Patent ID: 10025742

Abstract:
A JBOD apparatus (1) having a hard disk drive (HDD) expander (11), a switch (13) and a BMC module (12) is disclosed. The HDD expander (11) is connected to a plurality of hard drives (5) respectively. The switch (13) connects the HDD expander (11) with a connecting port (14) for enabling a first transmission channel, or connects the HDD expander (11) with the BMC module (12) for enabling a second transmission channel. The BMC module (12) is connected to an Ethernet through a network port (17). The HDD expander (11) initially receives a wired transmitted command through the first transmission channel. When the BMC module (12) receives an Ethernet transmitted command through the Ethernet, it controls the switch (13) to change for enabling the second transmission channel, therefore, the BMC module (12) executes an interactive operation with the HDD expander (11) in accordance with the Ethernet transmitted command.
