The HP Flex-10 10Gb 2-port 552M is a Flex-10 10 Gigabit Ethernet (10GbE) mezzanine card for BL-c Gen8 servers that utilizes the Emulex BE3 controller. The HP 552M adapter supports Virtual Connect Flex-10, which allows each 10Gb port to be divided into four physical NICs to optimize bandwidth management for virtualized servers. The HP 552M optimizes network and storage traffic with hardware acceleration and offloads for stateless TCP/IP and TCP Offload Engine (TOE).

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
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.
Evolve 10Gb at your own speed! When paired with the HP Virtual Connect Flex-10 10Gb EthernetModules, 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.
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.
The HP 552M adapter support for NIC teaming helps IT administrators increase network fault tolerance and improve workload balance. These capabilities optimize availability, improve performance and help reduce costs.
For overall improved system response, the HP 552M adapter supports standard TCP/IP stateless 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), also known as TCP segmentation offload (TSO), allows TCP segmentation to be handled by the adapter rather than the CPU.
TCP/IP Offload Engine (TOE) moves the processing of data in the TCP protocol stack from the serverCPU to the network card, freeing CPU cycles for other duties.
