Hello, I am replacing my 72GB 15K disks with 140GB 15 disks to increase the space on my server's hard drive and I am installing a new operating system, Windows Server 2003 advanced. I want to build out the server with SQL best practices and make sure I do it right. My server has 6 internal disks and will have 4x146GB and 2x72GB drives. What is the best way to configure this server for optimal performance and best practices? If I went with my current configuration, here is what I would have: Use the 4x146GB disks as a RAID5 and the 2x72GB as RAID1. Build out a 292GB E: drive for the data files and backups. Build out a 72GB C: drive for the tempDB files, the OS and the paging file. My DB is SIMPLE recovery, so I do not have transaction logs growing. Here is another option that I am thinking of and my statistics needed for analysis: DB size - 17GB currently, may double in size in next year. Read/Write ratio = 2.7:1 Option#1: 3 separate RAID1 volumes. 146GB E: drive, 146GB F: drive and 72GB C: drive. The C: drive holds the tempDB files, the OS and paging file, The E: drive holds the data files and the F: drive holds the backups. One final very important question: When I build out the new server and restore the DB and tempDB, how do I change the drive and folder locations of those DB's? When I go into Enterprise Mgr. and click on the path, it says "A database file's physical location cannot be changed once the database file has been created." The same question goes for the DB file. When I build out my new server and install SQL EE, do I specify the locations of the files and then just do a restore of the backup there? I have had problems in the past trying to restore a DB where the old data files were on a different path? All input, guidance, help is greatly appreciated. Thanks!!
