RAID in Shared Website Hosting
Any content which you upload to your new shared website hosting account will be held on quick SSD drives which operate in RAID-Z. This setup is built to use the ZFS file system that runs on our cloud web hosting platform and it adds one more level of protection for your site content in addition to the real-time checksum validation which ZFS uses to guarantee the integrity of the data. With RAID-Z, the information is saved on a couple of disks and at least one of them is a parity disk - whenever information is recorded on it, an extra bit is added, so in the event that any drive fails for some reason, the stability of the info can be verified by recalculating its bits based on what is stored on the production hard drives and on the parity one. With RAID-Z, the functioning of our system will never be interrupted and it will continue functioning efficiently until the faulty drive is changed and the information is synchronized on it.
RAID in Semi-dedicated Hosting
If you host your Internet sites in a semi-dedicated hosting account from our firm, any content you upload will be saved on SSD drives that work in RAID-Z. With this type of RAID, at least one of the hard drives is employed for parity - when data is synced between the disks, an extra bit is added to it on the parity one. The purpose behind this is to guarantee the integrity of the info that is copied to a brand new drive in case one of the disks in the RAID stops functioning because the website content being copied on the new disk is recalculated from the info on the standard hard drives and on the parity one. An additional advantage of RAID-Z is the fact that even in the event that a disk drive stops functioning, the system can switch to a different one instantly without service interruptions of any kind. RAID-Z adds an extra level of safety for the content you upload on our cloud Internet hosting platform in addition to the ZFS file system that uses unique checksums to verify the integrity of each file.
RAID in VPS
The SSD drives that we use on the physical machines where we create virtual private servers operate in RAID to ensure 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 data is added to any data cloned on it. In case a main drive breaks down, it is changed and the data which will be copied on it is calculated between the rest of the drives and the parity one. That’s done to make sure that the needed info is copied and that no file is corrupted as the new drive will be included in the RAID afterwards. In addition, we use hard disk drives working in RAID on the backup servers, so if you add this upgrade to your VPS package, you will use an even more reliable Internet hosting service as your content will be available on multiple drives irrespective of any unexpected hardware malfunction.
