Improving Efficiencies by Integrating Data Center Systems

August 30th, 2012

Architectural Effects on Efficiencies

• Raised floor and room air tightness • Humidity control – vapor barrier • Ceilings as return air plenums • Raised floor as supply air plenums • Containment – coordination, tightness • Large areas required to reduce static

pressure and accommodate ducts and louvers

Controls

• Pressurization • Contamination – Smoke, Pollen, Diesel • Temperature reset on cooling equipment

to control Humidity. • Select controls based on type of air

management

Electrical

• High voltage distribution – 208, 230, 277V • High efficiency equipment (or Eco mode

UPS) • Take heat producing equipment out of

computer room • Let Electrical and UPS rooms operate at

higher temperatures • Lighting control

Mechanical

• Raise Computer room temperatures to ASHRAE recommendations/allowable limits

• Increase allowable humidity levels – consider cost to add humidity

• Raise chilled water temperatures • Use VSD pumps and fans to reduce power • Use redundant equipment to increase

efficiencies

Mechanical

• High efficiency economizer systems – Air – Water – Refrigerant

• Adiabatic cooling systems • Right size cooling system operation • ASHRAE 90.1-2010 code requirements

– Typical DX type units may not meet minimum efficiencies

Mechanical

• PUE varies by system and geography • Fan power is a big influence

Key Factors for PUE • System

• Location

• Operating Conditions

High

Low

PUE

Mechanical

• Hot/Cold aisle containment systems – Similar operational costs – Different control strategies – How to keep hot and cold air separated

• Doors at end of aisles • Barriers from cabinets to ceiling • Duct from cabinet to ceiling

– Consider temperature in room • OSHA limits on heat exposure

OSHA Technical Manual SECTION III: CHAPTER 4 HEAT STRESS • TABLE III:4-2. PERMISSIBLE HEAT EXPOSURE THRESHOLD LIMIT VALUE

• ------------- Work Load* ------------ • Work/rest regimen Light Moderate Heavy • Continuous work 30.0 C (86 F) 26.7 C (80 F) 25.0 C (77 F) • 75% Work, 25% rest, each hour 30.6 C (87 F) 28.0 C (82 F) 25.9 C (78 F) • 50% Work, 50% rest, each hour 31.4 C (89 F) 29.4 C (85 F) 27.9 C (82 F) • 25% Work, 75% rest, each hour 32.2 C (90 F) 31.1 C (88 F) 30.0 C (86 F) • *Values are in C and F, WBGT.

• These TLV's are based on the assumption that nearly all acclimatized, fully clothed workers with adequate water and salt intake

should be able to function effectively under the given working conditions without exceeding a deep body temperature of 38 C (100.4 F). They are also based on the assumption that the WBGT of the resting place is the same or very close to that of the workplace. Where the WBGT of the work area is different from that of the rest area, a time-weighted average should be used (consult the ACGIH 1992-1993 Threshold Limit Values for Chemical Substances and Physical Agents and Biological Exposure Indices (1992).

• These TLV's apply to physically fit and acclimatized individuals wearing light summer clothing. If heavier clothing that impedes sweat or has a higher insulation value is required, the permissible heat exposure TLV's in Table III:4-2 must be reduced by the corrections shown in Table III:4-3.

• Average Web Bulb Globe Temperature (WBGT) – For indoor and outdoor conditions with no solar load, WBGT is calculated as:

• WBGT = 0.7NWB + 0.3GT

– WBGT = Wet Bulb Globe Temperature Index – NWB = Nature Wet-Bulb Temperature – DB = Dry-Bulb Temperature – GT = Globe Temperature

Goals for openDCIM The number one goal for openDCIM is to eliminate the excuse for anybody to ever track their data center inventory using a

spreadsheet or word processing document again. We've all been there in the past, which is what drove us developers to create

this project.

Provide complete physical inventory (asset tracking) of the data center

Support for Multiple Rooms (Data Centers)

Management of the three key elements of capacity management - space, power, and cooling

Basic contact management and integration into existing business directory via UserID

Fault Tolerance Tracking - run a power outage simulation to see what would be affected as each source goes down

Computation of Center of Gravity for each cabinet

Template management for devices, with ability to override per device

Optional tracking of cable connections within each cabinet, and for each switch device

Archival functions for equipment sent to salvage/disposal

Integration with intelligent power strips and UPS devices - APC, Geist Manufacturing, Liebert, and Server Technologies. Easy to

update with OIDs for other manufacturers

Open Architecture - All built on a MySQL database for easy report building, or export to other applications

Top 10 Questions being asked of datacenter managers: 1. Are we effectively measuring power utilization in our data center(s) today?

2. What's our overall efficiency rating (PUE, DCIE, and CADE), and how does that compare to the industry norm?

3. Are we able to accurately determine which equipment is being utilized the least and/or is the least efficient?

4. Can we determine energy consumption by application, transaction, or department, and does it make sense to allocate

those costs accordingly?

5. How much is this year's technology refresh cycle expected to improve overall data center efficiency and capacity?

6. What gains did we realize (or do we expect to realize) from consolidation and virtualization of server and storage

resources?

7. Can we optimize those gains with "what-if" analyses of all available options or through other measures?

8. Where are we most likely to experience a serious limitation, and are we at risk of having a data center exceed its

available capacity?

9. How can we minimize energy consumption (and costs) in our data center(s)?

10. What will be the return on investment for improving overall efficiency in our data center(s)?

Losses in the electrical system occur at every form of transformation and over the distance in cabling. 400 – 480VAC distribution and Electrical Power Monitoring Systems (EPMS) are designed to monitor and minimize losses where ever possible.

In the recent past , the datacenter industry has responded favorably to cries from environmentalist to search for ways to improve their efficiencies. The benchmarks created have allowed the industry to better understand the waste that was generated by over designed and poorly managed datacenters. These same benchmarks are now being used to better understand the actual infrastructure required to better support the business need.

With the use a well developed set of DCIM tools, the datacenter manager will be able to commission the facility to function as designed and then recheck that facility yearly to be sure the operating parameters do not deviate from the optimal criteria developed for the facility It’s critical to be sure that when the facility is measured yearly that the facilities’ baseline never changes.

This Matrix shows that strong DCPM Tools enable the datacenter owner to better plan for capital expenditures rather than basing decisions on the DCiE benchmark. Tools allow the owner a glimps of how his facility will operate under the new conditions before implementing the change.

The approach in building a modern Datacenter… • Match to Business Demands • Be cognizant of the total costs of the facility • Understand the effective and economic lifetime

of the building systems • Monolithic “Tier X” Datacenter’s are out • Modular split Tier built in modular fashion are in • With the rising costs of energy and increasing

pressure on organizations to be more "green," implementing a DCIM and/or DPO solution is inevitable.

• Monitor, control and benchmark…
