RAID in Shared Hosting
All the content which you upload to your new shared hosting account will be stored on fast SSD drives that work in RAID-Z. This configuration is built to work with the ZFS file system which runs on our cloud Internet hosting platform and it adds an additional level of protection for your site content on top of the real-time checksum validation that ZFS uses to ensure the integrity of the data. With RAID-Z, the data is stored on a number of disks and at least one is a parity disk - whenever info is recorded on it, an extra bit is added, so in the event that any drive stops functioning for some reason, the integrity of the data can be verified by recalculating its bits based on what is kept on the production drives and on the parity one. With RAID-Z, the functioning of our system will never be interrupted and it will continue working smoothly until the problematic drive is replaced and the info is synced on it.
RAID in Semi-dedicated Hosting
If you host your websites inside a semi-dedicated hosting account from our company, any content which you upload will be kept on SSD drives which work in RAID-Z. With this type of RAID, at least 1 of the disks is used for parity - when data is synchronized between the disks, an additional bit is added to it on the parity one. The idea behind this is to guarantee the integrity of the info which is duplicated to a brand new drive if one of the drives in the RAID fails as the content being copied on the new disk is recalculated from the information 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 stops functioning, the system can easily switch to a different one right away without service disruptions of any sort. RAID-Z adds one more level of protection for the content that you upload on our cloud Internet hosting platform together with the ZFS file system that uses unique checksums so as to verify the integrity of each and every file.
RAID in VPS
The SSD drives which we use on the machines where we create virtual private servers work in RAID to ensure that any content you upload will be available and intact all the time. At least 1 drive is used for parity - one bit of information is added to any data cloned on it. In case a main drive breaks down, it is changed and the info which will be cloned on it is calculated between the other drives and the parity one. That’s done to make sure that the right data is copied and that no file is corrupted as the new drive will be incorporated into the RAID afterwards. Also, we use hard disks functioning in RAID on the backup servers, so in case you add this upgrade to your VPS package, you shall use an even more reliable Internet hosting service as your content will be available on multiple drives regardless of any type of unforeseen hardware failure.
