Questions

  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?
    • it's wwpn:wwnn. The port number comes first.
  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?

Answers

QConvergeConsole CLI

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.

LD_LIBRARY_PATH=/usr/lib64 /opt/QLogic_Corporation/QConvergeConsoleCLI/qaucli

…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
