vCluster Distributed Storage

vCluster Distributed Storage is a distributed storage product with the best performance and the most complete functions in China. It has more than 100 functions than some popular open-source distributed software and more than 30 optimized functions. The vCluster distributed storage series has greatly improved storage efficiency, as it adopts an advanced distributed architecture that allocates one task to multiple storage nodes for parallel processing. Its stackable and modular design has improved the robustness and scalability of storage, which is in line with the IT architecture development trends for enterprise storage from now to the future.

Product advantages

Extreme performance

Fastest speed: Single storage with a maximum bandwidth of up to 1GB/s which is three times that of similar products.
Highest concurrency: A single system can support tens of thousands of rendering servers to read and write concurrently
Most complete function: most complete storage functions, including parallel storage, automatic hierarchy, and second deletion of massive small files

Extreme security

Flexible: support a variety of data protection modes, including snapshot, remote disaster tolerance, copy, and erasure.
Reliable: support disk-level, node-level, cabinet-level, and data center-level redundancy.
Fast: online automatic reconstruction and multi-node reconstruction of lost data at the same time, which is 10 times faster than RAID and has no impact on the front-end businesses.

Extreme compatibility

Storage type: support three storage types, respectively block level, object level, and file level.
Multi-client: support a variety of operating systems, such as Windows and Linux.
Interface protocol: support a great variety of protocols, including NFS, CIFS, iSCSI, HDFS, FTP, HTTP, S3, Swift, and POSIX
