Colocation Data Center Availability : Making Maintenance Windows Obsolete

Christopher Thames, Director of Critical Facilities

Colocation Data Center Availability: Making Maintenance Windows Obsolete How can you provide critical infrastructure power and cooling systems 24x7 without increasing costs to colocation customers? Presenters will discuss the outsourced environment, which includes live UPS load shifts for maintenance, equipment faults, or UPS commissioning. These improvements allow data centers to be concurrently maintainable and fault tolerant and eliminate the issue of stranded power in the data center.

Managing Colocation Data Center Availability Expectations • What systems are colocated in a third party data center?

• What SLA do they provide for power and cooling uptime?

• Regardless of SLA, what is your expectation?

100% Uptime

More on Colocation Data Center Expectations • Power Redundancy • Power Density • Cooling System Redundancy • SLAs and Contracts • Connectivity •

Customer Experience

Data Center Power Reliability •

Utility

• Build a datacenter assuming no utility •

Generator (Backup) Power

• Lessons from Hurricane Sandy: - Fuel resupply contracts - Diesel generator oil resupply - Automated?

- Starters, Batteries • Load Testing and maintenance (later…)

Data Center Power Reliability • •

Uninterruptible Power Supply (UPS) System Designs

– Capacity or “N” UPS system – N+1: Isolated or parallel redundant • “Catcher UPS” or multiple UPS on single output bus – System plus system (2N) redundant • High capital expense, lower system efficiency –

Distributed redundant (N+∞)

• Reliability increases as system scales up

Battery Backup

– Flywheel vs. lead acid (dry and wet cell) – New technologies

UPS Innovation on the Market Today • • • • • Double versus single conversion “Efficiency” Modes Multi-module versus single-module systems Internal bypasses Plug-and-play UPS maintenance …… What else?

Improve the distribution system redundancy.

UPS Innovation on the “Topology” Level • • • • Pod-based power distribution:

constraint on customer growth

“Stranded” power: increased cost to

provider (and customer)

Low UPS power utilization:

decreased efficiency

2N 50/50 distribution: increased risk

to customer in case of failure



Better UPS topology design, better cost, better availability

Not Just Improve Availability, But Get Rid of Maintenance Windows • • • • Think outside the box Leverage traditional, yet resilient designs Mix in innovative improvements Communicate value to customers: 100% availability, even during maintenance

Example?

Building A Delivery System to Maximize Maintenance Flexibility – Eliminating Maintenance Windows

UPS Switch Point • • US Patent No. US8294297 B2 “A scalable power distribution system for a data center and methods for scaling a power distribution system…”

UPS Swith Point Initial phase installs two UPSs to support the critical load UPS A USP XFRM UDP A A/B UPS B USP XFRM UDP B

UPS Switch Point As we scale, we add UPS C and need to redistribute load UPS A USP XFRM UDP A A/B UPS B UPS C USP XFRM UDP B

UPS Switch Point Place UPS B & C in Bypass so they output same source UPS A USP XFRM UDP A UPS B Bypass UPS C Bypass USP XFRM UDP B A/B

UPS Switch Point UPS A Disconnect UPS B USP XFRM UDP A UPS B Bypass UPS C Bypass USP XFRM UDP C A/C

UPS Switch Point Put UPS B & C back into online mode, load is now A/C UPS A USP XFRM UDP A A/C UPS B UPS C USP XFRM UDP C

UPS Switch Point The critical load was NEVER offline UPS A USP XFRM UDP A USP XFRM UDP C UPS B UPS C A/C

UPS – External Maintenance Bypass with Alternate Power Source • • • US Patent No. US 8212401 B2 Redundant isolation and bypass of critical power equipment 100% uptime SLA, even during maintenance windows

UPS – External Maintenance Bypass with Alternate Power Source UPS Input Panel UIP UPS A UOP UPS Z USP Charging XFRM UDP A UPS Output Panel A/B UPS B Charging USP Batt XFRM UDP B LOAD BANK

UPS – External Maintenance Bypass with Alternate Power Source Initial condition: UPS Z offline, UPS A on Utility UPS Z Utility UIP UPS A UOP LOAD BANK

Look for a Colocation Provider with No Maintenance Windows • • • Your expectation = 100% Uptime – Make it your standard – don’t lower standards to meet colocation providers expectations (five 9’s) Choose a provider that can get you there – Design system with robust maintenance program in mind (external UPS bypass with alternate power source) – 2N+2 design? N+2 design? Tier 3? Tier 4?

No maintenance windows – No exclusions to SLA!
