8G Fibre Channel goes about 7.9 Gbps. 16G goes 14.1. Both protocols can push line rate to a ramdisk without having to try very hard.

FC gear is interoperable across three generations. In testing, everything was compatible and worked as expected except for 16G optics in 8G ports: those negotiated 4G connections instead of 8G as expected.

The difference in power and heat from different generations of optics is not measurable. 16G optics don't require heatsinks.

NPIV can't be done without a switch. See 2025-01-01-fc-vports.txt for how to do it if I ever get a switch.

8G gear can't speak NVMe. I didn't try it with the 16G gear yet because I couldn't stand the noise of the fans.

Download from Marvell or find it in ~/Library/hardware/qlogic-2xxx. Installing the .deb on Debian 12 created a problem for me where it couldn't find libncli.so.

…or install the RPM instead.

• 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
