Abstract
Disclosed are apparatus and methods for facilitating communication between two devices from two different VSANs by propagating each device's presence from a first VSAN to the other device's different VSAN using a network address translation (NAT) mechanism. For instance, a first device, such as a host H, from VSAN_A is allowed to access data from a second device, such as disk D, of VSAN_B by propagating Ds presence into VSAN_A and Hs presence into VSAN_B. This awareness is accomplished by propagating an identifier for each device into the edge VSAN of the other device, as well as into any transit VSAN. So as to not duplicate identifiers in any one of the VSANs, a device's presence is propagated into a particular VSAN by assigning an unused domain for use by such device in the particular VSAN.
