Why to use RAID storage for your data

RAID is, of course, a Redundant Array of Independent (or Inexpensive) Disks. It is a method of storing information on multiple hard disks for greater protection and in some cases performance. Under the RAID umbrella are a number of different storage methods, called levels and numbered from 0 to 9, some of which are more useful than others. Why to use RAID storage RAID was created to combine multiple, less-expensive drives into a single, higher-capacity and/or faster volume. On top of that, it was designed to facilitate redundancy, also known as fault tolerance or failover protection, so that the array and its data remain usable when a drive fails.

You’ll often hear about 1-disk or 2-disk redundancy, which refers to the number of drives that can fail while the array remains viable. Each level is a distinct method of organizing storage, but some of them can be combined which produces a two-digit RAID level, such as RAID 10, sometimes identified (and more appropriately so) as RAID 1+0. In general, each RAID level has its own advantages and disadvantages.

 

RAIDRAID10 10, for example, is fast, its crash proof and it eats disk space. If you need more protection for your storage, or faster storage performance, RAID 10 is a simple, relatively cheap fix. To implement RAID 10 you need at least two physical hard drives; just using two partitions on the same hard drive is inadequate. You also need a disk controller that understands RAID. RAID 10 works by striping and mirroring your data across at least two disks.

 

Mirroring, or RAID 1, means writing your data to two or more disks at the same time. Even if one disk fails completely, the mirror preserves the information. Striping, or RAID 0, means breaking your data up into chunks and writing the chunks to different disks in succession. It improves performance because the computer can get data off more than one disk simultaneously. (For the purists out there: RAID 0 technically isn’t a RAID level at all because it doesn’t provide any redundancy to protect information. However, it is commonly referred to as a RAID level anyway.) Put RAID 1 and RAID 0 together and you get RAID 10. RAID 10 is secure because mirroring duplicates all your data. It’s fast because the data is striped across two or more disks, meaning chunks of data can be read and written to different disks simultaneously. The drawback to RAID 10 is that it cuts your effective disk space in half. Since everything is mirrored (duplicated), two 60 GB disks give you a total system capacity of 60 GB. And remember, always use identical disks when creating a mirrored array. The disk geometry (number of heads, cylinders, etc.) is critical, and using disks that are different is discouraged in the strongest terms. Given the cost of disks, storage space is much less of a problem than it was a few years ago. RAID-5

It’s cheap enough to add additional disks to support your RAID 10 array and if the disk controller on your motherboard doesn’t support RAID 10, you can get an add-in disk controller card for less than $50. RAID 10 is also slightly more complex to set up than conventional storage, but it isn’t particularly hard. The system or disk controller software includes install routines that will walk you through the process. It usually takes just a few minutes to install a RAID 10 array.

What Webhosts Do When Server Recovery Is Needed

server recoveryWhen data loss occurs due to unprecedented situations, like viruses and logical failures, website owners can recover lost data through the help of data recovery services. Most data recovery companies have an in-house team of trained and qualified engineers and developers who have years of experience in providing customized solutions to clients.

Data recovery specialists are capable of retrieving lost data from file servers, restoring lost web server data, and recovering virtual server data. In the event of server crashes and data loss, data recovery services help restore any lost data through the use of cutting edge server recovery technology. When server recovery is needed, web hosts provide a diagnostic report of all available recoverable data, letting the website owner know of the extent of the recovery. The best services offer a guarantee of their services knowing that they can deliver excellent results.

There are various options for recovering inaccessible or lost data from servers. Data recovery engineers can retrieve data depending on the situation, configuration, and kind of storage system. Before hiring the services of recovery specialists, it’s important to provide information about the server make, model or brand, operating system, and cause of the server data loss. Experienced data recovery specialists can handle the most complex and challenging situations, such as data loss due to viruses, mechanical failures, power loss, and natural disasters.

A reliable web host has qualified and trained data recovery specialists who undergo advanced data recovery research and development. These experts tackle server recovery by using sophisticated technology in laboratories. They examine the make, model, and manufacturer of the client’s computer hardware and storage systems, and they go beyond the operating system level to retrieve data from systems. They ensure that all possible recoverable data are restored. Some companies provide free analysis and file listing to customers.

Overall, web hosts are capable of handling data loss that occurred due to hard drive failure, physical damage from flood or fire, incorrect re-initialization of the RAID, or damage to the container information.

seeing them, it’s obvious that you need to see an expert for your system. These may include some signs like having a corruption on the hard disk, if your server was displaying a kind of error message at the time its booting up, and when there is a failure in the components of the hard drive. With a good web host you will be able to have server recovery without having many challenges.
