Data protection techniques for object storage systems
The storage systems are designed to store objects, profitably, a large amount of data for a very long period of time. However, it makes the traditional hard copy of security, if not impossible. To ensure that data is protected both disk failures such as corruption, providers use replication or erasure coding (or a combination of both).
Even if you are not considering the storage of objects, understanding the differences between these techniques of data protection it is important, because many primary storage arrangements are beginning to use them. We explore the pros and cons of each approach so you can determine which method of data protection is best for your data center.
Most objects storage systems and converged systems are based on storage architectures horizontal scale. These architectures are built around a group of servers that provide storage capacity and performance. Each time another node is added to the cluster, the performance and capacity of the array generally increases.
These systems require redundancy across multiple storage nodes, so if a node fails, the data can still be accessed. Typical RAID levels such as RAID 5 and RAID 6 are particularly ill-suited for the distribution of data across multiple nodes because of its slow reconstruction times.
