HP 570FLR-SFP+ Specification

The HP 570FLR-SFP dual-port 10Gb Ethernet SFP+ Onload server adapter is based on Solarflare's second generation 10GbE controller,
Solarflare™ SFC9020, and delivers unmatched message rates with low latency and jitter over standard Ethernet along with the lowest
CPU utilization and power consumption, enabling the industry's best performance and scalability for financial services and other
enterprise data centers.

The HP 570SFP+ has two SFP+ cages that enable connections with DACs as well as SR fiber optic modules. It supports high
performance networking features such as VLAN tagging, low latency interrupts, TCP and UDP checksum offloading, MSI-X, NIC teaming
(bonding), Receive Side Scaling (RSS), jumbo frames, and PXE boot.

Dual-port 10 Gigabit
Ethernet Throughput

The 20,000 Mbps full duplex Ethernet transfer rate per port (40 Gbps aggregate full duplex) delivers
outstanding network performance that improves response time and removes bottlenecks for the next
generation data center. 10 Gigabit Ethernet bandwidth is ideal for financial services, high performance
computing, database clusters, iSCSI storage, storage backups, grid systems, virtualization, server and I/O
consolidation, fabric consolidation, and more.

PCI Express Interface

The HP 570FLR-SFP+ Adapter is designed with an eight lane (x8) PCI Express bus based on the PCIe v2.0
standard.

Jumbo Frames

The HP 570FLR-SFP+ Adapter supports jumbo frames (also known as extended frames), permitting up to a
9K 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 greater CPU utilization. These attributes are particularly useful for database transfer and
tape backup operations.

TCP/IP Stateless
Offloading

For overall improved system response, the HP 570FLR-SFP+ adapter supports standard TCP/IP 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) or TCP Segmentation Offload (TSO) allows the TCP segmentation to be
handled by the adapter rather than the CPU. TCP, IP, UDP checksum offload, Large Send Offload
(LSO), TCP, Segmentation Offload (TSO). These features optimize host efficiency, leaving the CPU
available for other duties.

MSI and MSI-X & Interupt
Coalescing

Interrupt coalescing (interrupt moderation) groups multiple packets, thereby reducing the number of
interrupts sent to the host. This process can optimize host efficiency by improving peak throughput and
reducing CPU utilization.

Message Signaled Interrupt (Extended) provides performance benefits for multi-core servers by load
balancing interrupts between CPUs/cores. The HP 570FLR-SFP+ Adapter supports MSI and MSI-X.

802.1Q VLANs

IEEE 802.1Q virtual local area network (VLAN) protocol allows each physical port of the HP 570FLR-SFP+
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. The HP 560SFP+ Adapter provides support
for 802.1Q (VLAN).

Optimized for
Virtualization

I/O Virtualization support for VMware NetQueue, Microsoft VMQ and Virtualization Technology for
Connectivity (VT-c) help meet the performance demands of consolidated virtual workloads.

Compliant with Single-Root I/O Virtualization (SR-IOV), accommodating multiple Virtual Machines (VMs) to
share single PCIe resources.

The HP 570FLR-SFP+ Adapter is SR-IOV ready, requiring software and OS support.

Checksum &
Segmentation Offload

Normally the TCP Checksum is computed by the protocol stack. However, with the 570SFP+ the checksum
is computed by the adapter.

Segmentation Offload is technique for increasing outbound throughput of high-bandwidth network
connections by reducing CPU overhead. The technique is also called TCP segmentation offload (TSO) when
applied to TCP, or generic segmentation offload (GSO).

The HP 570FLR-SFP+ Adapter has Checksum and Segmentation Offload capabilities

IPv6

IPv6 uses 128-bit addressing allowing for more devices and users on the internet. IPv4 supported 32-bit
addressing.

The HP 570FLR-SFP+ Adapter supports IPv6.

Receive Side Scaling (RSS)

RSS resolves the single-processor bottleneck by allowing the receive side network load from a network
adapter to be shared across multiple processors. RSS enables packet receive-processing to scale with the
number of available processors.

The HP 570FLR-SFP+ Adapter has RSS capabilities.

Receive Flow Steering
(RFS)

Receive Flow Steering (RFS) acceleration improves processing efficiency by steering received packets to
the CPU core that is running the application that consumes those packets. Aligning I/O processing to the
CPU core running the application improves cache efficiency, CPU utilization, throughput and latency.

The HP 570FLR-SFP+ Adapter can accelerate RFS in hardware.

Network Adapter
Teaming

The HP 570FLR-SFP+ Adapter support for NIC teaming helps IT administrators increase network fault
tolerance and increased network bandwidth, The team of adapters can work together as a single virtual
adapter. The HP 560SFP+ Adapter provides support for several different types of teaming enabling IT
administrators to optimize availability, improve performance and help reduce costs.
