RAID in Cloud Hosting
The hard drives that we use for storage with our state-of-the-art cloud hosting platform are not the traditional HDDs, but super fast solid-state drives (SSD). They operate in RAID-Z - a special setup intended for the ZFS file system which we work with. All of the content that you upload to the cloud hosting account will be stored on multiple hard drives and at least one of them 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 stops working, it'll be replaced with no 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 guarantee the integrity of the information and together with the real-time checksum validation which the ZFS file system executes on all drives, you will never need to concern yourself with losing any information no matter what.
RAID in Semi-dedicated Hosting
The info uploaded to any semi-dedicated hosting account is stored on SSD drives that work in RAID-Z. One of the drives in this kind of a configuration is used for parity - any time data is copied on it, an additional bit is added. If a disk turns out to be faulty, it will be removed from the RAID without disturbing the operation of the websites because the data will load from the other drives, and when a brand new drive is included, the information which will be duplicated on it will be a blend between the data on the parity disk and data saved on the other hard drives in the RAID. That is done in order to ensure that the info which is being duplicated is accurate, so as soon as the new drive is rebuilt, it can be integrated into the RAID as a production one. This is an additional warranty for the integrity of your data as the ZFS file system which runs on our cloud Internet hosting platform analyzes a special checksum of all the copies of the files on the various drives to avoid any possibility of silent data corruption.
RAID in VPS
In case you employ one of our virtual private server packages, any content which you upload will be stored on SSD drives that function in RAID. At least 1 drive is used for parity to guarantee the integrity of the info. In simple terms, this is a special drive where info is copied with one bit added to it. In case a disk in the RAID fails, your websites will continue working and when a new disk takes the place of the defective one, the bits of the data that will be copied on it are calculated using the healthy and the parity drives. That way, any potential for corrupting data throughout the process is averted. We also use standard hard disk drives which function in RAID for storing backups, so if you add this service to your VPS plan, your content will be kept on multiple drives and you will never need to worry about its integrity even in the event of multiple drive breakdowns.
