LREC9812AF-2SFP+ PCI Express x8 Dual Port SFP+ 10Gb 10Gb Fiber NIC
(BCM57810S Based)
Overview
The LREC9812AF-2SFP+ is a dual-port 10Gb Ethernet adapter featuring the next generation BCM57810S single-chip solution from Broadcom in a PCIe 2.0 compliant form factor.
Leveraging Broadcom's market-proven architecture and software, the LREC9812AF-2SFP+ delivers full line-rate performance across all ports with low power consumption.
The LREC9812AF-2SFP+ supports enterprise class features such as VLAN tagging, adaptive interrupt coalescing,MSI-X, NIC teaming(bonding),Receive Side Scaling (RSS), jumbo frames, PXE boot and virtualization features such as VMware NetQueue and Microsoft VMQ.
Dual-port 10 Gigabit Ethernet Throughput
The LREC9812AF-2SFP+ adapter delivers 20Gbps full duplex Ethernet transfer rate per port (40 Gbps per adapter), 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 LREC9812AF-2SFP+ adapter supports jumbo frames (also known as extended frames), permitting up to a 9K 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 greater 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 LREC9812AF-2SFP+ Adapter by Broadcom offers 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 LREC9812AF-2SFP+ Adapter by Broadcom supports MSI and MSI-X.
802.1Q VLANs
IEEE802.1Q virtual local area network (VLAN) protocol allows each physical port of the LREC9812AF-2SFP+ 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 LREC9812AF-2SFP+ Adapter provides support for 802.1Q (VLAN).
Standard Features
TOE
TCP/IP Offload Engine (TOE) shifts the processing of data in the TCP protocol stack from the server CPU to the adapter's processor, freeing server CPU cycles for other operations.
Single-Root I/O Virtualization
Single-Root I/O Virtualization (SR-IOV) provides a mechanism to bypass the host system hypervisor in virtual environments providing near metal performance and server efficiency. SR-IOV provides mechanism to create multiple Virtual Functions (VFs) to share single PCIe resources. The device is capable of SR-IOV, and requires Server BIOS support, controller firmware, and OS support.
Optimized for Virtualization
I/O Virtualization support for VMware NetQueue and Microsoft VMQ help meet the performance demands of consolidated virtual workloads.
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 LREC9812AF-2SFP+ Adapter by Broadcom 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 LREC9812AF-2SFP+ Adapter by Broadcom 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 LREC9812AF-2SFP+ Adapter by Broadcom 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 LREC9812AF-2SFP+ Adapter by Broadcom supports Precision Time Protocol-ready (PTP).
Network Adapter Teaming
The LREC9812AF-2SFP+ 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 LREC9812AF-2SFP+ provides support for several different types of teaming enabling IT administrators to optimize availability, improve performance and help reduce costs.
Server Integration
The LREC9812AF-2SFP+ adapter is a validated, tested, and qualified solution.
This approach provides a more robust and reliable networking solution than offerings from other venders and provides users with a single point of contact for both their servers and their network adapters.
Configuration Utilities
Each LREC9812AF-2SFP+ ships with a suite of operating system-tailored configuration utilities that allow the user to enable initial diagnostics and configure adapter teaming. This includes a patented teaming GUI for Microsoft Windows operating systems. Additionally, support for scripted installations of teams in a Microsoft Windows environment allow for unattended OS installations.
LED Indicators
The colored LEDs on each port of the LREC9812AF-2SFP+ adapter indicate link status and link activity.
Preboot eXecution Environment (PXE)
PXE allows the server to boot over the network and download software residing in the network.
VMware NetQueue and Microsoft Virtual Machine Queue (VMQ)
VMware NetQueue is technology that significantly improves performance of 10 Gigabit Ethernet network adapters in virtualized environments.
Windows Hyper-V VMQ (VMQ) is a feature available on servers running Windows Server 2008 R2 with VMQ-enabled Ethernet adapters. VMQ uses hardware packet filtering to deliver packet data from an external virtual machine network directly to virtual machines, which reduces the overhead of routing packets and copying them from the management operating system to the virtual machine.
The LREC9812AF-2SFP+ Adapter by Broadcom support VMware NetQueue and Windows Hyper-V VMQ.
Network Management
Management Support
The LREC9812AF-2SFP+ adapter can be administered from Insight Manager (SIM). The adapters can be managed individually or in teams, providing SNMP based statistics for reporting purposes. The LREC9812AF-2SFP+ adapter can also be managed by other applications with SNMP support.
