RAID in Shared Website Hosting
The SSD drives which our cutting-edge cloud web hosting platform uses for storage work in RAID-Z. This sort of RAID is designed to work with the ZFS file system that runs on the platform and it employs the so-called parity disk - a special drive where info stored on the other drives is cloned 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 faulty 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 every single file correctly and to verify the integrity of the data copied on the new drive. This is another level of security for the info that you upload to your shared website hosting account together with the ZFS file system that compares a unique digital fingerprint for each and every file on all disk drives in real time.
RAID in Semi-dedicated Hosting
The RAID type which we use for the cloud hosting platform where your semi-dedicated hosting account shall be created is called RAID-Z. What is different about it is that at least one of the disks is employed as a parity drive. In simple terms, whenever any data is duplicated on this particular drive, one more bit is included to it and in the event that a defective disk is replaced, the data which will be duplicated on it is a mix of the data on the other hard disks in the RAID and that on the parity one. We do this to make sure that your info is intact. Throughout this process, your Internet sites will be functioning normally since RAID-Z enables a whole drive to fail without service disturbances and it simply works by using one of the other ones as the main production drive. Using RAID-Z together with the ZFS file system that uses checksums to guarantee that no data will get silently corrupted on our servers, you will not have to worry about the integrity of your files.
RAID in VPS Hosting
The SSD drives that we use on the machines where we generate virtual private servers work in RAID to ensure that any content that you upload will be available and intact at all times. At least a single drive is used 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 cloned on it is calculated between the rest of the drives and the parity one. That’s done to ensure that the correct info is copied and that not a single file is corrupted as the new drive will be incorporated into the RAID afterwards. In addition, we use hard disk drives working in RAID on the backup servers, so in the event that you add this upgrade to your VPS package, you shall use an even more reliable Internet hosting service because your content will be available on multiple drives irrespective of any sort of unpredicted hardware malfunction.
