Data Centre: Airflow

1/5

Create an efficient data centre.

Data Centre AirflowIt is estimated that 50-80% of valuable conditioned (cooled) air does not reach the intake of IT equipment due to unsealed floors and openings.

Before After• Hot/Cold Aisle Containment• Fill Air Voids• Floor Tile Alignment• Cable Management• Server Fan Direction

Data Centre Airflow40% Annual Energy Savings in AS3 Data Centre, with more savings attainable.

Ambient temperature drop from 24 °C to 16°C

Change of 8 degrees

Lowered Air Conditioning demand to raise temperature back to 24°C

Estimated 40% Annual Energy Saving

Further 2°C change estimated!

Savings paying for HPC Chiller!

Audit Visitor Access : Who, What, Why?

Data Centre AccessNovember 2015 - New Access Policy ImplementedFully audited trail for Data Centre Visitors

Data Centre AccessJanuary 2015 - Draft copy of Data Centre Out Of Hours Access form.

Data Centre: Moves, Adds, Changes (MAC’s)

3/5

Audit and increase visibility for changes within the data centre.

Data Centre MAC’s2015 - New Policy Created

Data Centre: Safety

4/5

Ensure a safe working environment.

Earthing & BondingA server rack with 8 servers generates 10 mA-20 mA leakage currents – 50 mA is enough to kill.

Organised the appropriate earthing and bonding of each rack in AS3 DC.

Liaised with external Electricians

Organised access

Ensured job was completed without downtime

Each network rack now has the appropriate earthing ensuring a safe environment.

Data Centre: Cabling Refresh

5/5

Rework the way data cabling is connected.

Cabling Refresh“The decision to place network data and power cabling into overheadcable trays can lower cooling fan and pump power consumption by 24%.” Schneider Electric

Under-floor cabling contributes to energy losses in three ways:

• Blockage of air due to cables

• Bypass air from rack cable cut-outs

• Bypass air from (PDU) cut-outs

Liaised with external contractors

Organised access

Ensured job was completed without downtime

Each rack now has 24 port copper and fibre patch panels back to one central location.

Data Centre: Miscellaneous

Managed PDU RolloutFully managed Power Distribution Unit (PDU) solution

Rollout of managed PDU’s.

Liaised with equipment owners

Document Ownership

Plan Suitable Downtime

Label Commando Sockets / PDU / Fuse

Each network rack now has at least two fully manageable PDU’s.

LightingEfficient lighting system installed

Organised the install of new lights and emergency lighting in AS3 DC.

Liaised with external Electricians

Organised access

Ensured job was completed without downtime

PIR System implemented

20 minute no presence timeout.

High Performance Compute (HPC)

HPCUniversity invested £2M+ in owning a High Performance Compute facility

Preparation

Rigorous room planning and preparation for new contained area to accommodated HPC equipment.

Installation

Organised work and ensure contractors adhered to our standards working within a live environment.

Implementation

Worked with all parties to sign off project and assist in the handover to the HPC Viper team.

Disaster Recovery (DR) Room

Backup DR SiteConvert an old computer room into a data backup site to house 300k worth of hardware.

Preparation

Room required clearing of old equipment, furniture & general mess.

Air Temperature

Old Air Condition unit was running insufficiently and would not cope with increased load in room.

Power

Source, order, install & configure UPS

Uninterruptable Power Supply (UPS)

UPS ReplacementReplace old UPS with new more efficient system

Preparation & Planning

Planning for space, power and cooling efficiency

Installation

Organised work and ensure contractors adhered to our standards working within a live environment.
