RAID in Cloud Hosting
The drives that we employ for storage with our top-notch cloud Internet hosting platform are not the classic HDDs, but extremely fast solid-state drives (SSD). They operate in RAID-Z - a special setup intended for the ZFS file system that we employ. All the content that you add to the cloud hosting account will be held on multiple disk drives and at least one of them shall be employed as a parity disk. This is a specific drive where an additional bit is included to any content copied on it. In case a disk in the RAID stops functioning, it'll be replaced without service interruptions and the information will be recovered on the new drive by recalculating its bits using the data on the parity disk along with that on the remaining disks. This is done so as to guarantee the integrity of the info and along with the real-time checksum verification that the ZFS file system performs on all drives, you will never need to concern yourself with losing any info no matter what.
RAID in Semi-dedicated Hosting
If you host your websites inside a semi-dedicated hosting account from our firm, all the content that you upload will be saved on SSD drives which work in RAID-Z. With this kind of RAID, at least one of the hard drives is used for parity - when data is synced between the drives, an additional bit is included in it on the parity one. The reasoning behind this is to ensure the integrity of the information which is cloned to a brand new drive if one of the disks in the RAID fails because the website content being copied on the brand new disk is recalculated from the information on the standard drives and on the parity one. Another advantage of RAID-Z is the fact that even if a drive stops working, the system could switch to a different one immediately without service disturbances of any sort. RAID-Z adds an additional level of safety for the content you upload on our cloud hosting platform together with the ZFS file system that uses unique checksums so as to validate the integrity of each file.
RAID in VPS Hosting
The SSD drives that we use on the physical machines where we generate virtual private servers work in RAID to ensure that any content you upload will be available and intact at all times. At least one drive is employed for parity - one bit of data is added to any data copied on it. In case a main drive stops working, it is changed and the information that will be copied on it is calculated between the remaining drives and the parity one. It's done this way to make sure that the right data is copied and that not a single file is corrupted because the new drive will be included in the RAID afterwards. In addition, we use hard disks functioning in RAID on the backup servers, so in the event that you add this upgrade to your VPS package, you will use an even more reliable web hosting service since your content will be available on multiple drives irrespective of any type of unforeseen hardware malfunction.
