RAID in Cloud Website Hosting
Any content that you upload to your new cloud website hosting account will be placed on quick SSD drives which operate in RAID-Z. This setup is built to employ the ZFS file system which runs on our cloud Internet hosting platform and it adds one more 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 stored on a couple of disks and at least one of them is a parity disk - whenever info is written on it, an extra bit is added, so if any drive stops working for whatever reason, the stability of the data can be verified by recalculating its bits in accordance with what is saved on the production disks 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 malfunctioning drive is changed and the information is synchronized on it.
RAID in Semi-dedicated Servers
The RAID type that we use for the cloud hosting platform where your semi-dedicated server account will be created is referred to as RAID-Z. What's different about it is that at least one of the disks is employed as a parity drive. In simple terms, whenever any kind of data is duplicated on this particular hard drive, one more bit is included to it and in the event that a malfunctioning disk is changed, the info which will be duplicated on it is a mix of the data on the remaining hard drives in the RAID and that on the parity one. We do this to guarantee that your data is intact. Throughout this process, your sites will be working normally as RAID-Z enables an entire drive to fail without service disruptions and it simply uses one of the other ones as the main production drive. Employing RAID-Z together with the ZFS file system that uses checksums to warrant that no data will get silently corrupted on our servers, you won't ever have to worry about the integrity of your files.
RAID in VPS Servers
If you take advantage of one of our VPS server packages, any content that you upload will be saved on SSD drives which operate in RAID. At least one drive is used for parity so as to guarantee the integrity of the information. In simple terms, this is a special drive where information is copied with one bit added to it. If a disk within the RAID stops working, your sites will continue working and when a new disk substitutes the malfunctioning one, the bits of the information that will be duplicated on it are calculated using the healthy and the parity drives. By doing this, any probability of corrupting data throughout the process is avoided. We also employ ordinary hard disk drives that operate in RAID for storing backup copies, so in case you add this service to your VPS package, your site content will be kept on multiple drives and you'll never have to worry about its integrity even in the event of multiple drive failures.
