Description
Technical Field
The present invention relates to an electrical communication device, and more particularly, to a circuit board assembly and a communication device including the same.
Background
Currently, a conventional computer architecture includes hardware devices such as a blade-type single board and a chassis. As shown in fig. 1, the blade-type single board includes a front board 1 and a rear board 2, the front board 1 and the rear board 2 are inserted into each other, and the plurality of blade-type single boards are electrically connected through a backplane 3.
The blade type single boards are divided into SERVER single boards and SWITCH single boards, all the SERVER single boards are connected with the SWITCH single boards through internal backboard wiring to form a computer network group, and various complex operation functions are completed in a multi-processor cooperation mode.
As shown in fig. 2, in the existing computer architecture, a BASE (basic) plane and a FABRIC (FABRIC) plane in a board are directly disposed on a front board 1 of the board and managed by a BMC (board management) module.
In addition, 12 gigabit ethernet electrical interfaces (not shown) are provided on the board for connecting with external ethernet switching devices.
The computer architecture integrates two planes on a single board, and can realize interconnection through a backboard to complete huge service calculation and exchange functions, but has the following disadvantages:
firstly, for a system with a small traffic volume, only one BASE plane is needed to meet the requirements of the system, and the FABRIC plane originally configured by the single board increases the cost of the system, thereby bringing economic burden to users.
Secondly, because the BASE plane and the FABRIC plane are directly arranged on the front plug board 1 of the single board, the flexibility of various configurations of the system is poor, and the system cannot adapt to various user requirements along with the continuous expansion of new user requirements.
In addition, for the increasing processing speed, the structure of the single plate fixing is gradually unable to adapt, for example: when a single board is connected with external ethernet switching equipment, only 12 gigabit ethernet electrical interfaces are available, which cannot meet the gradually rising transmission requirement of FC (fiber channel control chip) up to 4Gbps, and cannot establish an SAN (area storage) network through built-in switching equipment.
In the above applications of such computer architecture, such as an ATAC (advanced telecommunications computing architecture) system, if an external storage device is required to form a storage network, two connection methods are generally adopted:
one is, as shown in fig. 3, a SERVER board in the ATCA system is used to directly connect to a disk array, and some SERVER boards in the system are directly connected to a storage device through an optical fiber interface, so that the storage device can be directly accessed. However, when the SERVER board not connected to the storage device in the ATCA system needs to access the storage device, the SERVER board accesses the storage device through the ATCA internal switching network and then through the SERVER board directly connected to the storage device, and the communication performance of the SERVER board is affected, thereby forming a bottleneck in performance. The expansion capacity of the storage equipment is limited due to the limitation of the number of the SERVER single boards and the optical fiber interfaces of the storage equipment in the ATCA system;
another is that an external FC SWITCH (fibre channel SWITCH module) is required to build a SAN (area storage) network, as shown in fig. 4.
The ATCA system is connected with the FC SWITCH through the optical fiber channel, and the disk array is also connected to the FC SWITCH, so that a server single board in the ATCA system and an external storage array are connected through the FC SWITCH to jointly form an SAN network. The SERVER single board in the ATCA system can access the external storage device through the SAN network. However, because an external FC SWITCH needs to be purchased separately, the cost is high, external wiring is complicated, and the stability and reliability of the system are reduced. And the FC SWITCH and ATCA systems belong to different control systems respectively, and unified management cannot be achieved.
In addition, when the SERVER processing module in the ATCA system is connected to the external FC SWITCH through the optical fiber channel, a GBIC (gigabit interface converter) must be added to convert the external optical signal into an electrical signal, and after the electrical signal of the ATCA system is converted into an optical signal, the SERVER processing module can exchange information with the external FC SWITCH. Increasing system cost and reducing transmission rate.
