RAID in Cloud Website Hosting
All of the content that you upload to your new cloud website hosting account will be held on quick SSD 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 website content on top of the real-time checksum validation that ZFS uses to guarantee the integrity of the data. With RAID-Z, the info is saved on a couple of disks and at least one of them is a parity disk - whenever data is written on it, an extra bit is added, so if any drive stops working for whatever reason, the integrity of the data can be verified by recalculating its bits in accordance with what is saved on the production drives and on the parity one. With RAID-Z, the operation of our system won't be interrupted and it will continue operating smoothly until the problematic drive is replaced and the data is synchronized on it.
RAID in Semi-dedicated Servers
The RAID type that we employ for the cloud hosting platform where your semi-dedicated server account will be created is known as RAID-Z. What is different about it is that at least one of the disks is used as a parity drive. In simple terms, whenever any kind of data is copied on this special drive, one more bit is added to it and if a malfunctioning disk is replaced, the data that will be cloned on it is a mix of the data on the remaining hard drives in the RAID and that on the parity one. It's done this way to make sure that your data is intact. Throughout this process, your websites will be up and running normally since RAID-Z makes it possible for an entire drive to fail without any service interruptions and it simply works by using one of the other ones as the main production drive. Employing RAID-Z together with the ZFS file system that uses checksums to guarantee that no data shall get silently corrupted on our servers, you won't ever need to worry about the integrity of your files.
RAID in VPS Servers
All VPS server accounts which our company offers are created on physical servers which use SSD drives operating in RAID. At least one drive is employed for parity - one additional bit is added to the info duplicated on it and if a main disk stops working, this bit makes it much simpler to recalculate the bits of the files on the failed drive so that the right info is restored on the new drive included in the RAID. Meanwhile, your Internet sites will remain online since all the data will still load from at least one more hard disk. In case you add routine backups to your VPS plan, a copy of the information will be stored on standard disk drives that also function in RAID because we would like to make sure that any type of website content you add will be risk-free all of the time. Using multiple hard drives in RAID for all the main and backup servers enables us to offer fast and reliable Internet hosting service.
