RAID, which stands short for Redundant Array of Independent Disks, is a software or hardware storage virtualization technology which enables a system to use multiple hard drives as a single logical unit. Simply put, all the drives are used as one and the info on all of them is the same. This type of a setup has 2 major advantages over using a single drive to keep data - the first is redundancy, so if one drive doesn't work, the information will be accessible through the remaining ones, and the second is better performance since the input/output, or reading/writing operations will be spread among different drives. You can find different RAID types based on what number of drives are used, whether reading and writing are both performed from all drives concurrently, if data is written in blocks on one drive after another or is mirrored between drives in the same time, etc. Depending on the particular setup, the error tolerance and the performance may differ.

RAID in Cloud Hosting

All content that you upload to your new cloud hosting account will be placed on quick SSD drives that work in RAID-Z. This setup is built to employ the ZFS file system which runs on our cloud hosting platform and it adds an additional level of security for your website content on top of the real-time checksum authentication that ZFS uses to guarantee the integrity of the data. With RAID-Z, the info is stored on a number of disks and at least one is a parity disk - whenever information is recorded on it, an extra bit is added, so if any drive fails for whatever reason, the stability of the info can be verified by recalculating its bits in accordance with what is stored on the production hard drives and on the parity one. With RAID-Z, the functioning of our system won't be interrupted and it will continue operating smoothly until the problematic drive is changed and the data is synchronized on it.

RAID in Semi-dedicated Hosting

If you host your Internet sites in a semi-dedicated hosting account from our firm, any content that you upload will be saved on SSD drives which work in RAID-Z. With this type of RAID, at least one of the hard disks is used for parity - when data is synchronized between the drives, an additional bit is included in it on the parity one. The idea behind this is to guarantee the integrity of the information which is duplicated to a new drive in case one of the drives in the RAID stops working since the content being copied on the new disk is recalculated from the data on the standard disk drives and on the parity one. An additional advantage of RAID-Z is the fact that even in case a hard drive fails, the system can switch to another one right away without service disruptions of any sort. RAID-Z adds one more level of security for the content you upload on our cloud web hosting platform along with the ZFS file system that uses unique checksums so as to authenticate the integrity of each and every file.

RAID in VPS Web Hosting

The SSD drives that we use on the physical machines where we set up virtual private servers work in RAID to make sure that any content you upload will be available and intact all of the time. At least a single drive is employed for parity - one bit of information is added to any data cloned on it. In case a main drive fails, it is replaced and the info which will be copied on it is calculated between the rest of the drives and the parity one. It's done this way to make sure that the correct data is copied and that not a single file is corrupted since the new drive will be a part of the RAID afterwards. We also use hard drives working in RAID on the backup servers, so in the event that you add this upgrade to your VPS plan, you shall use an even more reliable Internet hosting service as your content will be available on multiple drives regardless of any sort of unforeseen hardware failure.
