Abstract
Techniques providing connectivity between a CPU and physical storage devices (PDs) can use a loop back path formed between two connectors of an extended PO slot when an extended I/O card is inserted therein. The two connectors can include a first connector having connectivity with the CPU over a first set of lanes, and a second connector having connectivity with the PDs over a second set of lanes. While the extended I/O card is inserted into the I/O slot, connectivity can be provided between the CPU and the PDs using connectivity provided between the CPU and the first connector and the first set of lanes; using the loop back path provided between the first and second connectors; and using connectivity provided between the second connector and the PDs over the second set of lanes.
