Frequently Asked Questions

  1. How do customers get a copy of OpenManage Network Manager (OMNM)?

Contact your Dell sales representative for more information and complete support list.

5. How many devices can OMNM manage?

a. The total number of devices that can be managed by one OMNM server will vary depending on the size and configuration of the server on which OMNM is deployed (see the OMNM User Guide for server sizing guidelines) and on the specific OMNM features in use. However, as a rule of thumb, a fully configured OMNM server can support up to about 2000 devices. Use of resource-intensive features such as Traffic Flow Analysis will reduce that number somewhat. Note: In OMNM 6.1 we will have higher device SKU's including unlimited device support including HA.

6.  What about customer installations with more devices than a single OMNM server can support?

a. Customers with very large configurations have a few different options. An additional OMNM server could be deployed to manage the additional devices; however each OMNM server would be managed by its own browser interface. In OMNM 6.1 we will have HA (High-Availability) support.

b. Dell S&P also sells other network management products that can also manage larger environments from Dell partners such as SolarWinds, NetScout and Entuity.
c. Contact your Dell sales representative for more information.
