RAID in Cloud Hosting
The disk drives that we use for storage with our innovative cloud Internet hosting platform are not the traditional HDDs, but quick solid-state drives (SSD). They operate in RAID-Z - a special setup developed for the ZFS file system that we work with. All of the content that you upload to the cloud hosting account will be held on multiple hard drives and at least one of them will be used as a parity disk. This is a special drive where a further bit is added to any content copied on it. In case a disk in the RAID stops working, it'll be replaced without service disturbances and the data will be rebuilt on the new drive by recalculating its bits using the data on the parity disk plus that on the other disks. This is done in order to guarantee the integrity of the data and along with the real-time checksum verification which the ZFS file system runs on all drives, you won't ever need to concern yourself with the loss of any info no matter what.
RAID in Semi-dedicated Hosting
In case you host your websites in a semi-dedicated hosting account from our firm, all the content that you upload will be kept on SSD drives which operate in RAID-Z. With this form of RAID, at least one of the hard disks is used for parity - when data is synced between the drives, an additional bit is added to it on the parity one. The idea behind this is to ensure the integrity of the data which is cloned to a new drive in case one of the hard drives in the RAID fails as the content being copied on the brand new disk is recalculated from the information on the standard hard drives and on the parity one. An additional advantage of RAID-Z is the fact that even in case a disk drive fails, the system can switch to another one promptly without service disturbances of any type. RAID-Z adds an extra level of protection for the content you upload on our cloud Internet hosting platform along with the ZFS file system that uses unique checksums to validate the integrity of each file.
RAID in VPS Hosting
The SSD drives that we use on the machines where we generate 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 information is added to any data copied on it. In the event that a main drive breaks down, it is changed and the information which will be duplicated on it is calculated between the remaining drives and the parity one. This is done to ensure that the right info is copied and that not a single file is corrupted since the new drive will be a part of the RAID afterwards. Also, we use hard disks operating in RAID on the backup servers, so in the event that you add this upgrade to your VPS plan, you will use an even more reliable Internet hosting service since your content will be available on multiple drives regardless of any type of unexpected hardware failure.
