The following manuals and part specifications provide the necessary information for in depth understanding of

the XMC-6260-CC board.

1.0 GENERAL INFORMATION

The XMC-6260-CC is a dual port XAUI 10 Gigabit Ethernet Unified Wire

adapter XMC module. This conduction cooled module is optimized for cloud

computing, HPC, virtualization, storage and other data center applications.

The heart of the XMC-6260-CC 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-6260-CC frees up host CPU cycles for useful applications.

As a result, the system achieves increased bandwidth, lower latency, and

lower power.

The XMC-6260-CC 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

2.0 interface.

Two high speed XAUI Ethernet interfaces are routed from the ASIC to a

secondary XMC P16 connector. Each XAUI port is comprised of four lanes,

each operating at 3.125Gbps for a total of 10Gb/s of data throughput in

each direction.

The XMC-6260-CC 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.

MODEL

Description

XMC-6260-CC-LF

Lead Free, RoHS compliant

Key Features

An XMC-6260 block diagram, found at the end of this manual, illustrates the

key features listed below.

Terminator 4 ASIC –A high performance purpose-built protocol

processor with a single processor data-flow pipelined architecture that

delivers up to one million connections and simultaneously supports

wire-speed, fully offloaded TCP/IP, UDP, FCoE, iSCSI and iWARP RDMA

on a single unified wire.

DDR3 SDRAM –Provides 64 Meg x 72-bit DDR3 SDRAM. The SDRAM is

linked to the ASIC device for the storage of the ASIC’s internal

microprocessor firmware, data buffers and connection information to

support up to 32k offloaded connections.

P15 High Speed Interface –Eight high speed serial lanes are allocated to

the XMC P15 connector. These lanes are used as an 8 lane PCIe Gen 2

interface to the T4 ASIC.

P16 High Speed Interface –Eight high speed serial lanes are allocated to

the XMC P16 connector. These lanes are used as a dual port XAUI

interface to the T4 ASIC providing a full-duplex 10GbE interface.

Applications

Data-Center Networking

oScale up servers and network-attached storage (NAS) systems

oLink servers in multiple facilities to synchronize data centers

oConsolidate local area networks (LAN), storage area networks

(SAN) and cluster networks

Cloud Computing

oVirtualization features to maximize cloud scaling and utilization

oRuns InfiniBand, Fibre Channel apps unmodified on internet

oCloud ready functional and management features

oQuality of Service (QoS) and Traffic management

Networked Storage

oEnable high performance NAS systems and Ethernet-based IP

SANs

oDevelop shared-storage systems providing both file- and block-

level services

High Performance Computing

oVery low latency Ethernet

oIncrease cluster fabric bandwidth

oDeploy Ethernet-only networking for cluster fabric, LAN and SAN

Hardware Requirements

The XMC-6260-CC supports architectures with PCIE (x4, x8, x16) gen 2 slots.

Note that running a 10Gb adapter on a PCI x4 slot is not recommended as

performance will be significantly reduced by the limitations of PCI. PCIe Gen

2 is also backwards compatible with Gen 1; however, the use of Gen 1 will

also result in significantly reduced performance.

Software Requirements

The XMC-6260-CC has been developed to run on 64-bit Linux based

platforms as well as 64-bit Windows systems and therefore it is a base

requirement for running the driver. To know more about the complete list

of operating systems supported by each driver, please refer to the driver’s

README information available from Chelsio’s website at

http://service.chelsio.com.

MAC Addresses

A MAC ID has been assigned to each of the two XAUI ports on the XMC-6260-

CC. The base address has been listed on a label on the bottom side of the

board. The following MAC address will be the next increment of 8. For

example, if the base MAC ID is 00:01:C3:00:7F:5A, the other MAC ID is

00:01:C3:00:7F:62.

2.0 PREPARATION FOR USE

Unpacking and Inspecting

WARNING: This board utilizes

static sensitive components

and should only be handled at

a static-safe workstation.

Upon receipt of this product, inspect the shipping carton for evidence of

mishandling during transit. If the shipping carton is badly damaged or water

stained, request that the carrier's agent be present when the carton is

opened. If the carrier's agent is absent when the carton is opened and the

contents of the carton are damaged, keep the carton and packing material

for the agent's inspection.

For repairs to a product damaged in shipment, refer to the Acromag Service

Policy to obtain return instructions. It is suggested that salvageable shipping

cartons and packing material be saved for future use in the event the

product must be shipped.

This board is physically protected with packing material and electrically

protected with an anti-static bag during shipment. However, it is

recommended that the board be visually inspected for evidence of

mishandling prior to applying power.

Card Cage Considerations

Refer to the specifications section for loading and power requirements. Be

sure that the system power supplies are able to accommodate the power

requirements of the system boards, plus the installed Acromag board,

within the voltage tolerances specified.

In an air cooled assembly, adequate air circulation must be provided to

prevent a temperature rise above the maximum operating temperature and

to prolong the life of the electronics. If the installation is in an industrial

environment and the board is exposed to environmental air, careful

consideration should be given to air-filtering.

In a conduction cooled assembly, adequate thermo conduction must be

provided to prevent a temperature rise above the maximum operating

temperature.

Board Installation

Remove power from the system before installing board, cables, termination

panels, and field wiring.

P15 Primary XMC Connector

The P15 primary XMC connector connects directly to the T4 ASIC via eight

lanes of Gen 2 PCI Express. The connector pin out, complies with the

ANSI/VITA 42.3-2006 pin definitions. Note that the XMC-6280 does not

support wakeup functionality and does not have a 3.3V aux line.

Non-Isolation Considerations

The board is non-isolated, since there is electrical continuity between the

logic and field I/O grounds. As such, the field I/O connections are not

isolated from the system. Care should be taken in designing installations

without isolation to avoid noise pickup and ground loops caused by multiple

ground connections.
