Excellent, thank you for clarification. Now, I hope the seller still has the licenses. Are licenses just a string of alphanumeric characters for each feature? I hope they have them, otherwise I'm not sure what else we can do. Do you see any issues with the my approach I've mentioned above?
aggregate 1 on controller 1
> 10 300GB drives: 7 data + 2 double parity + 1 spare
>> flexible volume, should be around 2TB with dedup
>>> CIFS access
Same thing on the second controller and 10 drives
Thanks for your help!
