A data communication network (DCN) having a plurality of network devices coupled to the DCN with at least one of the network devices having a “boot once” connectivity manager processor (CMP). The CMP receives its power over the DCN rather than from the power applied to the network devices. The CMP can execute special operating system code and maintain network connectivity even if the network device itself is powered off, is being booted or is otherwise non-functional. The CMP is also coupled to the network device's memory so that it may respond to out-of-band polling requests for device status information from network management tools. With CMP, network administrators can monitor the boot process of network devices, determine that a network device is non-functional due to power loss and can maintain an accurate inventory status of spare network devices that are stored un-powered in a spares closet.

To effect a block data transfer between a plurality of physical I/O devices coupled through interfaces to an I/O channel ("IOC") bus, a source logical device is established by programmably assigning to each of the physical device interfaces a logical device identifier, a leaf identifier determining when the physical device participates relative to the first data transfer in the block data transfer, a burst count specifying the number of consecutive transfers for which the physical device is responsible when its interleave period arrives, and an interleave factor identifying how often the physical device participates in the block data transfer. A destination logical device is similarly established. The source and logical devices are then activated to accomplish a block transfer of data between them. To permit different I/O processors to operate independently in making I/O requests, requests from each I/O processor are communicated to an IOC controller over another bus, which need not be a high performance bus, and are serviced to construct header packets in a transaction buffer identifying IOC transactions, including source and destination logical devices.
