RAID in Shared Web Hosting
The advanced cloud hosting platform where all shared web hosting accounts are generated uses quick SSD drives instead of the traditional HDDs, and they work in RAID-Z. With this setup, multiple hard disk drives function together and at least 1 is a dedicated parity disk. Basically, when data is written on the rest of the drives, it's cloned on the parity one adding an extra bit. This is done for redundancy as even in case some drive fails or falls out of the RAID for whatever reason, the data can be rebuilt and verified using the parity disk and the data recorded on the other ones, which means that not a thing will be lost and there will not be any service disorders. This is another level of protection for your info together with the top-notch ZFS file system which uses checksums to ensure that all the data on our servers is intact and is not silently corrupted.
RAID in Semi-dedicated Hosting
The SSD drives which are used for keeping any site content uploaded to the semi-dedicated hosting accounts that we offer operate in RAID-Z. This is a specific setup where one or more hard drives are employed for parity i.e. the system will add an additional bit to any data copied on this kind of a hard drive. In the event that a disk fails and is substituted with another one, what info will be duplicated on the latter shall 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 data on the new drive shall be correct. During the procedure, the RAID will continue operating adequately and the malfunctioning drive won't impact the normal operation of your websites in any respect. Using SSDs in RAID-Z is a superb addition to the ZFS file system that runs on our revolutionary cloud platform with respect to preserving the integrity of your files since ZFS uses specific digital identifiers identified as checksums in order to prevent silent data corruption.
RAID in VPS Web Hosting
The SSD drives that we use on the machines where we set up virtual private servers operate in RAID to make sure that any content which you upload will be available and intact at all times. At least a single drive is employed for parity - one bit of data is added to any data copied on it. If a main drive fails, it is changed and the data which will be duplicated on it is calculated between the other drives and the parity one. It's done this way to make sure that the correct information is copied and that no file is corrupted as the new drive will be incorporated into the RAID afterwards. We also use hard disks functioning in RAID on the backup servers, so in the event that you add this upgrade to your VPS package, you shall use an even more reliable hosting service because your content will be available on multiple drives irrespective of any sudden hardware malfunction.
