我正在编写Hyper-V VM构建脚本,并希望添加一项功能来选择SSD,以便在可能的情况下优先考虑较小和最常用的VM。我首先从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但我找不到任何让我一路走来的东西所以我用WBEMTEST找到了我需要查询的类来建立SSD之间的连接磁盘和有问题的驱动器号。
点击开始 - >运行 - >类型WBEMTEST - >检查命名空间是否设置为root \ cimv2,然后单击Connect - >枚举类 - >递归 - >好。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并找到一个要查看,然后单击添加。然后显示可用的属性和方法。
以下函数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插入设备名称。这种假设最终使得这种方法不可靠,因此使用类似的东西包含一些代码进行交叉检查是明智的:
$DiskScore = (Get-WmiObject -Class Win32_WinSAT).DiskScore
If ($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/
