4 Agenda The Data Center Landscape Why Capacity Visibility is so Important Knowing your IT Capacity and Gaining Visibility Increasing your IT Cooling Capacity The Truth About Redundancy Management Redundancy and IT Capacity Case Study

5 The Data Center Landscape High density IT equipment stresses the cooling capacity of many data centers. Increased proliferation of IT equipment can lead to unexpected problems with power and cooling infrastructure including overheating, overloads, and loss of redundancy. The ability to match heat load and cooling resource at the rack and room level is required to ensure efficient use of the cooling infrastructure resources.

6 Data Center Challenges Managing the data center for today and future can be formidable task. Knowing your infrastructure capacities and how to manage them is paramount to success. How much IT capacity is available while maintaining Redundancy? Space Power Cooling

7 Cooling Visibility Data center managers today need more granular data for thermal environmental management Many variables lead to reduction of cooling capacity Additional IT load stresses cooling resources Amplifies Uneven Power Distribution Thermal Hot Spots Loss of Cooling Redundancy & Availability

8 What Data Centers Struggle With Power and Space capacity resources are more easily defined and measured. Cooling capacity is affected by airflow which cannot be seen Sensitive to small scale changes Lost capacity accumulates without warning as the IT configuration evolves Dynamic server environment 30% improvement in infrastructure efficiency from improved airflow management

9 Why cooling capacity management is important IT Expansion Capabilities Staying within redundancies Knowing term of life of DC When to expand or new build Controlling Operating Costs Keeping your IT Thermally Safe Overall peace of mind

10 How do we gain visibility into our data center capabilities? PDU Monitoring Server Monitoring Thermal Monitoring Building Management System (BMS) Computational Fluid Dynamics (CFD) Thermal Imaging Cooling Resource Manager Environmental Management Services

11 PDU & Server Monitoring PDU Monitoring First step in DC performance monitoring IP Addressable PDU s allow for monitoring from one machine Automated alerting Parameters: Amps Temperature Humidity Server Monitoring Software based server management Hardware asset inventory and health reporting Controls 100 s of servers at once (powering on/off based on computational load) Predictive Failure Analysis and alerting View sensor and system event logs

12 Thermal & BMS Monitoring Thermal Monitoring Real-time Visibility Accuracy based on number of sensors Great for the proactive manager Parameters: Temperature Humidity Pressure BMS Monitoring Limited capacity Very sophisticated to implement Does not natively support SNMP Allows for historical trending

30 Redundancy Management

31 What does Cooling Redundancy mean to you? Uptime Uptime Uptime

32 What is seen in DC s today Most data centers employ multiple CRAC units to keep the data center area cool. Generally, an extra unit is installed such that failure of any single unit will go unoticed to the end user. This is known as an N+1 setup, meaning N is the number of units needed to operate, and +1 denotes an extra unit is running as a backup While this design is sound, the CRAC units are not the only part of the entire cooling system that is critical.

33 Variables in Redundancy (Raised Floor) Cooling supply affected by: Plenum Depth & Pressure Underfloor Obstructions Perforated tile placement Room / Rack / CRAC Location Plenum Leakage

34 The Truth About Redundancy Having an additional CRAC does not mean that you are N+1 Redundant. Redundant CRACs can only provide cooling redundancy to the immediate area in which it s located This is further amplified if cold aisle containment is used

35 How Containment is Affected Contained zones are high pressure zones compared to the rest of the data center Requires the small server fans to pull air through the floor and into the racks Performance is dependent on closest CRAC If the contained area is far from the redundant CRAC, redundancy does not exist

36 Plenty of Cooling But Where is my Redundancy Baseline Model of a Room with very few thermal issues but does redundancy exist?

37 Don t Turn off that Unit! Baseline condition when 2 CRACs are put into Hot-Standby: Room is unable to maintain thermal safety

38 Redundancy Found and Utilized DBC Solution Implemented: All racks are adequately cooled and in compliance with ASHRAE Redundancy realized

39 Polling Question: Which of these are you experiencing in your data center? A.) Thermal Issues B.) Redundancy Issues C.) IT Growth D.) None

40 Disaster Waiting? Area is thermally unsafe CRAC #3 Fail

41 Disaster Averted! Area is thermally SAFE CRAC #3 Fail Additional Cold Air Due to Hotspotr

42 Demand Based Cooling Redundancy and IT Capacity Case Study
