Embodiment Construction

[0040] In order to make the purpose, technical solution and advantages of the present disclosure clearer, the implementation manners of the present disclosure will be further described in detail below in conjunction with the accompanying drawings.

[0041] figure 1 is a schematic diagram of an application scenario of an embodiment of the present disclosure. In this application scenario, a connection is established between the storage device 101 and the host 102. For example, the storage device 101 may be installed on the host 102, or the storage device 101 may be connected to the host 102 through a network, and the network may refer to the Internet.

[0042] When the storage device 101 is installed on the host 102, the storage device 101 and the host 102 interact based on the NVMe protocol. When the storage device 101 and the host 102 are connected through a network, the storage device 101 and the host 102 interact based on the NOF protocol. Among them, the NOF protocol is a...

Abstract

The invention provides a storage device and an element management method of the storage device, and belongs to the technical field of storage. The method comprises the following steps: detecting a subscription event indicated in a subscription instruction sent by a host; when the subscription event is detected, recording event information of the detected subscription event, and notifying the hostto enable the host to send an event information acquisition instruction; and sending the event information to the host according to the event information acquisition instruction. Based on the method provided by the invention, the host in the network can timely obtain the event and the event information of the element in the storage device.

Description

technical field [0001] The present disclosure relates to the field of storage technologies, and in particular to a storage device and a method and device for managing components of the storage device. Background technique [0002] A flash disk frame (Just a Bunch of Flash, JBOF) is a high-performance and low-latency storage device, which includes at least one solid state drive (Solid State Drives, SSD). With the expansion of the Non-Volatile Memory express (NVMe) protocol to the NVMe network access (NVMe over Fabric, NOF) protocol, the SSD installed on the remote JBOF can directly provide storage data services to the host through the network . [0003] Since the NOF protocol is extended by the NVMe protocol, the NOF protocol includes all instructions defined in NVMe, and also includes the subscription instructions provided by the NVMe protocol. The subscription instruction is an asynchronous notification mechanism, and the host can send it to each SSD in JBOF. The subscrip...
