Ethernet Infrastructure
The fabric switch infrastructure is composed of
•
Broadcom StrataXGS®III Chip BCM56526 with 28 SGMII + 6 HiGig Port Gigabit Ethernet Layer-2/3 Switch
•
Three Broadcom BCM54680 OctalPHYs for copper based backplane links
•
Three Broadcom BCM8727 dual 10GbE PHYs for front panel 1/10GbE uplinks with Multirate SFP+ support
Line rate switching for all packet sizes and conditions is supported on following interfaces:
•
23x Link Ports to Node boards [10/100/1000Base-T via external Copper PHY]
•
1x Link Port to Fabric board [10/100/1000Base-T via external Copper PHY]
•
8 front panel uplinks:
•
6x 10GBase-X SFP+ uplinks to front panel
•
2x 1GBase-X SFP uplinks to the front panel, 2x 1G uplinks per port configurable to SGMII for 'Copper-SFPs'
supporting 10/100/1000Base-T operation
The CPCI interface numbering is according to the PICMG 2.16 Specification, labelled 1 to 23 (Node Slots) and F (other Fabric
Slot). The on-board management software identifies the interfaces as 0/1 to 0/24, continuing to 0/33 for the front panel
ports. The LED numbering on the front panel corresponds to this numbering scheme.
