To help ensure that the active memory dump is captured if a fatal system error occurs, allocate sufficient space for the page file. Dell Technologies recommends allocating at least 50 GB plus the size of the CSV block cache.
-
Determine the cluster CSV block cache size value by running the following command:
$blockCacheMB = (Get-Cluster).BlockCacheSizeNote: On Windows Server 2016, the default block cache size is 0. On Windows Server 2019, Windows Server 2022, and Azure Stack HCI operating system version 22H2, the default block cache size is 1 GB.
- Run the following command to update the page file settings:
$blockCacheMB = (Get-Cluster).BlockCacheSize
$pageFilePath = "C:\pagefile.sys"
$initialSize = [Math]::Round(51200 + $blockCacheMB)
$maximumSize = [Math]::Round(51200 + $blockCacheMB)
$system = Get-WmiObject -Class Win32_ComputerSystem -EnableAllPrivileges
if ($system.AutomaticManagedPagefile) {
$system.AutomaticManagedPagefile = $false
$system.Put()
}
$currentPageFile = Get-WmiObject -Class Win32_PageFileSetting
if ($currentPageFile.Name -eq $pageFilePath)
{
$currentPageFile.InitialSize = $InitialSize
$currentPageFile.MaximumSize = $MaximumSize
$currentPageFile.Put()
}
else
{
$currentPageFile.Delete()
Set-WmiInstance -Class Win32_PageFileSetting -Arguments @{Name=$pageFilePath; InitialSize = $initialSize; MaximumSize = $maximumSize}
}
