Description of the Invention: [Technical Field] The present invention relates to a computer system, and in particular to a modular server and a processor thereof Module and MAC address management methods. [Prior Art] In order to provide management convenience and to maintain the system to run uninterruptedly, the modular design of the server is an inevitable trend. The Blade Server is one of the modular servers. Figure 1 is a block diagram showing a conventional blade servo. Referring to Figure 1, the blade server 100 can be inserted into a plurality of CPU blade units 110. The system management module 120 is used to manage the blade server 1〇〇. The system management module 12 may include a backplane 121, a system management blade (MBB) 122, and a network switch blade 123. The central processor blade module 110, the system management board 122, and the network switch board 123 are all coupled to the backplane 121. These CPU blade modules 110 share the network switch board 123 of the blade server system 100. Therefore, each central processor blade module 11 has a network interface controller (NIC) 111', and each network interface controller m has a unique media access control (Media Access Control, MAC). ) Address. The above MAC address is recorded in the MAC address memory in. After the blade server 100 is powered on, the system management board 122 of the system management module 12 records the MAC address in each CPU blade module 11 (). When one of the central processor blade modules 110 fails, the user is allowed to replace the faulty blade module due to the modular design of 200929980-J60twf.doc/n. When one of the CPU blade modules 110 is replaced, the MAC address of the new CPU blade module 110 must be different from the MAC address of the original CPU blade module. At this time, the blade server is 1〇. 〇 Some services may be interrupted by resetting the new MAC address. In order to avoid interruption of service, the traditional technology is to provide the base management module (BMC) of the original CPU blade module 110 by the system management module 120 to the MAC address of the original CPU blade module. 113 as the virtual MAC address, and then in the Power On Self Test (POST) phase of the new CPU blade module 110 from the basic input and output system (Basic Input / Output System, BIOS) from the substrate management control The virtual MAC address is obtained, and the virtual MAC address is written to the MAC address memory 112 of the network interface controller 111 to overwrite (replace) the MAC bit of the new central processor blade module 110 itself. Address (hereinafter referred to as the actual MAC address). Therefore, 'this new CPU blade module can continue to use the MAC address (virtual MAC address) of the original CPU blade module. At this time, the blade server does not need to reset the new MAC bit. The address does not interrupt the service. In other words, the blade server 100 records the MAC addresses inside all of the CPU blade modules 110 on the system management board 122. After the central processor blade module 110 is removed, the BIOS of the new CPU blade module 110 is read and recorded in the MAC address memory 112 through the north bridge wafer 114 and the network interface controller 1.

In another embodiment, the baseboard management controller 215 can be directly coupled to the second memory 219 to write the virtual MAC address. In other embodiments, the central processing unit 211 executes the BIOS instruction code stored in the BIOS memory 214 and the firmware of the network interface controller 216, and the substrate management controller 215 can transmit the virtual MAC address. The south bridge chip 213 is transferred to the BIOS; the BIOS can then write the virtual MAC address to the second memory 219 through the north bridge chip 212, the network interface controller 216, and the selector 217. The two MAC address memories 218 and 219 are both connected to the network interface controller 216 via the selector 217. In the normal mode, selector 217 selects to have first memory 218 connected to the network interface controller, at which point network interface controller 216 communicates externally using the actual MAC address. 13 200929980 __360twf.doc/n After replacing one of the processor modules, the new processor module 210 can obtain the MAC address of the original processor module (not shown) from the system management board 222 (virtual MAC address). The baseboard management controller 215 can write the virtual MAC address to the second memory 219 in accordance with the above manner. At this time, the actual MAC address and the virtual MAC address are recorded in the two MAC address memories 218 and 219 of the processor module 210, respectively. At the same time, the 'substrate management controller 215 controls the selector 217 to cause the selection device 2 to select to connect the second memory 219 to the network interface controller 216. At this time, the network interface controller 216 uses the virtual MAC address (originally processed). The MAC address of the module is external communication. Therefore, the blade server 200 does not need to reset the new mac address. Assume that the user does not restore the virtual MAC address of the processor module 210 to the actual MAC address, and directly operates the processor module 21 to other blade servers (not shown), because the processor module 21 The actual MAC address is not removed/overwritten' so the network interface controller 216 can communicate externally using the actual MAC address. Therefore, the processor module 210 of the embodiment can ensure the uniqueness of the MAC address and avoid the error of network communication. At the same time, in the processor module swapping operation, the new processor module 210 can temporarily change its mac address so that the blade server 200 does not need to reset the new MAC address. The embodiments of the present invention are not limited to the above embodiments, and the present invention can be implemented in other ways. For example, FIG. 3 is a block diagram showing the circuit of a modular server and its processor module in accordance with another embodiment of the present invention. The contents of this embodiment can be implemented with reference to the description of the embodiment shown in FIG. 2, so 200929980 -------- 360twf.doc/n will not be described again. In the present embodiment, the selector 217 can be implemented with the switch SW. The switch SW is selected to connect the network interface controller 216 to the first memory 218 or to connect the network interface controller 216 to the second memory 219 in accordance with the control of the substrate management controller 215. The baseboard management controller 215 is further coupled to the second memory 219 to directly write the virtual MAC address to the second memory 219. For another example, FIG. 4 is a block diagram showing a circuit of a modular servo device and a processor module thereof according to still another embodiment of the present invention. The contents of this embodiment can also be implemented by referring to the description of the embodiment shown in FIG. 2, and therefore will not be described again. In the present embodiment, the selector 217 can be implemented by the address converter 417, and the first memory 218 and the second memory 219 can be realized using a single memory chip NVRAM. The memory chip NVRAM can be a non-volatile memory such as a flash memory, an electronic erasable read-only memory, or the like. The memory space of the memory chip NVRAM is defined as at least two parts, one of which is the first memory 218 and the other part of which is the second memory 219. The network interface controller 216 can access the first memory 218 or the second memory 219 through the addressing of the address converter 417. . According to the control of the substrate management controller 215, the address converter 々I? can select the network interface controller 216 to access the first s memory 218 of the memory chip NVRAM, or select the network interface controller 216 accesses the second memory 219 of the memory chip NVRAM. The base management controller 215 writes the virtual mac address to the second memory 219 through the address converter 417. The method for managing the media access control address in the above modular server 200 and its processor module 210 can be implemented in the following steps: 1° 15 200929980 (360 twf.doc/n)
