Exchange groups databases
together to share a set of transaction log files and this database group is called a storage group.
New to Exchange Server 2007 is the ability to have up to 50 databases distributed in up to
50 storage groups. However, there is still a maximum of five databases in one storage group.
It is a best practice to have one database per storage group. Another change from previous
versions is that the streaming database has been removed.

Some of the cmdlets that are used in working with storage groups are:
??‘ New-StorageGroup
??‘ Move-StorageGroupPath
??‘ Remove-StorageGroup
Creating Storage Groups
After installation of the Mailbox role an initial storage group will be created. Most of the mailbox management
can be done with the Exchange Management Console (EMC). One nice feature of the console is
that it will show the PowerShell command after executing the operation. The New-StorageGroup
cmdlet is used to create new storage groups:
New-StorageGroup -Name < String > -Server < ServerIdParameter >
[-CircularLoggingEnabled < $true | $false > ] [-CopyLogFolderPath
< NonRootLocalLongFullPath > ] [-CopySystemFolderPath
< NonRootLocalLongFullPath > ] [-DomainController < Fqdn > ] [-HasLocalCopy
< $true | $false > ] [-LogFolderPath < NonRootLocalLongFullPath > ]
[-SystemFolderPath < NonRootLocalLongFullPath > ] [-TemplateInstance
< PSObject > ] [-ZeroDatabasePages < $true | $false > ]
New-StorageGroup [-Name < String > ] -Recovery < SwitchParameter > -Server
< ServerIdParameter > [-DomainController < Fqdn > ] [-LogFolderPath
< NonRootLocalLongFullPath > ] [-SystemFolderPath < NonRootLocalLongFullPath > ]
[-TemplateInstance < PSObject > ]
The LogFolderPath and SystemFolderPath parameters set the location of the log and system files for
the storage group.
