What is an Enclosure Fabric Module?

An Enclosure Fabric Module, as known as a DNode, connect the Storage Class Memory and QLC SSDs in the enclosure to the NVMe Fabric in each VAST Enclosure. Each Fabric Module provides multiple fabric connections (100Gbps Ethernet or Infiniband) and a PCIe switch complex that connects the fabric to all the SSDs in the enclosure. In the event of Fabric Module failure, the SSDs remain connected to the fabric via the surviving Fabric Module.
