Solarflare X2541 network adapter Quick Start Guide

1.1 Overview
The Solarflare XtremeScale™ X2541 is a single-port network adapter that delivers
benefits in application acceleration, ultra-low latency, security, precision timesynchornization/hardware timestamping, and highly efficient network traffic
processing for today’s enterprise, scale out, and software-defined data centers.

User Guide
For comprehensive installation instructions, configuration and tuning guidance, andAppFlex information please consult the Solarflare Server Adapter User Guide.
The Solarflare User Guide can be downloaded from https://support.solarflare.com

Drivers
Solarflare server adapters support the following OS distributions; RHEL, SUSE,Ubuntu, Debian, VMware ESXi, and Windows Server.
Drivers can be downloaded from https://support.solarflare.com

OnloadSolarflare server adapters also support Onload – a ‘kernel bypass’ accelerated userlevel TCP/IP network stack, providing extremely low latency. Onload links with theapplication using the standard POSIX BSD sockets API, meaning no modifications arerequired to the application being accelerated. Onload is enabled via AppFlex
technology activation.
To learn more about Onload please visit http://www.openonload.org

Precision Time Protocol
XtremeScale™ adapters are equipped with a Stratum 3 oscillator to support
hardware timestamping of PTP packets and server synchronization. Solarflare’s
Enhanced PTP is enabled via AppFlex technology activation, and can synchronize
multiple adapters to a PTP source.
Solarflare’s Enhanced PTP daemon is available from https://support.solarflare.com

1.2 Installing the adapter
Solarflare X2541 server adapters are compatible with Intel and AMD x86/x64 PCs
with 16-lane PCIe 3.1 (8GT/s), PCIe 3.0 (8GT/s), PCIe 2.0 (5GT/s) or PCIe 1.x (2.5GT/s) slots.
CAUTION: Servers contain high voltage electrical components. Before removing theserver cover, disconnect the mains power supply to avoid the risk of electrocution.
Before handling computer components, discharge static electricity from yourself bytouching a metal surface, or wear a correctly fitted anti-static wrist band.

Fitting the bracket
Solarflare X2541 adapters are fitted with a full-height bracket. A low-profile bracket
is also supplied for PCI Express slots that require this type of bracket.

Solarflare X2541 network adapter Quick Start GuideInserting the adapter in a PCI Express slot
The X2541 QSFP28 single-port adapter is a half-height, half-length, 16-lane PCIe 3.1
form factor adapter.
NOTE: The Solarflare X2541 server adapter requires a 16-lane PCI Express slot. Formaximum performance the adapter should be installed in a PCIe 3.1 or PCIe 3.0slot, but is compatible with PCIe 2.0 or PCIe 1.x.
Shut down the server and unplug it from its power source. Remove the server coverto access the PCI Express slots in the server. Locate a 16-lane PCI Express slot (referto the server manual if necessary) and insert the Solarflare server adapter. Secure
the adapter bracket in the slot.

CAUTION: The X2541 adapter must have sufficient air flow cooling – during normal
operation the minimum air flow required is 360 LFM@50C. Server cooling fansmust be fully operative to prevent damage to the adapter.

Cables and transceivers
Solarflare QSFP28 server adapters support a wide range of QSFP28 or QSFP+ direct
attach cables, SR optical transceiver modules, and QSA28 (QSFP28 to SFP28) or
QSA (QSFP+ to SFP+) adapters.
