Storage device, memory and server

Abstract

The invention provides a storage device, a memory and a server, and the storage device comprises: a box body, the bottom of the box body is provided with a first opening, and the front surface of thebox body is provided with a second opening; the first storage part that is fixedly arranged at the bottom of the box body, is provided with a first group of hard disk interfaces and a first group of unloading cards, and is used for enabling hard disks to be inserted into the first group of hard disk interfaces through the first opening to be connected with the first group of unloading cards; the second storage part that is arranged above the first storage part, the upper portion of the second storage part is hinged to the box body so that the second storage part can rotate towards the second opening by a preset angle towards the exterior of the box body, and the second storage part is provided with a second set of hard disk interfaces and a second set of unloading cards, so that the hard disk is inserted into the second group of hard disk interfaces from the bottom of the second storage part to be connected with the second group of unloading cards when the second storage part is in therotating position. According to the scheme, a large storage space can be provided in a limited small space, and the load of a CPU is reduced in the storage process.

Description

technical field [0001] The field relates to the field of computers, and more particularly to a storage device, a memory and a server. Background technique [0002] With the development of the Internet, the data storage is getting bigger and bigger. In the case of a sharp increase in data, the requirements for storage performance are getting higher and higher. In order to increase the capacity of the hard disk, the power consumption of the hard disk is also increasing. Therefore, It brings about the balance of space, heat dissipation, capacity and speed. How to achieve high-density storage in a limited space and obtain a good heat dissipation effect is a problem that needs to be solved at present. Among the current server products, JBOD (disk assembly) and JBOF (hard disk assembly) are used to achieve high-density storage. The storage media are mainly 2.5-inch and 3.5-inch SAS, SATA disks and 2.5-inch NVME disks. By using SAS Expander to expand SAS and SATA resources, JBOF ...

AI Technical Summary

Problems solved by technology

[0003] Currently, JBOD servers mainly use 3.5-inch hard disks for mainstream storage. 3.5-inch disks are large in size, heavy in weight, and low in storage density. They also face many challenges in the design of the whole machine in terms of structure and heat dissipation. SAS Expander (expansion card) cards are used to expand resources. Storage performance will also be limited

JBOF servers mainly use 2.5-inch NVME disks for storage. NVME hard disks can expand storage resources through PCIESWTICH connections, but all data processing still depends on the CPU. If the CPU is directly connected to NVME, the number of hard disks is very limited.
