HP MicroServer Gen8: Boot TrueNAS from an SSD on the ODD Port using a GRUB USB Bootloader
The HP ProLiant MicroServer Gen8 is still a very useful small home server. It works well for TrueNAS, homelab setups, backup targets, or compact storage systems.
A common issue appears when you want to move away from booting TrueNAS from a USB flash drive and instead use a proper small SSD.
The MicroServer Gen8 has an internal SATA connector at the top of the chassis. This port was originally intended for an optical DVD drive. It is commonly called the ODD port and is mechanically very convenient for installing a small 2.5-inch SATA SSD.
