RAID in Shared Web Hosting
All content that you upload to your new shared web hosting account will be held on quick SSD drives that function in RAID-Z. This setup is built to work with the ZFS file system that runs on our cloud Internet hosting platform and it adds an additional level of protection for your content in addition to the real-time checksum verification that ZFS uses to ensure the integrity of the data. With RAID-Z, the information is saved on several disks and at least one is a parity disk - whenever data is written on it, an additional bit is added, so if any drive fails for whatever reason, the integrity of the information can be verified by recalculating its bits based on what is saved on the production drives and on the parity one. With RAID-Z, the functioning of our system will not be interrupted and it'll continue operating effectively until the faulty drive is changed and the information is synchronized on it.
RAID in Semi-dedicated Hosting
In case you host your Internet sites inside a semi-dedicated hosting account from our company, any content which you upload will be kept on SSD drives that work in RAID-Z. With this form of RAID, at least one of the hard drives is used for parity - when data is synchronized between the drives, an extra bit is added to it on the parity one. The reasoning behind this is to guarantee the integrity of the data which is cloned to a new drive in the event that one of the drives in the RAID breaks down as the content being copied on the brand 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 if a drive fails, the system can easily switch to a different one immediately without service disruptions of any kind. RAID-Z adds one more level of security for the content which you upload on our cloud web hosting platform along with the ZFS file system which uses unique checksums to authenticate the integrity of every single file.
RAID in VPS Web Hosting
The physical servers where we create virtual private server use extremely fast SSD drives which will increase the speed of your Internet sites significantly. The disk drives operate in RAID to make sure that you won't lose any info because of a power loss or a hardware malfunction. The production servers work with multiple drives where the info is kept and one disk is used for parity i.e. one bit is added to all the information copied on it, that makes it easier to recover the website content without any loss if a main drive fails. In case you choose our backup service, the info will be saved on an independent machine that uses standard hard-disk drives and though there's no parity one in this case, they are also in a RAID to make sure that we will have a backup copy of your website content all of the time. With this type of setup your information will always be safe because it will be available on a lot of drives.
