When satisfied [L5+ (M-1) * Δ X5+ (M-1) * L5]/L4≤1, Kx=1, Ky=0; Namely, the HBA card that will place does not exceed the border of the 4th layer of subordinate server, and the described HBA card that will add of placement need not to enter a new line;
Abscissa Xf and the ordinate Yf of layer 6 equipment are:
Xf＝X6+(C6m-1)*ΔX6+(C6m-1)*L6；
Yf＝max(Ye)+ΔY+H5；
Because arrangements that may enter a new line of layer 5 equipment, for the situation of line feed: the ordinate Ye of the layer 5 equipment of different rows is not identical yet, and described max (Ye) is the value of maximum in each equipment Ye value of layer 5;
Abscissa Xg and the ordinate Yg of layer 7 equipment are:
Xg＝X7+(C7m-1)*ΔX7+(C7m-1)*L7；
Yg＝Yf+ΔY+H6。
Step 104 by annexation and absolute coordinate position, presents network topology.
Abscissa Xcenter and the ordinate Ycenter of first equipment center point of each layer are:
Xcenter＝(Xn+Ln)/2；
Ycenter＝(Yn+Hn)/2。Be current, can take (Xcenter, Ycenter) as topological node line end points, draw topology.
