RAID in Cloud Web Hosting
The SSD drives that our cutting-edge cloud hosting platform employs for storage operate in RAID-Z. This kind of RAID is intended to work with the ZFS file system that runs on the platform and it takes advantage of the so-called parity disk - a special drive where data located on the other drives is copied with an extra bit added to it. In case one of the disks stops working, your Internet sites will continue working from the other ones and as soon as we replace the malfunctioning one, the data which will be copied on it will be recovered from what is stored on the remaining drives together with the data from the parity disk. This is performed in order to be able to recalculate the bits of each and every file adequately and to confirm the integrity of the info cloned on the new drive. This is an additional level of security for the content which you upload to your cloud web hosting account together with the ZFS file system that analyzes a special digital fingerprint for every single file on all the disk drives in real time.
RAID in Semi-dedicated Servers
If you host your sites inside a semi-dedicated server account from our company, any content you upload will be held on SSD drives which operate in RAID-Z. With this type of RAID, at least one of the drives is employed 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 information which is duplicated to a brand new drive if one of the disks in the RAID breaks down as the website content being copied on the new disk is recalculated from the info on the standard hard drives and on the parity one. Another 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 one more level of safety for the content you upload on our cloud web hosting platform along with the ZFS file system that uses unique checksums so as to verify the integrity of each file.
RAID in VPS Servers
The physical servers where we create VPS server use super fast SSD drives which will raise the speed of your Internet sites noticeably. 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 many different drives where the information is kept and one disk is used for parity i.e. one bit is added to all the data copied on it, that makes it much easier to recover the website content without any loss if a main drive fails. In case you take advantage of our backup service, the data will be stored on a separate machine that uses standard hard-disk drives and despite the fact that there is no parity one in this case, they are also in a RAID to ensure that we will have a backup of your site content at all times. With this particular configuration your info will always be safe since it will be available on multiple drives.
