Sydney
Boys
High
School
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.
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)
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.
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.
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
BYOD
Devices require:
9.7”+ screen size
5GHz Wi‐Fi 802.11n
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)
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.
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
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
HylaFax running on Linux (Ubuntu 12.04)
Connected using a USB fax/modem dongle
All incoming faxes are emailed as a PDF to reception
email account
Reduces waste paper due to fax spam
Allows easy forwarding of faxes to recipient
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
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

Monitoring
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)
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.
