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 Wake

on LAN

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.

Integrated Virtualization

All models of the x3690 X5 support a USB 2.0 Flash Key installed preloaded with VMware

vSphere Hypervisor (formerly ESXi). Rather than management through a Service Console

based on a Linux operating system, vSphere Hypervisor relies on aggregate management tools,

including VirtualCenter, the Remote Command Line interface and the introduction of CIM for

standards-based and agentless hardware monitoring.

vSphere Hypervisor includes all the performance, scalability and compatibility features of a

hypervisor installed on disk, including full VMFS support across FC SAN, iSCSI SAN, and NAS,

and 4-way VSMP. Because it runs from flash memory, it’s extremely fast and ideal for diskless

configurations. It also offers enhanced security, because it runs without an operating system-

based console and is updated/patched much like firmware.

Ultra-Efficient Cooling

Five strategically located hot-swap/redundant fans, combined with efficient airflow paths,

provide highly effective system cooling for the eX5 systems, with N+1 redundancy.

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 simply run the

fans at 100% capacity all the time? For several good reasons: to reduce the ambient noise,

reduce the wear-and-tear on the fans and reduce the server power draw. The reduction in

ambient noise and power draw may be relatively minor for a single server, but if you have a

larger number of systems the aggregate savings in power and noise pressure can be significant.

In addition, the server uses hexagonal ventilation holes in the chassis. Hexagonal holes can

be grouped more densely than round holes, providing greater airflow through the system cover.

This cooling scheme is important because newer, more powerful processors generate a

significant amount of heat, and heat must be controlled for the system to function properly.
