Abstract
A storage cartridge may include a storage controller comprising a single PCIe port and a PCIe switch. The PCIe switch may include a first PCIe port communicatively coupled to a first PCIe fabric, a second PCIe port communicatively coupled to a second, different PCIe fabric, and a third PCIe port communicatively coupled to the single PCIe port of the storage controller. The first PCIe port and the second PCIe port may be configured to be selectively communicatively coupled to a non-transparent bridge (NTB) of the PCIe switch.
