It will go into my rack cabinet so I COULD do a 1U format.

I would prefer something sitting on a shelf in the rack (next to my QNAP NAS) about the size to handle 2 HD and system board.

Enough memory for Centos and the mail server software.  Perhaps 2Gb is enough?  4Gb nice to have (anti-virus could eat up memory at times?)

Oh, has to be Intel not ARM (iRedMail req)

I don't need hot swap.  I just did a drive replace on my QNAP and it took ~10min to power down and swap drives.  Took 10hr to mirror to the new drive.

I DO want it all in the box.  No external drives.

And I don't want to build my own hardware.  I want to buy it, install drives, attach boot ISO, and install away.

Low power like 40W or less good.

This help?

It depends on the structure of the drives.  Do you want a dedicated controller card or is an embedded card on the motherboard acceptable?

Entry Level Dell Poweredge T150 servers could work, or build your own rig with an SLI MegaRAID or HighPoint RocketRAID dedicated controller card.

There are configurations like this in a Rackmount configuration, tower configurations, or Mini Server configurations, it all depends on what kind of space / budget / environment it is going in.

Reply back with more details if you want a better answer.

I am looking for a box I can drop Centos or one of the spinoffs that:

Has RAID1 internal (not an external USB RAID thing)     Can be software or hardware

small (4TB/drive fine) and low power

I plan to use it ONLY for email server.  perhaps iRedMail

I have spent a lot of time looking and not finding any such piece of metal.

All I find are NAS boxes with their own OS.

thanks

All modern Linux kernels include software RAID out-of-the-box. This means any system that supports more than one disk that you can install Linux on (including CentOS) can be set up with Linux software RAID. If you want hot-swap, there are various SATA hot-swap units than can be mounted in a ATX case with front 5" or 3" spaces. A modern ATX motherboard with a AHA SATA controller will support Linux, including hot-swap SATA disks, including SATA connected SSDs.

Well what I am finding looks like it will be in the +80W range and I am trying to use less electricity.  I would put up with 40W, including drives.

ITX board most likely?

And will I end up needing 3 drives or does mirroring the OS partition work.

You might want to consider a Raspberry Pi 4 with 8GB RAM and a case that will support a couple of 2.5in SSD drives. I'm running one here with postfix, courier-imap, clamav, amavisd, ... Mine is in an Argon One case with single 2TB SSD with a PoE Splitter. It's running the same email software that we run on CentOS and AlmaLinux. Current uptime on out main mail server is 362 days.

This case has space for 2 2.5in SSD drives.

Just search for a 2-disk 1U x86_64 (Intel or AMD) system that has room for 2 SATA drives (probably a pair 2.5" SSDs). Don't bother to search for RAID.

Probably something like these:

After a lot of hours searching, here is what I am coming to....

3.5" 2-bay standard built just does not exist these days.  Pretty much everything is at least 4-bay.

the HP Proliant gen8 looks like a good deal, and only use 2 bays. Some models have RAID1.

9x9x10 case, not too bad.

The 1U setups end up being more as they expect them to be used for big servers.

Or I head over to Microcenter tomorrow (have to go anyway for a few items, 8mi away) and see what we can build.  They have a few 2-bay boxes.

One "enticing" aspect of the gen8 is one pair of drives, 1Gb, for the OS and another pair for the mail.

It's not just you.  I was recently searching on Google and I couldn't find what I was looking for.  I kept getting that annoying blue fishing monster.  I then went to Duck Duck Go and got what I was after.  On returning to Google and using the same exact search phrase that was returning nothing prior, I then got the same hits as on Duck Duck Go - go figure!!!

My new system is just doing its job, the whole thing will be below 250USD excluding drives.

That has 2x 2.5 Gbps ports, which would be nice for a simple home router. Is there a 3x or 4x 1 Gbps version? I was considering a Firewalla with 4x 2.5 Gbps ports, as I have two ISPs for redundancy. (One is 1 Gbps symmetric.) But they're about 2.5x that price. Review:

Robert,

I have a few hardkernels and I was the one that got Centos-arm working on them and booting completely off the HD. Problem comes back to it is ARM. I have their Odroid HC4 for doing RAID, but could not get any Linux but theirs installed.

The HC4 should be running with https://www.armbian.com/odroid-hc4/, although this would be Debian based.

And as I mentioned, iRedMail does not support ARM. So I am looking for something x64ish.

the H3+, just like the complete "H" series is Intel based. The H3+ uses a "Intel(R) Pentium(R) Silver N6005" CPU. I have it running with RHEL9
