EXPEDITING ADAPTER FAILOVER

摘要

Expediting adapter failover may minimize network downtime and preserve network performance. Embodiments may comprise copying a primary adapter memory of a failing primary adapter to a standby adapter memory of a standby adapter. Copying the memory may expedite TCP/IP offload adapter failover by maintaining TCP/IP stack and connection information. In several embodiments, Copy Logic may copy primary adapter memory to standby adapter memory. In some embodiments, Detect Logic may monitor primary adapter viability and may initiate failover. In additional embodiments, Assess Logic may assess whether the IO bus is operative permitting Direct Logic to copy adapter memory via, e.g., DMA. In other embodiments, Packet Logic may fragment primary adapter memory into network packets sent through the network to the standby adapter where Unpack Logic may unpack them into memory.
