    EMC PowerPath provides failover capabilities and multiple path detection as well as dynamic load balancing between multiple ports on the same storage processor. However, direct-attached clusters supported by Dell connect to a single port on each storage processor in the storage system. Because of the single port limitation, PowerPath can provide only failover protection, not load balancing, in a direct-attached configuration.

  • Page 19: Cabling The Public Network

    Cabling the Public Network Any network adapter supported by a system running TCP/IP may be used to connect to the public network segments. You can install additional network adapters to support additional public network segments or to provide redundancy in the event of a faulty primary network adapter or switch port. Cabling the Private Network The private network connection to the nodes is provided by a different network adapter in each node.

    A direct-attached cluster configuration consists of redundant Fibre Channel host bus adapter (HBA) ports cabled directly to a Dell/EMC storage system. Direct-attached configurations are self-contained and do not share any physical resources with other server or storage systems outside of the cluster.
  • Page 21 Each cluster node attaches to the storage system using two multi-mode optical cables with LC connectors that attach to the HBA ports in the cluster nodes and the storage processor (SP) ports in the Dell/EMC storage system. These connectors consist of two individual Fibre optic connectors with indexed tabs that must be aligned properly into the HBA ports and SP ports.

  • Page 39: Implementing Zoning On A Fibre Channel Switched Fabric

    Zoning automatically and transparently enforces access of information to the zone devices. More than one PowerEdge cluster configuration can share Dell/EMC storage system(s) in a switched fabric using Fibre Channel switch zoning. By using Fibre Channel switches to implement zoning, you can segment the SANs to isolate heterogeneous servers and storage systems from each other.
