RAID in Cloud Hosting
The hard disks which we use for storage with our top-notch cloud web hosting platform are not the standard HDDs, but quick solid-state drives (SSD). They operate in RAID-Z - a special setup intended for the ZFS file system that we employ. Any content that you add to your cloud hosting account will be stored on multiple hard drives and at least 1 will be used as a parity disk. This is a specific drive where a further bit is included to any content copied on it. If a disk in the RAID fails, it will be replaced without any service disruptions and the information will be rebuilt on the new drive by recalculating its bits thanks to the data on the parity disk plus that on the other disks. This is done to guarantee the integrity of the information and together with the real-time checksum authentication which the ZFS file system runs on all drives, you will never have to concern yourself with the loss of any information no matter what.
RAID in Semi-dedicated Hosting
The information uploaded to any semi-dedicated hosting account is saved on SSD drives which operate in RAID-Z. One of the drives in this kind of a setup is used for parity - each time data is cloned on it, an extra bit is added. If a disk happens to be flawed, it will be taken out of the RAID without interrupting the work of the websites because the data will load from the rest of the drives, and when a new drive is included, the info which will be copied on it will be a blend between the information on the parity disk and data saved on the other hard drives in the RAID. This is done so as to guarantee that the info that is being duplicated is accurate, so once the new drive is rebuilt, it could be incorporated into the RAID as a production one. This is one more guarantee for the integrity of your data because the ZFS file system that runs on our cloud web hosting platform analyzes a unique checksum of all of the copies of your files on the different drives in order to avoid any probability of silent data corruption.
RAID in VPS Web Hosting
In case you take advantage of one of our virtual private server plans, any content which you upload will be kept on SSD drives which operate in RAID. At least 1 drive is employed for parity to guarantee the integrity of the data. In simple terms, this is a special drive where info is copied with one bit added to it. If a disk within the RAID stops working, your sites will continue working and when a new disk substitutes the malfunctioning one, the bits of the data that will be copied on it are calculated by using the healthy and the parity drives. That way, any chance of corrupting data during the process is prevented. We also employ regular hard drives which operate in RAID for storing backup copies, so in case you add this service to your VPS plan, your content will be kept on multiple drives and you won't ever have to worry about its integrity even in the event of multiple drive failures.
