Home Architecture

Une version Française de ce post est disponible.

Here is my current (at this post date) home architecture.

LANs

onsen.lan

The onsen (温泉: "hot spring") LAN is my main LAN.

It has the following hosts:

• iku is my ISP wireless router firewall.
• shōji is my wireless repeater.
• ryokan and uchiyu are my main servers.
• ofuro is my NAS server.
• ichibetsu is my security camera.
• buro is my good ol' desktop.

Friends and room mate connect to either shōji or iku to access both local resources and Internet depending on their location in the house.

teien.lan

The teien (庭園: "garden") LAN is not set up at the moment.

kabuki.lan

The kabuki (歌舞伎: "The art of singing and dancing") LAN has the following hosts:

• aho (あほ: "Idiot") is my ISP media player, we use it mostly to watch the TV... when we watch it.

neko.lan

The neko (猫: "cat") LAN is not set up at the moment.

Hosts

Network items

iku

iku (行く: "To go") is my ISP all-in-one wireless router firewall.

It is a Freebox Server Revolution from Free.

Not much to say on it. It does what is does, and I only use it for its network and gateway capabilities:

• 4 x 1000 Base-T Ethernet
• Wi-Fi 802.11b/g/n 2.5GHz
• ADSL2+ (19.2Mb/s, 1.1Mb/s)

shōji

shōji (障子: "Bamboos barrier") is my TP-Link AC1750 Wi-Fi Range Extender.

As a Dual Band Wi-Fi repeater with simultaneous 450Mbps on 2.4GHz and 1300Mbps on 5GHz, it allows me to enjoy my wireless network from all the floors of my home.

Servers

ryokan

ryokan (旅館: "traditional inn") is one of my two main servers with uchiyu.

It is plugged to our TV and is our kind of living room media station.

Nevertheless, as a main server, it endorses also many service roles: DNS server, DHCP server, Docker manager node...

Specs

uchiyu

uchiyu (内湯: "indoor bath") is one of my two main servers with ryokan. It is the backup node and handles fail over when ryokan goes down. It is also an active member of any services clusters defined with ryokan and ofuro.

Specs

ofuro

ofuro (お風呂: "bath") is my Synology DiskStation DS918+ NAS.

I chose this name because I pour out most of my data in it.

Not only it serve as NAS, but it also helps ryokan and uchiyu by participating in some services clusters.

Specs

Storage Pool

The storage pool is a 8TB RAID 6 with the 4 drives (No Spare).

I chose to use a RAID 6 (2 Data disks, 2 Parity disks). You may think that it is a bit overkill, but I want to store my data reliably, put it to safety.

If one of the 2 data disk fails, there is a possibility that one of the parity drive also get faulty while reconstructing the RAID volume. Stress is put on the array disks during rebuild: lots of data, lots of time, much danger, such risk of failure. But wow: RAID 6 protect my data even if two disks fails at the same time.

And trust me, if this moment ever happens, I would rely on my backed up data: RAID is not a backup strategy!

I split my data on some logical btrfs formated volumes:

• To install various Synology applications
• For users miscellaneous data
• For Photos / Videos
• For Music
• For Movies
• For virtualization data
• For surveillance data
• For user shared data

Others

buro

buro (風呂: "bath") is my old multipurpose desktop.

I chose this name because it's my comfy desk / chair / double - 24" screens setup. I am mostly on it when my room mate needs to use TV, that I want to put on some music while coding or play some loud games.

Specs

ichibetsu

ichibetsu (一瞥: "a glance") is my security camera to look after the cats when roaming.

It has night mode, motion detection, everything unnecessary therefore essential.
