RAID in Cloud Website Hosting
All content which you upload to your new cloud website hosting account will be placed on quick SSD drives that work in RAID-Z. This setup is built to employ the ZFS file system which runs on our cloud Internet hosting platform and it adds one more level of security for your 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 is a parity disk - whenever information is written on it, an extra bit is added, so if any drive stops functioning for some reason, the stability of the information can be verified by recalculating its bits based on what is saved on the production disks and on the parity one. With RAID-Z, the operation of our system will never be interrupted and it'll continue operating effectively until the faulty drive is changed and the info is synchronized on it.
RAID in Semi-dedicated Hosting
If you host your websites in a semi-dedicated hosting account from our company, all the content that you upload will be kept on SSD drives that work in RAID-Z. With this kind of RAID, at least 1 of the drives is used for parity - when data is synced between the hard drives, an extra bit is included in it on the parity one. The reasoning behind this is to ensure the integrity of the info which is duplicated to a new drive in the event that one of the hard drives in the RAID fails because the site content being copied on the new disk is recalculated from the info on the standard hard drives and on the parity one. Another advantage of RAID-Z is that even in the event that a disk drive stops functioning, the system can switch to a different one immediately without service disruptions of any kind. RAID-Z adds an extra level of safety for the content which you upload on our cloud hosting platform along with the ZFS file system which uses unique checksums so as to validate the integrity of each file.
RAID in VPS Web Hosting
The SSD drives that we use on the machines where we set up virtual private servers function in RAID to ensure that any content you upload will be available and intact at all times. At least one drive is employed for parity - one bit of info is added to any data copied on it. In case a main drive breaks down, it is replaced and the information which will be copied on it is calculated between the rest of the drives and the parity one. It's done this way 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. We also use hard disk drives functioning in RAID on the backup servers, so if you add this upgrade to your VPS plan, you shall use an even more reliable hosting service since your content will be available on multiple drives irrespective of any sort of unforeseen hardware failure.
