The HDB8231 HDEC Series

The HDB8231 single-segment backplane provides eighteen PCI Express Gen3 x16 slots for applications that require large numbers of COTS cards. Designed to integrate seamlessly into any 4U or 5U Trenton Systems rackmount chassis, the HDB8231 offers unparalled available bandwidth via the eighty (80) lanes of PCIe 3.0 provided by the HEP8225 System Host Board. The backplane’s architecture enables a switchless design, virtually eliminating data latency between the system’s PCIe option cards and processors onboard the System Host Board. ATX/EPS power connectors, three 12V AUX power connectors and a 4-position terminal block provide expanded power supply capability for demanding applications.

Key features of the HDB8231 Large Format Backplane include:

  • 2-x8 and 16-x4 PCIe gen 3 option card slots available:
    • 2  – x8 PCI Express 3.0 electrical
    • 16 – x4 PCI Express 3.0 mechanical
  • Numerous device I/O connections within each backplane segment simplifies system integration, and cable routing
    • 6 – SATA/600 connectors
    • 2 – USB3 interface header connections
    • 4 – USB2 interface ports
    • 1 – Serial port
    • 8 – System fan headers with built-in fan speed monitoring
  • Ideal large format backplane for supporting standard 5U rackmount computer chassis
  • Long life cycle with 7+ year backplane availability.
Trenton designs all of our HDEC Series system host boards and backplanes to fully support the PCI Express auto-training function that ensures SHB-to-option card communications regardless of PCI Express interface type or link width.  This SHB and backplane design feature maximizes system flexibility by enabling system support for standard PCIe 3.0, 2.0 or 1.1 option cards having various PCIe electrical interface link widths such as x16, x8, x4 and x1.

The HDB8231 HDEC Backplane is designed and manufactured in the USA, and backed by our 5-year factory warranty.

 

Tech Specs

Model Number

HDB8231

Form Factor

HDEC Series large format backplane supports one dual-processor HDEC Series SHB and up to eighteen PCI Express option cards. All card slots are designed for the Gen3 PCIe electrical interface and are equipped with x16 PCIe mechanical connectors. Two of these slots feature PCI Express x8 PCIe electrical interfaces.

The backplane’s sixteen remaining slots are driven by the SHB with a x4 electrical interfaces.

Mechanical

Board dimensions: 16.4″/417mm x 12.9″/328mm – large format, single segment
The nominal backplane thickness is 0.080”; however, the backplane mounting holes are recessed 0.018” on the bottom to provide an eff ective PCB thickness of 0.062” for use in the chassis design process.

Configuration

Two x8 and Sixteen x4 PCI  Express 3.0 (all x16 mechanical) slots, and all card slots are PCIe Gen3 capable.

Note 1: Backplane slots PCIe13 and PCIe14 are x8 slots.
