We have IDs for a few SAN/NAS devices. It all depends on what you are scanning. If you have access to some devices you think we may not have in our database then you could request and use the ScanMachine tool from Tier III and run a quick test against them and report the results back.
You have the ability to scan any IP-based system that is connected to a network reachable by Foundstone. Custom fingerprints can be added to the product for new devices or you could leverage FSL to write a custom script to potentially identify new systems too. Don't hesitate to let us know if you have any questions.
