RAID in Hosting
The disk drives that we employ for storage with our revolutionary cloud hosting platform are not the standard HDDs, but high-speed solid-state drives (SSD). They function in RAID-Z - a special setup intended for the ZFS file system that we use. All of the content that you add to the hosting account will be saved on multiple drives and at least one of them will be used as a parity disk. This is a special drive where a further bit is added to any content copied on it. In the event that a disk in the RAID stops functioning, it will be replaced without service disturbances and the data will be rebuilt on the new drive by recalculating its bits using the data on the parity disk plus that on the other disks. This is done in order to guarantee the integrity of the data and along with the real-time checksum verification which the ZFS file system executes on all drives, you won't ever have to worry about losing any information no matter what.
RAID in Semi-dedicated Hosting
The SSD drives that are used for holding any site content uploaded to the semi-dedicated hosting accounts which we offer function in RAID-Z. This is a special setup where one or more disk drives are employed for parity i.e. the system will add an additional bit to any data cloned on this type of a drive. In the event that a disk fails and is replaced with a new one, what information will be copied on the latter will be a mix calculated between the data on the other hard disks and that on the parity one. This is done to ensure that the information on the new drive will be correct. Throughout the process, the RAID will continue working normally and the faulty drive will not impact the adequate operation of your websites at all. Working with SSDs in RAID-Z is an amazing addition to the ZFS file system which runs on our state-of-the-art cloud platform with respect to preserving the integrity of your files as ZFS uses specific digital identifiers known as checksums to avoid silent data corruption.
RAID in VPS Hosting
If you take advantage of one of our virtual private server plans, any content that you upload will be saved on SSD drives which work in RAID. At least 1 drive is employed for parity 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 part of the RAID stops working, your sites will continue working and when a new disk substitutes the faulty one, the bits of the data that will be copied on it are calculated using the healthy and the parity drives. By doing this, any possibility of corrupting data during the process is averted. We also employ regular hard disk drives which function in RAID for storing backup copies, so if you include this service to your VPS package, your site content will be kept on multiple drives and you won't ever have to worry about its integrity even in the event of multiple drive failures.
