Hope you already have a good idea about the raid. First of all you need to know if your server needs raid data. Usually the rear position will depend on how important the uptime is for a person’s operation. The logical unit that improves performance by distributing multiple drives using an error start screen is called a raid array. 

Individual server and business downtime is lost when raid is not installed when the drive is reconfigured and replaced. When raid is installed, the drive is replaced. In this case you can rebuild and sync raid from old drive to new drive without any backup restore. Those who have more or less the idea about raid may know that raid is of two types, one is hardware and the other is software. Many of you may be looking for the advantages and disadvantages of raid hardware and software and want to know more about them. In today’s discussion I will discuss in some detail about these two types of raids.

First of all we will talk about hardware raids. The drives are linked to a RAID controller card installed onto the server’s motherboard in a hardware RAID configuration. This may provide optimal performance because the processing server is powered by a raid card instead. This provides less stress when the backup is written and the data is restored.

So far we have learned a brief explanation about the hardware raid. Now we will explain in some detail about the software raid. The setup is controlled by the operating system software if the disks are attached to the server motherboard without a RAID controller. This is a cheaper option than other options. First you need to connect the drives and configure the OS. You’re limited to the RAID layers that your operating system can handle. Hardware RAID provides more versatility than software RAID by allowing for more configuration options and removing the limitations of software RAID. If you use software RAID, performance may be an issue depending on how complicated your RAID arrangement is.

There are different types of Raid confectionery but all these Raid confectionery vary in redundancy, speed and disk size. But you know which raid configuration is the best?

RAID 0, RAID 1, RAID 5, and RAID 10 are some of the most frequent RAID levels. Here’s a quick TLDR chart that shows the benefits and drawbacks of each option. Always be careful about losing raid data because raid data recovery is a complicated process.

Many people believe that a BBU (Battery Backup Unit) should be connected to the RAID controller since it protects and maintains the data cached on the RAID card of your server. A physical lithium ion battery is usually used. Before the updates leave the cache and commit to disk, your bare metal server loses power, causing data loss. You won’t be able to recover the data of the RAID card, and you won’t know which files were corrupted. In essence, a BBU is a data backup unit.
