Description

Technical Field

[0001] The present invention relates to the technical field of solid state hard disks, and in particular to a non-contact log collection device and method. Background Art

[0002] U.2 interface enterprise-level solid state drives (SSDs) can be divided into three types according to protocol type: Serial ATA (SATA), Serial Attached SCSI (SAS), and Non-Volatile Memory Express (NVMe). NVMe SSDs have become the mainstream memory for high-end storage due to their excellent read and write performance, so NVMe SSDs have become the focus of development for major SSD manufacturers. In the development process of NVMe SSDs, it is inevitable that some software, hardware, or structural problems will arise. Solving these problems is the key task in the development process of NVMe SSDs. An important means to solve these problems is to export logs to analyze the causes of the problems.

[0003] NVMe SSD log export methods are divided into in-band and out-band. As the name implies, the in-band uses the NVMe underlying PCIe protocol, and the out-band uses other debugging interfaces reserved by the NVMe SSD Controller, such as JTAG, SMBus, and UART. In the process of NVMe enterprise-level SSD productization, the in-band and UART log export methods will be retained. For problems with hard disk recognition (SSD is at the bug site and cannot be recognized normally after powering on again), UART log export is required. For some hard disks that are difficult to reproduce or cannot be plugged in and out in time (high and low temperature tests in the incubator, RDT tests), it is more difficult to export logs.

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0031] In this embodiment, a non-contact log collection device is provided, such as Figure 1 As shown, it includes: a remote control transmitting circuit, a remote control receiving circuit, a wireless transparent transmission circuit, a control interaction circuit and an interface circuit, wherein the remote control receiving circuit, the wireless transparent transmission circuit, the control interaction circuit and the interface circuit are arranged on a board.

[0032] like Figure 1 As shown, the remote control transmitting circuit is connected to the remote control receiving circuit via wireless transmission, and the remote control transmitting circuit is used to encode the control command input by the user and send it to the remote control receiving circuit; the remote control receiving circuit is electrically connected to the control interaction circuit, and the remote control receiving circuit is used to decode the control command and send it to the control interaction circuit.

[0033] Specifically, the remote control transmitting circuit has a built-in encoder, the remote control receiving circuit has a built-in decoder, the remote control transmitting circuit and the remote control receiving circuit are connected in communication via wireless transmission. The related wireless transmission technologies include WIFI, Bluetooth, Zigbee, and 433M. Since the number of Bluetooth terminal nodes does not exceed 8, the Zigbee transmission rate is relatively low, and 433M is suitable for point-to-point. Therefore, this embodiment uses WIFI technology with the fastest transmission rate and a theoretical maximum of 255 nodes for uplink and downlink wireless data transmission.

[0034] like Figure 1As shown, the control interaction circuit is electrically connected to the wireless transparent transmission circuit, and the control interaction circuit is electrically connected to the NVMe SSD. The wireless transparent transmission circuit is electrically connected to the NVMe SSD debugging interface through the interface circuit, and the wireless transparent transmission circuit is connected to the terminal communication through wireless transmission.

[0035] Specifically, the control interaction circuit controls the wireless transparent transmission circuit to send the log data of the NVMe SSD to the terminal based on the control command, or realizes power-off and restart after the NVMe SSD firmware is updated, or controls the wireless transparent transmission circuit to enter a deep sleep state.

[0036] Specifically, the control commands may include: wake-up command, firmware update command, sleep command, etc. The control interaction circuit wakes up or sleeps the wireless transparent transmission circuit, or updates the firmware of the SSD by controlling the serial port between the control interaction circuit and the wireless transparent transmission circuit, and the serial port between the wireless transparent transmission circuit and the NVMe SSD according to the different commands received. The control interaction circuit software configures the MODE mode to reduce hardware operations and reduce the risk of electrostatic damage.

[0037] Optionally, in order to achieve a match between the remote control receiving circuit and the remote control transmitting circuit, security keys are set for both the remote control receiving circuit and the remote control transmitting circuit. When the remote control receiving circuit transmits a control command to the remote control transmitting circuit, the control command carries not only command information but also security key information. After receiving the control command, the remote control receiving circuit determines whether the security key is correct. If it is incorrect, the security key can be confirmed again to the remote control transmitting circuit. After multiple confirmations, if the security key is still incorrect, an alarm is issued and the control command is intercepted.

[0038] Optionally, the server has dozens of disks in full configuration, and the RDT test has more than 200 disks at most. If all these disks need to export logs, the traditional plug-in debug cable method can only be used to export logs one by one.

Figure 7 For the Type C SSD interaction interface, P3V3 power supply, JTAG debugging port, UART and MODE working mode interface are reserved. Because the SSD Controller IO is 1.8V level, a level conversion circuit is designed to match the UART and MODE levels to 1.8V and 3.3V.
