The following configuration is recommended as a minimal installation for a SQL Server database.
Pentium III-compatible processor or higher
512 MB RAM as a minimum; at least 1 GB is recommended (increase this based on the number of users, connections to the database, and volume)
3 GB disk space plus an additional 2 KB for each system record to be stored in the database (note that this is a conservative estimate per system record, assuming that most records do not contain complete data). This depends on the SQL Server environment you install.
VGA or higher resolution
Disk space recommendations do not take into account the volume and processing requirements or the number of users. These are minimal requirements to install a generic database. At a minimum, the empty database and the database software will require 1.6 GB of disk space.
