This case study shows the work which was made by me Atdhe Buja during the last project study

in Master Computer Science and Engineering degree, before i choose Master Thesis. This pilot

project helps me to choose the right master thesis for this i want to thank my professor PhD.

Petrit Shala for everything supports me on this project, professional advice. This project was a

very good experience for about 3 months.

The first thing on this project is hardware infrastructure main components of the Data Center are

environmental controls, data communications connections, redundant power supplies and

security devices.

Servers

Servers deployed in the data center today are either full featured and equipped rack-mount

servers or blade servers.

Storage

Storage requirements vary by server type. Application servers require much less storage than

database servers. There are several storage options: DAS, NAS, SAN.

Connectivity

The networking component provides connectivity to the data center, for example L2/L3 switches

and WAN routers. As stated earlier, motivated by server virtualization, data center connectivity

design is moving to network virtualization.

High Availability Requirements

High Availability (HA) is crucial to data center networks. Data center failure costs include both

revenue lost and business creditability. System availability is simply calculated by “system

uptime” divided by “total time.”

Environmental Considerations

Several environmental considerations exist within the TIA-942/ANSI telecommunications

infrastructure data center standard that are similar to the equipment room requirements set forth

in previous TIA standards.

The following list are presented technical, that i had to have to achieve first objective hardware

infrastructure.

Needs for this Test Environment:

HP Rack 42U

Network Switch

Network Cable

UPS system

KVM Monitor

Servers

4 (four) servers and 1 (one) Storage, are configured following services with:

o SharePoint 2010

o SQL Server 2012

o Windows Hyper-V

o Citrix services

Data Center Networking – Connectivity and Topology Design

Data Center Network Design Goals

Performance

Scalability and agility

Flexibility to support various services

Security

Redundancy/High availability

Manageability

Lower OPEX and CAPEX

Long term availability

Figure 3 Two-tier Data Center Design

The design above shows virtual switches used at the data center LAN access layer providing

connectivity for both applications and IP storage – iSCSI or NFS attached.

Conclusion

Each of the components of the data center and its supporting systems must be planned, designed,

and implemented to work together to ensure reliable access of data center resources while

supporting future requirements. Neglecting any aspect of the design can render the data center

intolerable availability.
