Abstract

The invention discloses a storage expansion cabinet which comprises a host controller and a Tri-mode chip Tri-mode switch connected with the host controller, and a storage device connected with the Tri-mode chip Tri-mode switch. Common expansion cabinet interface chip only simply supports one of a PCIE bus and an SAS bus, and Tri-mode chip Tri-mode switch can configure a physical port into an SASbus port or a PCIE bus port (wherein the SAS bus port is compatible with an SAT port). Therefore, the three-mode chip Tri-mode is connected with the host controller and the storage device, and varioustypes of storage devices can be supported, the number of the SAS bus ports and the number of the PCIE bus ports are configured according to the requirements of a client, different requirements of theclient for the expansion cabinet are met, and the repeated design of the expansion cabinet is reduced.

Description

technical field [0001] The invention relates to the technical field of storage, in particular to a storage expansion cabinet. Background technique [0002] In the era of cloud computing, the amount of data is increasing, the data center has an increasing demand for storage, and the requirements for equipment reliability and flexibility are getting higher and higher. In the past, the design of expansion cabinets was divided into two types: disk expansion cabinets JBOD (Just a Bunch Of Disks) and flash memory expansion cabinets JBOF (Just a Bunch Of Flash) according to customer needs. Among them, the disk expansion cabinet JBOD supports hard disk or solid-state disk SSD with SAS interface and SATA interface, and the flash memory expansion cabinet JBOF supports non-volatile storage disk NVME SSD with PCIE interface. Facing different customer needs, these two expansion cabinets are often A large number of repetitive designs are required, resulting in a waste of research and dev...
