RAID in Hosting
The SSD drives which our cutting-edge cloud Internet hosting platform uses for storage work in RAID-Z. This type of RAID is developed to work with the ZFS file system that runs on the platform and it works by using the so-called parity disk - a specific drive where data kept on the other drives is cloned with an additional bit added to it. If one of the disks fails, your websites will continue working from the other ones and as soon as we replace the bad one, the info that will be duplicated on it will be rebuilt from what is stored on the remaining drives along with the info from the parity disk. This is done so as to be able to recalculate the bits of every single file adequately and to confirm the integrity of the data cloned on the new drive. This is one more level of security for the information you upload to your hosting account in addition to the ZFS file system that compares a unique digital fingerprint for each and every file on all hard drives in real time.
RAID in Semi-dedicated Servers
The SSD drives which are used for keeping any site content uploaded to the semi-dedicated server accounts which we offer operate in RAID-Z. This is a special setup where one or more disk drives are used for parity i.e. the system will include an additional bit to any data copied on this kind of a drive. In case 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 other disks and that on the parity one. This is done to ensure that the info on the new drive will be accurate. Throughout the procedure, the RAID will continue operating normally and the problematic drive will not impact the proper operation of your sites in any respect. Using SSDs in RAID-Z is an impressive addition to the ZFS file system which runs on our advanced cloud platform in terms of preserving the integrity of your files since ZFS uses specific digital identifiers identified as checksums so as to prevent silent data corruption.
RAID in VPS Servers
The physical servers where we create VPS server work with fast SSD drives that will increase the speed of your Internet sites significantly. The hard disks work in RAID to make sure that you won't lose any data due to a power loss or a hardware failure. The production servers employ a variety of drives where the data is kept and one disk is used for parity i.e. one bit is added to all info copied on it, that makes it easier to recover the website content without loss if a main drive stops working. If you choose our backup service, the info will be saved on an individual machine which uses standard hard-disk drives and even though there's no parity one in this case, they are also in a RAID to make sure that we will have a backup of your website content at all times. With this configuration your information will always be safe since it will be available on several drives.
