Methods and structure for utilizing a virtual Expansion ROM. One exemplary embodiment is a management device. The management device includes a memory, a Peripheral Component Interconnect Express (PCIe) link, and a processor. The memory stores Expansion Read-Only Memory (Expansion ROM) boot instructions for a host. The processor identifies devices in a PCIe hierarchy by transmitting PCIe enumeration requests via the PCIe link. The processor also generates a synthetic PCIe hierarchy that includes an added virtual Expansion ROM which is not present in the PCIe hierarchy, and provides responses describing the synthetic PCIe hierarchy to a host. Furthermore, the processor acquires PCIe read requests initiated by the host that are directed to the virtual Expansion ROM, and provides boot instructions to the host from the memory based on the PCIe read requests.

Virtual expansion ROM in a PCIe environment

A method, a cluster system, and a computer-readable medium for distributing data packets addressed to at least one virtual address over a communication network using a protocol, which allows for at least some content of the data packet to be encrypted, to a multiplicity of service nodes. The method includes receiving incoming data packets addressed to a virtual address through a packet analyzer and identifying whether the incoming data packets are encrypted. Each encryption data packet is forwarded to a decryption module and a decrypted data packet is returned. Based on the decrypted data packet, a scheduling decision is made by a scheduling module. Scheduling data is then combined with the originally received encrypted data packet such that the encrypted data packet can be forwarded to one service node for further processing.
