====== Single Case Home Infrastructure ======

I need space in my office/lab. While it was kind of fun to break out all the tasks for my home infrastructure to dedicated devices (NAS, Router, Torrent Box, switch, AP), it takes up a lot of space and means managing a lot of cables. It also means that having everything UPS backed is a greater challenge.

===== The Plan =====

  * Beef up Argon hardware wise
    * Replace 1gb stick of DDR-2 with 2 x 2gb sticks (for a total for 4gb RAM)
    * Install Atheros-based Mini-PCIe chipset and antennas
  * Migrate all infrastructure services will be migrated argon
    * routing
    * proxy (Do I want to set that up again?)
    * torrent server (definitely want to set this up again)
    * NAS (already on argon)
    * AP (setup and configure hostapd)
  * Rename argon to "router" or "schi" inline with the printer being named //printer// and the entertainment computer being named //tv//.

Additional work, down the line:

  * Add [[http://www.amazon.com/dp/B000NMAZU0/ref=wl_it_dp_o_pC_S_ttl?_encoding=UTF8&colid=3V7S7HUVMXW2H&coliid=I2C45718JU6B4P|hot-swappable tray]] to argon 
  * Get 2 [[http://www.amazon.com/dp/B00B99JU4S/ref=wl_it_dp_o_pd_nS_ttl?_encoding=UTF8&colid=3V7S7HUVMXW2H&coliid=IWJF6J3XWL6G9&psc=1|4tb drives]] and format them with btrfs (setup compression, dedup, and raid 1). Later a 4th drive can be added and the system migrated to raid 5 once raid 5 is stable for btrfs
  * Get a UPS


==== Services ====

What is SCHI actually doing?

  * NAT (routing)
  * DNS (caching and local devices)
  * DHCP
  * UPNP (running upnp daemon)
  * WAP (atheros 802.11n card is bridged to the wired gigabit network)
  * RAID1 (Two 4 TB disks running BTRFS in raid1. Snapshots are in use.)
  * NFS (serving up those 4 TB and user home dirs)
  * CIFS (via samba, allowing easier access to storage for windows)
  * dyndns (script updates home.vay8.net to external IP)
  * cron (for periodic tasks)
  * ssh
  * NBD (Network Block Device, like iscsi, but simpler and easier to use)

Planned:
  * web cache
  * btsync
  * http
===== Integrating the Switch =====

I integrated the 8-port, 1 gigabit ethernet switch into the case of my NAS. I salvaged a molex power connector from a dead fan and soldered it to the power contacts on the board.

The only downside is one port is made inaccessible.

| {{ ::schi:01_switch.jpg?direct&600 |}} The switch in its case. |
| {{ ::schi:02_mounted.jpg?direct&300 |}} The switch sans case mounted inside the full size ATX case. There's plenty of room because the motherboard in place is a mini-itx. Its held in place with nuts, bolts, zip ties, erector-set pieces, a bent blank bracket, and sheer force of will. 12V are sourced directly from the PSU. |
| {{ ::schi:03_close_up.jpg?direct&300 |}} Close up external view. |
| {{ ::schi:04_in_place.jpg?direct&600 |}} The system back in its place of honor, all wired up. The perfectly cut-to-length cables no longer all fit. Cable management will be improved upon once everything has been recased. |
| {{ ::schi:05_lights.jpg?direct&600 |}} The connectivity and power lights are still visible thanks to some missing blank brackets. |
