7	Terminal Operation

7.1Power on RAID Enclosure

Hardware installation should be completed before powering on your RAID enclosure. Drives must be configured and the controller properly initialized before host computer can access the storage capacity. The configuration and administration utility resides in controller's firmware.

Open the initial terminal screen: use arrow keys to move cursor bar through menu items, then press [ENTER] to choose the terminal emulation mode, and [ESC] to return to the previous menu/screen.

7.2Caching Parameters

Optimization Modes

Mass storage applications can be roughly categorized into two as database and video/imaging, according to its read/write characteristics. To optimize the controller for these two categories, the controller has two embedded optimization modes with controller behaviors adjusted to different read/write parameters. They are the “Optimization for Random I/O” and the “Optimization for Sequential I/O.”
