1.0 GENERAL INFORMATION
The XMC-6280 is a quad port 10 Gigabit Ethernet Unified Wire adapter XMC
module, optimized for cloud computing, HPC, virtualization, storage, and
other data center applications.
The heart of the XMC-6280
is Chelsio’s Terminator 4 (T4) ASIC.
The T4 ASIC
provides the highest 10GbE performance available and dramatically lowers
host-system CPU communications overhead with on-board hardware that
off-loads TCP/IP, iSCSI, FCoE and iWARP RDMA processing from its host
system. The XMC-6280 frees up host CPU cycles for useful applications. As a
result, the system achieves increased bandwidth, lower latency, and lower
power.
The XMC-6280 is an XMC module with eight high speed serial lanes
allocated to the XMC P15 connector. These lanes are used as an 8-lane PCIe
Gen 2 interface.
Four high speed Ethernet interfaces are routed from the ASIC to four SFP+
(Small Form-factor Pluggable) module connectors. Each SFP+ port is capable
of 10Gb/s full-duplex operation for both fiber optic and copper connections.
The XMC-6280 has a 256kb EEPROM, 32Mb of serial flash memory, and 5Gb
DDR3 SDRAM.
The serial flash memory contains the ASIC’s internal
microprocessor firmware code. The EEPROM contains hardware and PCIe
configuration information. On power up, the ASIC will copy the firmware
from the flash into DRAM. The 5Gb of DDR3 will contain the data buffers
and connection information to support up to 32K offloaded connections.
