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 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 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 Adapter provides support for several different types of teaming enabling IT
administrators to optimize availability, improve performance and help reduce costs.
