Hey Roland,
just noticed you said you'd virtualized. We are looking at that as an option at this point for our 2010 network upgrade. Could you(or your techie) contact me 'off list' via my email below and have a yak about how well, or otherwise, it works for you guys in terms of speed, time savings, system management etc. 
I am currently doing an infrastructure review here and would appreciate your experience with that setup.
 
Sent a copy to our techie here for his input too. He will be implementing the final product when a decision is made.
 
Kent.

A sun thin client server .. actually we could run anything on them, windoze, SLED, ubuntu etc .. They go with the little kiosk boxes that will last for decades, just plug in keyboard / mouse and away you go. Some of you saw this set in operation by NetworkHelp at the VITTA conference last year when they were running the cyber cafe computers outside the trade area. Am trying to source a mounting bracket that I heard you can use to bolt these to the backs of LCD monitors sounds like a good idea when I saw something similar with what you can do with an Apple MacMini. 

This term we are going to do a huge shuffle on our network to rationalise what is running on what hardware with dozens of vlrtual machines to juggle. Kevork gave me some good clues with his setup at Forest Hill, the other clues I got from Monash Uni. Most of them are small footprint debian linux computers, others run Win / Novell. Each has a job to do. Currently have a Sun 4150 and purchasing a Sun 7110 Unified Storage system <http://www.sun.com/storage/disk_systems/unified_storage/7110>  to host the machines. Virtualising our network was one of the most sensible things we have done in the past few years. Brave step forward but you need the right hardware in place.

Regards Roland

	Hi Roland,

	

	What is driving the Sun thin clients. Some years ago the State Library had them as kiosks running on ?Solaris, but theyve all gone now.

	G'day Colin, I might bounce your question and this reply to the eLearning and other mailing lists. Details and my contribution is below.
	
	Regards Roland

	Sorry for the off topic discussion, if there is a better forum to air it let me know Kevork. We are in the process of discussing how we are going to meet the 1:2 ratio and best work towards meeting the mandated 1:1 ratio of computer/companion devices for yr9-12 students. I was wondering if other schools are working their way through this and how you are intending to address the requirements. Below are some of the questions we are currently pondering and would be interested in your responses.
	
	What combination of desktops, notebooks and netbooks are you going to use to meet the 1:1 ratio?

	
	We will have about 180 iMac desktops (existing), and plan to buy 75 Macbook laptops, 75 netbooks and a swag of assorted thin Sun clients. For obvious reasons they will be located according to use (Sun thin clients as kiosks and 6 x 13 laptop trolleys in staff rooms and 6 x 13 boxes in library). No new labs, just filling in some gaps. Oddly enough, we reckon that we can assemble the small sets of 13 netbooks into adapted book boxes for loan from the library. Am using 13 as a working number for each set.
	

		Do you envisage parental contributions to support the program? If so, what proportion of cost is being considered? What if they don't pay? 

	
	Parents paying? Not likely ever here ..
	

		Do the students have ownership and take them home or does the school house and recharge them?

	
	Only the netbooks and only if the teacher signs them out, counts and returns them (excursion, overnight etc.)
	

		How do you plan to sustain the program after the initial purchase?

	
	Federal or divine intervention come to mind or perhaps a direct appeal to a small deity. Seriously though, if the machines start to fail we remove a class set to canabolise parts for the others. Eating our liver might seem odd but it has worked for graphical calculators to date. Kind of why the bulk of stuff we have is on a rolling lease. We have had a great experience with the robust and well built Macbooks so we are buying these up (big price fall just now!) .. and buying the cheapest cheapest for the Netbooks. Got some great cues and clues from a great school visit to Coburg SHS and talking to Principal Don Collins.
	

		How are you also intending to delivering the NSSCF requirement of 1:2 across 7&8?

	
	We are not locking the junior kids out of rooms or away from the trolleys .. that is just plain mean spirited. In practice the users can loan the gear across the curriculum and gauge how it is being used. A gentle tap on staff shoulders might be all that is needed to encourage use by a cohort.
	

		Some technical support is being provided, how do you intend to manage this?

	
	We have a good lockdown system for the iMacs with OSX (and automated reimaging), Novell Zenworks handles the security on the Windoze side, dont laugh but the lockdown Ubuntu Netbook remix with a USB key or Internet access to the home directory or Moodle is all we need for the Netbooks .. (we avoid pretending that they are anything more than just a browser / office mix hence our decision to keep them cheap cheap)
	

		We are a large school and this would mean an additional 1300 -1400 computer devices. What management issues do you see arising at your school?

	
	Electrical (get those points in now) .. trolley storage, we can put two trolleys of 13 into the footprint of an existing teacher desk. Wireless . don't hold your breath. A place to service equipment, store parts and tools. Putting in place an apprentice ICT technician and student trainee has been the best thing we have ever done! We coordinated this through a group called Apprenticeship Plus and fund it out of our existing program.

	


	Already we have compiled detailed planning notes, training schedule and established a team list with Google Docs. I would be happy to outline how this works (or further share) if anybody is interested.
	
	Regards Roland
