I do have the same question by why not SilverPeak also?
Without reviewing your MIB OID's I cannot confirm if these already exist in the Orion MIB database, but the concepts are very straightforward:
1. If the MIB OID definitions are not populated in your Orion and you are NOT running the latest Orion version release, download the latest MIB file from the customer portal and apply to your installation. If they are still not within this update, then:
2. Provide the MIB file to SolarWinds support who will add this to the MIB definition file, which you can then download from the customer portal - Upload MIB in Orion Universal Device Poller - SolarWinds Worldwide, LLC. Help and Support
3. It is not actually necessary to have a compiled MIB within Orion. If you have the OID, simply enter this into the OID field in the UNDP utility, manually define the settings (GET, GET NEXT etc.). Defining the OID and how to collect and process the data will allow this to be stored and used as normal
4. You may also need to adjust the native pollers to allow the Vendor and Machine type values to be correct and to collect the correct CPU and Memory values - Create Custom Pollers in SolarWinds Network Performance Monitor (NPM) - YouTube & Configure Vendor/Machine type when Orion is unable to detect it - SolarWinds Worldwide, LLC.

I hope this helps.
