10 Gigabit Ethernet Virtual Fabric Adapter for IBM
Most x3850 X5 and x3950 X5 systems include one dual-port 10Gb Virtual Fabric adapter.
The Emulex Virtual Fabric Adapter is an industry-leading performance and scalability per watt,
dual-port network adapter for 10Gbps Ethernet (10GbE) networks. It offers the benefits and
flexibility of I/O convergence in a single end-to-end solution. Protocol offload for stateless
TCP/IP and TCP Chimney provide maximum bandwidth with minimum use of CPU resources. It
achieves line rate 10Gbps performance with support for TCP/IP stateless offloads and TCP
Offload Engine (TOE) support. TOE reduces system processor utilization, providing increased
system performance and reducing overall system power requirements.
The adapter is based on the Emulex OneConnect Universal Converged Network Adapter
(UCNA) platform that also includes the capability for future upgrades to Fibre Channel over
Ethernet (FCoE) and iSCSI protocol offloads. By using a common infrastructure for Ethernet
and storage networks, data centers can reduce capital expense (CapEx) for adapters, switches
and cables, and operational expense (OpEx) for power, cooling and IT administration.
End-to-end data protection with hardware parity, CRC, ECC and other advanced error checking
and correcting ensure that data is safe from corruption.
Dual 10Gbps Ethernet ports:
• IPv4/IPv6 TCP, UDP checksum offload; Large Send Offload (LSO); Large Receive Offload;
Receive Side Scaling (RSS); IPV4 TCP Chimney Offload
• VLAN insertion and extraction
• Jumbo frames up to 9000 Bytes
• Preboot eXecutive Environment (PXE) 2.0 network boot support
• Interrupt coalescing
• Load balancing and failover support including adapter fault tolerance (AFT), switch fault
tolerance (SFT), adaptive load balancing (ALB), teaming support and IEEE 802.3ad.
Note: You must have either one SFP+ transceiver or one SFP+ direct-attached cable for each
of the two 10Gb ports on the adapter.
Dual Gigabit Ethernet Controller
The eX5 systems include one integrated dual-port Broadcom 5709C Gigabit Ethernet
controller, with TOE (TCP Offload Engine) acceleration support, as well as load-balancing and
failover capabilities between the two ports.
TOE support helps improve overall system performance by offloading TCP/IP protocol
processing from the system microprocessor to the onboard Ethernet TOE processor.
The controller also supports highly secure remote power management using IPMI 2.0, plus

and PXE (Preboot Execution Environment) flash interface. Optional PCI
adapters offering failover and load balancing between adapters are available for added
throughput and increased system availability.
Hot-Swap/Redundant Components
System availability is maximized through the extensive use of hot-swap and redundant
components, including:
• Hot-swap redundant hard disk drives and solid-state drives
• Hot-swap redundant cooling fans (three redundant pairs)
• Hot-swap redundant power supplies

Efficient Cooling
Six strategically located hot-swap/redundant fans, combined with efficient airflow paths,
provide highly effective system cooling for the x3850 X5 and x3950 X5 systems, known as
Calibrated Vectored Cooling. The fans are arranged to cool three separate zones, left,
center, and right, with one 120mm fan each in the left and center zones and a pair of redundant
30mm fans in the third zone. The left and center zones are redundant with fans contained in the
removable power supply units.
The fans automatically adjust speeds in response to changing thermal requirements, depending
on the zone, redundancy, and internal temperatures. When the temperature inside the server
increases, the fans speed up to maintain the proper ambient temperature. When the
temperature returns to a normal operating level, the fans return to their default speed. Why not
