Question

You are the server administrator at your company. A new server has arrived and your boss has asked you to setup the server. After inspection you notice the server has two NICs, 16 GB of RAM, 2 - 100 GB hard disks, and 3 - 200 GB hard disks. Your boss asks you to configure a storage solution that meets the following requirements:

The operating system storage solution must be fault tolerant. Disk performance is not a priority for the operating system storage. The data storage needs to be separate from the operating system storage. It must be on a storage solution that provides high performance, and must provide redundancy for continued business in case of a drive failure.

How would you address the operating system storage? The data storage?

Explanation / Answer

USE RAID, as RAID (redundant array of independent disks; originally redundant array of inexpensive disks) is a way of storing the same data in different places (thus, redundantly) on multiple hard disks. By placing data on multiple disks, I/O (input/output) operations can overlap in a balanced way, improving performance. Since multiple disks increases the mean time between failures (MTBF), storing data redundantly also increases fault tolerance.
