RAID in Shared Hosting
All of the content that you upload to your new shared hosting account will be placed on quick NVMe drives which work in RAID-Z. This setup is built to use the ZFS file system that runs on our cloud hosting platform and it adds one more level of security for your content in addition to the real-time checksum authentication which ZFS uses to ensure the integrity of the data. With RAID-Z, the data is stored on a couple of disks and at least one is a parity disk - whenever info is recorded on it, an additional bit is added, so if any drive fails for some reason, the integrity of the info can be verified by recalculating its bits in accordance with what is kept on the production hard drives and on the parity one. With RAID-Z, the operation of our system will never be interrupted and it'll continue functioning effectively until the faulty drive is changed and the info is synchronized on it.
RAID in Semi-dedicated Servers
The information uploaded to any semi-dedicated server account is saved on NVMe drives that function in RAID-Z. One of the drives in this kind of a configuration is used for parity - any time data is copied on it, an additional bit is added. In case a disk happens to be flawed, it will be taken out of the RAID without interrupting the functioning of the sites as the data will load from the other drives, and when a brand new drive is added, the data which will be copied on it will be a mix between the info on the parity disk and data saved on the other drives in the RAID. That is done so as to ensure that the info that is being copied is accurate, so once the new drive is rebuilt, it can be integrated into the RAID as a production one. This is an additional warranty for the integrity of your data since the ZFS file system which runs on our cloud web hosting platform compares a unique checksum of all copies of your files on the separate drives in order to avoid any chance of silent data corruption.
RAID in VPS Servers
All VPS server accounts that our company provides are generated on physical servers that employ NVMe drives functioning in RAID. At least 1 drive is intended for parity - one extra bit is added to the information copied on it and if a main disk fails, this bit makes it easier to recalculate the bits of the files on the damaged hard disk so that the right data is restored on the new drive added to the RAID. Meanwhile, your Internet sites will still be online since all the data will still load from at least one more hard disk. If you add regular backups to your VPS package, a copy of your data will be stored on standard hard drives that also work in RAID since we would like to make sure that any sort of site content you upload will be safe and sound all the time. Using multiple hard drives in RAID for all main and backup servers permits us to offer fast and reliable hosting service.
