RAID in Cloud Web Hosting
All the content that you upload to your new cloud web hosting account will be held on quick SSD drives which function in RAID-Z. This setup is built to use the ZFS file system that runs on our cloud Internet hosting platform and it adds an additional level of security for your content on top of the real-time checksum validation which ZFS uses to ensure the integrity of the data. With RAID-Z, the data is saved on several 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 working for some reason, the stability of the info can be verified by recalculating its bits in accordance with what is kept on the production disks and on the parity one. With RAID-Z, the functioning of our system won't be interrupted and it'll continue functioning efficiently until the faulty drive is replaced and the data is synchronized on it.
RAID in Semi-dedicated Servers
If you host your Internet sites within a semi-dedicated server account from our firm, any content which you upload will be held on SSD drives that work in RAID-Z. With this kind of RAID, at least 1 of the drives is employed for parity - when data is synced between the drives, an additional bit is included in it on the parity one. The reasoning behind this is to ensure the integrity of the data that is duplicated to a new drive in case one of the drives in the RAID fails because the content being copied on the new disk is recalculated from the information 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 quickly without service disruptions of any kind. RAID-Z adds an additional level of protection for the content you upload on our cloud Internet hosting platform in addition to the ZFS file system which uses unique checksums in order to validate the integrity of each and every file.
RAID in VPS Servers
The SSD drives that we use on the machines where we generate VPS servers operate in RAID to make sure that any content which you upload will be available and intact all the time. At least 1 drive is used for parity - one bit of info is added to any data copied on it. In case a main drive stops working, it is replaced and the data that will be copied on it is calculated between the remaining drives and the parity one. That’s done to ensure that the needed information is copied and that no file is corrupted as the new drive will be a part of the RAID afterwards. In addition, we use hard drives working in RAID on the backup servers, so in case you add this upgrade to your VPS package, you will use an even more reliable hosting service because your content will be available on multiple drives regardless of any kind of unexpected hardware malfunction.
