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. Network Appliance provides you with the appropriate license codes when shipping you your filer or software from the factory, or when giving you instructions for obtaining the software over the Internet.
