Abstract
A rack-mounted system includes a chassis, a switchless board disposed in the chassis, a midplane, and a plurality of device ports. The switchless board includes a baseboard management controller (BMC), a network repeater configured to transport network signals, and a PCIe switch configured to transport PCIe signals. Each of the plurality of device ports is configured to connect a storage device to the midplane and carry the network signals and the PCIe signals over the midplane. The storage device is configurable to operate in one of multiple storage protocol modes based on a type of the chassis. The network repeater of the switchless board is swappable with an Ethernet switch to provide a switching compatibility to the chassis using the same midplane. The storage device can operate in single-port and dual-port configurations.
