A first storage part and a second storage part having a U board slot and / or a plurality of power supply board slots are provided on the first surface and a second surface opposite to the first surface. Therefore, it is possible to secure the power supply necessary for the processing and pack more CPUs in the limited space. In addition, the first storage unit includes a CPU board slot, and
Since the storage part of has a power supply board slot, the influence of heat generated from the power supply board on the CPU board is reduced,
It has become possible to prevent the failure of the CPU due to heat.
Furthermore, since the connection terminals are formed so as to face the surface that can be released to the outside, it is possible to perform setting and maintenance work such as cable connection from the releasable surface as easily as before. .

Furthermore, the rack mount size is 19 inches, and the height is about 177.8 mm or about 311.1.
5 to 355.6 mm, and the vertical length is approximately 100
Since a CPU board and a power supply board of mm or approximately 233.35 mm are stored, versatility and redundancy are high, and it is possible to reduce system upgrade costs, maintenance costs, and the like. Furthermore, since the CPU board slot and / or the power supply board slot are vertically divided in the vertical direction and the detachable dividing portion is provided, it is possible to further improve the request and the redundancy.
