目的：实现自动获取vSpherec存储容量元数据，便于对容量的预测分析
代码：
#添加信赖
add-pssnapin vmware.vimautomation.core
Connect-VIServer -server Vsphere_IP -Protocol https -User Username -Password User_password
$time=Get-Date -Format "yy/MM/dd-HH:mm"
#获取共享存储，可以使用正则匹配想要获取的存储信息的Name
get-datastore |where {$_.name -match "storage_name1"}|Select-Object Name,FreeSpaceGB,CapacityGB |Export-Csv -Append C:\storage1.csv
#获取联想存储
get-datastore |where {$_.name -match "storage_name2*"}|Select-Object Name,FreeSpaceGB,CapacityGB |Export-Csv -Append C:\storage2.csv
$time |Out-File -Append C:\storage1.csv
$time |Out-File -Append C:\storage2.csv
Disconnect-VIServer -Confirm:$false
