HBA Specifications

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

• Physical Characteristics

• PCI Performance

• SAS Port Bandwidths

• Environmental Requirements

• HBA Connectors

Physical Characteristics

The HBA board enclosure is 6.25 in. x 4.50 in. (not including the ejection lever). The enclosure conforms to the PCIe ExpressModule Elecromechanical Specifications.

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 2.0 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 PCI Express Hot-Plug and PCI power management 1.2

  • Supports active-state power management (ASPM), including the L0, L0s, L1 states, by placing links in a power-savings mode when there is no link activity

  • Contains a replay buffer that preserves a copy of the data for retransmission in case a cyclic redundancy check (CRC) error occurs

• 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

• Provides quality of service (QOS) link configuration and arbitration policies

• Supports traffic class 0 and class 1 virtual channels

• 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 6 Gb SAS Bandwidths.

Environmental Requirements

The HBA environmental requirements are listed in HBA Environmental Specifications.

HBA Connectors

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

• PCIe Connector (J6). Supports x8 interface. The PCIe connection is through the edge connector, J6, which provides connections on both the top (J6B) and the bottom (J6A) of the board. The signal definitions and pin numbers conform to the PCIe ExpressModule Card Electromechanical Specifications, Revision 1.0.

• UART Connector (J5). Debug port requiring a special cable and Oracle support to gather detailed IOC status.

• SAS/SATA Connectors (J3 and J7). Supports SAS connections through connectors J3 and J7. These connectors are SFF-8088 mini-SAS, external connectors.

UART Connections lists the UART connection Pins on the HBA.
