RAID in Shared Web Hosting
Our state-of-the-art cloud hosting platform where all shared web hosting accounts are generated employs super fast SSD drives rather than the classic HDDs, and they operate in RAID-Z. With this setup, multiple hard disks operate together and at least a single one is a dedicated parity disk. Simply put, when data is written on the rest of the drives, it's cloned on the parity one adding an extra bit. This is carried out for redundancy as even if some drive fails or falls out of the RAID for some reason, the information can be rebuilt and verified using the parity disk and the data saved on the other ones, so not a single thing will be lost and there will not be any service interruptions. This is another level of protection for your info together with the cutting-edge ZFS file system which uses checksums to guarantee that all data on our servers is intact and is not silently corrupted.
RAID in Semi-dedicated Hosting
The information uploaded to any semi-dedicated hosting account is saved on SSD drives which function in RAID-Z. One of the drives in this kind of a configuration is used for parity - every time data is copied on it, an extra bit is added. In case a disk happens to be faulty, it will be taken out of the RAID without interrupting the work of the sites as the data will load from the remaining drives, and when a brand new drive is added, the info that will be duplicated on it will be a combination between the info on the parity disk and data saved on the other hard drives in the RAID. That is done so as to ensure that the info which is being duplicated is accurate, so as soon as the new drive is rebuilt, it can be incorporated into the RAID as a production one. This is one more guarantee for the integrity of your info because the ZFS file system that runs on our cloud web hosting platform analyzes a special checksum of all of the copies of your files on the different drives so as to avoid any probability of silent data corruption.
RAID in VPS Web Hosting
The SSD drives which we use on the physical machines where we generate virtual private servers work in RAID to make sure that any content that you upload will be available and intact all the time. At least 1 drive is employed for parity - one bit of information is added to any data copied on it. In case a main drive breaks down, it is replaced and the data which will be duplicated on it is calculated between the rest of the drives and the parity one. That’s done to ensure that the required data is copied and that no file is corrupted as the new drive will be included in the RAID afterwards. In addition, we use hard disks functioning in RAID on the backup servers, so in case you add this upgrade to your VPS package, you will use an even more reliable hosting service as your content will be available on multiple drives irrespective of any sort of unforeseen hardware malfunction.
