Compare ESXi, Ubuntu Server and FreeNAS to see which fits your needs best.
You're considering different options for your new server setup. It sounds like you're weighing between FreeNAS, ESXi, and Ubuntu Server based on your needs and experience. You mentioned preferring FreeNAS for its simplicity but are concerned about plugin limitations and reliability. ESXi offers a straightforward way to launch virtual machines and could pair well with FreeNAS for storage, while Ubuntu Server might suit your media serving needs. Your 16-core system with limited VM threads is a key factor—checking the license restrictions for each platform will help you decide. Since you have some Linux knowledge, it’s a good idea to explore those options further and consider community support or documentation before making a final choice.
Using ZFS through CLI offers similar functionality to other filesystems or RAID setups. Unraid likely provides a more effective solution than what you mentioned. It supports Docker and virtual machines, plus software RAID and NAS capabilities. For Linux enthusiasts, CentOS may be a better choice than Ubuntu. Esxi allows running FREANAS as a VM for NAS purposes, but you’d still need a RAID controller for performance. Using that setup could lead to performance or data integrity problems since ZFS doesn’t recommend hardware RAID for proper communication with drives.
I haven't explored unraid much personally. I mainly tried freenas and spent a lot of time studying zfs—it really impressed me because I have ECC memory. Note: I just learned unraid can only use one parity drive, which isn’t enough for my needs. I’m aiming for five drives with double parity instead.
