HBA Specifications

The chapter contains the specifications for the Sun StorageTek PCI-X SAS 8-Channel HBA.

This appendix discusses the following topics:

Physical Dimensions

Connectors

PCI Performance

Electrical and Environmental Specifications

Physical Dimensions

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

TABLE A-1 Physical Dimensions
Dimension	Measurement
Length	6.6 inches/16.8 cm
Width	2.536 inches/6.4 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 three connectors on the HBA. See FIGURE A-1 for connector locations.

PCI-X connector -- The PCI-X interface operates as a 32-bit or 64-bit DMA bus master. The connection is made through the internal connector, which is a +3.3 V type board edge connector. The signal definitions and pin numbers conform to the PCI-X specifications. See FIGURE A-1 for connector locations.

SAS connectors -- The SAS connections are SFF-8088 mini-SAS external right-angle connectors. FIGURE A-1 Internal and External Connectors

Figure shows the location of the external SAS connectors and PCI-X connector.

PCI Performance

PCI features of the HBA include:

Supports a 133-MHz, 64-bit PCI-X interface that does the following:

Operates up to 133 MHz PCI-X

Operates at 33 MHz or 66 MHz PCI

Supports 32-bit or 64-bit data transfers

Supports 32-bit or 64-bit addressing through Dual Address Cycles (DAC)

Provides a theoretical 1064 Mbytes/s PCI bandwidth

Complies with the PCI Local Bus Specification, revision 3.0

Complies with the PCI-X Addendum to the PCI Local Bus Specification, revision 2.0

Complies with the PCI Bus Power Management Interface Specification, revision 1.2

Complies with the PC2001 Specification

Provides high throughput and low CPU utilization to offload the host processor

Presents a single electrical load to the PCI Bus

Reduces Interrupt Service Routine (ISR) overhead with interrupt coalescing

Supports 32-bit or 64-bit data bursts with variable burst lengths

Supports the PCI Cache Line Size register

Supports the PCI Memory Write and Invalidate, Memory Read Line, and Memory Read Multiple commands

Supports the PCI-X Memory Read Dword, Split Completion, Memory Read Block, and Memory Write Block commands

Supports 16 PCI-X Split Transaction cycles

Supports backward compatibility with previous revisions of the PCI specification

Provides a full 32-bit or 64-bit PCI-X DMA bus master

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-X +3.30 V	Power	Operating Range
0.97 A	7.5 W	0 °C to 60 °C

The PCI-X PRSNT1# and PRSNT2# pins are set to indicate 7.5W maximum configuration at board build time.

Thermal and Atmospheric Characteristics

TABLE A-3 HBA Temperature and Humidity Ranges
Measure	Parameters
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	-40°C to +105°C (-40°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 or PCI-X bus slot, all voltages are below the SELV 42.4 V limit.
