The remote management method can be used in the remote management system 10 shown in FIG. 1 above, and includes the following steps: First, as shown in step 510, the management server 130 manages the first remote management device 110 and the second remote management. Information of device 120 is passed to client computer 20 to generate first menu 60. The information of the first remote management device 110 and the second remote management device 120 includes, for example, the model number of the first remote management device 110 and the second remote management device 120, the number of connections, and whether the connection port is connected (on- Line), port type, protocol address (IP Address), and media access control (MAC) address. The first menu 60 lists the ports 112(1) to 112(M) shown in FIG. 2 and the ports 122(1) to 122(N) shown in FIG. 3 for management by the user. Therefore, the user only needs to know the IP address of the management server (the user does not need to know the IP address of the first remote management device 110 and the second remote management device 120), and thus the IP address is logged in (Login). The first remote management device 110 and the second remote management device 120 can be managed after the server is managed.

The ports 埠 112(1) to 112(M) shown in FIG. 2 and the ports 122(1) to 122(N) shown in FIG. 3 are connected to the servers PC-1-1 to PC-1, respectively. -M and server PC-2-1 to PC-2-N, so the ports 埠112(1) to 112(M) and ports (122(1) to 122(N) listed in the first menu 60 can be servoized. The devices PC-1-1 to PC-1-M and the servers PC-2-1 to PC-2-N are represented (as shown in Fig. 6). Next, as shown in step 520, the hypervisor 140 provides a first menu 60. In a preferred embodiment, the first menu 60 displays the first remote management device 110 and the second remote management device 120 in a third-order tree structure, and the server PC-1-1 under its jurisdiction. Up to PC-1-M and server PC-2-1 to PC-2-N, wherein the management server 130 is the zeroth order; the first or second remote management device of the first figure is the first order; The connection of the one or the second remote management device is the second order. In a preferred embodiment, after the first menu 60 is established, if a third remote management device (not shown) is connected to the network 30, the third remote management device actively communicates with the management server 130.

In addition, if the first menu is a Q-order tree structure, the order of the second menu is not greater than Q, for example, a Q-1 order tree structure. For example, in more detail, the first menu is a third-order tree structure (where the first map management server is the zeroth order; the first or second remote management device of the first map is the first order; the first or the first The connection between the two remote management devices is the second order), and the second menu is a second-order tree structure (where the first picture management server is the zeroth order; the connection between the first or second remote management device is the first level one). In other words, this second menu does not show which remote management devices are provided by these connections. On the other hand, since the first remote management device or the second remote management device can be different types of remote management devices, for example, the first remote management device is a network type KVM switch, and the second far The end management device is a network type power management device, so that the user of the patent can freely combine some ports of the first remote management device with certain ports of the second remote management device, and use It feels like managing a "virtual device" with both a computer connection and a power supply. Since the ports 埠 112(1) to 112(M) and the ports 122(1) to 122(N) of the aforementioned first menu 60 are served by the servers PC-1-1 to PC-1-M and the server PC- 2-1 to PC-2-N indicate that, therefore, the user is from the server PC-1-1 of the first list 60 to the PC-1-M and the server PC-2-1 to the PC-2-N. Select the server you want to manage. For example, if the user wants to manage the server PC-1-1, the server PC-1-2, the server PC-2-1, and the server PC-2-2, the user is from the first list 60. The second list 70 is created by selecting the server PC-1-1, the server PC-1-2, the server PC-2-1, and the server PC-2-2, at which point P is equal to four. The server PC-1-1, the server PC-1-2, the server PC-2-1, and the server PC-2-2 of the second list 70 respectively represent the port 112(1) and the port 122 ( 2), port 122 (1) and port 122 (2).

Since the number of connections listed in the second menu 70 is less than the number of connections listed in the first menu 60 (possibly up to 65535), the user can more effectively manage the particular interest through the second menu 70. Or a connection that feels particularly important. In other words, the user establishes the required connection menu through a single management interface to improve operational efficiency and convenience.

Moreover, in addition to the aforementioned steps 510 to 530, the remote management method can further switch and set the user's authority to provide an elasticized user access authorization mode. Among them, the administrator can set the access rights of each port for a specific user. Each port can be accessed by a single user, and the administrator can individually set the security mode for system login for each port.
