Chapter Review Questions

     
1:

Your have an application that performs a significant number of random IO throughout the database. Why would a RAID 0 volume not necessarily improve the IO performance of the application?

2:

Give at least one reason why RAID solutions where parity data is stored on a single disk are not commonly used currently.

3:

Calculate the parity data, using an XOR truth table, for the following six disk + one parity disk RAID volume.

4:

RAID 3 and RAID 4 both utilize a single parity disk. When data in the RAID volume is being modified, it can be seen that RAID 3 offers poorer performance than RAID 4. Explain why this is so.
