1.1 Features

The Netra CP32x0 ARTM-10G is an advanced rear transition module (ARTM) for AdvancedTCA systems. It provides up to four 10GbE SFP+ and two 1GbE SFP (small form-factor pluggable) connectors on the ARTM faceplate that together provide the mechanical and electrical means to conduct high-speed data transfers with an ATCA node board.

The Netra CP32x0 ARTM-10G extends CPU and OS parallelism with its support for hardware-based flow classification and multiple DMAs. Using CPU thread affinity to bind a given flow to a specific CPU thread, the Netra CP32x0 ARTM-10G enables a one-to-one correlation of RX and TX packets across the same TCP connection. This functionality can help eliminate cross-calls and context switching to deliver greater performance while reducing the need for CPU resources to support I/O processing. The Netra CP32x0 ARTM-10G uses a Sun MAC controller to map the 10-Gigabit XAUI interface onto the ARTM form factor.

ATCA cards with proper Zone 3 connector pin-outs can route traffic to the ARTM interface resources via x8 PCIe and/or 10GbE XAUI channels. The Netra CP32x0 ARTM-10G includes two R-J45 management ports (RS-232 and 1GbE) and a Module Management Controller (MMC).

The Netra CP32x0 ARTM-10G is a 6U x 80mm single slot ARTM that supplies several high speed I/O connections. The prominent digital components include:

- Sun ASIC that converts PCIe to 10GbE XAUI and 1GbE

- 10GbE transceiver

- 1GbE transceiver

- MMC, with hotswap and LED control

- FRU ID serial EERPORM (the FRU ID is not a separate part but is embedded in the MMC controller)

- Temperature sensors

- Voltage sensors

- SPI flash memory

1.2 I/O PICMG Standards Compliance

The Netra CP32x0 ARTM-10G expansion ARTM is fully compliant with the PCI Industrial Computer Manufacturers Group (PICMG) specifications, PICMG 3.1.

##

1.3 I/O Interfaces

The Netra CP32x0 ARTM-10G mates to ATCA carrier blades via Zone 3 connectors in a fashion conforming to PICMG 3.0 ATCA specification, revision 2. Internally the Netra CP32x0 ARTM-10G provides circuitry to “bridge” between Zone 3 and the ARTM faceplate as follows in TABLE 1-1 and FIGURE 1-1.

### 1.3.1 External SFP Connections

The Netra CP32x0 ARTM-10G expansion supports up to six optical small form-factor pluggable (SFP) connections. These connections exchange high-speed Ethernet packet traffic with external equipment. See Appendix B for a list of compatible SFP modules.

#### 1.3.1.1 Features Common to all Ports

- IEEE 802.3ae 2002-compliant

- Networking I/O virtualization supporting Solaris LDOMS 1.0 software

- Hardware-based flow classification for extending parallelism and virtualization to networking

- Up to 16 receive DMA channels and up to 24 transmit DMA channels, multiple receive and transmit descriptor rings, and dedicated networking hardware resources (DMA, interrupts, buffer, and more) for each thread or strand

- CPU/thread affinity and CPU load balancing at L1, L2, L3, and L4

#### 1.3.1.2 1GbE Port Features

Both of the 1-Gigabit Ethernet ports (ports 1 and 2) are full duplex and use a SFP optical transceiver with a duplex high-level data link control (HDLC) fiber connector. Functional features of these ports:

- TCP and UDP checksum off load and CRC32C support

- L1 to L4 IPv4/v6 header parsing

- Jumbo frames support (up to 9216B)

#### 1.3.1.3 10GbE Port Features

All of the 10-Gigabit Ethernet ports (ports 3, 4, 5, 6) are full duplex and use a small form-factor pluggable (SFP+) optical transceiver with duplex LC fiber connector. Functional features of these ports:

- TCP and UDP checksum off load and CRC32C support

- L1 to L4 IPv4/v6 header parsing

- Jumbo frames support (up to 9216B)
