SnapDrive is a service that uses Virtual Local Disk (VLD) technology to present itself to SQL Server 2000 as a SAN-style, locally attached device. The filer requires a software license to enable the SnapDrive service. The license is installed on the filer at the factory per your order, so the initial setup of your filer does not involve entering license codes. You are provided with the appropriate license codes when your filer or software is shipped from the factory or when you are given instructions for obtaining the software over the Internet.
