Infortrend's distributed NAS cluster EonStor CS has three scale-out modes: erasure, replica, and NAS Scale-Out (called "dedicated mode" in this article). The proprietary mode is unique to Infortrend. In dedicated mode, CS has a higher space utilization, and the actual used space can reach 90% of the original capacity. In the case of limited cost, users can use more space. And the performance is higher, the read performance of CS single node can reach 3GB/s, the write performance of single node can reach 2.4 GB/s, and the write performance of single thread can reach 967 MB/s. You know, this is achieved under the condition of installing HDD, and the performance of a single node is even lower than that of other manufacturers' distributed all-flash clusters, but the user investment is greatly reduced. In erasure code mode, the read and write performance of single node can also reach 2.3GBps/1.36 GBps, and the performance of single thread writing 846MBps is at least two to four times better.

Users can also change the shared folder after it is set to dedicated mode. CS is an integrated cluster, and three scale-out modes can be used in the system at the same time. Under a single namespace, shared folders can use different extension modes. Users pay more attention to the performance or security of folders, and they are free to switch expansion modes according to their own needs. After switching, the path of the folder will not change and the transmission of data will not be affected in any way. This flexibility is not limited to scale-out. CS also supports vertical expansion. If users think that under the premise that CS can be used, the application needs a lot of space and the cost has to be controlled, they can choose to scale up and only add expansion cabinets to achieve the goal.

The reason why CS has so many innovations and highlights is that CS is an embedded storage system, from the underlying RAID to the distributed file system is all developed by Infortrend, achieving a comprehensive product. This is different from the ordinary distributed clusters on the market, our CS is a real whole, all the architectures are integrated in the controller, not cobbled together. In the deployment, users do not need to rely on professional engineers to enter the internal settings of the system through complex commands, but through our graphical management interface, according to the deployment wizard, simple to click to complete. The deployment process of the original few weeks has been reduced to only 20 or 30 minutes. Day-to-day management after deployment is also easier, and you no longer have to migrate the entire deployment just by changing simple settings. All the operations that users want can be realized in a unified management interface.

With CS, the performance of the distributed cluster remains stable after each shared folder is assigned quota space. In addition, the RAID independently developed by the underlying Infortrend is powerful, users are not aware of the impact on the entire cluster when the HDD is damaged, and the core components are designed with modular redundancy, so that CS has double insurance at the hardware level, completely eliminating the hidden danger of data loss, which is also the traditional advantage of Infortrend. On this basis, CS develops a dedicated mode in addition to erasure codes and copies, and makes embedded storage fully production. It not only greatly improves the reading and writing performance of single node and single thread, but also significantly reduces the difficulty of deployment and management. finally, it is free to switch between horizontal and horizontal, horizontal and vertical, and choose flexibly. It is these advantages and characteristics that make CS lead the distributed cluster market from the starting point.
