Disaster Recovery: The New Imperative

March 2012

By: Clemens Pfeiffer, CTO


The Purpose of a Data Center

Provide IT equipment a healthy environment to guarantee application service levels


Data Center Requirements

• Reliability

• Required levels of power & cooling

• Support for future growth

• Service level guarantees

• Tier Definition:– 1: Non redundant– 2: N+1, redundant components– 3: 2N, active/passive– 4: 2(N+1), fault tolerant


Today’s Typical Data Center Setup

• Tier 3 or Tier 4 Data Center– Redundancy within the data center

• At least 2 redundant data centers– Redundancy across data centers

• Hot/Hot or Hot/Cold application failover configuration– Redundancy of the application

Is This Sufficient?

Is It Efficient?


Disaster Areas

Running out of power

Physical damage

Hardware and

software failure


Disasters - People Can’t Get There

Natural Disasters

•Tsunami in Japan

•Earthquake in New York

•Hurricane on East Coast

Impact

•No power for a week

•No refueling for generators

Results

•Data center failure when backup generation runs out


Out of Electricity - Out of Fuel

• In a 7 day electricity outage – delivery vehicles run out of fuel

• Diesel generators run out of fuel, as no supply is available


Demand Response / Rolling Blackouts

• Required power reduction

• Temporary outages

• Limited hours for generators

• It can happen everywhere and at all times

• Heat waves, snow, hurricanes, water


Cooling failure

• ASHRAE Limit 80.6F

• Physical Server Limit 95F

• What about 102.5F and more?

– Servers shut down– Cabling problems– Outages


Failover does not work

• Primary site down

• Secondary site not coming up

• People take actions

• Manual recovery

• Delays and service outages

The Key: Minimize the Application Risk

• Focus on application reliability NOT physical reliability

• Real-Time monitoring across facilities and IT

• Define Service Level requirements for applications

• Remove obsolete and unused equipment to reduce power

• Optimize cooling and facility infrastructure

• Consolidate and group applications by service level

• Virtualize / setup private clouds across sites

• Automate standard operating procedures

• Participate in ancillary services and demand response

The Impact of an Outage for Data Centers Today – Reactive:

•Tier 3/4 facility redundancy•Hot/Hot or Hot/Cold setup•Upon failure:

– Generator kicks in, offline from grid

– Shift to secondary data center

– Run double peak capacity 24x7

Tomorrow – Proactive:•Integration into Utility Services for preventive actions

– Leverage co-generation capabilities

– Integrate alternative energy sources

– Automated shift and shed across sites

– Tier applications by service level

– Application reliability over facility reliability

– Data centers get paid for upgrades by participation in energy markets
