HP FlexFabric 20Gb 2-port 650FLB Adapter
The HP FlexFabric 20Gb 2-port 650FLB adapter for ProLiant Gen9 server blades provides full-featured, high performance
converged 20Gb Ethernet that accelerates IT services and increases data center efficiency across a broad range of I/O intensive
enterprise, cloud and Telco workloads.
When connected to HP Virtual Connect FlexFabric 20/40 F8 Modules, the HP FlexFabric 650FLB adapter provides 20GbE
performance. It offers a rich set of offload technologies including overlay network tunneling and storage, increasing
virtualization performance and host efficiency. The HP 650FLB is a dual-speed adapter that can also operate at 10GbE when
connected to HP Virtual Connect Flex-10/10D Module or HP 6125XLG Ethernet Switch.
The HP 650FLB also supports RDMA over Converged Ethernet (RoCE) which increases host efficiency and lowers latency. RoCE is
supported with the HP 6125XLG, and other 10GbE switches.
Combining both the FlexibleLOM and Mezzanine adapters in a single BladeSystem Proliant server can provide up to 80Gbps of
converged bi-directional Ethernet bandwidth, helping to alleviate network bottlenecks.

Industry-leading throughput and latency performance
Supports HP's Flex-20 blade interconnect technology
Over eight million small packets/s, ideal for web/mobile applications, mobile messaging, and
social media
User configurable bandwidth settings when combined with the 20Gb Flex-20 Virtual Connect
module. From 100Mb/s to10Gb/s on up to four "Physical Function" NICs per port, in
increments of 100Mb/s for NIC. The combined bandwidth of NICs cannot exceed port
bandwidth i.e. 20 Gb/s.

Dual-port 20 Gigabit
Ethernet Throughput
(theoretical bandwidth)
The HP 650FLB adapter delivers 40,000 Mbps bi-directional Ethernet transfer rate per port (80 Gbps
aggregate bi-directional), providing the network performance needed to improve response times and
alleviate bottlenecks that impact the performance of next generation data centers. 20Gb Ethernet
bandwidth is ideal for high performance computing and database clusters.
HP Virtual Connect
FlexFabric 20Gb
Ethernet Module for the
c-Class BladeSystem
Evolve 20GbE at your own speed! When paired with the HP Virtual Connect FlexFabric 20Gb Ethernet
Modules you can take advantage of four FlexNICs, which are PCI Physical Function devices that are OS/
Hypervisor independent. In addition, take advantage of new storage I/O functionality making it a fullConverged Network Adapter (CNA)
-Server ROM recognizes them as individual NICs
-Speeds can be set per NIC from 100Mbps to 20Gbs in 100Mbps increments
-Threefold increase in number of network connections per port.
-Up to eight physical function NICs per adapter.
-Ideal for virtualized server environments, especially for dedicated bandwidth application like virtual
machine migration from one physical server to another.
Jumbo Frames
The HP 650FLB adapter supports Jumbo Frames, permitting up to a 9,200 byte (KB) transmission unit
(MTU) when running Ethernet I/O traffic. This is over 5X the size of a standard 1500-byte Ethernet
frame. With Jumbo Frames, networks can achieve higher throughput performance and lower CPU
utilization. These attributes are particularly useful for storage, database transfer and tape backup
operations.
MSI-X
Message Signaled Interrupt (Extended) provides performance benefits for multi-core servers by load
balancing interrupts between CPUs/cores.

802.1p QoS Tagging
IEEE quality of service (QoS) 802.1p tagging allows the adapter to mark or tag frames with a priority
level across a QoS-aware network for improved traffic flow.
802.1Q VLANs
IEEE 802.1Q virtual local area network (VLAN) protocol allows each physical port of the HP 650FLB
adapter to be separated into multiple virtual NICs for added network segmentation and enhanced
security and performance. VLANs increase security by isolating traffic between users. Limiting the
broadcast traffic to within the same VLAN domain also improves performance.
TCP/IP Stateless
Offloading
For overall improved system response, the HP 650FLB supports standard TCP/IP stateless offloading
techniques including:
TCP/IP checksum offload (TCO) moves the TCP and IP checksum offloading from the CPU to the
network adapter.
Large send offload (LSO), also known as TCP segmentation offload (TSO), allows TCP segmentation to
be handled by the adapter rather than the CPU.
RDMA (RoCE)
RoCE is an accelerated I/O delivery mechanism that allows data to be transferred directly from the user
memory of the source server to the user memory of the destination server bypassing the operating
system (OS) kernel. Because the RDMA data transfer is performed by the DMA engine on the adapter's
network processor, the CPU is not used for the data movement, freeing it to perform other tasks such
as hosting more virtual workloads (increased VM density). RDMA also bypasses the host’s TCP/IP stack,
in favor of upper layer InfiniBand protocols implemented in the adapter's network processor. The
bypass of the TCP/IP stack and the removal of a data copy step reduce overall latency to deliver
accelerated performance for applications such as Microsoft Hyper-V Live Migration, Microsoft SQL and
Microsoft SharePoint with SMB Direct.
Tunnel Offload
Minimize the impact of overlay networking on host performance with tunnel offload support for VXLAN
and NVGRE. By offloading packet processing to adapters, customers can use overlay networking to
increase VM migration flexibility and network scale with minimal impact to performance. HP Tunnel
Offloading increases I/O throughput, reduces CPU utilization, and lowers power consumption. Tunnel
Offload supports VMware’s VXLAN and Microsoft’s NVGRE solutions.
Single-Root I/O
Virtualization
Single-Root I/O Virtualization (SR-IOV) provides a mechanism to bypass the host system hypervisor in
virtual environments providing near metal performance and increasing server efficiency. SR-IOV
provides a mechanism to create multiple Virtual Functions (VFs) to share single PCIe resources. The
device is capable of SR-IOV, and requires Server BIOS support, controller firmware, and OS support.
HP Sea of Sensors 3D
Support for HP's Sea of Sensors which is a collection of 32 sensors that automatically track thermal
activity - heat - across the server. When temperatures get too high, sensors can kick on fans and make
other adjustments to reduce energy usage. What makes it better is the upgrade from all six fans
kicking on at one time to a new system where only one kicks on - the one in proximity of the area that
started heating up - thus reducing the amount of energy used for cooling.
Optimized for
Virtualization
I/O Virtualization support for VMware NetQueue and Microsoft VMQ help meet the performance
demands of consolidated virtual workloads.
iSCSI/FCoE Boot
The HP FlexFabric 650FLB supports iSCSI INT 13 Boot and FCoE Boot from SAN.
