RAID in Cloud Hosting
Any content which you upload to your new cloud hosting account will be held on fast SSD drives that function in RAID-Z. This configuration is built to use the ZFS file system that runs on our cloud hosting platform and it adds one more level of security for your website content in addition to the real-time checksum validation which ZFS uses to ensure the integrity of the data. With RAID-Z, the info is stored on a number of disks and at least one of them is a parity disk - whenever info is written on it, an extra bit is added, so in case any drive stops functioning for some reason, the stability of the info can be verified by recalculating its bits in accordance with what is saved on the production hard disks and on the parity one. With RAID-Z, the functioning of our system won't be interrupted and it will continue operating effectively until the malfunctioning drive is changed and the info is synchronized on it.
RAID in Semi-dedicated Servers
If you host your sites in a semi-dedicated server account from our company, all of the content you upload will be saved on SSD drives that work in RAID-Z. With this type of RAID, at least 1 of the hard disks is used for parity - when data is synced between the hard drives, an extra bit is added to it on the parity one. The purpose behind this is to ensure the integrity of the information that is cloned to a brand new drive if one of the hard drives in the RAID breaks down because the content being copied on the new disk is recalculated from the info on the standard drives and on the parity one. Another advantage of RAID-Z is that even in the event that a disk drive stops working, the system can easily switch to another one promptly without service interruptions of any kind. RAID-Z adds one more level of safety for the content which you upload on our cloud web hosting platform in addition to the ZFS file system which uses unique checksums to validate the integrity of each file.
RAID in VPS Servers
The physical servers where we generate VPS server employ quick SSD drives that will increase the speed of your sites significantly. The hard drives work in RAID to guarantee that you will not lose any data as a result of a power loss or a hardware breakdown. The production servers employ multiple drives where the information is stored and one disk is used for parity i.e. one bit is added to all of the data copied on it, which makes it much easier to restore the content without loss in the event a main drive breaks down. In case you take advantage of our backup service, your information will be kept on a separate machine that uses standard hard-disk drives and although there is no parity one in this case, they are also in a RAID to guarantee that we will have a backup of your site content at all times. With this configuration your data will always be safe since it will be available on many disk drives.
