RAID in Cloud Hosting
All the content which you upload to your new cloud hosting account will be held on quick SSD drives which work in RAID-Z. This setup is built to use the ZFS file system which runs on our cloud hosting platform and it adds an additional level of security for your site content on top of the real-time checksum verification which ZFS uses to guarantee the integrity of the data. With RAID-Z, the information is stored on several disks and at least one of them is a parity disk - whenever data is written on it, an extra bit is added, so in the event that any drive stops functioning for some reason, the stability of the info can be verified by recalculating its bits based on what is kept on the production drives and on the parity one. With RAID-Z, the functioning of our system won't be interrupted and it will continue operating flawlessly until the problematic drive is replaced and the information is synced on it.
RAID in Semi-dedicated Servers
The RAID type that we employ for the cloud Internet hosting platform where your semi-dedicated server account will be created is named RAID-Z. What is different about it is that at least 1 of the disks is used as a parity drive. In simple terms, whenever any kind of data is copied on this specific hard drive, one more bit is added to it and in case a problematic disk is changed, the info which will be cloned on it is a combination of the data on the remaining hard drives in the RAID and that on the parity one. This is done to make sure that the data is intact. Throughout this process, your Internet sites will be up and running normally since RAID-Z allows for an entire drive to fail without service disruptions and it simply uses one of the remaining ones as the main production drive. Employing RAID-Z together with the ZFS file system which uses checksums to ensure that no data shall get silently corrupted on our servers, you won't have to worry about the integrity of your files.
RAID in VPS Servers
In case you employ one of our VPS server plans, any content that you upload will be stored on SSD drives that function in RAID. At least 1 drive is intended for parity to ensure the integrity of your info. In simple terms, this is a special drive where data is copied with one bit added to it. In case a disk within the RAID fails, your Internet sites will continue working and when a new disk takes the place of the malfunctioning one, the bits of the information that will be cloned on it are calculated using the healthy and the parity drives. By doing this, any probability of corrupting data during the process is avoided. We also use conventional hard disks that operate in RAID for storing backup copies, so should you include this service to your VPS plan, your content will be saved on multiple drives and you'll never need to worry about its integrity even in the event of multiple drive failures.
