EE4217 Assignment 1 (Total 30%)

hi anyone, i really need the solution of all the question. It can save my life. Thank you

 

 
EE4217 Assignment 1 (Total 30%)
1. SAN Case Study (15%)
A mid-sized publishing house has a centralized IT department located in San Francisco,
CA, connected to 3 branch offices on the west coast. Recent analysis of the storage
environment suggests that they are getting poor ROI in their storage infrastructure. The
company’s current infrastructure consists of several storage arrays direct-attached to a
heterogeneous mix of 90 servers. All servers are dual-attached to the arrays for reliability
and redundancy.
Since each storage device has 32 connectivity ports, each could support a maximum of 16
servers. The company sees the 32-ports as a limitation. Each storage device has the disk
capacity to support more than 16 servers. However, there was no way to add a 17th
server to make use of that capacity and support future growth.
Proposal:
How would you suggest that the company restructure their environment?
[10 marks]
List the advantages and disadvantages of your proposed solution. (Note: You will need to
justify your choice based on scalability, performance, and availability of the new
solution.)
[5 marks] 2. Remote Replication Case Study (15%)
A Manufacturing Corporation maintains the storage of their mission critical applications
on high-end Storage Arrays on RAID 1 volumes. The corporation has two data centers
which are 50 miles apart. The corporation’s mission critical Database application takes
up 1 TB of storage on a high end Storage Array. In the past year, top management has
become extremely concerned because they do not have DR plans which will allow for
zero RPO recovery if there is a site failure. The primary DR Site is the 2nd Data Center 50
miles away.
The company would like explore remote replication scenarios which will allow for near
zero RPO and a minimal RTO. The company is aware of the large costs associated with
network bandwidth and would like explore other remote replication technologies in
addition to the zero RPO solution.
Proposal:
Propose a remote replication solution to address the company’s concern. [5 marks]
Justify how your solution will ensure that the Company’s needs are met. [10 marks]
