RAID in Hosting
The drives that we employ for storage with our innovative cloud web 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 that we use. All the content that you upload to your hosting account will be saved on multiple disk drives and at least one will be used as a parity disk. This is a special drive where an extra bit is added to any content copied on it. If a disk in the RAID stops functioning, it'll be replaced without service disruptions and the data will be rebuilt 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 so as to guarantee the integrity of the data and together with the real-time checksum verification which the ZFS file system executes on all drives, you will never have to be concerned about losing any information no matter what.
RAID in Semi-dedicated Servers
The SSD drives which are used for keeping any content uploaded to the semi-dedicated server accounts which we offer operate in RAID-Z. This is a special configuration where one or more drives are used for parity i.e. the system will add an extra bit to any data cloned on this type of a hard drive. In case that a disk fails and is replaced with a new one, what info will be copied on the latter will be a combination calculated between the data on the other hard disks 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 working normally and the problematic drive will not impact the adequate operation of your sites at all. Working with SSDs in RAID-Z is an excellent addition to the ZFS file system which runs on our top-notch cloud platform in terms of preserving the integrity of your files because ZFS uses unique digital identifiers identified as checksums so as to prevent silent data corruption.
RAID in VPS Servers
In case you employ one of our VPS server plans, any content that you upload will be saved on SSD drives which work in RAID. At least one drive is intended for parity so as to guarantee the integrity of your info. In simple terms, this is a special drive where information is copied with one bit added to it. In the event that a disk within the RAID stops working, 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 copied on it are calculated using the healthy and the parity drives. By doing this, any probability of corrupting data during the process is avoided. We also employ ordinary hard disk drives which function in RAID for storing backups, so should you include this service to your VPS plan, your website content will be saved on multiple drives and you won't ever have to worry about its integrity even in the event of multiple drive breakdowns.
