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:

Hi Robert,

my old home server needed to much energy (~80VA) permanently, so I went for an

The manufacturer is located in Korea and has dealers around the world. Put it 
in one of their cases https://www.hardkernel.com/shop/odroid-h3-case-type-1/ 
add two drives and you will have a system that consumes less than 20VA under

will be below 250USD excluding drives.

Re: [CentOS] Looking for a RAID1 box

[Robert Moskowitz]

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.

Probably something like these:

My search foo has been really off, it seems.

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.


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
