PCI Performance

Electrical and Environmental Specifications

Physical Dimensions

PCI-Express connection is made through the edge connector. The component height on the top and bottom of the board follows the PCI-Express specifications.

TABLE A-1 Physical Dimensions
Dimension	Board
Length	6.6 inches/16.8 cm
Width	2.713 inches/6.9 cm
Low-profile mounting bracket	3.118 inches/7.9 cm
Standard height mounting bracket	4.725 inches/12 cm

Connectors

This section provides a description of the connectors on the HBA.

PCI-Express connector -- The PCI-Express interface has eight PCI-Express lanes, which provide possible host-side maximum transmission and reception rates of up to 4.0 Gbytes/s. The HBA supports x8, x4, and x1 PCI-Express link widths, and automatically downshifts if plugged into x8 connector with 4 active lanes. The connection is made through the edge connector. The signal definitions and pin numbers conform to the PCI-Express specifications.

SAS/SATA connectors -- The SAS connections are SFF-8088 mini-SAS external right-angle connectors.

PCI Performance

PCI performance features of the HBA include:

Provides eight PCI-Express PHYs

Supports x8, x4, and x1 link widths

Supports serial, point-to-point interconnections between devices

Supports lane reversal and polarity inversion

Supports PCI-Express Hot Plug

Supports Power Management

Supports 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 during times of no link activity

Contains a replay buffer that preserves a copy of the data for retransmission in case a CRC error occurs

Supports the PCI-Express Advanced Error Reporting capabilities

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

Supports Traffic Class 0 and one 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

Electrical and Environmental Specifications

The design and implementation of the HBA minimizes electromagnetic emissions, susceptibility to radio frequency energy, and the effects of electrostatic discharge. The board carries the CE mark, C-Tick mark, Canadian Compliance Statement, Korean MIC, Taiwan BSMI, Japan VCCI, FCC Class B, and is marked with the FCC Self-Certification logo. The board also meets the requirements of CISPR Class B.

Electrical Characteristics

TABLE A-2 lists the maximum power requirements for the HBA under normal operation.

TABLE A-2 Maximum Power Requirements
PCI Express +12.0 V	Power	Operating Range
0.5 A	6.0 W	0 ˚C to 60 ˚C

Thermal and Atmospheric Characteristics

TABLE A-3 lists the tempearature and humidity ranges supported by the HBA.

TABLE A-3 HBA Temperature and Humidity Ranges
Measure	Operating Range
Temperature range	0˚C to 60˚C (32˚F to 140˚F) (dry bulb)
Relative humidity range	5% to 90% noncondensing
Maximum dew point temperature	32˚C (89.6˚F)
Storage and transit temperature range	-45˚C to +105˚C (-49˚F to 221˚F) (dry bulb)
Storage and Transit humidity range	5% to 90% noncondensing

Safety Characteristics

The HBA meets or exceeds the requirements of UL flammability rating 94V-0. Each bare board is marked with the supplier’s name or trademark, type, and UL flammability rating. Because these boards are installed in a PCI-Express bus slot, all voltages are below the SELV 42.4 V limit.
