Now a days data center plays the most crucial and vital role irrespective
to business segment. The cost of
data center downtime has increased significantly for companies in the last
three years, according to results of a recent study by Ponemon Institute
published on February 1, 2011, sponsored by Emerson Network Power. Read the study report: "Cost of
Data Center Outages: Sponsored by Emerson Network Power"
Research indicates "data center outages have serious
financial consequences for an organization. According to the study, the cost of
a data center outage ranges from a minimum cost of $38,969 to a maximum of
$1,017,746 per organization, with an overall average cost of $505,502 per
incident."
Actual cost of downtime in these days would be much more than the above
calculation. Could you ever imagine if Amazon went down for a minute just
before eve of Christmas or New Year or Alibaba had an interruption for a minute
before Chinese New Year? I am sure that you need a large scientific calculator
to compute this.
According to the above study report, 37% of the unplanned outages
occurred related to site or location. Thus data center site selection is one of
the major decision that a management should take. There are several criterion
for selecting site for your future business. Depending your choice, your
business might be bloomed or doomed.
Selection criteria can be divided into below broad categories:
- Potential Natural
Hazardous Area
- Potential Man-made
Hazardous Area
- Proximity Evaluation
- Building Evaluation
For selecting
a site, Potential Natural Hazardous Area should be avoided for below reasons:
• Lightning
• Flooding
• Typhoon
• Forest Fires
• Seismic Prone Area
Sometimes Man-made Hazardous Area also impacts data center overall
performance, thus should be avoided.
• Flight path
• Tunnels, lakes
• Train/airport
• RF towers
• Power distribution network
• Industrial pollution
Proximity Evaluation is one of the premier selection norm for
selecting site.
• Emergency Services e.g. Fire, Police, Medical
Facilities
• neighborhood
• Public transport and public roads
• High risk targets e.g. Embassies, Govt.
Building, Power Stations, Radio/TV Station
And lastly Building
Evaluation is required for below reason:
• Rent/Buy/Build
• History of the building and/or area (flood,
fire etc.)
• National building code
• 24x7 access
• Level/floor within the building
• Space required/ potential expansion
• Floor loading capacity
• Slab to slab height (min. 3.8meter)
• Power Capabilities: Redundancy & Capacity
• Network Capabilities: Redundancy &
Diversity
• External Supply Capabilities
• Utility duct
• Secured perimeter
• Grounding space
• Standby generator, external generator
provision
• Delivery of heavy/big equipment's and route
to data center
Don't forget your prime selection criteria which is your Budget, Budget, & Budget!!
