Raid disk calculator

RAID 0 splits data across drives, raid disk calculator, resulting in higher data throughput. The performance of this configuration is extremely high, but a loss of any drive in the array will result in data loss. This level is commonly referred to as striping. Compared to a single drive, this mode tends to raid disk calculator faster on reads, slower on writes.

Explore RAID products. Note that this setup results in a nested RAID. This means you're creating at least two RAID sets that sit within another. This calculator assumes you are creating a typical setup with two subsets, though it would be possible to create more with enough disks. Each drive is individual of each other and mounts as such. With Spanning, separate disks are "merged" into a single "logical" volume, so your system only mounts one volume. This is similar in capacity to RAID 0, although the data is not split across the drives.

Therefore it allows you to make an informed choice about the configuration of your next RAID array. It compares the following RAID levels:. If this is your first time configuring a RAID array, you might be unsure as to exactly what one is. Let's explain. In the early days of computing, mainframes used large and expensive hard disks , designed to be highly reliable. The thing is that when they fail everything fails eventually , all of the data would be lost unless you had a backup , and the expensive disk would need to be replaced. Soon cheaper hard drives came along, but they were not very reliable at all, with failures being all too common. What was the solution? Use many disks together, acting as one. It allows the creation of a single logical disk looks like one disk from the computer's point of view made up of many cheap hard drives. Now there are many ways to arrange and configure these inexpensive hard disks, depending on whether you want high performance e.

This section also shows the fault tolerance of the RAID. As long as no one mirror loses all its drives, the array will survive.

The calculator supports over the 10 major types of RAID setups. Various types of data units are supported for input, and while the cost is indicated in U. These can help you decide if the selected configuration is right for your particular case - be it for a server or a workstation. RAID stands for Redundant Array of Independent Disks, originally Redundant Array of Inexpensive Disks is a data storage virtualization technology that combines multiple physical disk drive components into one or more logical units. The purposes is to provide data redundancy, performance improvement, or in certain cases: both. The term was coined in a paper by Patterson at.

So, in the diagram above, odd-numbered blocks are written to disk 0 and even blocks to disk 1. If performance is most important, then RAID 0 is the right choice, as you can start with just two disks , making it the cheapest option. The techniques to achieve that are: mirroring , in which identical data is copied onto more than one drive; striping , which partitions each drive's storage space into units ranging from a sector up to several mb; parity - in which information is striped across each drive, allowing the RAID to continue working even if one drive were to fail. These are known as " RAID levels ", and we are going to explore what they are and their characteristics in the following sections. Theoretically, maximum read performance is a multiple equal to the number of drives in the array, and the write performance is a multiple equal to half the number of disks since the RAID writes each block twice. This calculator assumes you are creating a typical setup with two subsets, though it would be possible to create more with enough disks. RAID is no replacement for backup. RAID 0 is excellent for situations where you need maximum performance e. Check the graphs below the levels table for visuals. Use many disks together, acting as one.

The low ratio of parity to data means low redundancy overhead. RAID 5 provides fault tolerance and increased read performance.
