5.4.6 Sun Dual 10-Gbit Ethernet/Quad 1-Gbit RGMII
Network Interface Chip (Sun 10 GbE
Multithreaded Networking ASIC)
The Sun Netra CP3220 blade server is equipped with one Sun Dual 10-Gbit
Ethernet/Quad 1-Gbit RGMII Network Interface chip that is specifically designed to
support multicore and multithreaded processor with minimum CPU load while
maximizing network I/O thoughput.
Sun 10 GbE Multithreaded Networking ASIC provides two 10-Gbit XAUI Ethernet
connections to the ATCA back plane extended fabric, where four lanes are driven at
3.125 Gbyte/sec (if the ATCA switch supports 10-Gbit Ethernet) or a single lane at
1.25 Gbyte/sec if the switch is a 1-Gbit Ethernet device.
Sun 10 GbE Multithreaded Networking ASIC also provides two 1 Gbit RGMII
ethernet connections to the Broadcom BCM5482H chip, which converts to SERDES
and routes the SERDES signals through and 8 port switch and providing two 1Gb
LANS to Zone 3-RTM and to each AMC slot.
5.5 I/O Components
5.5.1 AMC Slots
The Sun Netra CP3220 blade server contains two AMC slots, B1 and B2, which are
available from the front panel. Both slots are single-width, mid-height slots. If
needed, AMC I/O connectivity can be accessed from the front panel (depending on
the AMC card installed) and through the optional ARTM.
Each slot has one hot-plug connector for the AMC cards. The Sun Netra CP3220
blade server conforms to the PICMG Advanced Mezzanine Card AMC.0 specification
R1.0 ECR_002 D0.9, June 29, 2006, and supports AMC.1 Type 4E2 cards, as defined
by the same specification.
