RAID in Cloud Hosting
The SSD drives that our cutting-edge cloud web hosting platform employs for storage operate in RAID-Z. This sort of RAID is designed to work with the ZFS file system which runs on the platform and it works by using the so-called parity disk - a specific drive where information located on the other drives is cloned with an additional bit added to it. If one of the disks fails, your sites shall continue working from the other ones and as soon as we replace the bad one, the info which will be copied on it will be rebuilt from what is stored on the other drives as well as the data from the parity disk. This is done in order to be able to recalculate the bits of every single file properly and to validate the integrity of the data cloned on the new drive. This is one more level of security for the information which you upload to your cloud hosting account together with the ZFS file system which compares a unique digital fingerprint for each file on all the disk drives in real time.
RAID in Semi-dedicated Servers
The SSD drives that are used for saving any website content uploaded to the semi-dedicated server accounts that we offer work in RAID-Z. This is a specific configuration where one or more disk drives are used for parity i.e. the system will include an extra bit to any data duplicated on this kind of a disk drive. In case that a disk fails and is substituted with a new one, what data will be copied 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 guarantee that the information on the new drive shall be accurate. Throughout the process, the RAID will continue functioning normally and the faulty drive will not affect the proper operation of your Internet sites in any respect. Working with SSDs in RAID-Z is a great addition to the ZFS file system that runs on our cutting-edge cloud platform with regards to preserving the integrity of your files since ZFS uses unique digital identifiers called checksums to avoid silent data corruption.
RAID in VPS Servers
The physical servers where we generate VPS server employ super fast SSD drives that will increase the speed of your websites considerably. The hard disks work in RAID to ensure that you will not lose any info as a result of a power loss or a hardware failure. The production servers use many different drives where the information is saved and one disk is used for parity i.e. one bit is added to all data copied on it, which makes it much easier to recover the website content without any loss in the event a main drive breaks down. If you choose our backup service, the data will be saved on an individual machine that uses standard hard-disk drives and although there isn't a parity one in this case, they are also in a RAID to make sure that we will have a backup of your site content all the time. With this particular setup your info will always be safe since it will be available on multiple disk drives.
