I am using dell ome for monitoring of dell vrtx and i want to use dell repository mgmt and support assist as well. Do i need license for these three modules?
If license needed what extra functionality i will get and without license what feature i can use.
No you don't need a license for monitoring or support assist or repository manager. The only part that is licensed is the Configuration part in OME. For this you need to buy a license.
So for monitoring, upgrading, inventory, reports what so ever, it is free to use.
