HBA Specifications

This appendix contains the specifications for the HBA. This appendix contains the following topics:

• Physical Dimensions

• PCI Performance

• SAS Port Bandwidths

• Environmental Requirements

• Characteristics of the HBA

Physical Dimensions

The HBA board is 4.5-in. x 5.5-in. The PCIe and SAS/SATA interface connections are through a mezzanine connector, J1. It conforms to the PCIe Card Electromechanical Specification 2.0.

PCI Performance

The PCI Express features of the HBA include the following:

• Provides a scalable interface

  • Single-lane aggregate bandwidth of up to 0.5 GB/s (500 MB/s)

  • Quad-lane aggregate bandwidth of up to 2 GB/s (2000 MB/s)

  • 8-lane aggregate bandwidth of up to 4.0 GB/s (4000 MB/s)

• Supports serial point-to-point interconnections between devices

• Supports lane reversal and polarity inversion

• Supports the PCI Express advanced error reporting capabilities

• Uses a packetized and layered architecture

• Achieves a high bandwidth per pin with low overhead and low latency

• PCI Express is software compatible with PCI and PCI-X software

  • Leverages existing PCI device drivers

  • Supports the memory, I/O, and configuration address spaces

  • Supports memory read/write transactions, I/O read/write transactions, and configuration read/write transactions

• Provides 4-KB of PCI configuration address space per device

• Supports posted and nonposted transactions

• Supports traffic class 0 and class 1 virtual channel

• Supports message signaled interrupts (both MSI and MSI-X) as well as INTx interrupt signaling for legacy PCI support

• Supports end-to-end CRC (ECRC) and advanced error reporting

SAS Port Bandwidths

The HBA supports narrow and wide ports, as described in the following table.

Environmental Requirements

The HBA environmental requirements are listed in HBA Environmental Specifications.

Characteristics of the HBA

The HBA provides 6 Gb SAS performance using the HBA controller for Oracle-specified servers. The board has on-board Flash ROM for firmware and BIOS, and NVSRAM for embedded mirroring. Each of the eight PHYs on the HBA is capable of 6 Gb, 3 Gb, or 1.5 Gb SAS or SATA link rates.

LEDs

The board has eight activity LEDs that blink green for SAS activity, eight port-fault LEDs that are solid yellow, indicating a faulty link in the port, and one Heartbeat LED that blinks green for firmware heartbeat and indicates the card is capable of general activity.

Connectors

This section provides a description of the different connectors on the host bus adapter.

• SAS/SATA and PCIe Mezzanine Connector (J1). Supports x8 PCIe interface and a x8 SAS/SATA interface.

• UART Connector (J4). Debug port requiring a special cable and Oracle support to gather detailed IOC status.

UART Connections lists the UART connections and their functions.
