3DM2 is a service under Windows, or a daemon under FreeBSD, Linux, OpenSolaris, Mac OS, and VMware, that runs in the background on the computer where you have installed your 3ware controller. When 3DM2 is running as a service or daemon, you can use your browser to access 3DM2 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 3DM2 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 3DM2 to configure RAID units and designate hot spares, and to perform maintenance tasks on RAID units.
