[MS SQL Server] #Files and FILEGROUPS

[MS SQL Server] #Files and FILEGROUPS

#Files and FILEGROUPS

Posted: 06 Mar 2013 07:49 PM PST

Hi,In an 8 CORE machine with 3 RAID10 (data files, log files and tempdb) what's the appropriate number of files or filegroups for a database with lots of users and IO? I saw a SQLPass presentation where it said 1 file for 4 CORES..If a database has 2 files and since the files are on the same RAID set is it worth creating also 2 FILEGROUPS (one for each data file) or the porpoise of FILEGROUPS is to put "sensible" data on one and not so sensible data on another so the 1st one has backups more frequently?Thanks,Pedro

Install SQL server from command line and configuration files

Posted: 07 Mar 2013 05:07 AM PST

I would like to try use command line and configutionfile to install SQL server.I read I should put the commandline fine in the root of installation file.We have a shared folder that has all the installation file on the network, I don't have write permission on that folder. I don't want to copy those installation files to my local too, then what other options can I do?I tried to add in the command line to change the directory to the installation files location at start, but since it is a shared directory, I got an error: CMD does not support UNC paths as current directories.Any recommendations?Thanks
