ENVIRONMENT

Student expectations: devices, IT provision, Wi-Fi everywhere

Staff expectations: new technologies and approaches provide an effective IT setting… … delivered efficiently


“For changes like this to be effective they have to be much more than a rebranding or restructuring, they have to represent a fundamentally different approach to the way we deliver services, conduct our business and function as a University”

Professor Pete Downes – Principal and Vice-Chancellor

Goals and Objectives - Technical

• Replace the campus (Border routers, core switching, edge access layer in all locations including wireless), wireless and datacentre networks with consistent reliable hardware

• Improve the student experience through the enhanced consistency and availability of wireless infrastructure, covering both internal and external spaces

• Reduce the complexity in the network through revising the topology of the Campus, Wireless and Datacentre environments

• Improve the performance of the desktop and mobile applications through use of faster connections

• Improve the security posture of the University to mitigate the risk from unauthorised or incompliant devices being connected to the network

• Remove single points of failure by having vendor standard configuration that can be supported by vendor remotely or onsite



Goals and Objectives - Commercial

• Remove the requirement to invest significant amounts in capital refreshes every 5-6 years by changing to a monthly operational cost

• Remove the variation in costs of growth of network• Operationalise the network to clearly define standard changes so they can be carried

out by non-specialist staff following the strategic direction of the IT restructuring• Enter into a co-sourcing arrangement with the suppliers for the ongoing management

of the network to reduce the service and design risks



Critical Success FactorsReplace 20,000 switch ports & 1,100 WiFi Access Points

Increase the performance of wired network to > 500Mb/s.

Increase the coverage of wireless across Campus

Reduce calls logged regarding wireless access

Reduce the number of switches replaced each month

Equivalence between wired and wireless network in terms of capabilities



Pre Tender Engagement

• Met with majority of Vendors before RFQ published

• Cisco, Brocade, Dell, HP, etc.

Aims

• Ensure visibility in the market place to attract bids

• Ensure RFQ is not prejudicial

• Understand vendor capabilities

• Avoided majority of VAR at this stage - too many to deal with



RFQ Evaluation

Mixture of Mandatory and Descriptive Requirements

Intentionally very open to not limit vendor selection

Focus more on operational capability and business goals not technology

Bid writing is a skill – some groups are very good at it, others less so

Need to look beyond the polish and understand the underlying capability

Opportunity for clarification – key way to ensure clear understanding of requirements
