RAID in Cloud Web Hosting
The drives which we employ for storage with our ground-breaking cloud Internet hosting platform are not the classic HDDs, but high-speed solid-state drives (SSD). They work in RAID-Z - a special setup created for the ZFS file system that we work with. All of the content that you add to the cloud web hosting account will be saved on multiple hard drives and at least one of them will be employed as a parity disk. This is a specific drive where an extra bit is added to any content copied on it. If a disk in the RAID stops functioning, it will be replaced without any service disruptions and the information 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 in order to ensure the integrity of the info and together with the real-time checksum verification that the ZFS file system executes on all drives, you will never need to concern yourself with the loss of any information no matter what.
RAID in Semi-dedicated Hosting
The information uploaded to any semi-dedicated hosting account is saved on SSD drives which operate in RAID-Z. One of the drives in this kind of a configuration is used for parity - each time data is cloned on it, an extra bit is added. If a disk happens to be problematic, it will be removed from the RAID without interrupting the operation of the sites as the data will load from the remaining drives, and when a new drive is included, the information that will be cloned on it will be a blend between the data on the parity disk and data stored on the other hard drives in the RAID. This is done in order to guarantee that the information that is being cloned is accurate, so the moment the new drive is rebuilt, it can be included in the RAID as a production one. This is an extra warranty for the integrity of your data because the ZFS file system that runs on our cloud Internet hosting platform compares a special checksum of all of the copies of the files on the various drives in order to avoid any chance of silent data corruption.
RAID in VPS
The physical servers where we create virtual private server work with quick SSD drives which will boost the speed of your sites noticeably. The hard disks operate in RAID to guarantee that you won't lose any info as a result of a power loss or a hardware breakdown. The production servers employ multiple drives where the info is stored and one disk is used for parity i.e. one bit is added to all information copied on it, which makes it easier to restore the content without any loss in case a main drive stops working. In case you pick our backup service, the information will be saved on a separate machine which uses standard hard-disk drives and even though there's no parity one in this case, they are also in a RAID to ensure that we will have a backup copy of your content at all times. With this type of setup your information will always be safe since it will be available on multiple drives.
