在 Windows 或 Linux 上使用 NVMe SSD 的基本工具
项目描述
带有控制台命令的 Python 包，用于列出、读取和测试安装在运行 Windows 和 Linux 操作系统的计算机中的 NVMe SSD。
特征
- 控制台命令：
- 列出 NVMe 设备
- 读取 NVMe 信息
- 检查 NVMe 运行状况
- python模块可以：
- 读取 NVMe 信息
- 定期读取和检查 NVMe 信息（例如每秒检查一次 SMART 属性）
- 检查严重警告、热节流、过度磨损等。
- 运行自检诊断
- 创建简单的测试和测试套件
安装
pip install nvmetools
在 Linux 操作系统上，必须授予 nvmecmd 实用程序使用以下命令读取 NVMe 设备的访问权限。运行 listnvme 控制台命令，它将显示以下带有实际 nvmecmd 路径的命令。运行这些命令以授予 nvmecmd 访问以读取 NVMe 设备。
sudo chmod 777 <path to nvmecmd>
sudo setcap cap_sys_admin,cap_dac_override=ep <path to nvmecmd>
列出 NVMe 设备
此控制台命令列出具有唯一 NVMe 编号的 NVMe 设备，这是其他控制台命令所需的。
listnvme
示例控制台输出
EPIC NVMe Utilities, version 0.0.7, www.epicutils.com, Copyright (C) 2022 Joe Jones
On Window systems the NVMe number is the physical drive number.
For example, physicaldrive2 would be listed as NVMe 2.
On Linux systems the NVMe number is the nvme devices number.
For example, /dev/nvme2 would be listed as NVMe 2.
LIST OF NVME DRIVES
NVMe 0 : Sandisk WDC WDS250G2B0C-00PXH0 250GB
NVMe 1 : Samsung SSD 970 EVO Plus 250GB
读取 NVMe 信息
此控制台命令读取 NVMe 设备的信息。使用 --nvme 参数提供 NVMe 编号以指定要读取的 NVMe。例如，下面的命令读取 NVMe 0。
readnvme --nvme 0
此命令将 NVMe 信息显示到控制台并将其记录到几个文件中。控制台输出记录到 readnvme.log，详细的 NVMe 信息记录到 nvme.info.json。
默认情况下，只有一部分 NVMe 参数显示在控制台上。可以使用 -all 参数显示所有参数。可以使用 --hex 参数显示来自命令的原始十六进制数据。

此命令向控制台显示详细结果并创建摘要 PDF 报告：
nvmetools
nvmetools python 包提供了在您自己的模块中读取和测试 NVMe 驱动器的功能。nvmetools 在线文档可以在 Read The Docs 上找到。
未来扩展
本节列出了已作为概念证明实施但未包含在此版本中的可能扩展。这些示例提供了如何扩展此包的想法。
-
使用 nvmetools 和 fio 的全自动集成测试套件。该测试套件运行多个功能和性能测试，然后创建 PDF 测试总结报告。下面是一个示例报告。
-
与 TestRail 测试数据库系统集成。TestRail 网站用于在一台或多台远程计算机上启动上述测试套件。当测试套件完成时，TestRail 数据库（和网站）会自动更新结果。
-
与文件服务器集成。当上述测试套件完成后，所有日志和数据文件都将复制到充当文件服务器的 Dropbox 帐户。然后使用指向 Dropbox 上的日志和 PDF 报告的超链接更新 TestRail 数据库。
