How to manage capacity in Exchange?
GSX Monitor & Analyzer main features
Real Time Monitoring of the capacity
Administrators can have a real time and direct view of the disk capacity for any Exchange server.
This information can be useful to quickly troubleshoot a problem that seems to rely on disk capacity.
Disk Space Alert
GSX allows administrators to set up alerts on any disk attached to any exchange server. The alert is sent if the available disk space is below a certain amount of MB or percent. It allows administrators to be proactive and not to wait for a problem to fix the storage issue.
DB Store Size and White Space
Disk space is always at stake when it comes to managing the DB Stores. Capacity and storage are critical as they determine the availability of the service. Two points are critical: the DB store size itself and the white space. For both, GSX alerts if one of the two points exceeds a certain threshold. It allows anticipating any storage problem.
Real time statistics view
GSX provides several critical statistics that need to be followed at the DB level in real time:
For each server, GSX provides the list of the DB with their Content Index State, general size, white space size, number of Mailboxes on the DB, average Mailbox size, last log inspection date and the last backup date (to know if maintenance process are being made).
Trending and Forecasting
In GSX Analyzer: Multiple features and statistics per platform can be used to make capacity and disk management.
- Environmental Health is a very good way to compare capacity across servers and correlate the disk statistics with DB Store, mailboxes and so on.
- Trends and Forecasting allow administrators to make real capacity planning and to correlate disk statistics with KPIs to see the likely evolution in the future.
Statistics provide by GSX Analyzer to anticipate storage issue
- Size of the DB: Reporting on a DB size means knowing the amount of used space on the disk to anticipate capacity problems. It is a critical statistic to forecast with GSX Analyzer!
- White Space DB: If white space is constantly increasing it means that the DB is not backed up correctly and that no maintenance operation is made on the DB. That leads to critical capacity and availability problems.
- Number of Mailboxes and Average size of a mailbox per DB: Critical for sizing. Example: The architecture is set with a 5GB quota per Mailbox. The administrator can see the evolution of the size of the mailbox and compare with the DB store quota setting. The purpose is to make capacity plans in order to anticipate storage purchases.
- Number of mailboxes and number of Mailbox Databases per server: The purpose is to balance the number of mailboxes between the DB stores and the servers. Some servers can have either a small number of users and a lot of storage, and some other servers can have too many users for historical reasons. GSX allows the administrator to have a clear view and take action.
- Average mailbox size per server: Same idea of average DB size per server. Is the reality matching with the original sizing? Are there any storage problems to anticipate on this server regarding the evolution of this statistic?
- Total Disk Space usage for all Mailbox Databases (per server): Critical to make capacity planning. This statistic has to be correlated with the information GSX gives on the disk space used by the DB to detect further storage problems. GSX Analyzer Environmental Health and the Forecasting features are key points to fully exploit these statistics.
- Disk space for any Exchange server: Disk Space Exchange Data used (MB) and Disk Space Exchange Data free (MB).
