IP from that network.

8. How to
replace a failed RAID controller ?
a. This
depends on the type of controller used. If you are using modern RAID
controllers and are trying to replace with the same model, then the RAID should
work without any issues as the RAID configuration or metadata is stored in the
disk array. But you should ensure that you are using the same model from vendor
or a model which is compatible with the failed controller.
9. What is
the difference between RAID 1 and RAID 5 ?
a. RAID 1 -
Mirroring - This RAID configuration gives you maximum redundancy as the same
data is written into two disks at a time. But this solution will be costly as
you always need to have disks double of what you actually require. Minimum 2
disks required.
b. RAID 5 -
This RAID is the most popular RAID configuration. This works on the parity
principle. Minimum 3 disks required. Even if one disk fail, the data of the
failed disk can be calculated from the parity stored in the other 2 disks.
10. In RAID
5, which activity is faster - Read or Write ?
a. Good Read
performance but slower Write operations due to parity calculation.
b. RAID 0
and RAID 1 has got excellent Read and Write performance
