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

I’m still yet to find a decent replacement for Google Powermeter (i’m starting to think i’ll need to write something myself… php/mySQL possibly?)

Anyway- i’ve noticed my baseline (always on) power consumption is pretty high so picked up an extension lead from maplin http://www.maplin.co.uk/power-strip-with-energy-and-co2-meter-348228 (£12.99) with a built in display (current consumption, max consumption, cumulative consumption, power factor etc) to check all of my devices to see where I might be able to realize some improvements.

Here’s what I found with some commentary:

Fish Tank Pump: 4W (Reasonable & not really optional)
32″ TV Standby: 4W (Not great but it’s normally turned off at the mains not left on standby)- On: 110W (Pretty poor but it is relatively old tech)
Sky+ Box: 20W (Appeared to draw the same power whilst in standby and whilst in use)
Clarke Tech 9000 HD Satellite Receiver Standby: 26W- On: 31W
42″ LG TV Standby: 1W (Expected for a relatively recent model)- On: 68W (Not bad considering it’s not LED backlit)
Boiler Idle: 3W
50″ Panasonic Plasma TV Standby: 20W (Very poor, but unsurprising for old tech)- On: 400W (ouch!)
Mordaunt Short Subwoofer Standy: 3W (Seems reasonable with the auto-on feature active)- On: 18W
Acer Revo r3610 XBMC HTPC Off: 3W- Idle: 32W- Watching a movie: 28W (why it uses more power when idle than whilst playing a movie i will never know?)
Mini TP-Link 5port Gigabit Switch: 2W (impressive!)
Linksys Enterprises Managed 24Port Switch w/POE : 41W (expected this- may do some research into alternatives)
4×4 HDMI Matrix Switch: 14W
Nintendo Wii Off: 3W- On: 16W
Onkyo 608SR Amp Off: 0W (impressive!)- On: 45W- Playing Loud: 55W
Netgear Router: 10W
HP Proliant Microserver in use: 40W (impressive!)
Giant American Style Samsung Fridge Freezer: 100W (pretty good from what i understand)
Dell Poweredge 2950 III Off: 30W (ouch- this is with both PSUs plugged in- i have already ordered replacement Supermicro servers which I believe use 40W roughly whilst on/idle!)- On: 350W (ouchhhhhh!)

That’s about all… We know the usual appliances: Kettle, Oven, Microwave, Toaster, Washing Machine, Tumble Dryer, Hover, Hair Dryer etc draw ridiculous amounts of power but I was predominantly interested in always on devices. I will try and add some makes/models above where i haven’t already put details. If you can recommend any green devices please do share!
