Explanation:

Key Characteristics of a Data Center
•Availability: A data center should ensure the availability of information when required.
Unavailability of information could cost millions of dollars per hour to businesses, such as financial
services, telecommunications, and e-commerce.
•Security: Data centers must establish policies, procedures, and core element integration to
prevent unauthorized access to information.
•Scalability: Business growth often requires deploying more servers, new applications, and
additional databases. Data center resources should scale based on requirements, without
interrupting business operations.
•Performance: All the elements of the data center should provide optimal performance based on
the required service levels.
•Data integrity: Data integrity refers to mechanisms, such as error correction codes or parity bits,

which ensure that data is stored and retrieved exactly as it was received.
•Capacity: Data center operations require adequate resources to store and process large amounts
of data, efficiently. When capacity requirements increase, the data center must provide additional
capacity without interrupting availability or with minimal disruption. Capacity may be managed by
reallocating the existing resources or by adding new resources.
•Manageability:
A data center should provide easy and integrated management of all its elements.
Manageability can be achieved through automation and reduction of human (manual) intervention
in common tasks.
