Infortrend Adds DNS Load Balancing Feature to Scale-out NAS EonStor

Infortrend Technology, Inc. adds DNS Load Balancing feature to its scale-out NAS EonStor.

With this support, I/O workloads can be evenly and automatically distributed for all deployed CS nodes. It increases data access performance and facilitates to smooth and uninterrupted workflows for performance-demanding applications like HPC, as well as 4K video editing, broadcasting, or real-time streaming in the M&E industry.

EonStor CS is a scale-out NAS, which can be expanded by demand up to 144 nodes in a cluster with a total of over 100GB/s throughput and 100PB capacity. DNS Load Balancing follows either of the 4 policies for optimized system resource utilization: storage node network connection number, CPU and throughput usage, or round-robin algorithm. DNS load balancing ensures that there is no overworked storage node or overloaded channel which helps to avoid bottlenecks and degraded performance.

DNS Load Balancing maximizes speed for client connections by the automatic allocation of client traffic to different network channels across the entire cluster: users just need to enter a hostname. Without it, load distribution could only be done manually by typing the IP-address of the storage node to get access to. If a single CS node goes down, DNS Load Balancing function redirects traffic to the remaining normally functioning nodes. And when a new CS storage node is added to the cluster, I/O workload is automatically shared between each node.

“To cope with increasing multiple client traffic of nowadays applications, we integrated DNS Balancing feature in our EonStor CS scale-out NAS. Automatic distribution of the workload among all the nodes in the cluster not only helps to increase performance and avoid channel/node overload but also ensures HA and allows seamless system expandability,” said Frank Lee, senior director, product planning.
