There are two parts to 3DM: a process, that runs in the background on the computer where you have installed your 3ware controller, and a web application that can be used to access it. 3DM runs as a service under Microsoft Windows, and as a daemon under Linux and FreeBSD. When the 3DM process is running, you can use your browser to go to 3DM application pages, where you can view status information about the controller and RAID units, create RAID units, and perform other administrative and maintenance tasks locally or remotely.
Two levels of access to 3DM are provided: user and administrator. Users have view-only access, and can check the status of drives and units. Administrators can view and make changes, using 3DM to configure RAID units and designate hot spares, and to perform maintenance tasks on RAID units.
