Can you remember 1998 Networks• [The] aim is to create a private

Wide Area Network (WAN) which links all the schools with locally available resources, such as libraries and the LEA

• The strategy is ... to implement a School Server. This will authenticate users, track their activities whilst accessing the Internet, store and backup their work, provide a school with their own Intranet (internal Web site) and act as the Gateway to the Internet.

Delivering ICT as a service

North Leamington is not part of BSF (Building Schools of the Future)

BSF will require ICT to be delivered as a Managed Service – technicians employed by the school can expect to transfer to whoever wins the contract

We aim to develop a Managed Service so that we can bid for the contract (similar to RM We-Learn project)

School LAN – Upgrade required

Infrastructure surveys have found– 1997/8 hubs still in use (very slow)– New ICT added to very old switches (slow)– Wireless not working because of old hubs– Wireless interference from nearby houses

Action Plan Budget for Infrastructure survey and upgrade to replace old hubs and

switches with managed switches, as Becta recommend ICTDS can offer managed service

School PCs, Laptops & Servers

Infrastructure surveys have found– PCs still in use after 8 years (very slow)– More than 10 laptops per Access Point (slow)– No disk management so server full (slow)– Mp3 and video files in pupil areas (slow)

Action Plan Budget for 5 year hardware refresh, wireless survey and managed

wireless deployment ICTDS can advise on disk management & offer managed wireless

A Vision of 2010

2006

Devices: between 1:5 and 1:7One desktop per five pupils

Single server Wired connections Class sets of mobile devices Most learning at single location

2010

Personal Learning DeviceOne mobile device per pupil

Five times the infrastructure Wireless primary connection Some desktops in class Learning in multiple locations

Action Plan 2006/7: Virtualisation: School, Data Centre and Applications 2008/9: Connectivity bandwidth and WAN optimisation 2009/10: Wireless and mobile devices

• Servers have no local disks, so when server dies, no discs fail.

• Disks are in a SAN (Storage Area Network) providing >2,400 Gb

• More Servers and SAN can be simply added as demand increases.

Secondary School Cluster

• Each server has 8 or more cores, up to 32Gb of memory.

• This can run 10 or more virtual servers on one physical server.

• By only running 10, one server can fail withot loss of service. The system will only slow down.
