He discusses the entire process from why we went v6-only, selection of DHCP server and network boot loaders, through installing CentOS on hosts, and all of the gotchas along the way.

If you have Mellanox ConnectX-3 or ConnectX-4 NICs in your servers, I discovered it’s possible to do IPv6 OS installations via PXE. FlexBoot is their on-board PXE implementation that ships on their NICs and it’s based on iPXE. It turns out that as of FlexBoot version 3.4.718 from January 2016 they’ve added beta IPv6 support. […]

I wanted a new Avoton motherboard for my OpenIndiana home NAS with lots of on-board SATA so I could use the PCIe slot for a 10-gigabit NIC. I needed seven SATA ports, six for the data disks and one for the OS drive. The standard mini-ITX configuration seems to max out at six, and I […]
