So, it's about time I spruced up my home network a little. This is going to be done piecemeal, as the amount of equipment I want to buy is plentiful enough that I won't be able to afford it all in one go. I need some place to track my current plans, and a thread seems like as good a place as any.

My infrastructure domain is sjm.la and my public-facing service domain is sjm.so, which is a bit of a pun on the way shared libraries work in Linux. All infrastructure hosts on my home network will therefore have names under home.sjm.la.


bdr1.home.sjm.la (border router)

Intel Atom D945GCLF2 board (given to me for free, 45 W)
2 GB of DDR2 RAM (also given to me for free)
Antec ISK110 case ($99.00, incl. 90 W power supply)
Kingston V300 60 GB SSD ($69.00, 2 W)
OpenBSD 5.4 ($0.00)

Subtotal: $168.00, 47 W


dsl1.home.sjm.la

ADSL2+ modem (TBC)


dist1.home.sjm.la (distribution switch)

D-Link DGS-1100-08P Gigabit PoE switch ($159.00, 8 W)


wifi1.home.sjm.la (WiFi access point)

TP-Link TL-WA901ND Access Point ($49.00, 3 W)


Total so far: $376.00, 58 W


That will suffice for now. I'm going to add some more detail on my planned storage cluster later, but this is the minimum necessary to reproduce my current functionality with the flexibility of a real UNIX-like router OS.

Intel Atom? That doesn't sound very open source.

Where the hell are the Raspberry Pis?

The Raspberry Pi would suck as a router. Just wait until I post my storage cluster plans.

God dammit, Parsifal. Finally a site with graphics cards in stock and reasonable prices and it is "Australia's Premier PC Store."

Does it take bitcoins?

Irrelevant. I wouldn't order from a site in Australia as it would require international shipping, which costs upwards of $100 more than the purchase price.

Storage cluster (not including network cabling; I'll work out how to wire all this together later):


stor1.ceph1.home.sjm.la, stor2.ceph1.home.sjm.la (identical storage nodes running Ceph OSDs and mons)

Intel Core i3 4130T CPU ($159.00, 35 W)
ASUS H87I-PLUS Motherboard ($135.00)
G.Skill Ripjaws 8 GB DDR3 RAM ($109.00)
Corsair Force GS 128 GB SSD for booting, mon data and journaling ($155.00, 5 W)
5x Western Digital WD Red 4 TB hard drive for storage data ($249.00 each, 5 W each)
SilverStone DS380 8-bay NAS chassis ($179.00)
Antec EA-550 Platinum Power Supply ($129.00)

Subtotal: $2111.00, 65 W per node


mon1.ceph1.home.sjm.la (third Ceph mon node to maintain quorum when one of the storage nodes is down)

Raspberry Pi Model B ($52.28 USD, 5 W)


edge1.home.sjm.la (edge switch for storage network traffic)

D-Link DGS-1100-16 16-port Gigabit EasySmart Switch ($109.00, 12 W)


Total: $4383.28, 147 W

$4,300AUD? Really? And what on earth do you need 4TB of hard drive space for? You can't possibly have that much porn.

$4,300AUD? Really? And what on earth do you need 4TB of hard drive space for? You can't possibly have that much porn.

Look again. I'm buying 10 of those drives, and Ceph will replicate data between my two storage nodes automatically, giving me a total usable storage capacity of 20 TB.

Also, this is probably going to end up costing less than the current total, due to the fact that I won't be buying it all upfront. Most of the cost is in the 10x 4 TB hard drives, and I'm going to stagger those purchases (likely over a couple of years), over which time their price will come down.

[Thork]

When I worked at Airbus we designed an entire aircraft including all those cad drawings on less than 3TB.

What the hell are you planning to put on 20TB of storage?

[beardo]

You seem jelly, Th*rk.

[xasop]

Congratulations.

What the hell are you planning to put on 20TB of storage?

Initially, the 1.2 TB I'm using right now on my 2 TB hard drive. When I got this computer less than years ago (as I'm sure you'll recall vividly, having tried to push me towards buying various things I didn't want), I only had 200 GB. That's 1 TB of growth in under two years, on top of which I want to get back into recording music again which takes up its fair share of space.

On top of that, Ceph provides an Amazon S3-like interface for general-purpose object storage, which I'm considering opening up to the Internet to share files with people. This will be yet another data source on top of what I'm already using (which is growing at more than 1 TB every two years).

A single 4 TB hard drive is only going to last me another couple of years at this rate. A properly built Ceph cluster will last me much longer than that, as well as providing seamless upgradability thanks to Ceph's distributed and highly available nature.

If it makes you feel any better, I'm going to be building the first incarnation of this cluster on 10x 1 TB drives I'm getting for free. That's only 5 TB of storage until I start buying bigger drives.

Seems like an awful lot of power for what is essentially a home network. 
And your storage is going a bit too far.  Yes, it'll last a long time but I suspect your drives will die before you run out of space.  It would be better, I think, if you got enough to handle the next 2 years then upgrade the drives as you go.  In 2 years those 4TB are going to be much cheaper and whatever the highest level drive is going to cost what the 4 TB costs now.

In essence, you get more storage space for the same price, when you need it.

That's essentially what I'm doing. As I said, I'm not going to be buying all of this equipment upfront. This is more of an eventual goal.

Also, the 4 TB drives are already cheaper per GB than the 2 TBs, and almost on par with the 3 TB.

I've just placed an initial order for this stuff. I'll be buying more hardware for the storage cluster later.

I have installed OpenBSD 5.4 on my new home router. Next up, I need to configure it to be a router.

How did you manage to install OpenBSD 5.4 on something that doesn't exist yet?

No PfSense?

Why would you build a router when you can buy one for like $30.  They even come with WiFi built in.

He probably wants complex rule sets.
