RAID in Hosting
All the content which you upload to your new hosting account will be stored on fast SSD drives that operate in RAID-Z. This configuration is built to use the ZFS file system that runs on our cloud Internet hosting platform and it adds another level of security for your content in addition to the real-time checksum verification which ZFS uses to ensure the integrity of the data. With RAID-Z, the information is saved on a number of disks and at least one is a parity disk - whenever info is written on it, an additional bit is added, so in the event that any drive fails for some reason, the integrity of the information can be verified by recalculating its bits based on what is stored on the production hard drives and on the parity one. With RAID-Z, the functioning of our system will not be interrupted and it'll continue functioning effectively until the malfunctioning drive is changed and the data is synchronized on it.
RAID in Semi-dedicated Hosting
The SSD drives that are used for holding any website content uploaded to the semi-dedicated hosting accounts which we provide work in RAID-Z. This is a special configuration where one or more drives are employed for parity i.e. the system will add an extra bit to any data copied on this kind of a disk drive. In the event that a disk fails and is replaced with another one, what info will be duplicated on the latter shall be a combination calculated between the data on the remaining disks and that on the parity one. This is done to make sure that the info on the new drive will be accurate. During the process, the RAID will continue operating adequately and the faulty drive won't have an effect on the adequate operation of your Internet sites by any means. Working with SSDs in RAID-Z is a great addition to the ZFS file system that runs on our revolutionary cloud platform with regards to preserving the integrity of your files because ZFS uses special digital identifiers named checksums to prevent silent data corruption.
RAID in VPS
The SSD drives which we use on the physical 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 all the time. At least a single drive is used for parity - one bit of data is added to any data copied on it. In case a main drive breaks down, it is changed and the information which will be copied on it is calculated between the other drives and the parity one. It's done this way to make sure that the required information is copied and that no file is corrupted because the new drive will be a part of the RAID afterwards. Also, we use hard disks functioning in RAID on the backup servers, so if you add this upgrade to your VPS plan, you will use an even more reliable web hosting service since your content will be available on multiple drives irrespective of any sort of sudden hardware malfunction.
