Performance
Product Features
Industry-leading throughput and latency performance
Supports Gen8 c-Class ProLiant BladeSystem servers
Type A Adapter Dual 10Gb ports provide up to 40Gb full duplex per adapter
Hardware acceleration and offloads for stateless TCP/IP and TCP Offload Engine (TOE)
802.1p, 802.1q, 802.1qau 802.3u, 802.3ad, 802.3ae, 802.3ap (10GBase-KX4), 802.3x and 802.3z
Jumbo frames support
Supports HP's Flex-10 technology that allows setting bandwidth from 100Mb to 10Gb in 100Mb
increments on up to four physical function NICs or Flex NICs per port when combined with the 10Gb
Flex-10 Virtual Connect module. Each FlexNIC is recognized by the server as a PCI-e physical
function.
Supports receive-side scaling (RSS) for the efficient distribution of network receive processing
across multiple CPUs in multiprocessor systems.
Includes 128 MB of onboard memory.
Supports the Preboot eXecution Environment (PXE)
Supports SR-IOV
Dual-port 10 Gigabit
Ethernet Throughput
(theoretical bandwidth)
The 20 Gbps full duplex Ethernet transfer rate per port (40 Gbps aggregate full duplex) delivers
outstanding network performance that improves response time and removes bottlenecks.
HP Virtual Connect Flex-
10 10Gb Ethernet Module
for the c-Class
BladeSystem
Evolve 10Gb at your own speed! When paired with the HP Virtual Connect Flex-10 10Gb Ethernet
Modules, take advantage of four Flex NICs, which are PCI Physical Function devices that are OS/Hypervisor
independent.
Server ROM recognizes them as individual NICs. Speeds can be set per NIC from 100Mb to 10Gbs in 100Mb
increments.
Three fold increase in number of network connections per port and up to four physical function NICs per
port. Ideal for virtualized server environment, especially for dedicated bandwidth application like virtual
machine migration from one physical server to another physical server.
Jumbo Frames
The HP 552M adapter support for jumbo frames (also known as extended frames) permits up to a 9K byte
maximum transmission unit (MTU), which is over five times the size of standard 1500-byte Ethernet frame.
Jumbo frames can help achieve higher throughput and better CPU utilization. Jumbo frames are
particularly useful for database transfers and tape backups.
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 or FlexNIC of the HP 552M
adapter to be assigned to a VLAN for added network segmentation and enhanced security and
performance. VLANs increase security by isolating traffic between users. Limiting the broadcast traffic to
the same VLAN domain also improves performance.
