Tag Archive: D-Link


I have been making a lot of changes the network recently so thought it was time to sketch it out:

The left hand stack is housed in the A/V rack/closet and the right stack is housed in the garage rack. To clarify a few points:

  • The two switches are linked using a 2 x 1 gigabit fibre trunk
  • The ESX servers and file servers are connected to the switch using 2 x 1 gigabit ethernet trunks
  • There ET9000, XBMC, Apple TV 2, HDMI Matrix and Sonos devices can all be controlled from smartphones, pcs etc
  • The ET9000 records to the file server
  • The Sonos Connect / ZonePlayer 90 is connected to the Onkyo Amp to allow Sonos to output to my home theatre
  • The Sonos Connect / ZonePlayer 90 is connected to the Apple TV to allow streaming from iTunes/iOS devices to all zones
  • I haven’t bothered to include my router, wireless access points, client pcs, smartphones, printers and various other devices in the diagram

The wireless sensor network provides:

  • Whole house power consumption currently using a CurrentCost EnviR
  • Individual appliance power consumption (currently monitoring 6 appliances using CurrentCost IAMs)
  • Environment information (temperature, light, humidity) using Jeelabs Jeenodes in multiple zones

This is a good reference point for where I’m headed (not much progress since I last listed but alas, still the way forward):

  • Further appliance monitoring and more importantly control (potentially through upcoming project/device: HexaBus – https://github.com/mysmartgrid/hexabus/wiki or plugwise – http://www.plugwise.com/idplugtype-g/)
  • Security cameras (and doorbell integration)
  • Environmental information (I have pulse counters for my gas meter and water/central heating system that need installing)
  • XBMC hardware replacement (once the Raspberry Pi – http://www.raspberrypi.org/ is available to buy I’d like to replace my Acer Revo)
  • Home Automation Hub replacement (once the Raspberry Pi is available to buy I’d like to try Domitiga – http://www.domotiga.nl/ or my own custom solution)
  • Web Interface (to bring all of the information together from the wireless sensor network, along with the state of all network devices (from bandwidth to free space etc) and most importantly allow central control- so instead of me having to use different methods to switch on the ET9000, change the channel on the HDMI matrix, power on the amp etc, I can do it all with one button)

As usual- I imagine I’ve missed a few bits out from the above but it hopefully provides a good overview of my network.

Happy New Year

Just about to set off on what is set to be a mammoth night with the Kool Kids Klub @ the Sunrooms: https://www.facebook.com/events/295464730481459/

Been busy today:

Setting up the new D-Link switch DGS-1224TP: Well impressed with how it compares to the old Cisco / Linksys SGE2000P.

D-Link / Linksys
Weight: 3.4 Kg / 5.8 Kg
Power Consumption (idle): 24 W / 42 W
Depth: 21 cm / 37.5 cm

I think it’s quieter too but don’t have a way of measuring it!

Installing the new RAM in the file servers: both the HP Microservers (running WHS2011 and FreeNAS 8) now have the maximum 8 GB RAM.

Finishing my first iPhone app: It’s not pretty and it certainly won’t be submitted to the app store, but it serves a purpose!

Currently I have a handful of devices on my A/V cabinet in the living room all of which can be controlled with apps on my iPhone. Unfortunately the HDMI matrix which sends the signals around the house doesn’t have a remote app… it does now :)

Still tons to do… I really need to do all the structured cabling and mount the comms cabinet with the new switch before going back to the office next week but that’s somewhat optimistic.

Happy New Year!

A few small updates

A few small updates as I have a ton of projects on the go at the moment.

FreeNas 8

After a friend visited earlier in the week I decided to give FreeNas / ZFS another shot- so I’ve installed the latest v8 on a spare HP Microserver N36L. The little cube has 4x 1.5TB Samsung disks in RAID-Z with a single 4GB stick of RAM. I have ordered another stick of RAM and a low profile, dual-port, gigabit pci-e network interface card (nic)- the HP NC360T (intel chipset) so I can setup load-balancing/link aggregation/LACP. I starting copying some data off of the current production Microserver (WHS2011):

Performance seems average. I’d expect to see a bit of an improvement when the gigabit HP / Intel nics arrive.

New Orders :)

I have put my Cisco SGE2000P 24-Port Gigabit managed PoE switch up on eBay as it’s a bit too big and loud for the small data/comms cabinet I bought recently. As a replacement I have ordered the D-Link DGS-1224TP which appears to offer the same feature set at half the size and half the weight (I think it may also be passively cooled and is touted as being "green" so hopefully help with the leccy bill :)

I also have a few Sonos S5 network wireless hifis on order (they were on special offer and I’ve been looking at whole house / multi-room audio distribution solutions for a while). I have a slight concern I may need to buy some Apple AirPort Express access points to enable AirPlay on them but I’ll cross that bridge as/when…

Apple Programming

I’m learning xcode / cocoa / objective-c / osx / iOS whatever they call it as I want to write a little app to control my 4×4 HDMI matrix. The device is on the network and supports simple commands using a telnet style socket connection, so I’m hoping it won’t be too tricky! Unfortunately I couldn’t find the old control software I had or documentation but eventually stumbled upon the pdf with a few pointers. So the reading begins… http://developer.apple.com/library/mac/#referencelibrary/GettingStarted/Learning_Objective-C_A_Primer/_index.html#//apple_ref/doc/uid/TP40007594
