RAID in Hosting
All of the content which you upload to your new hosting account will be held on fast SSD drives which function in RAID-Z. This configuration is built to work with the ZFS file system which runs on our cloud web hosting platform and it adds one more level of security for your content on top of the real-time checksum validation that ZFS uses to ensure the integrity of the data. With RAID-Z, the information is stored on a number of disks and at least one is a parity disk - whenever information is recorded on it, an additional bit is added, so if any drive stops working for some reason, the stability of the information can be verified by recalculating its bits based on what is stored on the production drives and on the parity one. With RAID-Z, the functioning of our system won't be interrupted and it'll continue functioning efficiently until the problematic drive is changed and the information is synced on it.
RAID in Semi-dedicated Hosting
The SSD drives that are used for holding any content uploaded to the semi-dedicated hosting accounts that we provide 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 extra bit to any data cloned on this type of a hard drive. If a disk fails and is substituted with another one, what information will be duplicated on the latter will be a mix calculated between the data on the other drives and that on the parity one. This is done to make sure that the info on the new drive shall be correct. Throughout the process, the RAID will continue working normally and the malfunctioning drive won't affect the normal operation of your sites at all. Using SSDs in RAID-Z is a superb addition to the ZFS file system which runs on our cutting-edge cloud platform in terms of preserving the integrity of your files since ZFS uses specific digital identifiers named checksums so as to prevent silent data corruption.
RAID in VPS Hosting
The physical servers where we create virtual private server use fast SSD drives which will increase the speed of your Internet sites considerably. The hard drives function in RAID to guarantee that you will not lose any data because of a power loss or a hardware malfunction. The production servers take advantage of a variety of drives where the info is stored and one disk is used for parity i.e. one bit is added to all of the info copied on it, which makes it easier to restore the website content without loss in case a main drive stops working. If you pick our backup service, the information will be kept on a separate machine which uses standard hard-disk drives and 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 website content all the time. With this particular configuration your data will always be safe as it will be available on multiple disk drives.
