At several aspects such as management, data, power supplies the method that the embodiment of the invention provides is described in detail respectively below.
At management aspect, the embodiment of the invention provides a kind of management topology star-like and that bus-type mixes to be connected, an IPMB-L is connected with the MMC of at least 2 AMC among the IPMB-L that MCH is provided, the topological connection diagram of a kind of management that Fig. 5 provides for the embodiment of the invention, in this embodiment, support that with MicroTCA 24 AMC are that example is described.As shown in Figure 5, this MicroTCA system comprises redundant MCH, promptly comprises MCH1 and MCH2.The management channels that keeps MCH to provide is constant, and promptly MCH still provides 12 IPMB-L, but every IPMB-L that MCH provides is connected with the MMC of two AMC respectively, and at this moment, the MicroTCA system just can support 24 AMC, and MCH can realize the management to 24 AMC.In addition, do not limit the quantity of the AMC that shares an IPMB-L management port, also can be for a plurality of AMC share an IPMB-L management port, as shown in Figure 6.
27 IPMB-L addresses have been defined in the AMC standard, because address 8A does not wherein use as reserving the address to A0, so, in the present invention, these addresses of reserving address and standard definition are all offered AMC uses, for example, can use to other AMC except 12 AMC the address assignment of reserving, as shown in table 3, the address assignment of IPMB-L in the MicroTCA system that the table 3 expression embodiment of the invention provides, the address 8A that reserves is distributed to the 13rd to 24 AMC to A0, and this moment, the MicroTCA system just can support 24 AMC.Simultaneously, because in the MicroTCA system that supports 12 above AMC, the quantity of CU and PM does not need to increase, so MCH does not need to change to the management of CU and PM by IPMB-0, still adopts the form of bus, the address of IPMB-0 does not need to increase yet.
Table 3
Aspect exchanges data,, the MicroTCA system needs to redistribute the exchanges data port of MCH if supporting the AMC more than 12.The embodiment of the invention offers 12 above AMC with the master data switching port of MCH with the growth data switching port and is connected.Can adopt master data switching port to be connected, in the growth data switching port of other each AMC beyond these 12 AMC and MCH any one is connected with the exchanges data port of 12 AMC with MCH.Along with the bandwidth of switching port increases gradually, master data switching port Fabric[A] just can satisfy the exchanges data demand of original 12 AMC, so just can be simultaneously with growth data switching port Fabric[D～G] switching port of distributing to other AMC beyond these 12 AMC uses.And, with growth data switching port Fabric[D～G] and when the switching port of distributing to other AMC beyond these 12 AMC used, its method of salary distribution was more flexible, which AMC that does not limit wherein shares original Fabric[A] or Fabric[D～G].Each AMC all adopts being connected of point-to-point with the master data switching port of MCH with the growth data switching port.
Table 4 is a kind of distribution condition of MCH exchanges data port, in the table 4, n=1,2 ... 12.If the switching bandwidth of MicroTCA system can satisfy switching requirement, when the MicroTCA system need support 12 above AMC, can be as shown in table 4, Fabric[A], Fabric[D～F] same as the prior art, still offering original 12 AMC connects, and with Fabric[G] offer other AMC connection except original 12 AMC, to carry out exchanges data.Certainly, also can adopt the method for salary distribution of other switching port.
