Built-in high-end storage card supporting Tri-Mode

Abstract

The invention discloses a built-in high-end storage card supporting Tri-Mode. The built-in high-end storage card comprises a PCB, a Raid controller, a DDR4 cache array, a PCIE host interface, a built-in connector interface, a Fimware storage unit, a data protection and super-capacitor interface unit, a clock unit and a power supply unit, wherein the Raid controller, the DDR4 cache array, the PCIE host interface, the built-in connector interface, the Fimware storage unit, the data protection and super-capacitor interface unit, the clock unit and the power supply unit are arranged on the PCB. The Raid controller is connected with the DDR4 cache array, the PCIE host interface, the built-in connector interface, the Fimware storage unit, the data protection and super-capacitor interface unit, the clock unit and the power supply unit separately, the built-in connector interface is connected with a built-in connector, and the built-in connector is connected with disks. According to the built-in high-end storage card, hybrid deployment of SAS / SATA / NVME disks is achieved through one PCIE board card, so that the mainboard PCIE expense is reduced, the case wiring complexity is lowered, and the system cost is reduced.

Description

Technical field [0001] The present invention relates to a built-in high-end memory card supporting Tri-Mode, specifically an 8-port built-in memory card supporting Tri-Mode (three-mode, SAS / SATA / PCIE or SAS / SATA / NVME). It supports high-end Raid-level Raid0 / 1 / 5 / 6 / 10 / 50 / 60, and has a variety of DDR cache specifications from 1GB-8GB, which belongs to the field of server storage technology. Background technique [0002] With the development of cloud computing technology and big data applications, the market has more and more integrated functional requirements for servers. It requires both traditional SAS and SATA mechanical disks to increase the capacity, and also requires the use of SSDs, especially NVME SSDs, to achieve high-performance and low-latency applications. Therefore, the market demand for hybrid deployment of SAS / SATA / NVME disk server systems is becoming more and more extensive. [0003] To achieve the traditional solution of hybrid deployment of SAS / SATA / NVME disks in se...

AI Technical Summary

Problems solved by technology

This solution occupies many PCIE slots (at least 2) on the motherboard, takes up a large amount of space on the server, and has high implementation costs. It also does not support the Raid (Redundant Array of Independent Disks) function of the NVME disk, and cannot Realize data redundancy protection of NVME disk, there are many disadvantages
