RAID in Shared Website Hosting
The state-of-the-art cloud Internet hosting platform where all shared website hosting accounts are generated uses fast SSD drives as opposed to the traditional HDDs, and they function in RAID-Z. With this configuration, a number of hard disks function together and at least one of them is a dedicated parity disk. Simply put, when data is written on the other drives, it is cloned on the parity one adding an extra bit. This is carried out for redundancy as even if a drive fails or falls out of the RAID for some reason, the information can be rebuilt and verified thanks to the parity disk and the data recorded on the other ones, so not a thing will be lost and there will not be any service disorders. This is another level of security for your data in addition to the revolutionary ZFS file system that uses checksums to ensure that all of the data on our servers is intact and is not silently corrupted.
RAID in Semi-dedicated Servers
The SSD drives which are used for saving any website content uploaded to the semi-dedicated server accounts which we provide work in RAID-Z. This is a specific configuration where one or more disk drives are employed for parity i.e. the system will include an additional bit to any data cloned on such a hard drive. In the event that a disk fails and is replaced with another one, what information will be duplicated 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. Throughout the process, the RAID will continue working adequately and the faulty drive won't affect the proper operation of your Internet sites in any way. Using SSDs in RAID-Z is an amazing addition to the ZFS file system which runs on our state-of-the-art cloud platform in terms of preserving the integrity of your files as ZFS uses unique digital identifiers called checksums to prevent silent data corruption.
RAID in VPS Servers
In case you take advantage of one of our VPS server solutions, any content you upload will be kept on SSD drives which work in RAID. At least one drive is employed for parity so as to ensure the integrity of your information. In simple terms, this is a special drive where info is copied with one bit added to it. In case a disk inside the RAID fails, your Internet sites will continue working and when a new disk substitutes the malfunctioning one, the bits of the info that will be duplicated on it are calculated by using the healthy and the parity drives. By doing this, any probability of corrupting data during the process is averted. We also employ ordinary hard disk drives which function in RAID for storing backups, so in case you add this service to your VPS package, your website content will be stored on multiple drives and you will never need to worry about its integrity even in the event of multiple drive failures.
