Flash PCIe and SAS cables – Models 980, 98B with HPFE Gen2

The tables in this topic show the point-to-point connections for flash PCIe and SAS cables on a Model 980 with HPFE Gen2, with or without expansion racks. For FC-AL and flash PCIe configurations with HPFE (Gen1), refer to FC-AL and Flash PCIe cables – Models 980, 98B.
Notes:
  • Racks are shown with the maximum number of HPFE Gen2 storage enclosures and device adapter cards. Your rack might contain fewer storage enclosures or device adapter cards.
  • The figures that follow show the maximum number of racks in a storage facility with these rack models.

Notes:
  • Only HPFE Gen2 PCIe and SAS details are shown.
  • For this model, physical locations are predefined for microbays, but not for HPFE Gen2 flash enclosures.
  • The HPFE Gen2 enclosure pair can be located in a different rack than the associated microbay pair.
  • The HPFE Gen2 enclosure locations are shown as Rn-Fxx (the upper enclosure of a pair) and Rn-Fyy (the lower enclosure of a pair).

Flash PCIe cables

  1. Flash PCIe cables and connectors are identified with a colored band matching the DA pair and two different color codes:
    • A colored band, corresponding to the color code of the DA pair, is found on each end of the cable near the connector. These color codes are shown in Figure 1.
    • The connector is color-coded to help prevent cross-cabling at the microbay adapter card or I/O enclosure PCIe and PCN card end. Connectors on cables attaching to Rx-Mxx-C1-T7 have white labels with black text, and connectors on cables attaching to Rx-Mxx-C2-T7 have black labels with white text. An example of this showing both cables attaching to a microbay adapter card pair is shown in Figure 2. This alternating color scheme is the same for all Flash PCIe cables, and is independent of the DA pair color code. Figure 3 and Figure 4 show the Flash PCIe cable connection ends.
  2. The black and white label at each end has a physical location code showing the "FROM" and "TO" end.

Flash SAS cables

  1. SAS cables and connectors are identified with two different color codes and a location designator:
    1. A colored band, corresponding to the color code of the DA pair, is found on each end of the cable near the connector. These color codes are shown in Figure 1.
    2. The connector itself is color coded to help prevent cross-cabling at the SAS expander card or device adapter card (DA) end. The connectors always appear in the following order:
      white (T1), green (T2), black (T3), and blue (T4)
      as shown in Figure 6 and Figure 7 . This color code is specific to each SAS expander card or DA, and is independent of the DA pair color code.
    3. A black or white label at each end of the cable shows a location designator (for example, 16A1). Both ends of the cable have the same location designator and DA pair color code. However, the connector at each end of the same cable usually does NOT have the same color code.
    4. The following alternating color scheme is the same for all Flash SAS cables, and is independent of the DA pair color code.
      • Connectors on cables that attach to Rx-Mxx-C1-Tx have white labels with black text.
      • Connectors on cables that attach to Rx-Mxx-C2-Tx have black labels with white text.
      • Connectors on cables that attach to Rx-Mxx-C1-Tx have white labels with black text.
      • Connectors on cables that attach to Rx-Mxx-C2-Tx have black labels with white text.

    An example of SAS cables and connectors that shows both ends of two SAS cables to an enclosure is shown in Figure 5.

  2. Location designators are in the form CTP, where:
    C
    Is the device adapter pair (16-23).
    T
    Is the port pair on the device adapter (A, B, a, b) (uppercase for left device adapter in pair, lowercase for right device adapter in pair).
    P
    Is the logical position of the downstream SAS expander card.
    Example: 16a1 is the link between device adapter R1-M02-C2-T1 and R1-F01-P1-C1-T2.
    16
    Device adapter pair 16
    a
    First port pair on right adapter of device adapter pair (lowercase a)
    1
    First SAS expander card
    The colored connector band plugged into R1-M02-C2-T1 (16a1) is white, while the colored connector band plugged into R1-F01-P1-C1-T2 (16a1) is green.
  3. The black and white label at each end may have a physical location code in addition to the location designator.
