7 Best Practices
7.1
Disabling Hyperthreading
Disabling hyperthreading on the Operations Manager server can substantially improve its
performance.
The following procedures may vary, depending on the vendor:
performance.
The following procedures may vary, depending on the vendor:
1. Enter the BIOS Configuration and Setup screen by powering up the server and
pressing F1 during system startup.
2. Go to Advance Setup > Advance Processor Option > Hyperthread.
3. Select Disabled.
4. Press ESC, to return to the main menu.
5. Select Save Settings, and press Enter.
6. Select Exit Setup, and press Enter, to continue the reboot process with

6. Select Exit Setup, and press Enter, to continue the reboot process with
hyperthreading disabled.
7.2
Server Maintenance
A test with a 16-hour polling cycle and a 1-minute sampling interval uses approximately
60 to 100 KB per day. A path echo test with a 16-hour polling cycle, a 1-minute sampling
interval, and 12 hops uses approximately 1.2 MB per day.

7.3
Cold Standby/Redundant Deployments
You can use two servers and achieve a cold standby configuration. One Operations
Manager server is used as the active server and the other server is left on cold standby
and periodically synchronized with the active server using the servers DCRs. When the
active server is taken offline, the cold server will have an up-to-date inventory and can
quickly be made active.

7.3.1 Preparing for Redundancy
This section describes some pre requisites for redundant OM configurations.
The first step is to have two identical servers available for configuration. One server
acts as “Active” and the second a “Standby”. Please refer to the OM installation guide
for the hardware specification of these servers.
