NOTE: If the IP address of the new OMIVV version y is changed from the OMIVV version x, configure the trap
destination for the SNMP traps to point to the new appliance. For 12th and later generation servers, the IP change is
fixed by running the inventory on these hosts. While running the inventory on 12th generation hosts, if SNMP traps
do not point to the new IP, those hosts are listed as noncomplaint. For hosts earlier than 12th generation that were
compliant with earlier versions, the IP change is displayed as noncompliant and requires you to configure Dell EMC
OpenManage Server Administrator (OMSA). To fix vSphere host compliance issues, see Running the fix noncompliant
vSphere hosts wizard.

Setting up Network Time Protocol servers
You can use Network Time Protocol (NTP) to synchronize the virtual appliance clocks to that of an NTP server.
1. In the APPLIANCE MANAGEMENT page, click Edit in the NTP Settings area.
2. Select Enabled. Enter the host name or IP address for a preferred and secondary NTP server and click Apply.
NOTE: It might take around 10 minutes for the virtual appliance clocks to synchronize with the NTP server.
Configuring deployment mode
Ensure that the following system requirements for the desired deployment modes are met:
Table 2. System requirements for deployment modes
Deployment modes Number of hosts Number of CPUs Memory—in GB Minimum Storage
Small Up to 250 2 8 44 GB
Medium Up to 500 4 16 44 GB
Large Up to 1000 8 32 44 GB
NOTE: For any of the mentioned deployment modes, ensure that you reserve sufficient amount of memory resources to the
OMIVV virtual appliance by using reservations. See vSphere documentation for steps about reserving memory resources.
You can select an appropriate deployment mode to scale OMIVV to match the number of nodes in your environment.
1. In the APPLIANCE MANAGEMENT page, scroll down to Deployment Mode.
The configuration values of the deployment mode such as Small, Medium, or Large is displayed and by default, the
deployment mode is set to Small.
2. Click Edit if you want to update the deployment mode based on the environment.
