RAID in Cloud Hosting
The hard drives that we employ for storage with our ground-breaking cloud Internet 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 use. All the content that you upload to the cloud hosting account will be held on multiple hard disks and at least one will be employed as a parity disk. This is a specific drive where an extra bit is included to any content copied on it. In case a disk in the RAID stops functioning, it will be replaced without any service disruptions 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 ensure the integrity of the info and together with the real-time checksum authentication which the ZFS file system runs on all drives, you won't ever need to concern yourself with the loss of any information no matter what.
RAID in Semi-dedicated Servers
The RAID type that we employ for the cloud Internet hosting platform where your semi-dedicated server account shall be created is referred to as RAID-Z. What's different about it is that at least 1 of the disks is used as a parity drive. In simple terms, whenever any kind of data is cloned on this specific disk drive, one more bit is included to it and in case a problematic disk is replaced, the info which will be duplicated on it is a combination of the data on the other hard disks in the RAID and that on the parity one. We do this to make sure that the information is intact. During this process, your Internet sites will be up and running normally since RAID-Z allows for an entire drive to fail without service interruptions and it simply uses one of the other ones as the main production drive. Using RAID-Z together with the ZFS file system which uses checksums to warrant that no data shall get silently corrupted on our servers, you won't ever need to worry about the integrity of your files.
RAID in VPS Servers
All VPS server accounts which we provide are generated on physical servers which take advantage of SSD drives functioning in RAID. At least 1 drive is employed for parity - one extra bit is added to the data copied on it and in case a main disk breaks down, this bit makes it much simpler to recalculate the bits of the files on the failed drive so that the right data is restored on the new drive included in the RAID. Meanwhile, your websites will stay online because all the information will still load from at least 1 other hard disk. In the event that you add routine backups to your VPS plan, a copy of the data will be saved on standard hard disks which also operate in RAID as we want to make certain that any sort of site content you upload will be risk-free all the time. Employing multiple hard disks in RAID for all main and backup servers allows us to offer fast and reliable web hosting service.
