RAID, or Redundant Array of Independent Disks, is a technology for saving data on a number hard drives that function together as a single logical unit. The drives can be physical or logical i.e. in the second case a single drive is split into different ones using virtualization software. Either way, the very same info is stored on all drives and the key benefit of employing this type of a setup is that if a drive breaks down, the data shall still be available on the other ones. Having a RAID also enhances the overall performance because the input and output operations will be spread among a couple of drives. There are several types of RAID based on how many hard drives are used, whether writing is done on all the drives in real time or just on a single one, and how the data is synced between the drives - whether it's recorded in blocks on one drive after another or it is mirrored from one on the others. All these factors indicate that the error tolerance and the performance between the different RAID types can vary.

RAID in Cloud Website Hosting

Any content which you upload to your new cloud website hosting account will be stored on quick SSD drives which operate in RAID-Z. This setup is built to work with the ZFS file system that runs on our cloud Internet hosting platform and it adds an additional level of protection for your content on top of the real-time checksum verification which ZFS uses to guarantee the integrity of the data. With RAID-Z, the data is saved on a couple of disks and at least one of them is a parity disk - whenever data is written on it, an additional bit is added, so in case any drive stops working for some reason, the stability of the info can be verified by recalculating its bits based on what is kept on the production disks and on the parity one. With RAID-Z, the functioning of our system will not be interrupted and it will continue functioning flawlessly until the problematic drive is changed and the information is synced on it.

RAID in Semi-dedicated Hosting

The RAID type which we use for the cloud hosting platform where your semi-dedicated hosting account shall be created is named RAID-Z. What is different about it is that at least one of the disks is employed as a parity drive. Put simply, whenever any data is duplicated on this specific disk drive, one more bit is added to it and in case a faulty disk is replaced, the data that will be cloned on it is a mix of the data on the remaining hard drives in the RAID and that on the parity one. This is done to make sure that your data is intact. During this process, your Internet sites will be functioning normally because RAID-Z allows for an entire drive to fail without causing any service interruptions and it simply uses one of the remaining ones as the main production drive. Employing RAID-Z together with the ZFS file system that uses checksums to guarantee that no data will get silently corrupted on our servers, you won't ever need to worry about the integrity of your files.

RAID in VPS Hosting

The physical servers where we make virtual private server use extremely fast SSD drives which will raise the speed of your websites substantially. The hard drives function in RAID to guarantee that you won't lose any data due to a power loss or a hardware failure. The production servers use multiple drives where the data is kept and one disk is used for parity i.e. one bit is added to all data copied on it, which makes it much easier to recover the content without any loss in the event a main drive stops working. If you pick our backup service, your info will be saved on an individual machine which uses standard hard-disk drives and even though there is no parity one in this case, they are also in a RAID to ensure that we will have a backup of your content all of the time. With this configuration your info will always be safe since it will be available on multiple disk drives.
