1 Sydney Boys High School Technology Implementation

2 Classroom and Labs

3 Classrooms Every classroom has a computer with speakers and projector connected to it. School and P&C funded Used by teachers and students Have 4 rooms with IWB but not used much. Teachers preferred having a white board they could write on and a projector to show things, rather than an IWB.

4 Labs Have following computer labs: Junior Library for general use (30 PCs) Senior Library for general use PCs (20 PCs) Shared lab for general use & programming (30PCs) Industrial Arts Lab (20 PCs) Industrial Arts Classroom (12 PCs) Music Lab with MIDI keyboards (10 PCs) Video Lab (20 PCs)

5 Staffrooms Every teacher has a computer on their desk Staffrooms have laser printers for small jobs and we have multiple photocopiers around the school for larger jobs. Papercut for print auditing: Teachers can charge jobs against different departments Students have a quota and can purchase recharge cards from office.

6 Staff ipad Trial 16 ipads were purchased and distributed to staff Hybrid model allows staff to add own apps Initial set up training and follow up sessions to showcase apps and teachers to share their experiences AirServer on every classroom computer Allows staff to mirror their ipad to projector Required a Bonjour Reflector to be configured between our internal VLANs and our Wi Fi.

8 BYOD

9 BYOD Planning began in August 2012 ICT strategic review also considered: structured rollout build up PC labs 2013 Planning documents and consultation Teachers surveyed on how they have students use DER in classroom Presented at P & C meeting for feedback SRC for student comments / concerns

10 BYOD Devices require: screen size 5GHz Wi Fi n Physical Keyboard (inc ipad + Bluetooth K/B) 6+ hours battery life Software: Word Processing (Word, Pages, Writer, etc.) Spread sheet (Excel, Numbers, Calc, etc.) Mathematical Plotting (Wolfram Alpha site or app)

11 BYOD 2014 will be BYOD for Year 9 If successful will consider extending BYOD to Years 7 8 in 2015 Will retain a TSO to manage existing DER devices and help configure and troubleshoot getting student devices on the network.

12 Server Infrastructure

13 Server Infrastructure Failover Clustering to provide highly available services Hyper V & File Share clusters Storage: Dell MD3600i SAN + MD1220 expansion 2x PowerEdge R720 64GB RAM Server 2012 Hyper V Domain controllers are on each host rather than cluster. Remote DC on Microserver

17 Remote Servers PABX Redundant AD server Provides a physical sync source for rebooting VMs & hosts. Fax Server (HylaFax) Backup BackupPC: Deduplicated files iscsi target for main backup

18 Fax Server HylaFax running on Linux (Ubuntu 12.04) Connected using a USB fax/modem dongle All incoming faxes are ed as a PDF to reception account Reduces waste paper due to fax spam Allows easy forwarding of faxes to recipient

19 TV Recording HD HomeRun connected to roof antenna and network Win 7 Virtual machine running Windows Media Centre and Remote Potato to make available on intranet Teachers can record a single show or an entire series After recording it compresses video to MP4 and copies to shared folder on network If not claimed by teacher cleaned up after 2 weeks

20 Network Infrastructure

21 Network Modernisation Why? DER fibre problems Most switches > 10 years old No gigabit desktop support No 10Gbps backbone upgrade path What : Replaced all switches over the course of four years Upgrade backbone to multi Gbps Ensure 10Gbps capability in switches Judicious installation of new fibre to improve topology

28 VLAN Segregation Previously had entire 2048 IPs on single subnet Including devices connected to school Wi Fi Had problems with large amounts of broadcast traffic dropping Wi Fi connections. Divided the IP range into 7 subnets, each in own VLAN: Servers, Wi Fi Clients, Printers, Switches 1 for each building (3 total)

29 VLAN Segregation Needed to configure IP routing on our head switch VLAN Configuration and IP Routing ip proxy arp (DEC devices with wrong subnet to talk) ip helper address <IP> (For DHCP relay to server) Required purchase of a Premium license to allow IGMP routing Some broadcast based license servers required manually added ip forward entries.
