Do I need L3 for an iSCSI SAN? I have (2) Nexus 9300 switches (no licenses installed) for a 75 user SAN.

Firstly, I know very little about switches beyond the basics and I am still trying to hire someone to help me. I did manage to get management configured and I can log into it. It appears there are no licenses installed and that the switch is strictly L2. Cisco Part# N9K-C93180YC-FX at a cost of $10,000 each which I believe will give some indication of what they are in terms of licenses. I am within the return window and I can send them back. I plan to connect them to a Purestorage flash array and I need to be sure they will work for that with no additional licenses needed. I would appreciate any guidance. I pasted some of the license command output below.
Thanks
