1. ABC Company was facing downtime issues and lacked flexibility and scalability to respond to growth in customer base and demands. They consulted a network storage infrastructure provider to address these problems. 2. Implementing a scalable storage network provided benefits like end-to-end redundancy, limitless scalability, 24/7 reliability and speed to attract and retain customers. It also lowered ABC's total cost of ownership. 3. Computer networks can be arranged using different topologies like bus, star, ring and mesh. Each topology works differently in how devices are connected and how messages are passed through the network.

5 ABC company is an internet service provider. The main goal of ABC is to provide 24
X7X365 storage capacity, storage management and internet service to the customers. It
now needs a solution that will eliminate downtime. Downtime is nothing but the time
during which a computer or computer system is down, or inoperative due to hardware or
software failure. We also need the flexibility in quick response to both the development in
customer base and additional capacity and service demands of the customers.
ABC company took the help of network storage infrastructure software provider to achieve
their goals by providing support for end to end redundancy and bondless scalability.
By creating a scalable storage network with the ability to confidentially deliver the
24X7X365 reliability, and speed that outsourcing customers demand, it has enabled the
ISP/SSP to attract and retain customers and substantially build its business. As the same
time, the solution has effectively lowered ABC company’s total cost of ownership for its
entire storage solution: the IP Stor/CNP union has enabled a painless, flexible cost
effective, scalable solution. The complementary IP Stor/CNT solution has allowed to its
customers easily and cost- effectively.
