Which of the following best describe the infrastructural needs of the rack equipment? (Choose all that apply)
A.
Cost-effectiveness
B.
Scalability
C.
Networkability
D.
Space optimization
Explanation:
Rack equipment must be selected and installed on the following basis:
1. Scalability: Because server installations expand in size over time, rack installations
should be modular and planned in such a way as to readily accommodate future data center growth.
2. Flexibility: Budget constraints should not serve as a hindrance when the client selects
a rack solution. Both standard and enterprise rack offerings should permit mixing and matching of EIA-compatible equipment.
3. Availability and Reliability: Power distribution units (PDUs) should be selected that
enable connectivity to redundant, diverse power sources, including UPS options.
4. Manageability: Clients appreciate the ability to control all of their racked systems
from a single console, using appropriate management software. This type of software often comes with rack configuration tools that help plan and validate a given installation.
5. Rapid implementation: Well-designed rack systems can be pre-installed prior to
shipment following the submission of a validated installation plan. The rack arrives at the data center fully equipped and ready to run.
6. Security: Well-designed racks are manufactured with lockable doors to provide a
more secure environment for the protection of hardware, media, and data.
7. Space optimization: Clients want easy access to crucial components in addition to the
flexibility of consolidating server space when possible.
8. Cost-effectiveness: Rack solutions must be competitively priced, deliver operational
cost savings, simplify management, provide ease of configuration, offer simplified cabling, and consume no unnecessary office real estate.
