RAID in Shared Hosting
The disk drives that we employ for storage with our revolutionary cloud Internet hosting platform are not the classic HDDs, but quick solid-state drives (SSD). They operate in RAID-Z - a special setup designed for the ZFS file system which we use. All the content that you add to the shared hosting account will be saved on multiple drives and at least one of them will be employed as a parity disk. This is a specific drive where a further bit is added to any content copied on it. If a disk in the RAID fails, it'll be changed without service disturbances and the info 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 to guarantee the integrity of the info and together with the real-time checksum validation that the ZFS file system runs on all drives, you won't ever have to worry about losing any data no matter what.
RAID in Semi-dedicated Hosting
The SSD drives which are used for keeping any site content uploaded to the semi-dedicated hosting accounts that we provide work in RAID-Z. This is a specific configuration where one or more drives are employed for parity i.e. the system will add an extra bit to any data duplicated on this type of a drive. In the event that a disk fails and is substituted with a new one, what information will be copied on the latter will be a mix calculated between the data on the remaining hard disks and that on the parity one. This is done to ensure that the information on the new drive shall be correct. During the process, the RAID will continue working normally and the malfunctioning drive won't affect the proper operation of your sites at all. Using SSDs in RAID-Z is an amazing addition to the ZFS file system that runs on our revolutionary cloud platform with regards to preserving the integrity of your files since ZFS uses unique digital identifiers known as checksums to prevent silent data corruption.
RAID in VPS Web Hosting
In case you use one of our virtual private server packages, any content you upload will be kept on SSD drives that function in RAID. At least a single drive is intended for parity so as to guarantee the integrity of your data. In simple terms, this is a special drive where data is copied with one bit added to it. In the event that a disk inside the RAID stops functioning, your websites will continue working and when a new disk takes the place of the malfunctioning one, the bits of the info that will be cloned on it are calculated using the healthy and the parity drives. By doing this, any possibility of corrupting data during the process is avoided. We also employ conventional hard disk drives that function in RAID for storing backup copies, so should you add this service to your VPS package, your website 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.
