RAID in Cloud Website Hosting
The hard drives which we use for storage with our top-notch cloud web hosting platform are not the traditional HDDs, but high-speed solid-state drives (SSD). They operate in RAID-Z - a special setup created for the ZFS file system which we use. All the content that you add to the cloud website hosting account will be stored on multiple disk drives and at least one of them shall be employed as a parity disk. This is a special drive where a further bit is added to any content copied on it. In the event that a disk in the RAID fails, it will be changed with no service interruptions and the information will be rebuilt on the new drive by recalculating its bits using the data on the parity disk plus that on the other disks. This is done in order to guarantee the integrity of the data and together with the real-time checksum verification that the ZFS file system executes on all drives, you'll never have to concern yourself with losing any info no matter what.
RAID in Semi-dedicated Servers
In case you host your websites in a semi-dedicated server account from our company, all of the content you upload will be kept on SSD drives which operate in RAID-Z. With this form of RAID, at least one of the disks is employed for parity - when data is synchronized between the drives, an additional bit is included in it on the parity one. The reasoning behind this is to guarantee the integrity of the information that is duplicated to a new drive if one of the drives in the RAID breaks down as the website content being copied on the new disk is recalculated from the data on the standard disk drives and on the parity one. Another advantage of RAID-Z is the fact that even in case a hard drive stops functioning, the system can switch to a different one quickly without service disruptions of any type. RAID-Z adds an extra level of security for the content you upload on our cloud Internet hosting platform along with the ZFS file system which uses unique checksums to authenticate the integrity of each and every file.
RAID in VPS Servers
The SSD drives that we use on the machines where we create VPS servers work in RAID to make sure that any content which you upload will be available and intact all the time. At least one drive is used for parity - one bit of information is added to any data cloned on it. In case a main drive breaks down, it is replaced and the information which will be duplicated on it is calculated between the remaining drives and the parity one. That’s done to make sure that the required info is copied and that not a single file is corrupted since the new drive will be a part of the RAID afterwards. Also, we use hard disks working in RAID on the backup servers, so in case you add this upgrade to your VPS plan, you shall use an even more reliable web hosting service because your content will be available on multiple drives irrespective of any kind of unexpected hardware malfunction.
