A peripheral proxy subsystem is placed between multiple hosts, each having a root controller, and single root I/O virtualization (SR-IOV) peripheral devices that are to be shared. The peripheral proxy subsystem provides a root controller for coupling to the endpoint of the SR-IOV peripheral device or devices and multiple endpoints for coupling to the root controllers of the hosts. The peripheral proxy subsystem maps the virtual functions of an SR-IOV peripheral device to the multiple endpoints as desired to allow the virtual functions to be allocated to the hosts. The physical function of the SR-IOV peripheral device is managed by the peripheral proxy device to provide the desired number of virtual functions. The virtual functions of the SR-IOV peripheral device are then presented to the appropriate host as a physical function or a virtual function.

The storage device may be configured to receive the continuous authentication signal through the second physical connection. The decryption unit may be configured to decrypt the continuous authentication signal. When the second physical connection is tampered with, the storage device may stop processing the I/Os.

Access to peripherals can be managed in a containerized environment. A management service can be employed on a computing device to detect when a container is created. When a container is created or a peripheral is connected, the management service can determine that an application running within the container should be allowed to access a peripheral. The management service can then interface with a peripheral mapper running within the container to enable the application to access the peripheral. A peripheral access manager can also be employed to isolate the peripheral to the container.

Creating hybrid virtual devices using a plurality of physical functions. A processor of a device may identify a plurality of physical functions accessible to the device, the plurality of physical functions including a first physical function and a second physical function. The processor may create a virtual device to comprise the first physical function to provide a first capability and the second physical function to provide a second capability, wherein the first capability and second capability are different capabilities.

An expander I/O module discovery/management system includes a secondary system chassis housing an expander I/O module coupled to a server device. The server device identifies the secondary system chassis and an expander I/O module port utilized by that server device, and then generates and transmits an expander I/O module reporting communication identifying the secondary system chassis and the expander I/O module port. A primary system chassis houses a switching I/O module coupled to the expander I/O module. The switching I/O module receives the expander I/O module reporting communication and determines that the secondary system chassis identified in the expander I/O module reporting communication is different than the primary system chassis. In response, the switching I/O module assigns a virtual slot to the expander I/O module, and assigns a virtual port associated with the virtual slot to the expander I/O module port identified in the expander I/O module reporting communication.
