Peripheral component interconnect (pci) hosting device

A method comprising:

• coupling a plurality of component interconnect (PCI) interfaces of a PCI hosting device to a plurality of server devices, each PCI interface being designed to be coupled to one server device from the plurality of server devices;
• registering the PCI hosting device as a first PCI board for a first server device through a first PCI interface and as a second PCI board for a second server device through a second PCI interface once the first and second server devices are coupled to the PCI hosting device;
• supplying power to the plurality of PCI interfaces, by a power supply of the PCI hosting device independently from one or more power supplies to supply power to the plurality of server devices;
• and
• forwarding packets in PCI express (PCIe) protocol between one or more network interfaces and a first domain that includes the first server device and the first PCI interface, and between the one or more network interfaces and a second domain that includes the second server device and the second PCI interface, wherein packets in each of the first and second domains are unavailable to server devices outside that domain.

A non-transitory machine-readable storage medium storing instructions, when executed by a processing circuit, causing the processing circuit to perform:

• coupling a plurality of component interconnect (PCI) interfaces of a PCI hosting device to a plurality of server devices, each PCI interface being designed to be coupled to one server device from a plurality of server devices;
• registering the PCI hosting device as a first PCI board for a first server device through a first PCI interface and as a second PCI board for a second server device through a second PCI interface once the first and second server devices are coupled to the PCI hosting device;
• supplying power to the plurality of PCI interfaces, by a power supply of the PCI hosting device independently from one or more power supplies to supply power to the plurality of server devices;
• and
• forwarding packets in PCI express (PCIe) protocol between one or more network interfaces and a first domain that includes the first server device and the first PCI interface, and between the one or more network interface and a second domain that includes the second server device and the second PCI interface, wherein packets in each of the first and second domains are unavailable to server devices outside that domain.
