3-8 Sun Netra CP3250 Blade Server User’s Guide • April 2009
3.5.8 Broadcom 5715C Gigabit Ethernet
The Broadcom 5715C Gigabit Ethernet chip used on the Sun Netra CP3250 blade
server provides two 10/100/1000 MBASE-T interfaces to the Zone 2 connectors. It
incorporates the media access control (MAC) and physical (PHY) layer functions for
the two LANs used as the ATCA base fabric.
3.5.9 Sun Dual 10-Gbit Ethernet/Quad 1-Gbit RGMII
Network Interface Chip
The Sun Netra CP3250 blade server is equipped with one Sun Dual 10-Gbit
Ethernet/Quad 1-Gbit RGMII Network Interface chip (Sun 10 GbE Multithreaded
Networking Technolgy) 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 Technolgy provides two 10-Gbit XAUI
Ethernet connections to the ATCA backplane 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 Technolgy also provides two 1-Gb RGMII
Ethernet connections to the Broadcom BCM5482H chip, which converts to SERDES
and routes the SERDES signals through an 8 port switch and providing two 1 Gb
LANS to Zone 3-RTM and to each AMC slot.
3.6 I/O Components
3.6.1 AMC Slot
The Sun Netra CP3250 blade server contains one AMC slot, which is available from
the front panel. The slot is a single-width, mid-height slot. If needed, AMC I/O
connectivity can be accessed from the front panel (depending on the AMC installed)
and through the optional advanced rear transition module.
The Sun Netra CP3250 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
8S2E2 cards, as defined by the same specification.
