Redundant array of independent disks (RAID) is a popular data storage technology that is chosen by both individuals and companies. Thus here we will provide 6 tricks for you to set up RAID ideally.
Redundant array of independent disks (RAID) is a widely used data storage technology. It has many levels that can meet different demand like improvement in reliability, capacity or availability, and etc. However, setting up RAID correctly is not that easy. It is influenced by many factors. Here are 6 vital tricks that can help you.
Hard drive in the RAID is the most basic factor. You should select typical drives that are ideal for your RAID setup. Thus you should do researches in order to have a clear understanding about RAID controllers and hard drives you want to choose. All in all, you can pick out hard drives that meet following situations.
- Drives should have same formatted capacities.
- They should have same spindle speed and transfer speed.
- They are deal for your RAID controllers.
Since RAID has many levels and each level have its own characters. According to your personal needs on the data storage performance, you can select a specific level. Now, ask yourself following question and then make a decision: Which is important for you, redundancy, performance, capacity, or a combination?
Like RAID requires various drives, multiple drives have different requires towards power. You should have a good awareness of the power consumption. If not, when drives don’t have enough power to work normally, drives or RAID controllers will get corrupt easily. Besides, these issues might be misdiagnosed as software, or cable problem. Then you might spend more time on finding out the real reason.
Cooling is a factor which is easy to miss. When you have many spinning drives in your RAID and they are equipped with low end computers. Then a cooling problem is prone to occur. And overheat will also have great impact on the lifespan of the drives. Therefore, you ought to take this factor into account.
5.(Uninterruptable power supply) UPS
It’s believed that many don’t have uninterruptable power supply (UPS). Although many people may have not been affected yet, but when it comes to RAID, things get more complicated. Many RAID stores data in cache to improve write performance. But data in cache will disappear when meeting power failure. So it’s important for you to get UPS for your RAID.
Many people take RAID as their data backups directly. This is a common misconception. If you meet Outlook damage and the RAID gets corrupt too, then you will fail to fix your data from RAID. Thus, extra data backups are badly in need because RAID cannot replace backups and easy to corrupt.
