Adapter card of special-shaped memory card

Technical Field

The utility model belongs to the technical field of computer equipment, concretely relates to adapter card of dysmorphism storage card.

Background

Currently, RAID storage cards (also called disk array cards) can combine a plurality of independent physical hard disks in different ways to form a logical hard disk, thereby providing higher performance than a single hard disk and providing data redundancy, and are widely used in servers. A plurality of network cards supporting PCIe buses, RAID/SAS cards and other external plug-in devices can be accessed from standard PCIe slots on the server. However, as the performance requirements of servers continue to increase, the number of PCIe slots is increasingly required. Mezzanine (Mezz) card is an ideal choice. Unlike the design requirements of half height and half length of a standard external plug-in card, the Mezz card can be customized according to the design requirements of the structure. The shape may be a rectangle in appearance or a special shape such as a polygon. The height limit requirement of the whole PCIe extrapolation device is not considered more in the structural height. From the perspective of the front of the server, the special-shaped card is a middle interlayer buckled on the mainboard through a connector. The PCIe bus has the advantages that the PCIe bus does not occupy a standard PCIe slot position, but is connected with the PCIe bus of the mainboard through other connectors; smaller than standard PCIe connectors and space-saving.

However, the design of the special-shaped card also brings a disadvantage that the universality is poor. If there is no motherboard supporting the profile card connector (e.g., OCPA2.0 connector), the profile card cannot fit on the motherboard. Particularly, in the development and test stage of the special-shaped card, an OCPA mainboard test platform needs to be built; meanwhile, due to the fact that the space between the special-shaped card and the main board is narrow, the testing tool cannot penetrate into the observation signal, the testing tool can only be achieved by flying wires, and the testing efficiency is poor due to the fact that the space is limited.
