A storage structure and method having multiple protocol processor units are disclosed. The storage structure comprises a host CPU, a main memory, a storage device, a switch fabric, and a host bus adapter module. The host bus adapter module includes a plurality of protocol processor nodes for processing frames received from a network, and storing those frames into the storage device. A processing module of the host bus adapter module extracts the session information of each frame and compares it with entries recorded in a look-up table. If the connection information hits one entry of the look-up table, the frame can be bypassed into a corresponding protocol processor node according to the definition of the look-up table. Otherwise, a new entry will be inserted into the look-up table for designating a corresponding protocol processor node.

The invention provides a method for adjusting a speed-detection device for an object lens in an optical pickup head. The invention provides an adjusted optical disc drive, wherein the optical pickup head is accelerated/decelerated and the speed-detection device outputs a standard signal level. Next, the optical pickup head of an unadjusted optical disc drive is accelerated/decelerated under the same condition, and the speed-detection device outputs a speed signal level. Finally, the gain of a programmable gain amplifier is adjusted until the speed signal is equal to the standard signal.
