Optimized for
Virtualization
I/O Virtualization support for VMware NetQueue and Microsoft VMQ 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 561T 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 561T 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 561T 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 561T 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 561T Adapter supports Precision Time Protocol-ready (PTP).
Network Adapter
Teaming
The HP 561T 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
561T 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 561T 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 561T
adapter can also be managed by other applications with SNMP support.
