6Storage fabricsThe following sections contain information about Dell EMC PowerEdge MX7000 storage fabrics.Storage fabricPower distributionThe internal connection of the storage subsystem in the MX7000 enclosure is referred to as Fabric C. This fabric is connected on theMain DB between sleds in the front of the MX7000 enclosure and I/O modules in the rear. The primary use cases for this fabric willbe for SAS or Fibre Channel storage connectivity, however other technologies could utilize this interconnect in the future.Each compute sled can support a Fabric-C Mezz card, which connects to each IOM through a x4 link. The SAS Fabric-C IOMsprovide flexible SAS switching between compute sleds and internal storage sleds (MX5016s) connected to the MX7000 enclosure.The fibre channel IOMs provide connectivity between compute sleds and external storage.Fabric-C IOM interconnectThere are several connections on the Main DB to enable communication between the IOMs. Between each pair of IOMs (C1 andC2), there is a link for intermodule communication. This link supports a x1 connection with each lane operating up to 10 Gbps perdirection. In addition , there are also handshake signals between the two modules to facilitate redundancy/failover or other module tomodule communication. The usage of these interconnects depends on the IOM design and its particular requirements.19
