Standards are important, mainly to make things easy to find. We've got 60+ SQL Servers, 30 of which I manage. We have a standard hardware setup, 3 physical arrays min for all db servers. So we have
c: - OS and SQL
z: - SQL data and backups
y: - SQL Logs
arguably it should be different, but it works. We then have \mssql\data for all mdf files, \mssql\logs for ldfs, and \mssql\backup for backups with a sub for each db. \mssql\logs holds the logs and maint reports.
This is an easy way that ensures that we know where everything is. Need a report? map to \\servername\z$\mssql\logs and I've got reports. Easy to manage and find things.
