Hi
not 100% sure but I understand the two sentence in following way:
1-year FortiCloud service with up to 200 GB storage for a single FortiGate device (activate with scratch-off card on device)
FCL-10-90801-131-02-12
1-year FortiCloud service with up to 200 GB storage for a single FortiGate device (activate with reseller contract on portal)
FC-FC-10-90801-131-02-12
Reseller contracts means for me " Partner Contract" which means the FC-FC-10-90801-131-02-12 can only be ordered for a reseller which has a " Partner Contract" (Bronze, Silver, Gold etc). The SKU has to be entered within Partner Portal (not on device). If this is done the Partner can use this SKU/Contract to add device to his FortiCloud Account.
My opinion is:
If you looking only for log storage meaning easy nothing special etc. ok you can use FortiCloud but be aware it is really limited. If you need logging special for one and more device or as a service to your customers use FAZ (FortiAnalyzer). You can install it on VMware it is easy installed and easy configured and no more problems with Disk, Flash crashes on heavy logging etc.
Hope this helps
have fun
