Questions
- How fast can the 16GFC gear go?
- Line rate to a ramdisk without even trying hard.
- 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?
- Can it use old optics and work the same way at lower speeds?
- Yes.
- Does it use less power that way?
- Can they speak NVMe?
- Can I boot NVMe?
- Does it make sense to export ZFS via NVMe instead of iSCSI?
Answers
- Use QConvergeConsole CLI. It requires installing libcli-dev.
- 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.
