HA401-TU is a 4U high-availability (HA) server with 2 controller nodes and supports 24 3.5” SAS 12Gbs drives. Each controller node is equipped with an AIC Tucana server board that is powered by dual 3rd Gen Intel® Xeon® Scalable processors and Intel® C621A chipset, which supports UPI speed up to 11.2 GT/s. HA401-TU provides enterprise users with a number of crucial benefits. The redundant hardware components ensure that there is no single point of failure. With the hot-swappable functionality, the controller canisters protect enterprises from the loss of revenue that can occur when access to mission-critical data or applications is disrupted. Both controller nodes process data input/output (I/O) operations and users can experience simultaneous and balanced access to logical devices. In the event of failover, the secondary node will automatically take over the devices, client connections and all the processes and services running in the system. This high-availability design significantly enhances the overall performance of clusters, enabling seamless handling of demanding workloads.
