mounted automatically. This file system is simple as each line must represent a file system
that should be mounted.
More complex storage management
Complex management paradigms are used when we want to achieve flexibility, more
performance, additional management structures or even redundancy .
What is raid
It means a redundant array of an independent disk. It allows someone to categorize drives and
later manage them as a single unit with more capabilities as it uses virtualization technology
and also it is storage management. The features of raid arrays always depend on the raid
level. The raid level, on the other hand, defines the relationship of the disk in the array. The
level will also impact the performance and the redundancy of the set.
Most common levels
❖
RAID 0 - This level indicates the drive splitting phase. By splitting it means that the data
is written on the array, then split and later distributed among the various disk in that particular
set. It has merit since it can be read or written. However, it faces drawbacks as failure to a
single drive can lead to loss of data from the entire array. This is due to the fact that no single
disk contains enough information about the content needed to rebuild.
❖
RAID 1 - Can be used in making a copy of some data. For example, you have 2 TB hard
drives; in total, you would have 4TB hard drives. In mirroring you will be able to see only the
2 TB or the logical hard drive. However, while saving data it will write on both drives. The
minimum number of dives must be more than two since in an event one of the drives fails,
you will get the data from the other disk; hence ensuring there is no data loss.
