Scheme design of PCIE (Peripheral Component Interconnect Express) high-speed storage device

Abstract

The invention provides a scheme design of a PCIE (Peripheral Component Interconnect Express) high-speed storage device. A micro CPU (Central Processing Unit), an RAID (Redundant Array of Independent Disk) chip and an SAS (Serial Attached SCSI) extended chip are integrated on a PCIE board card; an RAID check function is integrated; the SAS extended chip is connected; RAID management can be performed on an extended disk through the SAS extended chip; meanwhile, a large-capacity MSATA SSD (mini SATA Solid State Disk) is connected through a PCIE switch change; the CPU is provided with a cache per se; in the entire small system, data is stores in three stages, namely CPU buffer, SSD, SAS connected at the rear end and the SATA disk. Compared with the prior art, the scheme design has the advantage that high extension is realized on the premise of preventing performance loss; compared with the conventional SAN (Storage Area Network) framework storage, the scheme design has the advantage of low cost. The scheme design also has the characteristics of rational design, simple structure, convenience in use and the like, and thus has a great use value.

Description

technical field [0001] The invention relates to the field of high-expansion PCIE SSD storage devices, in particular to a scheme design of PCIE high-speed storage devices. Background technique [0002] The rapid development of enterprises has brought about the rapid growth of data. At the same time, the bandwidth and IOPS requirements of the back-end storage are also getting higher and higher, and the expansion requirements of the disk space are increasing. The old storage cannot meet the performance and capacity of business applications. Not enough, and the cost of replacing a new SAN storage device is too high, so this paper proposes a storage solution that combines PCIE SSD, RAID chip, and SAS expansion chip to improve storage device performance and high expansion. This solution is low in cost and can simultaneously expand performance and capacity. It is a storage solution with high performance, high scalability, and high cost performance. [0003] At present, many compan...
