RAID in Website Hosting
The disk drives that we use for storage with our revolutionary cloud hosting platform are not the classic HDDs, but quick solid-state drives (SSD). They operate in RAID-Z - a special setup created for the ZFS file system that we employ. All the content that you upload to the website hosting account will be kept on multiple drives and at least one of them shall be used as a parity disk. This is a specific drive where an additional bit is included to any content copied on it. If a disk in the RAID stops functioning, it'll be changed with no service disruptions and the data will be recovered on the new drive by recalculating its bits using the data on the parity disk along with that on the other disks. This is done to ensure the integrity of the data and along with the real-time checksum authentication that the ZFS file system executes on all drives, you'll never have to worry about losing any info no matter what.
RAID in Semi-dedicated Hosting
The SSD drives which are used for storing any content uploaded to the semi-dedicated hosting accounts which we offer work in RAID-Z. This is a specific configuration where one or more disk drives are used for parity i.e. the system will include an additional bit to any data cloned on this type of a drive. If a disk fails and is substituted with a new one, what information will be cloned on the latter will be a mix calculated between the data on the other hard disks and that on the parity one. This is done to ensure that the data on the new drive will be accurate. During the process, the RAID will continue operating adequately and the faulty drive won't have an impact on the adequate operation of your sites by any means. Working with SSDs in RAID-Z is a fantastic addition to the ZFS file system that runs on our top-notch cloud platform in terms of preserving the integrity of your files since ZFS uses unique digital identifiers called checksums to avoid silent data corruption.
RAID in VPS Web Hosting
The SSD drives that we use on the machines where we generate virtual private servers operate in RAID to ensure that any content which you upload will be available and intact all of the time. At least one drive is used for parity - one bit of info is added to any data copied on it. In the event that a main drive stops working, it is changed and the data which will be cloned on it is calculated between the rest of the drives and the parity one. This is done to make sure that the required information is copied and that not a single file is corrupted because the new drive will be included in the RAID afterwards. Also, we use hard disks operating in RAID on the backup servers, so in the event that you add this upgrade to your VPS package, you shall use an even more reliable web hosting service since your content will be available on multiple drives regardless of any kind of unexpected hardware malfunction.
