Question
You recently got hired as a Network Coordinator. You have been assigned to work under the Network Administrator of a network which has 5 Windows Servers 2012 EE and 200 Windows 7 workstations. Recently the demand on the storage has grown in the network and you have been asked to increase the storage for the network. Your supervisor wants you to find the pros and cons of using SAN or NAS. What considerations will you follow to choose one over the other? How do these technologies compare with cloud computing? If you were to design the storage needs for a medium sized company without any restrictions and considerations, which technology would you recommend and why?
Explanation / Answer
Answer:
Pros & Cons of Network Attached Storage
Pros
Cons
It acts as a complete and standard platform to the administrators for storing the files and documents.
It helps to fasten the work by storing huge amount of data within a short span of time.
It helps for easy and fast communication between other electronic devices like computers, printers, scanners, etc. and thus reduces both the time and the extra workload of the individual.
As the network attached storage server device holds a large capacity of files within it, it helps in preventing the unwanted and unexpected errors like missing files, file corruption, etc. and thereby leads to a healthy outcome of the work in the company.
The major drawback of using the network attached storage device is that it mainly runs on the file system Linux. During a power loss or machine failure, to retrieve or to recover any document or file from the system you are in need of help of the professional data recovery software and services.
The end users who want to back up the data cannot proceed directly. They have to do it through the installed operating system only.
Consideration to choose NAS:
i) NAS is shareable
ii) NAS is scalable
iii) It has the hight performance
iv) It provide remote replication and snapshots
Consideration to choose SAN(Storage Area Network):
i) It is sharable
ii) SAN is highly scalable in capacity and performance
iii) It provides synchronous replication
iv) Highly resilient
Compared with Cloud Computing:
NAS is generally used for file-level computer data storage but NAS provides both storage and a file system. In fact, NAS is useful for more than just general centralized storage provided to client computers in environments with large amounts of data. By providing storage services, NAS can enable simpler and lower cost systems such as load-balancing and fault-tolerant email and web server systems.
SAN is a dedicated network that provides access to consolidated, block level data storage. Common uses of a SAN include databases, server clustering, messaging applications (e.g. Microsoft Exchange), and high I/O, transaction-intensive apps
Conclusion:
I strongly recommend the SAN, it is so modern technology over NAS. And cloud storage is better than these two SAN and NAS
