EonStor CS 3000

Scale-out Enterprise NAS storage


Scale-out Enterprise NAS storage


EonStor CS is a scale-out NAS storage system that addresses the significantly rising amount of unstructured data faced by modern enterprises. It provides high performance, large capacity, and solid data protection along with flexible scalability. Initial deployment can start with only one CS appliance, allowing you to add more nodes to the cluster later on to increase performance and capacity on demand. All your CS storage nodes form a cluster under one single namespace to eliminate data silos.

Superior performance and scalability make CS suitable for a wide range of data-intensive applications and industries, such as media and entertainment (M&E), high performance computing (HPC), video surveillance archiving, file sharing, and data backup.

The EonStor CS 3000 is a scale-out enterprise NAS storage solution for growing networks offering the best cost/performance ratio. Equipped with 8-core processor, EonStor CS 3000 features linear-increasing performance and instant horizontal capacity scalability with minimized deployment/management efforts, complete data protection.

High Performance Enterprise Storage Server

EonStor CS delivers up to 100+ GBps throughput that best suits large file applications. The high-end U.2 NVMe all-flash series provides better performance at a lower latency with up to 6 GB/s read and 4.5 GB/s write speeds per node.

By clustering multiple nodes under a single namespace and automatically balancing data across different nodes, CS solves the problem of single node performance limitations and effectively improves access efficiency.
