1 EXTENDING THE LIFECYCLE OF AGEING DATA CENTRES: HOW AND WHAT SHOULD DC s DO FOR RETROFITS Jonathan Price 4 th August 2015

2 KEY DRIVERS FOR UPGRADING A DATA CENTRE Capacity Resilience Efficiency Lifecycle Replacement Combina5on of the Above

3 WHAT ARE THE BUSINESS NEEDS? Initial upgrade to meet immediate business needs Final planned upgrade to deliver final capacity Capacity Resilience Standards Iterative planned upgrade steps End of lease / New DC available

4 Market Drivers Efficiency Wider Temperature Bands Data Centre Use Co- loca>on Enterprise Resilience Changes in Guidelines Cloud Services Dynamic Load Fast Deployment Standards Compliance Constantly Changing

5 DO YOU REALLY NEED TO UPGRADE AND WHEN?

6 UNDERSTANDING THE CONSTRAINTS» Timescales» Possibility of Outages» Level of existing information

7 THE OBVIOUS CHALLENGES Paralleled Systems Space Constraints Capacities of Utilities Lack of Isolation Points

8 SOME HIDDEN ISSUES Documentation Documentation» Missing or incomplete documentation» Inaccurate documentation Commissioning Technical

9 SOME HIDDEN ISSUES Documentation Commissioning» Existing systems not meeting design capacity» In-operable isolation points» Unresolved defects Commissioning Technical

10 SOME HIDDEN ISSUES Documentation Technical» Neutrals» Circuit breaker discrimination» Surge Suppression» Changes in Code & Regulations» Latent defects» Obsolete equipment» Equipment fed from multiple sources Commissioning Technical

11 SOME HIDDEN ISSUES Documentation All of the Above» Control systems» Power supplies to ancillary equipment» Non-monitored points leading to potential latent defects» Single cord equipment» IT load distribution Commissioning Technical

12 KNOWLEDGE, KNOWLEDGE AND MORE KNOWLEDGE» Understanding of existing facility is vital» Detailed site inspection» Discussion with facilities managers:» Evidence of existing facility not meeting design capacities» Know equipment defects» Commissioning data» Existing operational challenges (unsyncronised supplies from different sources)» Maintenance regimes (more risk to process if switching / operating equipment that has not been maintained supportability of equipment / spares available on site

13 KNOWLEDGE, KNOWLEDGE AND MORE KNOWLEDGE» Actual capacities based on all constraints (kw vs. kva etc.)» Verify meter readings only analogue meter may not be giving you accurate info» Where documentation is not there contractor investigation or testing to verify configuration / performance» SPOFs as a result of distribution of IT load

14 DO YOU NEED TO UPGRADE THE WHOLE PLANT AT ONCE?» Short term, do you need to upgrade at all retrocommission» Is there as simple way to utilise stranded capacity.» Due to standard equipment sizes not all equipment needs to be upgraded at once» Develop masterplan» Each step should inform the previous (e.g.. mechanical plant upgrade may increase efficiency or power factor enough to delay or even negate the need for a mains upgrade)

15 MASTERPLAN DEVELOPMENT IT Load Existing UPS New UPS Generator Mains Switchgear Cooling

16 WHICH TECHNOLOGIES WILL WORK?

17 USE OF MODULAR PLANT AND CONSTRUCTION» Provide capacity as required delay capital spend» Higher efficiency due to higher plant loading could delay upstream infrastructure upgrade» May reduce space requirements

18 CONSIDER SITE AS A WHOLE MECHANICAL AND ELECTRICAL INTEGRATION» Can be more cost effective to add new independent mechanical systems instead of augmenting an existing system» Cost of controls resilience and expansion upgrades» Cost of electrical resilience and expansion upgrades» Independent plant used for transition» Transition risk reduced on existing infrastructure» New plant probably more efficient» Mechanical plant replacement can improve power factor and may negate electrical upgrades» Consider electrical equipment with reduced cooling requirements

19 IT AND FACILITIES INTEGRATION» Avoid the management derived SPOFs» Consider the cloud environment Source en.wikipedia.org/wiki/single_point_of_failure

20 IT AND FACILITIES INTEGRATION» Avoid the management derived SPOFs» Consider the cloud environment» Consider the use of DCIM Source en.wikipedia.org/wiki/single_point_of_failure

21 DESIGN AND IMPLEMENTATION» Can you have an outage?» Potential significant cost saving» Can significantly de-risk the process but beware of hidden risks» Detailed transition plan is vital?» Transition plan will generally drive the design» If outage possible transition plan just as important to minimise outages» Transition plan revisited throughout the project» Can new permanent plant be used in lieu of temporary plant?

22 DON T MAKE THE SAME MISTAKES AGAIN» Discrimination study and match switchgear» Provide connection points for future try to make them technology agnostic» Be vendor neutral where possible» Consider adding temporary generator connection points and possibly alternative supplies to DBs feeding single cord loads» Avoid paralleled systems where possible future obsolescence and vendor lock in» Monitor and monitor some more IT load as well as infrastructure» Commission the site properly

23 CASE STUDY INITIAL CONFIGURATION

24 CASE STUDY STEP 1 New chillers provided for capacity can be used in lieu of existing chillers for transition On-floor cooling units provided with diverse supply from new generator system New generator system required for capacity utilised for transition

25 CASE STUDY STEP 2 New redundant UPS installed initially only fed from the new generators A and B static transfer switches installed one at a time so no outage to IT equipment

26 CASE STUDY STEP 2A Existing MSB and Generator can now be isolated

27 CASE STUDY STEP 3 ATSs installed on the existing chiller DB and existing UPS Input DB and generator feed removed from existing MSB ATS From Gen AT S From Gen Up-rated mains DB for on-floor cooling installed upstream of existing board. Redundant unit from existing N+1 UPS system used for back-up New MSB installed with increased capacity Old Generator System integrated with the new one

28 CASE STUDY STEP 4 New UPS Installed for Capacity ATS From Gen ATS From Gen New on- floor cooling DB
