RAID in Hosting
The drives which we use for storage with our state-of-the-art cloud hosting platform are not the classic HDDs, but extremely fast solid-state drives (SSD). They operate in RAID-Z - a special setup developed for the ZFS file system that we use. All of the content that you upload to the hosting account will be held on multiple drives and at least one of them will be employed as a parity disk. This is a special drive where a further bit is added to any content copied on it. If a disk in the RAID stops working, it'll be replaced without any service disruptions and the information will be recovered on the new drive by recalculating its bits thanks to 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 validation that the ZFS file system runs on all drives, you'll never have to be concerned about the loss of any data no matter what.
RAID in Semi-dedicated Hosting
The SSD drives that are used for keeping any site content uploaded to the semi-dedicated hosting accounts that we provide function in RAID-Z. This is a special setup where one or more disk drives are employed for parity i.e. the system will include an extra bit to any data copied on such a disk drive. In the event that a disk fails and is replaced with another one, what info will be cloned on the latter shall be a mix calculated between the data on the remaining drives and that on the parity one. This is done to ensure that the data on the new drive shall be accurate. During the procedure, the RAID will continue operating normally and the faulty drive won't have an effect on the normal operation of your Internet sites in any way. Using SSDs in RAID-Z is an excellent addition to the ZFS file system which runs on our cutting-edge cloud platform in terms of preserving the integrity of your files because ZFS uses unique digital identifiers known as checksums so as to prevent silent data corruption.
RAID in VPS Hosting
If you use one of our virtual private server solutions, any content that you upload will be kept on SSD drives which operate in RAID. At least 1 drive is employed for parity so as to ensure the integrity of the information. In simple terms, this is a special drive where data is copied with one bit added to it. In case a disk within the RAID stops working, your Internet sites will continue working and when a new disk substitutes the defective one, the bits of the info that will be cloned on it are calculated by using the healthy and the parity drives. This way, any potential for corrupting data throughout the process is prevented. We also employ conventional hard disk drives that operate in RAID for storing backup copies, so in case you include this service to your VPS plan, your site content will be saved on multiple drives and you'll never need to worry about its integrity even in the event of multiple drive failures.
