Nowadays, both businesses and individuals start to use RAID systems so as to gain improved performance. Although RAID system does provide users with many benefits, it can fail due to its vulnerable components. This article will list out 4 top types of RAID system failures.
RAID refers to redundant array of independent disks. It’s a kind of data storage technology, which can combine multiple physical hard drives into a single logical unit. Through it, not only will users gain device’s improved performances, but also users can achieve additional storage space simply by inserting an extra drive. Moreover, majority of RAID arrays are fault-tolerant, which is one of its top advantages.
Even though RAID boasts of multiple merits, it still can be subject to failures as it consists of vulnerable hardware and software components. Once a RAID system fails, data stored in it will tend to get compromised as well, such as damaged PST. In order to better avert RAID system failures, you’d better figure out the types of RAID failures. So, thereinafter, we’ll expose the 4 primary kinds of potential RAID failures.
1. Hardware Failures
First off, as mentioned above, RAID server is made of mechanical and electronic components. They are subject to wear and physical damage. Therefore, if any one fails in the RAID, the server will encounter hardware failures, including hard disk component failure, RAID controller failure, power supply failure, overheating and so on.
2. Software Failures
Without any doubts, RAID system is set up and configured on software level. It’ll meet up with a variety of logical issues. Hence, RAID system could experience software failures, say damaged files or folders, RAID configuration faults, registry file corruption, backup failures as well as virus infection and malware attacks.
3. Application Failures
So-called application failures are similar to software failures to some extent. Such a kind of failures commonly involves the applications and programs installed in the RAID server. More specifically, you are unable to access the applications in a normal fashion, like unable to run apps or load files, corrupted app files, locked databases for app access.
4. Failures from Human Error
Furthermore, in some degrees, human errors are inevitable. Therefore, RAID can fail due to human errors. For instance, you accidentally delete important files or records, mistakenly reformat the partitions, drives and even the entire arrays, or overwrite the databases, set up RAID incorrectly or lose the passwords, thereby incapable of accessing the RAID environment properly.
