Hard disks drives are a critical component of your Exchange organization. Without sufficient free disk volume, neither the operating system nor the Exchange databases can function correctly. You must monitor the Exchange store statistics daily to make sure that you do not run out of disk space and to prepare to add storage resources as required. When the Microsoft Exchange Information Store service runs out of hard drive space, it logs Event ID 1113 in the application event log to indicate the problem. For more information about managing Windows Server 2003 disks and data, see the Windows Server 2003 documentation.
Checking Disk Space
Exchange Server needs hard disk space to store its databases and transaction logs. You can check free disk space by using the following methods:
- Windows Explorer Use
Windows Explorer to check for disk space on volumes that store
Exchange logs and databases. You should monitor the disk space
regularly to make sure that the
Microsoft Exchange Information Store service will not be
negatively affected because of insufficient storage resources.
Comparing and maintaining statistical information about available
disk space on each Exchange volume and expected growth of the
databases and transaction log files, helps you with capacity
planning and adding storage when the storage resources are
required. To accommodate troubleshooting and disaster recovery
situations, it is recommended that available free volume space be
equal or greater than 110% of the size of database.
- Running a script Monitor disk space by
running a script that will send you an alert message if the hard
disk space falls below 100 MB. You can find a sample script on
the TechNet Script Center Web site.
- Use Microsoft Operations
Manager Microsoft Operations Manager
(MOM) can be used to alert administrators when volume space is
constrained. For more information, see Exchange 2007 Management
Pack for Microsoft Operations Manager 2005 SP1.
