Dell Host Bus Adapter User's Guide HBA 355 and 350 Series

Supported Cable Configurations

  • Connect to the JBOD EMM by using SAS4 cables only.
  • Redundant cable configurations only:
    • Both EMMs must be cabled to the PERC or HBA in a server to properly manage the JBOD.
    • All elements cannot be monitored in single cable configuration. For example, fans, temperature, and probes.
    • Firmware of both EMMs cannot be upgraded in a single cable configuration. Peer update functionality is unavailable in JBOD.
    • DUP supports only dual cable configurations.
  • Symmetrical cable configurations only:
    • Chain configurations do not support asymmetrical cabling. All cables will run top to bottom or bottom to top in a stack.
  • Mixing of enclosures in chain configuration is not supported:
    • You must connect enclosures of same model only. For example, an MD2412 can be daisy-chained only to an MD2412 enclosure.
