Chelsio T62100-CR

Hello,
Make sense to buy a refurbished Chelsio T62100-CR in 2024 instead of Intel E810 (for example)? Chelsio is PCI 3.0 and not sure if all new tecnologies are available (RDMA, NVME over TCP, etc). Now I have a Core with 10 GbE server for ISCSI target for Windows 11 Initiator. I would like to upgrade to 100 GbE (in Core the ZVOL exported in iscsi is on a pool made of 6 NVME disk (3 vdevs))
Best Regards,
Antonio
