RAID in Website Hosting
The disk drives that we use for storage with our outstanding cloud Internet hosting platform are not the classic HDDs, but high-speed NVMes. They operate in RAID-Z - a special setup developed for the ZFS file system which we employ. All the content that you upload to the website hosting account will be held on multiple drives and at least one will be used as a parity disk. This is a specific drive where a further bit is added to any content copied on it. In case a disk in the RAID fails, it'll be replaced without service disturbances and the info will be rebuilt on the new drive by recalculating its bits using the data on the parity disk along with that on the remaining disks. This is done to ensure the integrity of the data and together with the real-time checksum validation that the ZFS file system performs on all drives, you won't ever have to worry about losing any info no matter what.
RAID in Semi-dedicated Hosting
The RAID type which we employ for the cloud hosting platform where your semi-dedicated hosting account will be created is named RAID-Z. What is different about it is that at least 1 of the disks is used as a parity drive. In simple terms, whenever any kind of data is duplicated on this particular hard drive, one more bit is added to it and if a malfunctioning disk is replaced, the data which will be copied on it is a combination of the data on the remaining drives in the RAID and that on the parity one. We do this to make sure that your information is intact. During this process, your Internet sites will be working normally since RAID-Z allows for a whole drive to fail without service disturbances and it simply works by using one of the other ones as the main production drive. Employing RAID-Z together with the ZFS file system which uses checksums to ensure that no data shall get silently corrupted on our servers, you will never have to worry about the integrity of your files.
RAID in VPS Hosting
The physical servers where we make virtual private server employ fast NVMe drives that will boost the speed of your Internet sites significantly. The hard disks work in RAID to ensure that you won't lose any info because of a power loss or a hardware breakdown. The production servers use multiple drives where the info is saved and one disk is used for parity i.e. one bit is added to all the information copied on it, which makes it much easier to recover the website content without loss in case a main drive stops working. If you pick our backup service, your info will be stored on an individual machine that uses standard hard-disk drives and even though there is no parity one in this case, they are also in a RAID to make sure that we will have a backup copy of your site content all of the time. With this setup your data will always be safe because it will be available on a lot of drives.
