Embodiment 1

[0023] A design method of MemoryRiser card based on Openpower processor, the computing board is interconnected with two high-speed connectors and the memory board, and the communication and control signals of the two are all on these two connectors; the high-speed connector of the computing board The interface is set on the upper right end of the computing board, the memory board is designed in the shape of a rectangular handle with a gap in the lower left, and the high-speed connector interface is set in the lower left gap.

Embodiment 2

[0025] On the basis of Embodiment 1, the high-speed connector described in this embodiment is selected by parameters, and the 25G high-speed connector of the Impact series of Molex is used. Each column has 4 differential pairs, 10 columns, and a total of 120 pins.

Embodiment 3

[0027] On the basis of Example 2, the computing board of this example uses 1703353106 and 1703355106 with male headers, and the memory board uses 1703403020 and 1703405020 with female headers.

[0028] One of these two connectors is Left Guide, Open Endwall, and the other is Right Guide, Open Endwall, so that they can be matched with one left and one right. In addition to saving space, they can also play a good role in fixing.

Abstract

The invention discloses a MemoryRiser card designing method based on an Openpower processor. A computer board is connected with a memory board through two high-speed connectors, and communication and control signals of the computer board and the memory board are all located on the two connectors; a high-speed connector port of the computer board is formed in the right end of the upper portion of the computer board, the memory board is designed to be in the shape of a rectangular tool holder with a notch formed in the lower left portion, and the high-speed connector port is located at the position of the notch in the lower left portion. By using the high-speed connectors for connection, a memory bank on the lowermost side can sink to the space below the computer board during installation, the space of a 2U case is effectively utilized, and larger memory can be supported compared with the method that the memory board is directly inserted in the Top plane of the computer board.

Description

technical field [0001] The invention relates to the technical field of minicomputer servers, in particular to a design method of a MemoryRiser card based on an Openpower processor. Background technique [0002] IBM's high-end server market has begun to be impacted by X86-based servers, and its business costs are high. It will become more and more difficult to maintain the Power series alone. It will be more and more difficult to find partners with low business costs to expand to the low-end market. [0003] The processor that IBM opened to the Chinese market is an SCM package chip (Single Chip Module) code-named "Turismo". Each processor has 12 cores, each core is SMT8, and contains 2 memory controllers. Each controller supports mounting 4 Memory Buffer chips "Centaur", the high-speed bus between the processor and the Centaur chip is DMI, the signal rate is 9.6Gbps, and the bandwidth is 28.8GB / s. [0004] Openpower processor code-named "Turismo", each processor has 12 cores...
