Connectivity is robust, featuring four 1GbE LAN ports and two USB 3.2 Gen 1 ports, while two PCIe Gen3 x8 slots provide the flexibility to add specialized network or storage cards. To prevent unexpected downtime, the unit is equipped with redundant power supplies. Measuring 88 mm in height and 724 mm in depth, this 14.5 kg server fits standard rack installations and comes complete with a rail kit and hardware installation tools. It is a reliable choice for IT administrators who need a scalable, enterprise-grade storage hub that maintains stability across a wide range of humidity and temperature conditions.
