HP 700699-B21, 561FLR-T Specification
The HP Ethernet 10Gb 2-port 561FLR-T Adapter is a dual-port 10GBASE-T adapter, featuring the 10Gb Intel X540 Controller in
FlexibleLOM form factor designed for HP ProLiant Gen8 rack and tower servers. The HP 561FLR-T Adapter delivers full line-rate
performance across all ports with low power consumption, utilizing CAT 6A UTP (or better) cabling with distances up to 100 meters and
is backward compatible to existing 1000BASE-T infrastructure. Providing high performance Ethernet connectivity, this adapter is ideal
for virtual server and cloud computing environments. It supports enterprise class features (VLAN tagging, adaptive interrupt
coalescing, MSI-X, NIC teaming (bonding), Receive Side Scaling (RSS), jumbo frames, PXE boot) and virtualization features (VMware
NetQueue and Microsoft VMQ).
The adapter's support for HP Sea of Sensors 3D Technology enhances server performance by reducing energy consumption and
expense.

Converged Ethernet
Throughput
The HP 561FLR-T adapter delivers 20 Gbps full duplex Ethernet transfer rate per port, providing the
network performance needed to improve response times and alleviate bottlenecks that impact
performance of next generation data centers. 10Gb Ethernet bandwidth is ideal for high performance
computing, database clusters, and more.
Jumbo Frames
The HP 561FLR-T adapter supports jumbo frames (also known as extended frames), permitting up to a
9.5K 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 improve CPU utilization. These attributes are particularly useful for database transfer
and tape backup operations.
TCP/IP Stateless
Offloading
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.
The HP 561FLR-T Adapter TCP/IP stateless offloading capability.
MSI and MSI-X
Message Signaled Interrupt (Extended) provides performance benefits for multi-core servers by load
balancing interrupts between CPUs/cores. The HP 561FLR-T 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 561FLR-T
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 561FLR-T Adapter provides support
for 802.1Q (VLAN).

Optimized for
Virtualization
Intel® Virtualization Technology for Connectivity (VT-c) for I/O Virtualization supports VMware NetQueue
and Microsoft VMQ to help meet the performance demands of consolidated virtual workloads And reducing
CPU utilization.
Compliant with Single-Root I/O Virtualization (SR-IOV), accommodating multiple Virtual Machines (VMs) to
share single PCIe resources.
The HP 561FLR-T Adapter is SR-IOV ready, requiring firmware, software and OS support.
Checksum &
Segmentation Offload
Normally the TCP Checksum is computed by the protocol stack. By selecting one of the "Checksum
Offload" parameters, the checksum can be 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 561FLR-T 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 561FLR-T 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 561FLR-T Adapter has RSS capabilities.
Time synchronization
implementations (PTP)
Synchronization of system clocks throughout a network, achieving clock accuracy in the sub-microsecond
range, making it suitable for measurement and control systems.
The HP 561FLR-T Adapter supports Precision Time Protocol-ready (PTP).
Network Adapter Teaming
The HP 561FLR-T 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 561FLR-T provides support for several different types of teaming enabling IT administrators to
optimize availability, improve performance and help reduce costs.
Network Management
Management Support
The HP 561FLR-T adapter can be administered from HP Systems Insight Manager (SIM). The adapters can
be managed individually or in teams, providing SNMP based statistics for reporting purposes. The HP
561FLR-T adapter can also be managed by other applications with SNMP support.
