Overview
155 Mbps ATM Adapter for use on HP Alpha Systems
 
Models
Currently Available Model PCI to 155 Mbps ATM MMF NIC with duplex SC 3X-DAPBA-FA
Retired / End-of-Life Models with limited quantity availability (March, 2004) PCI to 155 Mbps ATM UTP NIC with RJ45 3X-DAPBA-UA
PCI to 622 Mbps ATM MMF NIC with duplex SC 3X-DAPCA-FA
Introduction
The 3X-DAPBA-FA/UA and the 3X-DAPCA-FA PCI to ATM adapters provide ATM connectivity for HP Alpha systems. Based on the industry's most advanced ATM ASIC, NetPro, the PCI-to-ATM adapters provide the highest performance ATM capability available in the industry. They provide hardware support for available bit rate (ABR), variable bit rate (VBR), constant bit rate (CBR), and unspecified bit rate (UBR). Using this ASIC chip, voice, video, and data can be carried simultaneously via high-performance networks and systems. Together, the 64-bit PCI adapter and 64-bit Alpha CPU create the most efficient, high-performance ATM application solution platforms available in the industry. In addition, the universal 32/64-bit, 33/66 MHz PCI bus interface makes the adapter usable on any 32-bit PCI compliant host system.
The advanced technology integrates dual intelligent DMA channels, a 32-/64-bit, 33-/66-MHz PCI bus interface, and either a 155 Mbps capable OC3 or 622 Mbps capable OC12 ATM PHY. It is these powerful hardware based protocol accelerator features that enable the PCI-to-ATM adapters to deliver the highest lines rates and consume the least host CPU overhead.

Performance
Full-duplex support allows the HE high-performance ATM adapters to transmit and receive data simultaneously at rates up to 266 Mbps for OC3 and up to 1064 Mbps for OC12. System level performance is further enhanced with up to 2 MB of buffer memory, which allows for reduced CPU overhead and higher sustainable line rates.
ATM Segmentation and Reassembly
The high-performance ATM adapters can do concurrent segmentation and reassembly on up to 4K ATM virtual connections.
Programmable Threshold Interrupt Mechanisms
The host can set a threshold interrupt level to minimize the number of interrupts received by the host processor, protecting the system from being overrun by excessive transmit and receive interrupts.
Local Memory
The ASIC provides a 32-bit wide (HE155) or a 64-bit wide (HE622) high-speed memory bus to connect to the 2 MB on-board Local Cell Memory (SDRAM). Access into the SDRAM can be to any address. Any combination of byte, half-word, or word writes are allowed by the hardware.
Buffer Alignment
Not all DMA transfers are aligned to 32-/64-bit boundaries. The ASIC supports automatic handling of misaligned buffer transfers, reducing CPU utilization and improving data flow efficiency.
Scatter/Gather DMA Engines
The ASIC is capable of moving data into or from multiple fragments in memory. The DMA operation can scatter or gather the data, respectively, during the DMA process. This offloads copy operations from the host processor, increasing the host's efficiency and overall system performance.
Protocol Offload
The PCI-to-ATM adapters provide built-in hardware to calculate TCP checksum. These mechanisms are available to host system device drivers and protocol stacks to off-load these CPU-intensive tasks.
