Adapter board, and method and device for expanding storage device

Abstract

The embodiment of that present application discloses an adapter board, and a method and a device for expanding a storage device, wherein the adapter board comprises at least two eight-channel slots. Any two eight-channel slots are arranged in parallel, so that two eight-channel slots arranged in parallel can be combined into one sixteen-channel slot, under normal circumstances, a user can insert two eight-channel label cards for data transmission, and when a user needs a high transmission rate, a 16-channel standard card can be inserted for data transmission, so compatibility between the eight-channel standard card and the sixteen-channel standard card is realized. Alternatively, through modification of the configuration file, the ports of the two eight-channel slots installed in the x16 standard card are configured as the ports of the x16 slot, so that the x16 standard card transfers data according to the configured ports, thereby realizing the mixed insertion of the x8 standard cardand the x16 standard card, meeting the different needs of users and improving the user experience.

Description

technical field [0001] The present application relates to the technical field of computer storage, and in particular to an adapter board, a storage device expansion method and a device. Background technique [0002] With the continuous development of random computer technology, people have higher and higher requirements for data transmission performance and protection performance. In order to meet the high-quality service requirements, the high-speed serial computer expansion bus standard (peripheral component interconnect express, PCIE) came into being. [0003] The PCIE standard specifies multiple width slots, for example, x1, x4, x8, x16, such as figure 1 As shown, where x1 indicates a single-channel link, and x4 indicates a four-channel link, and the greater the number of channels, the greater the transmission rate. In order to support the PCIE standard protocol, major equipment manufacturers have produced PCIE standard cards, which can provide high-speed serial point-t...

AI Technical Summary

Problems solved by technology

[0004] In the existing technology, due to the fixed configuration between each slot and the standard card of the corresponding width, only x8 PCIE standard cards can be installed in the x8 slots. When users need high transmission efficiency, it is impossible to combine two x8 slots Configured as a x16 slot to install x16PCIE standard card, resulting in failure to meet user needs and affect user experience
