Transcript of Data Center Networking

Presentation by Feliks Lesar Data Center Networking Techical overview of Data Centre Networking
Background and related areas
The significance of Data Centre Networking to present and future networked applications
Important issues: benefits, drawbacks, disadvantages, remaining problems/limitations
Relationship of Data Centre Networking to the course BN208-Networked Applications Outline Of The Presentation The idea of Data Centre Networking is derived from the idea of facilitating the computer systems and its different components with storage systems with its telecommunications.

Generally, it includes redundant data communications links, backup power sources and supplies, security devices scheme like locks and environmental controls like the fire suppression and air condition.

Nowadays, almost all successful companies have implemented their own Data Centres to maintain their records and business operations as efficiently and effectively as they possibly can. Technical Overview of Data Centre Networking Background And Related Areas As mentioned, the Data Center Networking is the core of the business operations in terms of technology such as accessing work email, accessing the work server for data on customer, sales figures, accounting journals, business transactions and more.

To put it simply it holds the operations of the company business together so it is crucial to implement a proper structure and planning for these data centres. Significance Of Data Center Networking To Present And Future Networked Applications PRESENT FUTURE On the other hand, the future time will only enhance a better understanding of the more improved technologies and an even faster data processing and more data storage with a hint of green data center in mind.

Although the idea of creating green data center had emerged the full extent of the action had not been seen. However more and more companies had been looking into the option to opt in for the idea of saving the planet’s resource and actively looking for ways to send out the positive image to the society and IT users to reduce the impacts of having these data centers to the environment. Benefits Important Issues Drawbacks Advantages Disadvantages Remaining problems/ limitations Networked applications depends on the availability and reliability of the data centre networking.
Networked applications uses the data centres to process data or perform work.
Both networked applications and data centre networking work hand in hand to sustain operations of any organisation.
Please have a look at the above network architecture diagram (similar to the one we have on week 4 lecture about the three tier architecture). Relationship To The Networked Applications References Thank You For Listening =) Faster data processing speed
Data storage
Data redundancy
Reliable
Secure data with off-site data centre location
Autonomate system processes
Data security Expensive to run (Electricity[power and cooling], security, replacement of faulty parts, etc)
Required trained personnel to manage
Social and impacts to the environment can be negative
Expensive to replace/upgrade.
Data center space cost. Support cloud computing and virtualization.
Increase in data storage
Disaster recovery in times of natural disasters, fire and other unfortunate events.
Support other services like VoIP, server farms, enterprise applications, VPN, backups and more.
Can be upgraded as the business requires.
Reliable in terms of data availability.
Can manage multiple data processing like enterprise applications, emails, VoIP and other services running at the same time. Has to be managed properly.
Downtimes will occur during first implementation.
Expensive to maintain.
Can be disastrous if the primary and backup data centers are out of action.
Upgrades will need to be considered (This can be a double-edge sword for the company).
Will need to invest in staff training and retraining costs to keep up with the technologies Impacts to the environment can proven to be severe (the greening of Data enter)
In a real world scenario, everything has its life time just like data center equipments.
Primary and backup data center will need to be maintained and managed properly to minimise downtime and hence profit loss.
Technologies keep changing, companies will need to be smart in their decision-making to maintain their profits while improving the business operations when considering upgrades
Will always require trained personnels to maintain and manage the data centers. Work Experience with Cisco Systems and TAFE diploma in Networking. (2012).

The boom of microcomputers - smaller computer and server sizes contributes to more equipments being available in each of the Data Center location.
The boom of the dot com era - more and more Data Centers are required to be built to sustain the growth of the online society and the digital revolution.
The core of the business is the Data Center - data storage, redundancy, reliability and availability. More of these business objectives will be explained in the next few slides.
The rise of the Cloud Computing - the idea of virtualization demands more data processing and data storage like ever before, hence more Data Centers required to be built to satisfies the goal. In the present time, the Data Center Networking is definitely a vital part of the company’s system and its reliability of business operations depends on how the Network can manage during its peak hours of operations. Other significant factor would include the handling and running the business applications to accommodate the core business requirements and operational data within the business organization.

Some of the business application systems maybe proprietary and developed by the company internally, or purchased from vendors that sell the enterprise software such as the common business applications like the CRM and ERP systems like SAP, ORACLE for their database and data processing. Data Center Networking can often be used to provide for offsite backups. Backup tapes are often used; this can be taken of servers locally onto tapes.

Some of the backups can be sent through a secure channel over the internet to another data center to be stored securely. These backup data done this way to avoid the security threat as supposed if it was stored in the company’s location. Data Center Networking technology can also be deployed for disaster recovery. More and more companies pursue this path for data redundancy in an event when a disaster like fire, flood, or any other natural cause disaster occurred.

Big companies like Cisco Systems, IBM, Sun microsystems, Google, HP, Dell just to name some, have developed mobile solutions that can be installed and made operational in short period of time. Here is a data center network overview diagram...
