RAID in Website Hosting
The hard disks which we use for storage with our innovative cloud web hosting platform are not the standard HDDs, but high-speed solid-state drives (SSD). They work in RAID-Z - a special setup designed for the ZFS file system that we employ. All the content that you upload to the website hosting account will be kept on multiple hard drives and at least one shall be used as a parity disk. This is a special drive where an extra bit is included to any content copied on it. In the event that a disk in the RAID stops functioning, it'll be changed with no service interruptions and the data will be rebuilt on the new drive by recalculating its bits using the data on the parity disk plus that on the remaining disks. This is done so as to ensure the integrity of the information and together with the real-time checksum validation which the ZFS file system executes on all drives, you won't ever have to concern yourself with losing any info no matter what.
RAID in Semi-dedicated Hosting
The RAID type which we use for the cloud Internet hosting platform where your semi-dedicated hosting account shall be created is referred to as RAID-Z. What is different about it is that at least one of the disks is used as a parity drive. Simply put, whenever any data is duplicated on this particular drive, one more bit is added to it and in case a problematic disk is replaced, the info that will be copied on it is a combination 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 the data is intact. Throughout this process, your sites will be functioning normally as RAID-Z enables an entire drive to fail without service disruptions and it simply works by using one of the remaining ones as the main production drive. Using RAID-Z together with the ZFS file system which uses checksums to warrant that no data can get silently corrupted on our servers, you won't have to worry about the integrity of your files.
RAID in VPS
All virtual private server accounts which we offer are created on physical servers that employ SSD drives working in RAID. At least 1 drive is intended for parity - one extra bit is added to the information duplicated on it and if a main disk stops working, this bit makes it easier to recalculate the bits of the files on the failed drive so that the accurate info is restored on the new drive added to the RAID. At the same time, your Internet sites will remain online because all the information will still load from at least 1 other drive. In case you add regular backups to your VPS plan, a copy of your data will be kept on standard hard disks which also function in RAID because we would like to make certain that any content you upload will be safe and sound all of the time. Employing multiple hard drives in RAID for all of the main and backup servers permits us to offer fast and reliable hosting service.
