If you ever intend to manage large, corporate, enterprise wide solutions to data storage, then you will surely come across RAID arrays. RAID, which currently stands for redundant array of independent disks, formerly known as redundant array of inexpensive disks, saves data across multiple different hard drives making it quicker and safer for storage of important and sensitive data. The main reason for the use of RAID disks is to improve data integrity and performance. By saving data on multiple drives, you essentially improve the possibility of data recovery and make the process of data storage faster than if saved on one, single hard drive.
One of the most inventive points of a RAID system is that, to the operating system, the array of many different drives is seen as only one drive on the system. The unique methods of a RAID system also use a striping technique that is unusual to any other system. RAID systems stripe partitions among the different drives that are installed. The different partitions are addressed in order and data is layered over each drive numerically.
What does this do for a business? Well, for the individual user, RAID drives are impractical because of the cost associated with installation and maintenance. However, using RAID drives allow large amounts of data to be layered across the many different disks installed. This gives a huge performance boost to clients that save data across the network. Basically, the server is able to save a large piece of information like an image or video across many drives at the same time greatly decreasing the time it takes to save the data. Ultimately, this system decreases the time it takes to save data and improves performance across all organizations.
If you are an administrator looking to employ RAID systems in your LAN, then there are plenty of different systems to choose from which will become an issue when you finally deploy your chosen solution. RAID systems are layered, so each hard drive that is installed needs to have a large capacity that is able to handle the large amount of data that is striped across every layer of the partitioned drives.
RAID types are number from 0 to 7 and then skipping to 10. After 10, there are other numbered solutions, but the main ones that are implemented currently are the 0 through 7 solutions and found in existing network applications. As an administrator, you should know the several different solutions to make your viability as an information technology LAN expert improved. Knowing RAID systems are in demand since the technology being used is mainly in large corporations. Many people who implement these systems are in demand since the skills are uncommon among many information technology experts.
Whatever your methods of data storage, it's also imperative to have a secure, data recovery system in order to make sure the corporate data is safe. The loss of data in a corporation can cost the company millions of dollars, so securing data can save large resources and assets in the future.
