Tomorrow when I'll come to the office I'll remove two of the fours disks and I'll re-install PfSense in ZFS mode, I prefer to remove the hardware which I don't need to take care them in a drawer!

Let’s put my 5c on this:

• x3550 M2 are old, but sufficient machine for pfSense, especially You give them 2 x Xeon X5690 (same stepping and version! + GREAT thermal grease!) and 24Gb of 1.333 ECC RAM (Hynix, Micron, Nanya…) AND switch OFF ALL unused hardware (except DVD/CD) and COM port sharing/redirects;

• not forgot to FW update ALL (IMM -> uEFI -> DSA -> RAID -> backplane -> HDD -> onboard NIC) from IBM Support web System x3550 M2, 7978
  FW UPDATE ARE IMPORTANT!

And better to replace HDD on SSD (better to set 2 in mirror as system and other 2 in mirror as for system logs exclusively).

And this hoarse able to grinding 5Gb traffic with Suricata/Snort + bunch of FW rules, VPNs and shapers… ;)

You may sure that this x3550 m2 working for You next 5-8+ years.
(Just buy 1 x EXTRA PSU (power supply unit) for hot-spare change if one of old would die because capacitors die.)

I totally agree with you, I have other three PfSense (two 2.6.0 and one 2.5.2 which I should upgrade) and the hardware configuration is like what you said!

Tomorrow when I'll come to the office I'll remove two of the fours disks and I'll re-install PfSense in ZFS mode, I prefer to remove the hardware which I don't need to take care them in a drawer!

Generally pfSense works better without hardware raid controllers in my experience. If you want to use raid using two disks in a ZFS mirror.

Thanks for you reply! :)

I tried on https://ibb.co/YtbMRrb to use "Auto (ZFS)" but I had a boot loop and the o.s. wasn't load!

Now I could choose from BIOS (Legacy) and UEFI, maybe you read what happened at the end of the installation by UEFI and I don't know if that "issue" could be a problem during the f.w. using, could/should try with Legacy option or https://ibb.co/ZLkQx4P is not a problem?

I would personally choose ZFS on a large disk like that. The snapshots feature ZFS offers can be invaluable.

I solved the issue, these are the steps:

1. Partitioning
2. Partition
3. Partition Scheme
4. Partition Editor
5. Initializing
6. Issue
7. Finished

Now after the first reboot PfSense is loaded but before I start to configure it I'd like to know if I choosed the right steps here below my dubts:

• Should I choose Legacy (Auto UFS BIOS) and not UEFI (Auto UFS UEFI) installation?
• In the partion scheme should I choose BSD or GPT?

Maybe you saw the errors at he point 5 and 6 but automatically the system finished the installation and I think these are not problems but I don't know for the use of the f.w. in the future ...

But yeah, more info needed on the boot failure and possible errors.

Where does it actually fail to boot? What error is shown?

I assume it boots the installer correctly and the install itself completes without errors?

What target drive did you install to?
