Problems solved by technology

However, in such a system, when the mapping data stored in the volatile memory of the host becomes unavailable or lost due to some reasons (for example, a sudden power failure of the host), the host may partially lose access to the data stored in the volatile memory. Access to data in storage devices

Embodiment Construction

[0024] Details of the present disclosure are described below with reference to the accompanying drawings.

[0025] [Storage System]

[0026] figure 1 The configuration of the storage system 1 according to the embodiment is shown. The storage system 1 includes a host 3 , one or more storage devices 2 , and an interface 10 configured to connect the host 3 and each of the storage devices 2 . In this embodiment, the storage system 1 is as figure 2 2U storage device shown. That is, the host 3 and one or more storage devices 2 are accommodated in a housing having the size of a 2U storage device. Each of the storage devices 2 is a non-volatile storage device, such as a 2.5 inch form factor (facotr), 3.5 inch form factor, M.2 form factor or add-in card (AIC) form factor. In addition, in this embodiment, the interface 10 adopts a PCI Express (Peripheral Component Interconnect Express, PCIe) interface. Alternatively, the interface 10 may adopt any other technically feasible proto...

Abstract

A storage device includes: a non-volatile memory including a plurality of physical blocks; a communication interface connectable to a host; and a controller. The controller is configured to generate metadata of host data, the host data including user data and metadata of the user data, and when the host data is received through the communication interface in association with the write command, the nonvolatile memory The metadata of the host data, the metadata of the user data, and the user data are written consecutively in the physical block of the host data, the metadata of the user data, and the user data.

Description

[0001] Cross References to Related Applications [0002] This application is based on and claims priority to US Nonprovisional Patent Application 15 / 296,841, filed October 18, 2016; the entire contents of which are hereby incorporated by reference. technical field [0003] The present disclosure generally relates to storage devices, storage systems, and computing devices. Background technique [0004] A storage system typically includes a host and one or more storage devices, each of which may include one or more non-volatile memory chips, such as NAND flash memory chips. In order to determine a physical location where data is stored using an identifier of data or a logical address of data, map data is stored in each of the storage devices or in a host, and the physical location of data is determined by referring to the map data. Specifically, in one type of storage system, such mapping data is stored in each of the storage devices, and the location of the data communicated...
