RAID in Web Hosting
The hard drives that we use for storage with our top-notch cloud hosting platform are not the traditional HDDs, but high-speed solid-state drives (SSD). They operate in RAID-Z - a special setup designed for the ZFS file system which we use. Any content that you upload to the web hosting account will be stored on multiple hard drives and at least one of them will 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 fails, it'll be replaced without any service disturbances 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 guarantee the integrity of the info and together with the real-time checksum validation which the ZFS file system runs on all drives, you will never need to concern yourself with losing any data no matter what.
RAID in Semi-dedicated Hosting
In case you host your websites inside a semi-dedicated hosting account from our firm, all the content you upload will be held on SSD drives which operate in RAID-Z. With this kind of RAID, at least 1 of the drives is used for parity - when data is synced between the hard drives, an extra bit is added to it on the parity one. The idea behind this is to ensure the integrity of the info which is copied to a brand new drive in case one of the drives in the RAID stops functioning because the site content being copied on the new disk is recalculated from the information on the standard hard drives and on the parity one. An additional advantage of RAID-Z is the fact that even in case a hard drive stops functioning, the system can switch to a different one right away without service interruptions of any sort. RAID-Z adds one more level of safety for the content which you upload on our cloud web hosting platform together with the ZFS file system which uses unique checksums in order to verify the integrity of each file.
RAID in VPS Hosting
All virtual private server accounts which our company provides are made on physical servers that employ SSD drives working in RAID. At least one drive is used for parity - one extra bit is added to the info copied on it and in case a main disk breaks down, this bit makes it easier to recalculate the bits of the files on the failed disk drive so that the correct info is recovered on the new drive included in the RAID. Meanwhile, your websites will still be online because all the data will still load from at least one other disk drive. If you add routine backups to your VPS plan, a copy of your data will be stored on standard hard drives which also operate in RAID because we would like to make sure that any website content you add will be risk-free all the time. Employing multiple hard disks in RAID for all of the main and backup servers allows us to offer fast and reliable web hosting service.
