using the FILESTREAM capability vs. directly accessing the file from a shared directory? If 100 users requested 100 100Mb files (stored via FILESTREAM) within a 10 seco...
If I have a SQL Server 2008 database that uses FILESTREAM and stores 10 terabytes of files. Must all the files reside on the same physical box (requiring a 10+ terabyte server)? Or can I store 1 terabyte on one server, another terabyte on a second server, and so on? From what I have read it appears you can only store files on a single...
We are investigating the use of the Win32 streaming API to pull out files stored with the FILESTREAM capabilities in SQL 08. If a web application, sitting on the public side of the firewall uses the streaming API to pull back a file, what ports must be opened to make this happen? Also, are there any NTFS file/directory permission issue...
