• University of Leicester Project Brief
• DCIM explained
• Industry focus and research
• Our DCIM offering
• Core functionality
• Virtualization!
• Closing notes and next actions
Agenda
• Centralisation of High Performance Computing
(HPC) across the University
• Creation of Research Computing Team to
support the new service
• Construction of new Data Centre to
accommodate consolidated hardware
• 30 racks with up to 30kW per rack position
• Scalable from 150kW to 300kW IT load
• N+1 resilience
• Modular high efficiency UPS
The Project
“The university recognised
the importance of
efficiency, so wanted a
facility with an annualised
Power Usage Effectiveness
(PUE) of less than 1.5.”

Haven’t we come far…
… and now we understand so much more
Data Centre Infrastructure Management (DCIM)
Data Centre Infrastructure Management (DCIM) covers the integration of the physical M&E
infrastructure (Facilities) with the technology infrastructure (IT), to centralise monitoring,
management and intelligent capacity planning of a data centre’s critical systems.

Analyze
• Monitor everything
• Design it that way – you’ll never add it later
• Monitor for function / failure / alerting
• Monitor for performance / optimisation
• Monitor to understand what it’s doing
• Monitor for service cost
University of Leicester – what to monitor and why?
A single solution for all monitoring?
• Not yet…..
– A single product won’t do all of this
• Data centre infrastructure - APC ISX Central
– Proprietary, easy to use, access for Keysource
• General server, network monitoring – OpenNMS
– Free, network & server, customisable
• Specialist HPC - Bright Cluster Manager
– Proprietary, monitoring & management

Trouble
OK, taking action!
Everything, everywhere
• We can demonstrate what’s possible
– PUE of <= 1.2 without need for new build
– Rack density of >20KW without water to racks!
– Rack densities do not need to be predetermined
• We have better data to inform decisions
– Power saving features in blades are better than servers
– Investment in an efficient data centre is worthwhile
How does it help others?
• Key to securing the University’s position as a
leading research institution
• HPC service has high utilisation with users from
nearly 20 departments from astrophysics, through
genetics to economics
• Has changed the view of researchers demonstrating
that centrally provided services can benefit them
• PUE for last 30 days just 1.17
• Electricity saving, compared to old efficiency, of
approximately £140,000 per year
A successful IT project
What does it REALLY mean?
“This will strengthen
Leicester's position as an
international leader in
computational
astrophysics.”
