RAID in Shared Web Hosting
The SSD drives which our cutting-edge cloud hosting platform uses for storage function in RAID-Z. This sort of RAID is intended to work with the ZFS file system which runs on the platform and it employs the so-called parity disk - a specific drive where information stored on the other drives is cloned with an additional bit added to it. In the event that one of the disks fails, your Internet sites shall continue working from the other ones and after we replace the malfunctioning one, the information that will be duplicated on it will be recovered from what is stored on the rest of the drives as well as the data from the parity disk. This is performed in order to be able to recalculate the bits of every single file adequately and to confirm the integrity of the info duplicated on the new drive. This is an additional level of security for the information which you upload to your shared web hosting account together with the ZFS file system that compares a special digital fingerprint for each and every file on all hard drives in real time.
RAID in Semi-dedicated Hosting
The info uploaded to any semi-dedicated hosting account is saved on SSD drives that operate in RAID-Z. One of the drives in such a configuration is used for parity - each time data is copied on it, an extra bit is added. In case a disk turns out to be faulty, it will be removed from the RAID without disturbing the functioning of the websites as the data will load from the other drives, and when a new drive is included, the info which will be copied on it will be a combination between the information on the parity disk and data kept on the other hard disks in the RAID. That is done in order to ensure that the data that is being duplicated is accurate, so once the new drive is rebuilt, it can be included in the RAID as a production one. This is an additional warranty for the integrity of your info since the ZFS file system which runs on our cloud web hosting platform compares a special checksum of all of the copies of the files on the separate drives so as to avoid any probability of silent data corruption.
RAID in VPS Web Hosting
All virtual private server accounts that we provide are created on physical servers which use SSD drives functioning in RAID. At least one drive is intended for parity - one extra bit is added to the data duplicated on it and in case a main disk breaks down, this bit makes it much easier to recalculate the bits of the files on the failed drive so that the accurate information is restored on the new drive included in the RAID. At the same time, your websites will remain online as all the info will still load from at least one more disk drive. If you add regular backups to your VPS package, a copy of the information will be kept on standard hard drives that also operate in RAID because we would like to make certain that any type of website content you upload will be protected all the time. Employing multiple hard drives in RAID for all the main and backup servers permits us to offer fast and reliable hosting service.
