1. How fast can the 16GFC gear go?
   • Line rate to a ramdisk without even trying hard.
2. Does NPIV work? (Not on the first try.)
   • It fails the same way the 8GFC gear did… if we get it working here, can we get it working there?
3. Can it use old optics and work the same way at lower speeds?
   • Yes.
4. Does it use less power that way?
5. Can they speak NVMe?
6. Can I boot NVMe?
7. Does it make sense to export ZFS via NVMe instead of iSCSI?

• If you see “IO_PAGE_FAULT” in dmesg every 5 seconds, add “iommu=pt” to the kernel command line. It's probably specific to EPYC CPUs.
• The 26xx cards are perfectly happy to boot MBR drives in BIOS mode.
• The 26xx cards do not have dual personality. They are storage-only.
• The ports are BACKWARDS!!! RAGE
• Port numbers are off by 2 instead of by 1. WWPN and WWNN are adjacent now.
