RAID in Cloud Hosting
The disk drives that we employ for storage with our ground-breaking cloud web hosting platform are not the traditional HDDs, but extremely fast solid-state drives (SSD). They function in RAID-Z - a special setup developed for the ZFS file system that we employ. All of the content that you upload to the cloud hosting account will be kept on multiple hard disks and at least one shall be employed as a parity disk. This is a specific drive where an additional bit is added to any content copied on it. If a disk in the RAID stops functioning, it'll be changed with no service interruptions and the data will be recovered on the new drive by recalculating its bits thanks to the data on the parity disk along with that on the other disks. This is done in order to guarantee the integrity of the info and along with the real-time checksum verification that the ZFS file system executes on all drives, you won't ever have to concern yourself with the loss of any info no matter what.
RAID in Semi-dedicated Servers
The info uploaded to any semi-dedicated server account is saved on SSD drives which function in RAID-Z. One of the drives in such a configuration is used for parity - any time data is cloned on it, an additional bit is added. If a disk happens to be defective, it will be taken out of the RAID without interrupting the operation of the sites as the data will load from the other drives, and when a brand new drive is added, the data which will be duplicated on it will be a combination between the data on the parity disk and data stored on the other hard drives in the RAID. This is done so as to ensure that the information which is being cloned is correct, so once the new drive is rebuilt, it can be integrated into the RAID as a production one. This is one more guarantee for the integrity of your information because the ZFS file system that runs on our cloud hosting platform analyzes a unique checksum of all of the copies of the files on the various drives to avoid any chance of silent data corruption.
RAID in VPS Servers
In case you employ one of our VPS server plans, any content which you upload will be stored on SSD drives which function in RAID. At least 1 drive is intended for parity to guarantee the integrity of your data. In simple terms, this is a special drive where information is copied with one bit added to it. If a disk from the RAID breaks down, your websites will continue working and when a new disk takes the place of the defective one, the bits of the information that will be duplicated on it are calculated using the healthy and the parity drives. That way, any chance of corrupting data during the process is averted. We also use regular hard drives which function in RAID for storing backup copies, so should you include this service to your VPS plan, your content will be saved on multiple drives and you will never have to worry about its integrity even in the event of multiple drive failures.
