Abstract
Logical address space portions and virtual layer blocks (VLBs) can be partitioned into multiple sets. Each of multiple nodes in a system can be assigned exclusive ownership of one of the multiple sets. In at least one embodiment, for a read I/O which is received at a first node and directed to a logical address LAthat is owned by a second node, the first node can request that the second owning node perform resolution processing for LA. The second node can return either a VLB address or a PLB address based on whether the second node owns a VLB used in mapping LAto a corresponding physical location PAwhich includes content Cstored at LA. The second node can set a flag in its response to indicate whether a returned address is a VLB address or a PLB address.
