RAID in Cloud Hosting
The drives which we use for storage with our top-notch cloud Internet hosting platform are not the standard HDDs, but high-speed solid-state drives (SSD). They work in RAID-Z - a special setup developed for the ZFS file system that we employ. Any content that you upload to the cloud hosting account will be saved on multiple hard drives and at least one shall 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 stops functioning, it will be changed with no service disruptions and the info will be recovered 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 guarantee the integrity of the data and together with the real-time checksum authentication that the ZFS file system runs on all drives, you won't ever have to concern yourself with losing any data no matter what.
RAID in Semi-dedicated Servers
The SSD drives which are used for holding any website content uploaded to the semi-dedicated server accounts that we provide operate in RAID-Z. This is a specific configuration where one or more drives are used for parity i.e. the system will include an additional bit to any data cloned on this kind of a hard drive. In case that a disk fails and is replaced with a new one, what information will be copied on the latter shall be a combination calculated between the data on the other disks and that on the parity one. This is done to ensure that the data on the new drive shall be correct. During the process, the RAID will continue functioning adequately and the malfunctioning drive will not affect the adequate operation of your sites by any means. Using SSDs in RAID-Z is a fantastic addition to the ZFS file system which runs on our cutting-edge cloud platform in terms of preserving the integrity of your files as ZFS uses special digital identifiers identified as checksums in order to prevent silent data corruption.
RAID in VPS Servers
The SSD drives which we use on the physical machines where we generate VPS servers work in RAID to ensure that any content which you upload will be available and intact at all times. At least 1 drive is employed for parity - one bit of information is added to any data cloned on it. In the event that a main drive fails, it is replaced and the info that will be copied on it is calculated between the rest of the drives and the parity one. It's done this way to make sure that the needed info is copied and that no file is corrupted since the new drive will be included in the RAID afterwards. We also use hard drives operating in RAID on the backup servers, so in the event that you add this upgrade to your VPS plan, you'll use an even more reliable web hosting service as your content will be available on multiple drives irrespective of any unpredicted hardware malfunction.
