RAID in Cloud Hosting
The SSD drives that our cutting-edge cloud Internet hosting platform employs for storage function in RAID-Z. This kind of RAID is created to work with the ZFS file system which runs on the platform and it works by using the so-called parity disk - a special drive where info saved on the other drives is duplicated with an extra bit added to it. If one of the disks fails, your websites shall continue working from the other ones and once we replace the problematic one, the data that will be duplicated on it will be recovered from what is stored on the rest of the drives together with the information from the parity disk. This is done so as to be able to recalculate the elements of each file correctly and to confirm the integrity of the info duplicated on the new drive. This is one more level of security for the information you upload to your cloud hosting account in addition to the ZFS file system which analyzes a special digital fingerprint for each and every file on all the drives in real time.
RAID in Semi-dedicated Hosting
The info uploaded to any semi-dedicated hosting account is kept on SSD drives which work in RAID-Z. One of the drives in type of a setup is used for parity - whenever data is copied on it, an additional bit is added. In case a disk happens to be problematic, it will be removed from the RAID without interrupting the work of the sites as the data will load from the other drives, and when a brand new drive is added, the info that will be cloned on it will be a combination between the data on the parity disk and data stored on the other drives in the RAID. That is done to guarantee that the information which is being duplicated is correct, so once the new drive is rebuilt, it can be incorporated into the RAID as a production one. This is one more warranty for the integrity of your info as the ZFS file system which runs on our cloud Internet hosting platform analyzes a unique checksum of all of the copies of your files on the separate drives to avoid any chance of silent data corruption.
RAID in VPS
The physical servers where we make virtual private server work with high-speed SSD drives which will boost the speed of your sites considerably. The drives operate in RAID to ensure that you will not lose any info because of a power loss or a hardware breakdown. The production servers take advantage of a variety of drives where the information is saved and one disk is used for parity i.e. one bit is added to all of the data copied on it, that makes it easier to recover the site content without loss in case a main drive breaks down. In case you pick our backup service, your data will be saved on an individual machine which uses standard hard-disk drives and even though there isn't a parity one in this case, they are also in a RAID to guarantee that we will have a backup copy of your website content at all times. With this type of setup your info will always be safe as it will be available on several drives.
