RAID in Cloud Hosting
The cutting-edge cloud hosting platform where all cloud hosting accounts are made employs fast NVMe drives as an alternative to the classic HDDs, and they operate in RAID-Z. With this setup, multiple hard disks function together and at least one is a dedicated parity disk. Simply put, when data is written on the rest of the drives, it is copied on the parity one adding an extra bit. This is done for redundancy as even if a drive fails or falls out of the RAID for some reason, the data can be rebuilt and verified thanks to the parity disk and the data recorded on the other ones, thus practically nothing will be lost and there will not be any service disorders. This is one more level of protection for your information together with the revolutionary ZFS file system that uses checksums to guarantee that all the data on our servers is intact and is not silently corrupted.
RAID in Semi-dedicated Hosting
The RAID type which we employ for the cloud Internet hosting platform where your semi-dedicated hosting account shall be created is called RAID-Z. What's different about it is that at least 1 of the disks is employed as a parity drive. Simply put, whenever any kind of data is duplicated on this particular drive, one more bit is included to it and in the event that a defective disk is changed, the info which will be cloned on it is a mix of the data on the other drives in the RAID and that on the parity one. We do this to guarantee that your information is intact. During this process, your websites will be functioning normally because RAID-Z allows for an entire drive to fail without service disruptions and it simply works by using one of the other ones as the main production drive. Using RAID-Z together with the ZFS file system which uses checksums to ensure that no data will get silently corrupted on our servers, you will not need to worry about the integrity of your files.
RAID in VPS Hosting
The NVMe drives that we use on the machines where we set up virtual private servers function in RAID to ensure that any content which you upload will be available and intact all of the time. At least a single drive is employed for parity - one bit of information is added to any data cloned on it. If a main drive breaks down, it is replaced and the data that will be cloned on it is calculated between the rest of the drives and the parity one. It's done this way to ensure that the correct info is copied and that no file is corrupted because the new drive will be incorporated into the RAID afterwards. We also use hard disk drives operating in RAID on the backup servers, so in the event that you add this upgrade to your VPS plan, you will use an even more reliable Internet hosting service because your content will be available on multiple drives regardless of any sort of unpredicted hardware malfunction.
