我正在编写一个 Hyper-V VM 构建脚本,并希望添加一个功能来选择 SSD,以便尽可能优先考虑较小和最常用的 VM。我首先从这里的脚本专家那里找到了方法:http: //blogs.technet.com/b/heyscriptingguy/archive/2013/03/17/powertip-use-powershell-to-identify-ssd.aspx但我不能'找不到任何让我一路走来的东西,所以我使用 WBEMTEST 来查找我需要查询的类,以在 SSD 磁盘和相关驱动器号之间建立连接。
单击开始 --> 运行 --> 键入 WBEMTEST --> 检查命名空间是否设置为 root\cimv2 并单击连接 --> 枚举类 --> 递归 --> 确定。大约 5 秒后,列表将完全填充,允许您单击列表项。单击列表项,然后按字母 W 跳转到 Win32 并找到要查看的项,然后单击添加。然后显示可用的属性和方法。
下面的函数 IsSSDDrive 返回 $True 或 $False,具体取决于给定的驱动器号(包括冒号 - 例如 C:)是否安装在固态磁盘 (SSD) 上 - 假设制造商将字母 SSD 插入到设备名称中。这种假设最终使这种方法不可靠,因此明智的做法是包含一些代码以使用以下代码进行交叉检查:
$DiskScore = (Get-WmiObject -Class Win32_WinSAT).DiskScore
If ($DiskScore -gt 6.9) { $SystemHasSSDDrive=$True } Else { $SystemHasSSDDrive=$False }
Write-Host "System Has SSD Drive: $SystemHasSSDDrive"
...如果您的环境使用此类驱动器。
Function IsSSDDrive($Drive)
# Returns $True or $False depending on whether the given drive letter (including colon - e.g. C:) is mounted on a Solid State Disk (SSD) - assuming that the manufacturer inserted the letters SSD into the device name - which ultimately makes this method unreliable so beware to cross check using something like $DiskScore = (Get-WmiObject -Class Win32_WinSAT).DiskScore # Thanks to Rens Hollanders for this! http://renshollanders.nl/2013/01/sccm-mdt-identifying-ssds-from-your-task-sequence-by-windows-performance-index/
